Environmental management and governance approach

Description of the Environmental Management System

The management system in place complies with the international standards UNE-EN-ISO 14001:2015—initially certified in 2003—and European Regulation 1221/2009 (EMAS III), which has been adapted to Regulation 1505/2017 and Regulation 2026/2018  —registered in 2008 under code ES-CA-000028—and is integrated as part of the Organization’s system, which adopts the principles of environmental management as a fundamental pillar of its operations. This management system, along with the audits and reviews conducted by management, enables the Organization to maintain a dynamic approach to environmental management, always guided by the following basic principles:

  • Compliance with current environmental legislation.
  • Continuous improvement of the plant's environmental performance.
  • Pollution prevention.

Inspired by the philosophy of continuous improvement, it will be subject to the P-E-V-0 cycle (Plan - Execute - Verify - Optimize), and is supported by documents such as the Manual and General Procedures that respond to its interaction with the Corporate Departments and common between factories; as well as specific ones that reflect the particular operations and adapted to the legal requirements of each facility.

Organizational context

The organizational context of the Mataporquera plant is determined by internal and external issues that influence the ability to achieve the objectives of the Environmental Management System. The external issues are mainly grouped into: needs and expectations of external stakeholders, geographical location, business situation, economic situation, legal and other applicable requirements and others. While internal issues include, in addition to internal stakeholders, aspects of the business group, environmental aspects, the production process itself, technological changes, management practices and others. 

Determination of risks and opportunities

The analysis of risks and opportunities is performed using qualitative or quantitative criteria. In the case of risks associated with environmental aspects and legal requirements, quantitative criteria are preferably used, as far as possible. The identification of risks and opportunities is carried out after the evaluation of environmental aspects, verification of applicable legal requirements and definition of the context and expectations and needs of interested parties. When qualitative criteria are used, we try to ensure that they are consistent and homogeneous based on experience and knowledge of the particular context of each plant. Thanks to the combination of probability and severity of the impact, their prioritization and the type of preventive action to be taken are established.

Risks 

The context analysis identifies risks and opportunities, and actions are studied and planned. Specifically, the main risks identified are:

    • Fire risk: Following the incident in September, measures have been implemented to improve the fire safety system and enhance its effectiveness in both prevention and fire suppression.
    • Loss of energy efficiency in the furnace's heat consumption: Process audits have been conducted in collaboration with expert engineering firms, and an action plan has been developed to improve its efficiency.
    • Probability of complaints and exceedances due to particulate emissions: The replacement of the cooler filter and the replacement of 1,360 filter bags in the cement mill filter have reduced the risks associated with these sources. The risk of particulate emissions from the kiln filter and from the handling of powdered materials remains.
    • Increase in heavy metal emissions associated with co-incineration. A protocol for monitoring recovered waste has been developed to reduce the risk of heavy metals in Recovery .
    • Risks associated with the new 2021–2030 scenario in the CO2 emissions market. Decarbonization and biomass use targets are established as part of the 2021–2030 Energy Transition and Climate Neutrality Plan.
    • It is worth noting the decline in economic profitability of certain biomass streams due to the sharp rise in prices relative to fossil fuels.·        
    • Risks associated with the upcoming implementation of the Industrial Emissions Directive: Transposition is expected in 2026. The greatest risks identified are the new emission limits for NOx and particulate matter and the new methodology for validating continuously measured data.

Opportunities 

The main opportunities identified have been:

    • Develop the Capital Energy Agreement for the supply of electricity from wind farms to be built at the Mataporquera hub, as well as the PPAs, to reduce the cost of electricity supply while ensuring a high percentage of renewable energy in the electricity mix.
    • Conduct testing on white slag Recovery from foundries in our local area and process the necessary permits to recycle the used oil generated at our facilities.
    • Please comment on energy-saving projects that involve obtaining CAES in addition to improving energy efficiency.
    • Promote R&D&I projects focused on CO2 capture. We continue to collaborate with research centers. These initiatives can provide valuable insights into processes for reducing CO2 emissions into the atmosphere.

Dimension of the activity

Description of the main activity

The production process begins with the reception of limestone raw materials from the quarry, located next to the factory, in the municipality of Valdeolea, with an approximate surface area of 917,200 m2. The most relevant environmental impacts associated with quarrying are: visual impact, change in the morphology of the terrain, occupation of natural spaces, depletion of natural resources and impacts associated with quarrying, such as vibrations, noise and particle emissions, mainly. These previously homogenized limestones and marls, together with other raw materials of the same nature, give rise to raw meal, after a process of grinding and appropriate mixing.

This raw meal, heated to over 1,450ºC using petroleum coke, previously ground, and other alternative fuels (tires, wood, meat meal, rubber, plastic and cocoa husks) in a horizontal rotary kiln and a cyclone tower, gives rise to the intermediate product, clinker, consisting mainly of calcium silicates, which are responsible for the irreversible hardening of cement in contact with water and/or air. The most relevant environmental impacts associated with the manufacture of cement and mortar are: atmospheric pollution from the grinding and combustion processes, global warming, noise emissions and the depletion of natural resources such as fossil fuels and energy.

Its grinding, together with other additions and a setting regulator such as gypsum, in appropriate proportions, gives rise to cement, with specific chemical, physical and mechanical properties that are standardized according to the type of addition, from limestone to fly ash from coal-fired power plants or blast furnace slag, among others, and the fineness of the grinding. The final product, cement or mortar resulting from the mixture of cement and aggregates, is stored in silos for sale in bulk or subsequent bagging.

Energy use and management

 

Energy management

The transformations associated with the manufacture of clinker and cement, which include processes of grinding, mixing, firing and milling of raw materials, fuels and clinker, involve high energy consumption. This energy comes mainly from fuels - thermal energy - and electricity - electrical energy -. That is why our organization integrates to its Environmental Management System new energy efficiency control and auditing procedures under the UNE EN ISO 50001:2018 standard.

The fossil fuels commonly used in the manufacture of clinker are those derived from petroleum, such as coal, petroleum coke and fuel oil. Oil gas is also used in vehicles, generators and heating boilers. Electric power is used in the process for grinding, storage and metering of the raw material, fuels and final product. 

For several years now, the strategic policy of Grupo Cementos Portland Valderrivas on harnessing the energy contained in waste, partially replacing fossil fuels with alternative fuels—some of which have a high biomass content and are carbon-neutral in terms of emissions that contribute to global warming. Thus, at the Mataporquera plant, shredded tires (NFU), animal meal, olive pomace, solid waste-derived fuels (plastics, rubber, wood, paper, etc.), and fuel blending (mixtures of Hazardous liquid alternative fuels: a mixture of paints and solvents) have been used to replace petroleum coke and coal.

The consumption tables contemplate the following energy uses:

  • Electricity consumption column: In Factory indicates the electricity consumption referenced to the manufacture of the final product: cement + mortar. In Quarry it is the electricity consumption in crushing and transport referenced to the crushed stone.
  • Oil consumption with reference to clinker produced: This is the consumption of fossil fuels of oil origin: coal, coke and fuel oil.
  • Other consumption with reference to clinker manufactured: Consumption of alternative fuels used in the manufacture of clinker.
  • Oil consumption referenced to cement + mortar: This is the consumption of gas oil used in the factory for vehicles, generators and heating boilers.
  • Oil consumption referenced to crushed stone: This is the consumption of gas oil used in quarry vehicles.

Environmental management and control

Fuel consumption

The percentage of thermal energy replaced by waste-derived fuels with calorific value in 2025 has decreased compared to previous years, reaching 60.1% compared to 64.3% in 2024 and 64% in 2023. This decline was due to a drop in consumption caused by a fire at the storage and metering facility for solid alternative fuels used by the main burner.
Environmental improvement targets are set to achieve a 70% thermal contribution from alternative fuels. Modifications to the tower kiln facility are being studied, and work continues on optimizing the expert control system for the tower kiln calcination line to improve energy efficiency and increase the Recovery alternative fuels.

Electricity consumption

Specific electricity consumption has increased from 12.53 MWh per ton of cement in 2023 and 116.07 MWh per ton of cement in 2024 to 119 MWh per ton of cement in 2025. This consumption depends on the purchased clinker used in cement production.
The trend in relevant consumption by facility shows a decrease in Table 2024 vs. 2025
In 2025, improvements have been implemented at facilities to reduce electricity consumption in processes: replacement of balls in the cement mill, modification of the raw mill configuration, repair of refractory bricks in the kiln, implementation of the expert kiln control system, and replacement of compressor No. 1 in the tower, as well as replacement of electric motors with more efficient ones. These measures are being evaluated for eligibility for energy savings certificates (CAEs).

Note: Renewable energy is the sum of the substitution of biomass in kiln fuel and the MWh of renewable energy in the electricity mix. The use of biomass in clinker production was 25.4% in 2025, compared to 22.4% in 2023 and 22.1% in 2024. Biomass is a fuel with low calorific value, so its use requires a blend with other types of fuels with high calorific value, typically fossil fuels such as petroleum coke, fuel blending, tires, or coal. The improvement target for 2030 is set at achieving 35% biomass use. The percentage of renewable energy in the electricity generation mix is due to the signing of long-term supply contracts with photovoltaic plant operators. Additionally, the Mataporquera plant has signed an agreement with the company managing the wind farms currently under development at the Mataporquera hub to feed 100% of the renewable energy generated into the grid via its electrical substation. In 2025, 69% of the electricity mix came from renewable sources.

Water use and management

 

Water management

The sources of water supply used in our center are, on the one hand, the catchment of the Camesa river for cooling facilities and equipment, the public supply of the City of Valdeolea that supplies water for drinking use and, finally, the use of water from the quarry pond under authorization since 2023.

agualogo-ee81b73d

Environmental management and control

Between 2022 and 2025, there was a gradual increase in water consumption due to the need to irrigate the quarry to reduce dust emissions, primarily during the summer months. In 2025, there was also additional water consumption due to firefighting efforts at the storage and metering facilities for the main burner of solid alternative fuels.

Some of the significant environmental issues and risks identified in this Statement include complaints from residents of Mataporquera regarding dust pollution, with the quarry being one of the main sources of this problem during the summer. The way to reduce emissions is by watering the vehicle access roads and the material piled up at the quarry faces prior to the crushing process, which involves water consumption that depends on dust emissions and wind direction.

Waste water discharge management

Wastewater management

Our center channels the discharge of water into the Camesa River, carrying out controls every four months at all authorized discharge points to check that their characteristics are adequate to the discharge regulations and in order to preserve the quality of the receiving environment.

The sanitary water from the factory is treated in our wastewater treatment plants with physical and chemical treatment. The sanitary water from the quarry passes through a water treatment plant before infiltration into the ground.

Rainwater from the factory undergoes a process of settling and separation of oils and fats. Water from the cooling system can be discharged, although the closed-loop system prevents this discharge, which would only occur in emergency situations. Rainwater from the quarry is directed to the settling pond before being discharged into the Camesa River. 

Compliance with the limit values established in the Environmental Authorization of the Mataporquera factory has been guaranteed, and no exceedance of these values has been recorded. The discharge limits have also been complied with in the inspections carried out by technicians from the Duero Hydrographic Confederation to verify the quality of the water discharged.

The maximum value of the four campaigns carried out for each pollutant and discharge point is presented due to its significance as it is the closest to the discharge limit value.

Atmospheric emissions

 

Emissions management

Particulates and combustion gases are the most characteristic atmospheric emissions of our activity. Emissions generated during the handling, transport, storage and treatment of powdery materials are emitted through channeled and diffuse sources, while combustion gases are emitted through the kiln chimneys, the most characteristic compounds emitted beingCO2, NOx and SO2, together with other minor pollutants. The emission of pollutants is monitored by ECAMATs (Entities Accredited by the Government of Cantabria for Environmental Monitoring) or the continuous systems installed in the factory chimneys, following the requirements of an Environmental Monitoring Plan that complies with the Integrated Environmental Authorization.

Emissionslogo-7bdac1d8

Environmental management and control

Emissions from channeled sources

At the Mataporquera plant, seven emission sources are monitored via chimneys: two from the clinker manufacturing process and the cooling kiln, and the rest from the fuel grinding, cement grinding, stone crushing, and cement and mortar bagging processes. All of these are equipped with baghouse filtration systems, which represent some of the Best Available Techniques in the industry. Furthermore, three of them—the kilns, the cooler, and the cement mill—are equipped with continuous particle measurement systems; in the case of the kiln, they also measure flue gas emissions of NOx, SO₂, CO, and TOC. 

Particulate matter emission

Particulate emissions continue to be considered a significant environmental concern, and multi-year measures have been established to reduce the level of settleable particulates in the surrounding area. Notable actions include replacing the filter in the cooler and changing 1,360 filter bags in the cement mill.

In 2025, there were no instances of localized sources exceeding the atmospheric emission limit value. Emission levels at the main sources—the kiln, cement mill, and cooler—remained consistent with previous years.  

Emission of combustion gases

In the combustion process that takes place in the kiln for clinker production, mainly carbon dioxide, sulfur dioxide and nitrogen oxides are generated, together with other minority pollutants: HCl, Hf, total organic compounds, heavy metals and dioxins and furans. 

Combustion gas emission values comply with the legal limits established in the Integrated Environmental Authorization. Continuously measured emissions of the main pollutants SO2 and NOx remain constant compared to previous years. A 40-90% reduction in the emission of these pollutants has been achieved since the Integrated Environmental Authorization was obtained in July 2005. The use of alternative fuels has been the cause of the decrease in SO2 and NOx emissions. In the case of SO2, this is due to the reduction in the clinker kiln's contribution, and in the case of NOx, it is caused by the effect on the thermal balance in the kiln due to the mix of fuels with different calorific power.

Diffuse source emissions

The minimization of emissions resulting from the transfer and movement of powdery materials has been achieved by adopting a series of preventive measures such as paving in circulation areas, conveyor belt fairings, suction devices at transfer, loading and unloading points, wind protection screens and road watering, among others.

For the inspection of air quality, a PM10, NOx, SO2 immission campaign was carried out in the Valdeolea Town Hall square, which is complemented with those carried out by the Autonomous Administration in order to control the air quality of the environment in all its emission sources, confined and diffuse, as well as the possible migration of pollutants from emission sources in nearby towns.

Additionally, other sedimentable particles campaigns were carried out; one in the factory and two in the quarry for one month. All controls gave results below the legal reference values. The tables show the highest value measured for its impact on the perception of particles in the environment.

Other emissions 

Emission levels of minority gas pollutants have been maintained at values below the legal limits.  

It should be noted that data on 37 pollutants are reported annually to the State Registry of Emissions and Pollutant Sources (PRTR Spain) in the form of pollutant loads from piped emissions. In 2025, CO andNOx were the only pollutants whose pollutant loads exceeded the reporting threshold.

CO2 emissions

 

Confined greenhouse gas emissions

In 2025, 313,978 tons ofCO2 were emitted into the atmosphere, resulting from the decarbonation of limestone—through the transformation of limestone into calcium oxide at the high temperatures of the process —and the combustion process—through the oxidation of carbon in fuels in the presence of oxygen—which amounted to 724 kgCO2 per ton of clinker.

The increase in emissions in absolute terms is a direct result of the increase in production. However, the decrease in specificCO2 emissions is significant, thanks to improved furnace energy efficiency and the increased use of biomass and decarbonized material. 

TheCO2 allowance for 2025 has remained at 312,098 metric tons ofCO2, which corresponds to 100% of the activity level reference value (HAL).

Note: The "Scope 1" designation refers only to direct emissions verified for the CO2 market (ETS).

Waste production and management

 

GenerWaste generation

The cement manufacturing process does not give rise to the generation of waste, which is derived from facility maintenance activities, construction work and building cleaning, among others. The management criteria established are based on minimization in the generation process, reuse and recycling, with internal segregation and appropriate external management for each type of waste. 

The material generated during maintenance of the interior of the kiln and tower, as well as during the cleaning of facilities and access roads, is reused as raw material for clinker production, as it consists of a mixture of the raw materials used in the clinker and cement manufacturing processes. 

The Integrated Environmental Permit establishes reference quantities for each type of waste generated. In 2025, the quantities of scrap metal (254,230 metric tons generated compared to the 200,000 metric tons specified in the Permit) and wood (47.96 metric tons compared to 40 metric tons) were exceeded due to the waste generated by the September fire. The reference value for paper and cardboard (48.84 metric tons versus 40 metric tons) was also exceeded due to the disposal of obsolete cement bags from the bagging facility, which has been inactive since 2016. Refractory brick also exceeded the threshold (92.02 metric tons compared to 40 metric tons) due to the removal of obsolete material from the warehouses.

Aqueous cleaning fluids, which also exceed the reference value, are used in the auto repair shop to clean parts during maintenance work.

Looking ahead to 2024, there is also an increase in the amount of waste sent to landfills, driven by the disposal of replaced filter bags from the cooler and cement filters, as well as debris from the September fire.

Theremaining waste is delivered to an authorized waste management company with which a treatment contract has been established, and each delivery is documented as required by law

Environmental management and control

The waste minimization measures described in the 2022 EMAS Environmental Statement include the modification of the management system for rags generated in maintenance operations, changing to a system of rags for rent that are collected separately and, after an authorized cleaning process, are reused in our activities.

In 2026, there will be an increase in the generation of Hazardous waste Hazardous two unusual circumstances: First, the managed cloth rental system has been suspended because it did not meet the required quality specifications. On the other hand, predictive maintenance operations will be carried out on the clinker kiln filter in the coming years, which will also increase the number of filter bags managed as Hazardous waste.

In an effort to minimize Hazardous waste, Hazardous continuing with the project to reduce used oil. Once the Integrated Environmental Permit for this new Recovery has been obtained, we expect to secure the greenhouse gas emissions permit in 2026, prior to the revision of the Monitoring Plan.

Follow-up of the waste minimization plan

In 2025, the reduction in Hazardous waste generation continued; 16,688 tons were generated this year, compared to 21,037 tons in 2024 and 30,426 tons in 2023. This decrease was due to a reduction in the generation of contaminated soil resulting from spill cleanup operations. In 2025, the rest of the waste was generated in typical quantities, and the management system for rags impregnated with hazardous substances continued. 

In the case of Hazardous waste, excluding plant material reused by the quarry for clinker production, 331.04 tons were generated in 2024, compared to 203.23 tons in 2023. The increase in the generation of wood, scrap metal, and waste sent to landfills was driven by waste management following the fire at the storage and dosing facility for solid alternative fuels for the main burner.

Recovery . Recovery of Hazardous waste Hazardous 49.8% of Hazardous waste were sent for recycling and Recovery .

It is important to note that all Hazardous waste Hazardous generated during corrective or preventive maintenance activities or as part of general repairs.

If the material reused in clinker production is not taken into account, the amount of waste generated is 2% higher than the limits set in the Integrated Environmental Permit due to waste generated by the fire, the emptying of the bagged material storage area, and obsolete refractory bricks .

Management of raw materials and resources

Management of material resources

The clinker, cement and mortar manufacturing processes require the consumption of large quantities of raw materials. The main raw material used is stone extracted from the surrounding quarries, although there are also other materials that are essential in smaller quantities to achieve an adequate composition of the intermediate and final products, with external origin. For the most part, these are also natural raw materials from other operations, but circular economy principles are also applied and alternative raw materials from other industrial processes are used. Raw material consumption values depend on variations in production and consumption of alternative materials.

The materials included in each category are:

Natural raw materials used in clinker production: Loam , limestone, silica sand, fluorite, limonite, iron silicate, limestone sand, and limestone waste.
Secondary raw materials in clinker production: Molding sand, slag, construction and demolition waste, cement sludge and plant cleaning waste, iron scale.
Natural raw materials in cement manufacturing: Limestone, clinker, gypsum, ferrous sulfates, pozzolan, and additives.
Secondary raw materials in cement manufacturing:Flyashand blast furnace slag.
Natural raw materials in mortar production: Cement, aggregates, and lime.

Environmental management and control

In recent years, the Mataporquera plant has continued to explore options and the availability of materials to replace these natural raw materials with secondary raw materials—waste from other activities—as a means of reducing and optimizing its operations. Recovery practices Recovery a number of environmental benefits, including a reduction in the extraction of natural raw materials and the amount of waste sent to landfills, provided that they do not introduce components that affect product quality or the safety of workers and the environment.

Decarbonated raw materials have been included due to their effect on reducing CO2 emissions, such as limestone sand and limestone waste, construction and demolition waste, cement slurry, and facility cleaning waste. The use of alternative raw materials in clinker production has remained constant.
In cement production, the use of raw materials depends on the type of cement manufactured and the percentage of clinker consumed, in accordance with the UNE 197 series of standards.
In the case of mortar, raw material consumption ratios remain unchanged, and no alternative materials are used.

Biodiversity indicators

The manufacturing facilities occupy a built-up area of 39,507 m2 , which includes the mortar plant with a built-up area of 1,678m2 . The adjacent quarry occupies a constructed area of 2,883m2 and an operating area of 777,200m2. The main impact of our activity on the landscape is the exploitation of natural resources in the raw material supply quarry, and the Group has defined as a future challenge the "development of integrated management criteria for the restoration of quarries and the promotion of biodiversity".

The area currently restored is 11,050m2, and actions are established annually to comply with the restoration requirements included in the Work Plan.

In 2025, no restoration work was carried out because there were no available areas due to the quarry’s operating system, which expands the working faces in a radial pattern to continue mining downward once the boundary surrounding the entire quarry is reached. Vertical mining is limited by the water table.

Indicators and impacts

In 2026, it is important to highlight the environmental impact of the fire at the storage and Recovery facility Recovery solid alternative fuels serving the main burner. The fire generated wood, scrap metal, and inert material in quantities exceeding those of normal operations. It also resulted in emissions and wastewater discharges typical of an emergency and firefighting situation, and an increase in the consumption of captured water was observed.

The fire has also led to a shift away from biomass fuels toward fossil fuels.

The factory’s greenhouse gas emissions trajectory for 2025 was on track to achieve an emissions factor of less than 722 kg of CO2 per ton of clinker, which would have meant that the facility would meet the criteria of the European Taxonomy to be considered aligned with climate change mitigation.

Following the fire, a plan is being implemented to improve the fire prevention and suppression system, along with a comprehensive review of the Self-Protection Plan.

Sound emissions

Noise emissions in the surroundings of the manufacturing facilities generate, as an impact, nuisances to the population and fauna. In the case of the Mataporquera factory, located in the center of the municipality and very close to residential dwellings, a series of actions have been undertaken to minimize this impact and achieve noise emission levels below the established VLE.

A measurement campaign is conducted annually at representative locations on the outskirts of the city to ensure compliance with the legal requirements established for the factory. All measured values are below the limit values, both during the day and at night.

Environmental aspects and impacts

Environmental aspects and impacts

The identification of environmental aspects is based on an analysis of the processes, facilities and products of the factory and quarry with a life cycle approach of the manufactured products. This identification, objective and quantitative, takes into account possible interactions with the environment - soil, water, atmosphere, natural environment, socio-economic environment, population, etc. - as well as normal and abnormal operating and functioning conditions, potential accidental or emergency situations, indirectly generated aspects and those that may derive from past activities, aware of the importance of adopting preventive measures at the source of our actions.

Aspectoslogo-67d487c3

Description of the most important and significant environmental aspects

The evaluation of environmental aspects is a starting point for the revision of the System and for the definition and updating of operational control procedures, and those for action in the event of potential accidents and emergency situations. The evaluation carried out annually on environmental aspects, in general, is established on the basis of a series of definitive environmental criteria as indicated.

  • Hazard or level of environmental impact of the aspect.
  • Quantity or volume of the environmental aspect.
  • Complaints received from stakeholders and legal non-compliance.
  • Severity or level of severity of the impact, generally associated with the intrinsic and objective hazard.
  • Probability, frequency or recurrence with which the aspect occurs.
  • Capacity to influence economic, technical or human resources to carry out actions for prevention, control and correction of the aspect.

Based on the evaluation carried out, the significant environmental aspects with the greatest impact are determined and which, therefore, have a score higher than that established as significant, in accordance with the criteria indicated. Based on these, the activity plans its operational control and improvement objectives.

Direct environmental aspects are those generated as a result of the activities of the factory and quarry over which there is full control of their management. Grouped according to their environmental vector, the following environmental aspects have been identified and evaluated under normal and abnormal conditions.

Indirect environmental aspects are those aspects derived from the factory's activities, products and services over which there is no full control of their management. The following have been identified and evaluated as environmental aspects to be taken into account:

  • Greenhouse gas emissions as a result of the transportation of purchased products.
  • Greenhouse gas emissions from electricity consumption.
  • Packaging waste placed on the market once it has been used.

The assessment is based on the following environmental criteria: quantity—compared to the previous year—and potential for impact—based on the possibility of implementing measures to reduce them. A comparison of environmental management data from 2025 with that from 2024 has identified emissions, discharges, and waste generated by the fire, as well as water consumption, as significant factors.

To minimize the risk of fire, the Self-Protection Plan is being reviewed, and improvements are being made to the fire prevention and control system.

Goals have also been set to minimize the water footprint and reduce leaks in older drinking water service lines.

Environmental improvement planning

Target Planning

The environmental program is the tool for minimizing environmental impacts as far as possible, starting with the significant ones. It is prepared based on the basic principles established in the Environmental Policy and is updated annually. For planning purposes, we take into account the results of the evaluation of aspects, risks and opportunities, legal requirements, non-conformities and incidents, the opinion of interested parties and technological options for implementing improvement opportunities.

The modernization and continuous improvement of our production facilities are the basis for the reduction of the environmental aspects of our process, through the implementation of the best available techniques for the prevention, control and minimization of pollution.

In 2025, the following investments were made to minimize environmental and energy-related risks:

  • Chiller Coil Filter
  • New AR600 unit for the automatic measurement system used to monitor SO2, NOx, and humidity in furnace gases.
  • Oven expert system.

Good environmental management practices

Ecodesign and life cycle analysis

Life Cycle Assessment (LCA) of a product, process or technology is a methodology that attempts to identify, quantify and characterize the different potential environmental impacts associated with each stage of a product's life cycle. The LCA provides valuable information that allows the industry and users to make decisions aimed at improving the environmental performance of processes and products.

The cement sector, as a sector sensitive to sustainable development, has developed a life cycle analysis through AENOR's Global EPD Program, which has resulted in sectoral environmental product declarations (EPD).

 Thus, the cement industry evaluates its impact, manages the use of different types of waste as raw materials or fuels, controls the destination of packaging, and monitors its process in search of the best environmental performance.

 In order to promote transparency, the company has decided to draft and verify the Environmental Product Declarations for the cements it sells at all its plants in Spain. This work, carried out in 2025, culminated in the validation and publication of the six cements produced at the Mataporquera plant: CEM I 42.5 R, CEM I 52.5 R, CEM I 52.5 N (alkali-reduced), CEM II/A-L 42.5 N, CEM II/B-L 32.5 N, and CEM III/B 32.5 N-SR. 

The GlobalEPD Declarations have been issued in accordance with the GlobalEPD-RCP-003 Cements Rules issued in accordance with the Rules contained in the UNE-EN 16908:2019+A1:2022 Standard. All environmental declarations are in accordance with European Standard EN 15804.

 Reinforcing its commitment to the sustainability of its products, Cementos Portland Valderrivas has obtained the “sustainable” N mark (Ns mark) certification for all its cements. This mark is an evolution of AENOR’s traditional N quality mark and represents a new sustainability certification standard for industrial and construction products.

The Ns mark is the first certification in Spain that guarantees that a product is sustainable from an integral approach, evaluating technical and performance quality, environmental impact, social responsibility and corporate governance.
