Evolution of production activity

The wide range of products manufactured in Monjos allows for the ideal selection of cement type based on the end use. The cements currently on the market, which include 10 grades, are certified with the AENOR Product Certification "N" markand theCE marking, complying with the UNE-EN 197-1 and UNE-EN 197-2 standards. Some cements also holdAFNOR's NF certification.

In line with the sector’s goals to achieve climate neutrality, efforts are underway to manufacture cements with a lower carbon footprint, thereby actively contributing to the decarbonization of the industry. These new products, Types II and III, incorporate a higher proportion of active additives to replace clinker, which is the primary source of emissions in the manufacturing process.  In 2025, two new, more sustainable cements were certified: CEM III/A 42.5 N/SRC and CEM II/B-M (S-L) 42.5 R with slag admixture, both designed to reduce environmental impact without compromising product quality.

In 2025, clinker production fell by approximately 20% compared to the previous year, mainly as a result of a four-month shutdown of the highest-capacity kiln, caused by the implementation of the investment in the new grate cooler. Despite this reduction, total cement production remained at levels similar to the previous year, with lower bulk product shipments, aligning operations with the actual performance of the Catalan market, which in 2025 was characterized by subdued cement demand. 

Our cements have a Safety Data Sheet (SDS), which provides key information for a safe and responsible use of the product. This is especially important because of its irritant nature due to its alkalinity.

Environmental management and control

In 2025, there was a decrease in total energy consumption (fuels and electricity), with the decline being more significant in fuel consumption. This decrease is primarily due to reduced furnace operation resulting from a four-month shutdown of Furnace 5E—the one with the highest capacity—to replace the satellite cooler with a more efficient grate cooler. Likewise, the graph also shows a reduction in the consumption of alternative fuels, associated with furnace shutdowns due to instabilities in the production process.

On the contrary, the data show an increase in the electricity consumption ratio. This increase is related, on the one hand, to the production of cement with active additives that require longer grinding times to ensure equivalent performance, and on the other hand, to consumption associated with major investments made during this period. The shutdown of kiln 5E for several months has also influenced the calculation of this ratio.

Fuel consumption

The use of alternative fuels containing biomass is a key strategy in the fight against climate change, as they are considered carbon-neutral in terms of greenhouse gas emissions and allow for the partial replacement of fossil fuels. In this context, the Cementos Portland Valderrivas group integrates both the fight against climate change and the promotion of the circular economy into its strategy, committing to the gradual incorporation of these alternative fuels.

Recovery from waste in cement plants is a safe and effective solution that reduces greenhouse gas emissions, conserves non-renewable resources, and prevents waste from being sent to landfills. This process is carried out under strict environmental controls, ensuring the protection of human health and the environment, while moving toward more sustainable production. For more information, visit: www.recuperaresiduosencementeras.org.

The Monjos facility is registered in the Catalonia Waste Management Registry under code E-1165.10, underscoring its commitment to Recovery .

In 2025, the plant achieved a 34.4% energy substitution rate by using the alternative fuels described in the previous section. All of these fuels come from waste that could not be reused or recycled and would otherwise have ended up in a landfill. In addition, grape pomace and grape seeds—materials from the agricultural industry that are 100% biomass and have a high calorific value—have been used as fuels. 

Electricity consumption

Significant investments are currently being made at the plant to improve the energy efficiency of the production process and reduce specific electricity consumption. At the same time, the company has adopted a more sustainable energy mix, prioritizing the use of electricity from renewable sources, in line with a responsible energy transition.

The effects of these investments, combined with the improvements resulting from the energy targets set for 2025, are expected to take hold starting in 2026, contributing to a reduction in the kWh/ton of manufactured product metric.

Evolution of specific metrics and ratios

Units of energy consumption in MWh and their ratios associated with the activity.

Note: Renewable energies are considered to be those from the use of biomass as fuel in the clinker kilns, and electricity contracted with guaranteed renewable origin within the energy mix.

Environmental management and control

For years, the Monjos plant has been working on responsible and efficient management of this resource. Facilities have been improved to reduce consumption and, as a priority, wastewater from the Alcoholera Catalana company is reused in the conditioning of gases before passing through the sleeve filters, which represents the largest consumption of water in the facility.

In 2025, the increase in water consumption was primarily due to the lifting of the restrictions imposed over the previous two years under the Drought Decree, which allowed for increased irrigation of roads and restored areas. Additionally, there was higher water consumption for human use as a result of the increase in staff associated with the implementation of new investments. This increase was managed by maintaining measures to control and monitor water consumption, while promoting the efficient use of this resource at all times.

On a quarterly basis, the volumes of water consumed are declared to the Agència Catalana de l'Aigua in accordance with Decree 47/2005, of March 22nd.

Evolution of specific metrics and ratios

Environmental management and control

To guarantee the quality of the receiving environment, periodic analyses are carried out on the water discharged into the sewage system, the municipal wastewater treatment plant (WWTP), and the water discharged into public waterways. The self-monitoring parameters, as well as the sampling frequency and limits are defined in the facility's Integrated Environmental Authorization.

Throughout 2025, all limits set forth in the Environmental Permit were met in the internal tests conducted by an accredited laboratory, as well as in the inspections carried out by the Catalan Water Agency.

The results of all inspections are reported annually to the government during the first quarter of the year, and every four years, the Water Use and Pollution Report (DUCA) is submitted to the Catalan Water Agency. The most recent report was submitted in December 2024.

Public waterway receiving the discharge: Sewage system: Vilafranca del Penedès municipal wastewater treatment plant / Public watercourse: River Foix

Environmental management and control

In order to minimize the environmental impact of the activity, specific measures have been implemented to prevent and control gas and particle emissions. These actions are based on the use of Best Available Techniques, periodic and continuous emission controls at localized sources, preventive filter maintenance, preventive measures to minimize diffuse emissions and air quality monitoring.

In addition, emissions are strictly controlled and monitored, ensuring legal compliance and promoting continuous improvement in environmental performance.

Particulate matter emissions

To ensure the proper functioning of the particulate filtration systems, a regular preventive maintenance plan has been established for all emission sources. In addition, every two years, an accredited monitoring body verifies compliance with emission limit values at the 31 most significant sources—which account for 90% of the total flow—through spot checks of particulate emissions. The furnace sources are subject to stricter continuous monitoring and are connected to the XEAC (Catalan Atmospheric Emissions Network).

In 2025, isolated instances of exceeding the emission limit value were detected at two points in the cement grinding and clinker transport stages. However, the overall assessment of legal compliance is conducted using the virtual point, in accordance with Article 6.2 of Royal Decree 815/2013. According to this methodology, the virtual emission concentration was 4.8 mg/Nm3, significantly lower than the limit value applicable to the plant (16.9 mg/Nm3).

Flue gas emissions

Emissions generated during the combustion process in clinker kilns are monitored using continuous emission monitors connected to the regulatory agency via the XEAC, which enable continuous monitoring of the following pollutants: NOx, SO2, CO, particulate matter, HCl, total organic carbon (TOC), NH3, and Hg. Emissions of other minor pollutants are monitored through quarterly spot measurement campaigns.

In 2025, all pollutants continuously monitored at the three emission points associated with the clinker kilns complied with the emission limit values established in the Environmental Permit. With regard to periodic monitoring, a single instance of exceeding the Cd+Tl limit value was recorded in kiln 5E (Vila side) during the first quarter of 2025. Following an analysis conducted jointly with the monitoring agency and the Air Monitoring and Control Service, it was concluded that the result obtained for the concentration of these metals is invalid due to a measurement error.

Specific measures to reduce and control emissions are implemented for the main air pollutants generated during the process:

• NOx: emissions characteristic of the furnace conduction that are controlled by ammonia water injection.
• SO2: Its emissions depend on the composition of the raw materials; therefore, they are minimized by properly blending stone from different quarry areas.
• CO2: Reducing the emissions ratio per ton of clinker produced is facilitated by Recovery from alternative fuels containing biomass. However, in 2025, an increase in the emission factor was recorded, rising from 737 t CO2/t clinker in 2024 to 786 t CO2/t clinker in 2025, due to lower consumption of alternative fuels caused by instabilities in the production process. Despite this, the emission of 90,625 tons of fossil-derived CO2 into the atmosphere has been avoided.

Throughout the year, we have been working on key projects aimed at optimizing processes and increasing the use of alternative fuels, the effects of which are expected to result in a reduction in the CO2 emission ratio starting in 2026. Key initiatives include:

• improvements to the waste storage and dosing facilities for Recovery .
• The installation and commissioning of a new cooler in furnace 5E in November, which will contribute to greater process efficiency and stability. 
• construction of a synthetic gas production plant, scheduled to begin operations in May 2026, which will help increase the use of alternative fuels. 
• monitoring the process of amending the Environmental Permit to increase the use of alternative fuels from 48% to 80%.

Data on channeled emissions are reported annually to the State Pollutant Emissions and Sources Register (PRTR Spain), expressed as pollutant load and publicly available at www.prtr-es.es.

Diffuse emissions of particles and gases

The minimization of emissions resulting from the transfer and movement of powdery materials has been achieved by applying preventive measures such as belt fairing, road paving, suction systems at transfer points and frequent watering, among others.

To assess the environmental impact on air quality, two PM10 monitors and a continuous NO₂ analyzer are in operation in La Ràpita and Els Monjos, urban areas near the factory that are considered to be at risk of potential impact. This equipment is part of the XVPCA (Catalonia Air Pollution Monitoring and Forecasting Network), and the data is publicly available on the website of the Department of Territory and Sustainability. Data from 2025 confirm that levels remain stable compared to previous years and within the reference values established in Royal Decree 102/2011, regarding the improvement of air quality.

In addition, a test for settleable particles is conducted at the quarry every three years. The most recent test was conducted in 2025, and the results at all sampling points were below the reference value.

It should be noted that air quality in a given area depends on its nature, urban or rural, and is influenced by multiple external factors such as traffic, industrial activity and meteorological conditions (rainfall, wind, atmospheric stability).

In April 2025, a highly reputable company conducted a new study to monitor pollutants in the vicinity of the plant, continuing the monitoring campaigns that began in 2000 with the aim of assessing the long-term trends in levels of metals, dioxins, and furans in soil, air, and vegetation.

The results confirm levels below the limits established by Catalan and European legislation, with values comparable to those in other rural areas of Catalonia. The risk levels—both carcinogenic and non-carcinogenic—associated with exposure to metals, dioxins, and furans in the vicinity of the factory are considered acceptable in accordance with national and international standards.

Environmental management and control

As part of its environmental best practices, the Monjos plant reuses waste generated from factory dust, refractory residues, mortar and concrete test specimens, and construction debris. These materials are incorporated into the clinker manufacturing process along with limestone from quarries, thereby helping to improve Recovery rates Recovery the Monjos plant.

The organization regularly monitors trends in waste generation, analyzing the results annually to identify trends, explain possible variations, and establish improvement measures that reinforce its commitment to continuous environmental improvement. External waste management is carried out by authorized waste management companies, with whom treatment contracts are formalized, and each delivery is documented in accordance with current legislation.

The plant has a Hazardous Waste Minimization Plan, which is integrated into the environmental management system, and whose main objective is to reduce the generation of this type of waste through prevention and the efficient use of resources. Specifically, in 2025, actions were established to extend the useful life of industrial oils, conducting annual analyses to verify their condition and ensure they retain the properties necessary for use; and, when necessary, filtration treatments are performed to extend their life cycle and reduce the amount of waste generated.

In 2025, the generation of Hazardous waste Hazardous by 10% compared to the previous year, mainly due to a one-time increase in oil change operations for machinery, which led to higher generation of this type of waste. The generation of other types of Hazardous waste Hazardous stable.

As for Hazardous waste, the temporary increases in wood, general waste, and cardboard were linked to construction work on new investment projects. However, the total volume generated decreased as a result of lower rubble production following the completion of civil engineering work on the new chiller.

Biodiversity indicators

Biodiversity and restoration work

The main impact on the landscape derived from our activity is the exploitation of natural resources in our own marl and limestone quarry. For this reason, the Grupo Cementos Portland Valderrivas has defined as a future challenge the "development of integrated management criteria for the restoration of quarries and the promotion of biodiversity", a challenge that is in line with the measures established in the Environmental Authorization of the Monjos plant. 

The restoration of the quarry is carried out simultaneously with its exploitation, as part of the commitment to protect the environment. In addition, since 2007, 6 small plots of approximately 1 hectare each have been maintained in the quarry area, where cereals and leguminous plants are grown to promote biodiversity and attract local fauna such as the Bonelli's eagle that lives near the area. In July 2019, the Administration approved the new restoration program, incorporating it into Uniland exploitation no. 3,875. 

And, with a view to the future, a landscape study was presented in collaboration with a firm of architects and the municipalities of Santa Margarida i Els Monjos and Olèrdola, which contemplates the recovery of the quarry after its exploitation, integrating environmental, social, economic, urban and landscape criteria. 

Restoration evolution

By 2025, the restored area will total 45.84 hectares, representing 41.2% of the total affected area. Each year, actions are carried out in accordance with the work plan, which is consistent with the approved restoration program. 

Throughout the year, the following restoration actions have been carried out:

• work in new restoration zones: blasting to define the morphology of new restoration slopes in banks 233/213 and 351/341, and topsoil in bank 351/341.
• maintenance work in areas already restored: monitoring of plantations, phytosanitary treatments, weeding, pruning of olive trees, removal of dry pine trees, creation of a new 0.44 ha cereal plot, agricultural work in existing plots and maintenance of the amphibian pond.

Significant and/or sector specific indicators 

Sound emissions

The main impact of noise emissions in the surroundings of the manufacturing facilities is the disturbance of the population and fauna. In the case of the Monjos factory, located near the town of Santa Margarida i Els Monjos, and the quarry, near the Daltmar housing development, various measures have been implemented to minimize this impact.

At the plant, silencers have been installed at the main noise sources and buildings such as the cement and crude oil mills have been closed to minimize the propagation of noise to the nearest inhabited areas.

In the quarry, a natural mound is maintained as a noise barrier to minimize the noise generated by the crusher, especially in the direction of the Daltmar development. In addition, the advance of the quarry is strategically planned to reduce the noise emitted by the activity.

Every two years, noise measurement campaigns are conducted at representative locations around the factory and quarry to verify compliance with legal limits. The most recent official inspections, carried out by an accredited body in 2025 at the factory and in 2024 at the quarry, confirm that emission levels remain stable compared to previous years and comply with current regulations.

Vibrations

Vibrations generated by blasting in the quarry are controlled in accordance with the UNE 22381:93 standard "control of vibrations produced by blasting", taking as a reference the limits established for group II buildings (residential buildings). To minimize vibrations, the Monjos factory has been using a non-electrical initiation load sectioning system for years, which reduces the vibration velocities recorded. In addition, in blasting near the Daltmar housing development, the benches are divided into two heights, which allows for smaller and less impactful blasting. 

In 2025, the annual average of the measurements was 9.2% above the legal limit, a figure very similar to that of the previous year. The variations observed are due to the distance between the blast site and the seismograph.

Soil and groundwater protection

The activities carried out in the factory and the quarry involve the handling of potentially polluting substances, such as oils, greases, diesel, ..... The Environmental Authorization establishes specific requirements for monitoring and control of the subsoil and groundwater at different points of the facilities. The last control was carried out in 2021 and no incidents were recorded.

In response to a request from the Catalan Water Agency dated October 2025, an environmental characterization and diagnostic study was conducted in February 2026 at two locations within the factory where isolated hydrocarbon contamination had historically been detected. The study, prepared by a government-accredited monitoring entity, also included a risk analysis concluding that the health risk to potential recipients is acceptable. Additionally, a biennial groundwater quality monitoring program has been established to track changes in the quality of groundwater and the subsoil.

Description of the most important and significant environmental aspects

Identification of environmental and energy aspects

Direct environmental and energy aspects are those generated by the activities of the factory and quarry, over which there is total control of their management. These are grouped according to their environmental vector and are evaluated under normal and abnormal operating conditions. Examples of these aspects include confined and diffuse atmospheric emissions, CO2 emissions, energy consumption, exploitation of natural resources,...

Indirect environmental and energy aspects arise from activities, products and services over which there is no direct control. In particular, the following are considered: greenhouse gas emissions associated with the transportation of raw materials and fuels purchased, emissions from electricity consumption, packaging waste placed on the market after use, and the management of cement waste at the end of its useful life.

And the emergency aspects refer to the analysis of abnormal operating conditions that could cause damage to the environment. This analysis makes it possible to anticipate risks and establish appropriate preventive and response measures.

Evaluation of significant aspects

The evaluation of environmental and energy aspects is the basis for the revision of the management system, the planning of objectives and the definition of control and improvement measures.

The evaluation methodology distinguishes between different types of operating conditions:

• normal operating conditions: aspects are evaluated according to the criteria of hazardousness (understood as proximity to legal limits or internal objectives), quantity (comparing data with those of the previous year) and complaints or legal non-compliance.
• abnormal conditions: these are valued according to the quantity generated and the complaints or non-compliances recorded.
• indirect aspects: they are analyzed considering the quantity (comparing ratios with the previous year) and the capacity of influence (possibility of establishing actions for their reduction).
• aspects in emergency situations: these are evaluated according to the probability of occurrence, the severity of the impact (taking into account the resilience of the environment) and complaints or legal non-compliance.

Once the evaluation has been carried out, those aspects with a score above the established threshold are identified as significant, which allows us to focus our efforts on the most relevant impacts and guide the continuous improvement of environmental and energy performance.

This statement covers the environmental and energy aspects assessed in March 2025, based on data from 2024. As a result, electricity consumption and the consumption of additives have been identified as significant, for which targets have been set for 2025, as well as other aspects for which no targets have been established because they are considered to be adequately controlled.

No significant environmental impacts have been identified in emergency situations or as a result of indirect effects.

The table shows the degree to which the objectives set out in the Environmental and Energy Program for 2025 have been achieved.

Compliance has been monitored on a regular basis through meetings of the factory’s Environmental Committee and the Environmental Committees of the Spain Operations Division at the corporate level.

ENVIRONMENTAL AND ENERGY IMPROVEMENTS

The modernization and continuous improvement of production facilities help reduce the environmental and energy impacts of the process by applying the best available techniques to prevent and minimize pollution.

Investments made in 2025 have focused on minimizing significant environmental and energy impacts by increasing Recovery and material Recovery , as well as improving energy efficiency. The main initiatives are detailed below:

• Installation of a system to add a fourth component to cement mills: increased Recovery and a reduced carbon footprint for the final product.
• Installation and commissioning of the 5E furnace cooler and construction work on an alternative fuel gasification plant: increased Recovery and reduced CO2 emissions from fossil fuels.
• Installation of variable frequency drives on the fans of the coal mill and the M3G separator: optimization of electricity consumption.
• Improvements to the alternative fuel storage and dispensing system: increased Recovery and reduced CO2 emissions from fossil fuels.
• Purchase of a new wheel loader: reduced emissions and energy consumption associated with transportation, as it is a new vehicle.

In addition to these major investments, a number of smaller-scale environmental and energy-efficiency improvements have also been implemented, helping to reduce the impacts associated with the operation. These include the replacement of motors with IE3-class models, the conversion to LED lighting, the replacement of air conditioning units, and the restoration of 0.99 hectares of the quarry.

List of permits, authorizations and declarations in force
