Responsible Water Stewardship Reducing Our Operational Environmental Footprint At VCON, we are committed to reducing our environmental impact by minimizing water usage and protecting biodiversity and ecosystems. Clean, accessible water is essential not only for human health but also for building a sustainable future. However, water resources are increasingly under threat due to unsustainable management practices and climate change.

This issue is especially important to VCON, as our precast concrete production process consumes a significant amount of water at every stage of its lifecycle. Preparing for a future of potential water scarcity is critical to our long-term success and our positive impact on surrounding communities.

VCON is committed to reducing freshwater consumption by an average

25% Reduction BY 2030

of 5% per year across all operations, starting from our 2022 baseline. By 2030, our goal is to achieve a cumulative 25% reduction in water use and maintain a water recycling rate of

Development Goal 6 (Clean Water and

RECYCLING

This target aligns with UN Sustainable Sanitation) and reflects our commitment to sustainable manufacturing and resource efficiency.

22

Strategic Monitoring and Pilot Programs Beyond factory operations, our approach includes testing and piloting water and waste reduction strategies across VCON offices and staff residences. We are actively identifying opportunities to convert wastewater into clean water. Recently, we installed water meters on job sites to measure and monitor consumption, which represents our first step toward establishing a data baseline and evaluating future water conservation strategies.

Our Water Recycling System To address this challenge, we have implemented a closed-loop water recycling system at our production facilities. This system captures wastewater generated from our manufacturing processes and treats it through sedimentation, filtration, and purification. The result is clean, reusable water that is reintegrated into our operations for concrete mixing, equipment washing, and dust suppression dramatically reducing our reliance on freshwater and minimizing environmental discharge.

This initiative reflects our commitment to circular economy principles and sustainable factory operations.

23

Performance and Impact Since the launch of our recycling system, VCON has reduced its annual water usage by 3–5%, based on a baseline of 6,340,128 US gallons per year. Over the past three years, this has resulted in an estimated total savings of over 760,000 US gallons.

These results demonstrate measurable, ongoing progress in water efficiency and sustainability.

This figure represents the average annual water consumption across VCON’s four factories, based on operations running at approximately 80% production capacity and reflecting reductions achieved through our closed-loop recycling systems.

24

Looking Ahead While carbon emissions have historically been the central environmental focus in the construction industry, we recognize that water use, recycling, and biodiversity are equally critical. At VCON, we are proactively expanding our environmental strategy to address these interrelated challenges and drive meaningful change across the industry.
