AGC PreCast Solutions has released its 2025 Sustainability Report, outlining measurable progress in reducing the environmental impact of concrete production while maintaining structural performance and product durability. The report shows a 22 percent reduction in embodied carbon per tonne of finished precast element compared with the company's 2023 baseline.
Key Drivers of Reduction
The improvement was achieved primarily through greater use of supplementary cementitious materials, mix optimisation across standard product ranges, and closer control of batching accuracy. Cement remains the largest contributor to concrete-related emissions, so reducing clinker demand without compromising strength development was a major focus for the technical team.
Additional gains came from better curing efficiency, more disciplined aggregate moisture correction, and reduced material waste during mould preparation and demoulding. The company also expanded internal monitoring of rejected units, helping operations teams identify repeat causes of waste and address them at source.
Looking Ahead
AGC PreCast is now evaluating low-carbon reinforcement strategies, transport route optimisation, and supplier partnerships that support more transparent environmental reporting. These next steps are expected to improve both procurement decisions and client-facing carbon disclosure for major projects.
The company views sustainability as an engineering and operational discipline rather than a separate communications exercise. For clients, that means lower-carbon precast solutions backed by documented process improvements, verified data, and the same quality standards expected on structural work.
