PHOMI has published its 2025 annual sustainability report, documenting progress across carbon emissions, raw material sourcing, water consumption, and supply chain transparency. The headline figure — a 35% reduction in CO₂ per tonne of product manufactured compared to the 2020 baseline — reflects both process improvements and the increased proportion of econiclay formulations in the product mix.
Key figures from the 2025 report
- Carbon intensity per tonne manufactured: reduced 35% versus 2020 baseline
- Proportion of raw materials derived from solid waste streams: 78% (up from 61% in 2022)
- Energy consumption per tonne: reduced 28% through low-temperature process optimisation
- Water recycling rate in manufacturing: 94%
- Zero landfill waste policy: achieved across all production facilities
What drove the improvement
The largest single contributor to carbon reduction was the optimisation of the econiclay activation process to reduce required processing temperatures. Early econiclay formulations required sustained heat application; current formulations achieve full activation at temperatures 22% lower, reducing the energy draw from manufacturing equipment.
The second major factor was the increased proportion of construction waste, mining tailings, and fly ash in the raw material mix. These materials are gathered from industrial waste streams and would otherwise require energy-intensive landfill management.
Third-party verification
The 2025 sustainability data was verified by Bureau Veritas against the GHG Protocol Corporate Accounting and Reporting Standard. Lifecycle assessment data for individual product lines was conducted in accordance with ISO 14040/14044 and is available in the technical library for specifiers seeking to incorporate PHOMI products into LEED, BREEAM, or EDGE-certified projects.
