Sustainable resource recovery and innovation

Effective recovery, recycling, and re-use of materials can significantly reduce environmental impact, lower carbon emissions, and unlock economic value from waste and side-streams. CPI helps you develop and implement innovative processes to extract, recover, and repurpose a wide range of materials — including metals, plastics, and ceramics.

We support you from concept to commercialisation, offering pilot-scale demonstration and detailed life cycle and techno-economic assessments. By combining expertise in chemistry, engineering, and sustainability, we deliver scalable, efficient, and commercially viable recovery and recycling solutions.

Stuff4Life

"We are really excited about the next stage of our Stuff4Life journey. Our ultimate goal remains the same – to make new polyester products from old polyester products – but also to make the next generation of workwear last even longer, perform even better and be more recyclable when its job is done. This can make a real difference delivering not just a circular economy for critical materials but decarbonising industrial processes and delivering even better outcomes for all."

Descycle

The future for DEScycle is really exciting. DES truly has the potential to change the world, delivering a step-change in how we produce and recycle metals. By replacing energy and emission intensive processes with DEScycle’s novel technology we can supply the energy transition with low-impact low-carbon metal. Thanks to CPI’s investment and in-house experience, we will be able to rapidly commercialise this technology and bring real disruption to the metals market.
