Puraffinity Ltd

Puraffinity is a London-based company founded by Henrik Hagemann, Ben Reeve, and Gabriella Santosa in June of 2015. The company developed and deployed a custom granular media (CGM) method for removing pollutants from contaminated water and wastewater supplies. The CGM is capable of removing micropollutants that include pesticides, pharmaceuticals, and high-performance chemicals.

Purrafinity is a green technology company that designs smart materials for environmental applications, with cutting-edge material design coupled with creative engineering, addressing the global market PFAS treatment requirements.

CustoMem was founded in 2015 by a team including Henrik Hagemann and Gabi Santosa and is located in London, United Kingdom. The company engineers microbial cellulose, also referred to as microbial nanocellulose, for water purification applications.

After originally pursuing sheet materials, CustoMem is now developing granular cellulose products to selectively capture and adsorb pollutants including pesticides, pharmaceuticals, and other chemicals present in wastewater streams. The CustoMem Granular Media (CGM) will compete in the market with ion-exchange resins and Granular Activated Carbon (GAC).

The company's headquarters are located on Imperial College London's White City Campus, which brings together researchers, business leaders, and industry partners to commercialize novel technologies.

The company originated from Imperial College London's 2014 iGEM Competition team project, Aqualose, which won a Gold Medal in that year's manufacturing track. The team finished second overall out of 245 teams.
