C-Green has been selected by CMPC, one of the world's largest pulp and paper companies, and Foresight Canada, Canada's cleantech accelerator, as winner of the Pulp Mill Sludge Efficiency Challenge, a competition seeking innovative solutions to handling wastewater sludge.

CMPC, with 47 plants in eight countries, chose C-Green as one of two winners after a review of applicants from five countries. The winners will have the possibility of developing a pilot project with CMPC.

C-Green's OxyPower HTC combines two established technologies: hydrothermal carbonization (HTC) and wet oxidation, creating an ideal solution for wet biowaste handling. The process operates in an energy efficient manner, simplifies nitrogen and phosphorous recovery, and produces a multi-purpose hydro-char that can be used as a biofuel. The process is self-sustaining, creating all of the heat energy required by the HTC process through an innovative application of wet oxidation.

"Biosludge from industry and municipalities is a huge environmental burden in terms of GHGs, loss of nutrients, and transportation of large amounts of water. These problems are eliminated with our OxyPower HTC process. This Challenge presented an innovative and convenient opportunity to work with one of the world's largest pulp and paper companies. In this industry, our technology can solve the sludge and bio ash challenges to transform environmental problems into fertilizer," says Peter Axegård, Senior advisor, C-Green.

C-Green is a Swedish clean-tech company with a technology that transforms wet waste into useful products in a cost-efficient and climate smart way.
