C-Green is an innovative process engineering company with a complete solution to efficiently convert large amounts of sludge into biocoal. The process is based on hydrothermal carbonization (HTC), which copies nature’s way of breaking down complex organic compounds into coal but takes a few hours instead of millions of years.
Envigas delivers thermochemical processes to turn organic residuals into value. Any organic material can be used to produce BioCarbon, BioOil and Syngas. Wood, bark or sawdust from the forests, stalks, husks or straw from the agro-sector or even slurries such as manure or waste water sludge can be turned into value using our processes.
