The only leftover material from the solid waste, the carbon mass from the Pyrolysis reactor undergoes the following stages
Carbon mass is mixed with Binder
Mixture subjected to high temp & pressure comes out as pellets through specially designed Dies
Cooling of pellets to room temp
Screening to get the uniform output of carbon pellets
Packaging & storage

Carbon Pellets have @ 7000 Kcal of heat output and hence find use as a FUEL for burning/heating applications
