Warana CBG Project
District of Kolhapur, Maharashtra India
In partnership with one of Maharashtra’s largest sugarcane cooperatives, Warana Sugarcane Cooperative, SREL has developed a first-of-a-kind project that converts a sugarcane waste called pressmud (filtercake) into renewable CBG and organic manure/soil conditioner. The CBG is a clean and inexpensive fuel that is being sold to industrial customers, and the nutrient-rich organic manure/soil conditioner is being sold to the cooperatives’ sugarcane farmers and in the local agricultural markets.
