Kalinga Restoration Project
Turning rice husk into durable carbon removal for Indian agriculture.
Rice husk is an abundant agricultural residue in Odisha.
We convert it into stable biochar for permanent soil carbon storage.
The Kalinga Restoration Project converts rice husk, an abundant agricultural residue in Odisha, into biochar through controlled pyrolysis. The biochar is then incorporated into agricultural soils, where its stable carbon is designed for long-term storage while supporting soil health and agricultural productivity.
LongStraw maintains comprehensive technical diligence packages for carbon removal procurement desks, institutional investors, and independent diligence rating agencies.
