Frequently Asked Questions

Clear answers regarding organic waste biomethanation and Bio-CNG projects.

Pressmud (sugar mill waste), agricultural paddy straw, cattle dung, municipal organic solid waste, food processing sludge, and distillery spent wash are ideal high-yield substrates.
Under government SATAT price guarantees and organic fertilizer (FOM) commercial sales, commercial Bio-CNG plants typically achieve full capital payback within 3.5 to 5 years.
