Through ADOS (Anaerobic Digestion for Organic Solids) technology, Greeneple provides circular renewable energy that helps combat climate change.

ADOS

Greeneple owns proprietary ADOS technology, producing higher yield of CH₄ with zero odor & zero wastewater.

Anaerobic Digestion of Organic Solids (ADOS)

ADOS is Greeneple's breakthrough dry anaerobic digestion technology that transforms high-solid organics into renewable natural gas through an optimized percolation-based process. ADOS can operate with 10-90% organic solids and completes the biogas production cycle in 20 days. This compact, modular system eliminates odor emissions and wastewater generation while delivering superior methane yields, making it ideal for distributed energy applications and community-scale renewable energy projects.
