Biogas, Biofuel & CHP

ARK makes biofuel and installs CHP systems practical for operations of almost any size — not just large industrial plants.

Compact biogas systems can start with as little as 5 gallons of organic waste per day and a small warm space. Here is the economics:

How the System Works

Organic inputs — fish waste, crop residues, food scraps — are collected and fed into an anaerobic digester.

Microorganisms break down organic matter in the absence of oxygen, producing biogas (primarily methane and CO₂) and digestate.

Biogas is captured, filtered, and conditioned to remove moisture and impurities before use in the CHP unit or boiler.

The CHP engine burns biogas to generate electricity for the facility and recovers exhaust heat for greenhouse climate control.

Nutrient-rich digestate is processed and returned to the growing system as a natural fertilizer, completing the closed loop.
