Estimate methane production and energy value from anaerobic digestion of agricultural, food, and brewery waste streams.
Organic waste contains significant energy. Anaerobic digestion converts volatile solids into biogas — a renewable fuel that displaces purchased energy and reduces disposal requirements.

This tool estimates the biogas and methane an anaerobic digester can produce from a given feedstock, flow and organic load — a useful first check on whether energy recovery is worth pursuing and how large a plant might be. Yield depends strongly on the feedstock’s biodegradability, the organic loading rate, retention time and temperature, so the figures here are an indicative screening estimate rather than a design. For a real project we follow this with biochemical methane potential testing and a full mass-and-energy balance, because feedstock variability and inhibition effects can move the result significantly. Used in that spirit, the estimate helps frame the opportunity before detailed design begins.
