Biogas Production Calculator

BMP is the maximum amount of methane that can be produced from a specific organic material under anaerobic conditions. It's measured in cubic meters of methane per ton of volatile solids (m³ CH4/ton VS).

Total solids represent the dry matter content of feedstock, while volatile solids are the organic portion that can be digested. Higher VS content generally means more biogas potential, but the optimal TS content varies by feedstock type.

Energy crops like corn silage typically have the highest biogas yield, followed by food waste and animal manure. The actual production depends on the specific composition, freshness, and processing of the material.

Modern biogas plants typically achieve 35-45% electrical efficiency when converting methane to electricity. Combined heat and power (CHP) systems can reach overall efficiencies of 80-90% when both electricity and heat are utilized.

Key factors include feedstock availability and cost, local electricity and heat prices, government incentives, plant size and efficiency, and the ability to utilize both electricity and heat output.

Generally, a minimum of 10,000-30,000 tons per year of organic feedstock is needed for commercial viability, though smaller plants can work for specific applications or with high-value feedstocks.

Biogas production reduces greenhouse gas emissions by capturing methane that would otherwise be released, provides renewable energy, and creates digestate that can be used as organic fertilizer.

The retention time in a biogas digester typically ranges from 20-40 days depending on temperature, feedstock type, and desired gas production efficiency. Thermophilic processes (50-60°C) are faster than mesophilic (35-40°C).
