Quiet Bioenergy develops next-generation additives that boost biogas production, strengthen energy independence and slash emissions.
Quiet Bioenergy develops a small molecule that accelerates microbial energy transfer inside anaerobic digesters. By improving how microbes convert organic waste into biogas, our technology significantly increases digester productivity, lowers biomethane production costs, and enables broader global deployment of renewable gas infrastructure.

Problem
Europe’s energy supply remains vulnerable due to geopolitical tensions, climate change, and heavy import dependence. The Ukraine–Russia war exposed this fragility: over 40% of EU gas once came from Russia, and the EU still imports nearly 90% of the gas it consumes. Biomethane, produced from organic waste through anaerobic digestion, offers a sustainable alternative. However, current production is slow and costly: converting waste into biomethane can take around 45 days, limiting throughput and requiring large, capital-intensive infrastructure. As a result, biogas production can cost up to three times more than fossil natural gas.


Solution
Quiet Bioenergy has developed a small molecule that accelerates microbial energy transfer inside anaerobic digesters, unlocking major efficiency gains. Our solution increases biogas yield by 20% per unit of feedstock, allows digesters to handle three times more organic material, and reduces H₂S production by a third. Fully compatible with existing facilities, our technology boosts productivity, lowers operational costs, and makes biomethane production faster, cleaner, and more scalable.
