Sustainable Solutions for Industrial Biogas & Biomethane Plant 

Biowatt-Biogas® provides high-efficiency Waste-to-Energy (WTE) systems and end-to-end EPC services. We help agriculture and industry reach Net-Zero by converting organic residues into renewable electricity, heat, and high-value Biomethane (RNG).


From Waste to High-Value Energy: Biomethane & Beyond
Beyond electricity generation, Biowatt-Biogas® provides advanced Biogas Upgrading to convert raw biogas into high-purity Biomethane (RNG), meeting international standards for CNG fueling and LNG distribution.
Methane Capture: Turning harmful emissions into reliable fuel.
Grid-Ready Commodity: High-purity RNG for grid injection or industrial use.
Lower Emissions: Replacing fossil fuels with carbon-neutral alternatives.
Bio-fertilizer Production: Utilizing digestate to restore soil health.


By balancing environmental stewardship with economic viability, Biowatt-Biogas® helps global partners achieve ESG (Environmental, Social, and Governance) goals while driving profitable, green growth.
