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.

Our Solution: Single-Source Responsibility

We bridge the gap between process engineering and construction. Whether you need a full Turnkey (EPC) solution or a core technology package, we ensure the entire system—from feedstock intake to gas grid injection—operates as a unified, high-efficiency asset.

Proprietary Digestion Technology
We Design The Process (The Brain)

Proprietary Digestion Technology

We don't just build tanks; we design the biology. Our CSTR/High-Rate anaerobic systems are tailored to your feedstock (Typical OLR: 5-8 kgCOD/m³·d) for maximum gas yield.

Integrated System Manufacturing
We Manufacture The Core (The Heart)

Integrated System Manufacturing

We manufacture critical systems in-house: digesters, gas holders, purification skids, and CHP islands. This ensures perfect compatibility and quality control before the equipment even reaches the site.

Project Execution & Commissioning
We Execute The Project (The Muscle)

Project Execution & Commissioning

Our project management team directs site operations and commissioning. We take single-source responsibility for the plant's final performance, ensuring a smooth ramp-up to full capacity.

Flexible Engagement Models
