Sewage treatment doesn’t just clean water, it produces a steady stream of sludge that, left untreated, becomes an environmental challenge. At Enviro, we view this by-product as an opportunity.
Through our Waste-to-Energy (WTE) package solutions, we design, build, operate, and maintain systems that convert sewage sludge into renewable energy. Using biogas from anaerobic digestion, our plants generate electricity and heat that can power treatment facilities themselves, reducing operating costs, lowering carbon emissions, and advancing the circular economy.
Primary and secondary sludge fed into digesters. Mixing options: hydraulic pumping, jet mixing, mechanical mixing, gas mixing, or hybrid systems. Temperature-controlled for mesophilic (35–38°C) or thermophilic (50–55°C) operation.
Removal of hydrogen sulfide and impurities through chemical, bio-chemical, or biological scrubbers. Moisture removed using dehumidifiers.
Purified gas stored in double-membrane gas holders sized for production and consumption balance.
Electricity generation via biogas engines. Combined Heat and Power (CHP) options, recovered heat used for sludge drying, building heating, or process needs. Potential for biogas upgrading and grid injection.
Tailored dewatering with centrifuges, screw presses, or drying systems. Digestate repurposed as fertilizer or safely disposed.

Sludge-to-Energy
We engineer advanced digestion systems specifically optimized for both municipal and industrial sludge profiles.
Our systems utilize high-efficiency Combined Heat and Power (CHP) units ranging from 250 kWe to over 1 MWe. These engines are precision-tuned to convert biogas into simultaneous electrical and thermal energy, achieving total system efficiencies far exceeding conventional power generation.
We integrate energy-efficient handling systems designed to streamline the movement and processing of organic residuals.
Our “Smart-Plant” integration utilizes AI-driven monitoring to analyze real-time biological and operational data; we then optimize the digestion process for maximum stability and peak energy ROI.
Our scrubbing systems ensure clean, safe, and compliant energy production, reducing emissions, protecting communities, and supporting the transition to sustainable energy.
Maximum Energy ROI: Strategic transformation of waste liabilities into power assets, eliminating disposal fees and shielding facility OpEx from utility price volatility.
