Process Engineering

From Waste to Renewable Energy

Six integrated stages that transform organic waste into clean biomethane, energy, and bio-fertilizer — with zero waste to landfill.

Step 01

Feedstock Reception & Pre-Treatment

Organic waste streams are received, characterized, and pre-processed. Solid-liquid separation, size reduction, and contaminant removal prepare the feedstock for optimal digestion.

Livestock Waste Crop Residues Food Waste Industrial Effluent

Step 02

Mixing & Conditioning

Feedstocks are blended to achieve optimal C:N ratios and total solids content. Temperature conditioning ensures ideal micro-biological activity before entering the digester.

C:N Optimization pH Balancing Thermal Conditioning

Step 03

Anaerobic Digestion

Core biological conversion in sealed mesophilic (37 °C) or thermophilic (55 °C) reactors. Microorganisms break down organics over 20–30 days, producing raw biogas and nutrient-rich digestate.

CSTR Reactor UASB Systems 37–55 °C 20–30 day HRT

Step 04

Biogas Capture & Upgrading

Raw biogas is captured from sealed reactor covers and passed through H₂S removal and dehumidification, then upgraded via membrane separation or PSA to achieve 97%+ biomethane purity.

H₂S Scrubbing Membrane Separation PSA Upgrading 97%+ CH₄

Step 05

Energy Dispatch

Purified biomethane is routed to CHP engines for combined heat & power, compressed to Bio-CNG for vehicle and industrial fuel, or injected directly into the national gas grid.

CHP Generation Bio-CNG Grid Injection

Step 06

Digestate & Resource Recovery

Nutrient-rich digestate is separated into liquid and solid fractions. Liquid bio-fertilizer is applied directly to farmland; solid fractions are composted — completing the circular loop with zero waste.
