Our Technology

Converting waste to energy through advanced biogas systems

Bio-CNG Production Process

Our technology efficiently converts organic waste into clean, compressed natural gas through a sophisticated biological process. We use specially designed anaerobic digesters to break down Napier grass and animal dung in an oxygen-free environment, allowing naturally occurring bacteria to convert the organic matter into biogas.

This biogas, primarily composed of methane and carbon dioxide, undergoes a rigorous purification process to remove hydrogen sulfide, carbon dioxide, and moisture. The resulting high-methane gas is then compressed to 200-250 bar pressure to create bio-CNG, which has properties similar to conventional natural gas and can be used in natural gas vehicles and industrial applications.

Our technology represents a significant advancement in renewable energy production, with efficiency rates exceeding 75% and minimal environmental impact. The system is designed to be scalable, allowing for implementation in various settings from rural communities to larger industrial operations.

Bio-CNG Production Process

Our Production Process

A step-by-step look at how we convert organic waste into clean, usable bio-CNG

Napier Cultivation

Grow high-yield Napier grass using organic fertilizer at our farms

Waste Collection

Collect agricultural residues and livestock manure for digester use

Feedstock Prep

Shred and mix Napier grass with animal waste to create feedstock

Anaerobic Digestion

Break down organic matter in sealed digesters to produce raw biogas

Biogas Scrubbing

Purify biogas by removing CO₂ and H₂S to achieve 95% methane purity

Bio-CNG Production

Compress purified biogas into bio-CNG for storage and transport use

Fuel Distribution

Distribute bio-CNG to industries/vehicles as clean fuel alternative

Digestate Processing

Process nutrient-rich digestate into organic fertilizer pellets for farms

Fertilizer Sales

Supply organic fertilizer to farmers to boost crop and Napier yields

Soil Enrichment

Reapply fertilizer to farmland, completing cycle for new Napier growth

Our Napier-CNG Advantage

Specialized technology for maximum yield from Napier grass biomass

Optimized Napier Processing

Specialized shredders and pre-treatment systems designed specifically for high-fiber Napier grass, achieving 30% faster digestion rates.

Napier-Adapted Digestion

Proprietary microbial blends optimized for Napier grass cellulose breakdown, achieving 85% volatile solids conversion efficiency.

Tropical Climate Optimized

Temperature-controlled digesters maintaining ideal 37°C for Napier decomposition even in external 45°C ambient conditions.

Closed-Loop Water System

Valuable Byproducts

Our process creates additional value streams beyond bio-CNG

Organic Fertilizer

The digestate byproduct from our biogas plants is rich in nitrogen, phosphorus, and potassium. After proper processing, it becomes an excellent organic fertilizer that:

  • Improves soil structure and water retention capacity
  • Provides slow-release nutrients for plants
  • Reduces dependency on chemical fertilizers
  • Creates an additional revenue stream for the plant

We process approximately 8-10 tons of organic fertilizer from every 100 tons of feedstock, completing the circular economy model of our operations.
