Biogas Installation & Waste-to-Energy
Turn farm and kitchen waste into unlimited free cooking gas.
Biogas technology converts animal manure, agricultural crop residues, and kitchen organic waste into clean, pressurized methane gas for cooking and lighting, while yielding nutrient-rich organic bio-slurry fertilizer. IES designs and builds fixed-dome and pre-fabricated tubular digesters for households, dairy farms, and institutions across Malawi.

Execution & Methodology
What to expect when you work with IES
From initial site audit to ongoing servicing, here is how our renewable energy professionals coordinate every phase of your biogas installation & waste-to-energy installation.
Feedstock & Waste Audit
Evaluation of available daily organic feedstock (cattle dung, pig waste, food scraps) and water volume to precisely determine digester cubic capacity.
Masonry & Digester Construction
High-durability brickwork, gas-tight plastering, inlet mixing chamber construction, and overflow bio-slurry collection pits.
Gas Piping & Safety System
Installation of UV-resistant gas piping, pressure relief safety valves, water drain traps, and specialized biogas burners.
Bio-Slurry Fertilizer Utilization
Instruction on harvesting and applying enriched organic bio-slurry to crops, eliminating the need for expensive chemical fertilizers.
