BRIN Develops Simple Technology to Convert Landfill Methane into Fuel and Electricity

Landfills hold untapped energy potential that has long been wasted. The National Research and Innovation Agency (BRIN) has developed a technology to harvest methane gas from landfills for use as cooking fuel and electricity generation for local communities.

Principal Researcher Sri Wahyono explained that the technology is designed to be simple and easy to implement across various regions, using readily available components such as pipes, suction blowers, and gas purification units.

“This technology utilises simple equipment like pipes, suction blowers, and gas purification units. The collected methane gas can be used as cooking fuel or as an energy source for modified generators to produce electricity from landfill methane,” Sri said on Monday (25 May).

The development is based on field experience and collaboration with landfill operators in several regions, including Malang.

The process begins with field studies to identify waste pile characteristics and methane content, followed by software analysis to predict gas potential and determine optimal well placement.

Gas wells are installed horizontally or vertically, spaced according to the waste pile conditions. Methane is drawn through pipelines using suction blowers due to its low pressure. Before use, the gas is purified to reduce water, carbon dioxide, and hydrogen sulfide content for safer consumption.

Currently, harvested methane is used for local community cooking needs and internal landfill operations. It can also power small-scale electricity generation, though supply stability remains a challenge to address.

“This technology is simple but has proven effective in several landfills, benefiting nearby communities,” Sri added.
