Biogas leading the green future
Sustainability is here, and it’s staying
When we process food waste, animal farm waste and organic wastewater through anaerobic digestion, green biogas is produced which contains between 60% – 65% of Methane. The biogas produced will undergo an upgrading process which will upgrade the biogas to biomethane (>92% methane content). Biomethane has the same molecular composition as natural gas, and is able to be injected directly into the national gas rid such as the Peninsular Gas Utilisation (“PGU”) pipeline network in Malaysia.
A by-product of the anaerobic digestion process is that the digestate produced is considered as organic fertilizer which contains high amounts of carbon, nitrogen, phosphorus and potassium, which are major nutrients to plants while at the same time help reduce environmental impact of organic waste materials.
Production of biogas
Malaysia as an agriculture-heavy economy produces a lot of organic waste through food waste from Municipal Solid Waste and animal farm waste from chicken, pig, cow farms. More than 17,000 tonnes of food waste are disposed by Malaysians every day.
Our processes involves mixing food waste, animal waste such as chicken dung and organic wastewater in anaerobic digesters. The bacteria and microorganisms will break down the organics in an oxygen-absent environment and subsequently produce biogas. The biogas produced will contain other elements such as carbon dioxide, hydrogen sulfide, nitrogen, water vapor, ammonia, and other trace gases which have to be removed through a process called “upgrading”.
Once the biogas is upgraded to biomethane, then it will be able to be injected to the national gas grid.
Greener fertilizer for the farmers
One of the problems we are trying to solve is caused by the usage of raw chicken dung as fertilizer for the agriculture industry. The usage of raw chicken dung promotes the spread of pathogens which contributes to the severe infestation of flies, and environmental contamination. The organic fertilizer produced from our anaerobic digestion process is nutrient-rich, lower odor and contaminants, and has a lower carbon footprint.
