A rich methane gas called biogas is made when bacteria decompose an organic substance. In addition, it’s also made from food waste, green waste, plant materials, sewage, food processing, agricultural waste, and other organic materials.
Moreover, biogas may even be extracted from places where damped organic materials are actively decomposing anaerobically, such as landfills or municipal dumpsites.
Because of this, biogas is indeed a flexible energy source. It will be cleaned or filtered to meet natural gas standards and utilized the same way as other gasses. In this case, biogas can be used for:
- transportation fuels
- specifically designed engines that turn biogas into energy that’s used for transmission systems
Moreover, the rich in nutrients sludge (called digestate) that stays after anaerobic digestion is an essential biofertilizer. In fact, it supports further reduction in greenhouse gas emissions and food production by minimizing our dependence on manufactured fertilizers.
These alternatives can indeed benefit Australia’s agricultural and environmental wellness if and only if they will be acknowledged and effectively implemented.
