Biogas is a gaseous renewable energy source [1] produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester , biodigester or a bioreactor .
Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2]
The production of biofuels can be very energy intensive, which, if generated from non-renewable sources, can heavily mitigate the benefits gained through biofuel use. A solution proposed to solve this issue is to supply biofuel production facilities with excess nuclear energy, which can supplement the power provided by fossil fuels. [111]
The Jatropha curcas species appears to be a particularly suitable source of biofuel as it already grows commonly in Cambodia. Local sustainable production of biofuel in Cambodia, based on the Jatropha or other sources, offers good potential benefits for the investors, the economy, rural communities and the environment. [53]
Renewable natural gas or biogas is a methane-based gas with similar properties to natural gas that can be used as transportation fuel. Present sources of biogas are mainly landfills , sewage , and animal/ agri-waste .
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]
The owners of two North American renewable natural gas (RNG) producers have put them up for sale, after new U.S. tax incentives and recent big investments in the sector gave hope they can cash out ...
