Biogas is a renewable fuel produced when organic matter, such as food or animal
waste, is broken down by microorganisms without oxygen. This process is called
anaerobic digestion. Additionally, this process also produces an organic, nutrient-rich
liquid fertilizer.
Biogas is ideal for farms and restaurants that produce more organic waste and
need larger amounts of biofertilizer.
Important
Information
Costs:
The cost of buying and installing a kitchen waste biogas plant varies depending on
the size and
quality of the system, ranging from several hundred dollars to over $6,000.
The kitchen waste biogas plant price (for small families that produce reduced
waste):
about $1,000.
Backyard biogas plant price (for large families): $ 2,000+
Other things that must be bought regularly in the future includes:
New filters: $30.
Gas bags: $225.
Probiotic tablets: $30.
Tax Credits
The IRA will give up to 30 percent tax credits to biogas facilities built by the
beginning of 2025.
Carbon offset credits: In the USA, carbon offset credits can be earned by reducing
greenhouse
gas emissions, such as methane recovered from the biogas system. These credits are
monetary
and can be bought and sold on commodity exchanges.
Carbon credits are calculated based on the amount of methane reduced by
installing
an anaerobic digester. This approach considers:
How much methane was emitted before the digester was installed?
How much methane is emitted after the digester is installed?
