1. Make a list of substrates that are typically used for biogas plant.
a. Agricultural wastes: This includes various agricultural by-products such as crop
residues, animal manure, and spoiled hay or silage.
b. Food waste: This includes food waste generated by households, supermarkets,
and food processing industries.
c. Industrial waste: This includes waste generated by various industrial processes
such as paper mills, breweries, and distilleries.
d. Sewage sludge: This is the solid residue generated during the treatment of
wastewater.
e. Energy crops: This includes crops that are grown specifically for energy
production, such as corn, sugarcane, and switchgrass.
f. Landfill gas: This is the gas that is generated by the anaerobic decomposition of
organic waste in landfills.
g. Forest residues: This includes various types of wood waste, such as logging
residues, sawdust, and wood chips.
h. Green waste: This includes grass clippings, leaves, and other yard waste.
i. Aquatic biomass: This includes various types of aquatic plants, such as algae
and seaweed.
j. Organic fraction of municipal solid waste (OFMSW): This is the organic
fraction of the waste generated by households and commercial establishments.
2. Choose 1 substrate among all the listed materials and make 1 page write up on the
potentials of this substrate for biogas production.
Biogas creation is a practical and sustainable power creation process that involves
natural waste as a substrate. A common substrate for the production of biogas is agricultural
waste. Various agricultural processes produce waste, including crop residues, animal manure,
and spoiled hay or silage.
The abundant availability of agricultural waste as a substrate is one significant
advantage. Farming waste is created in huge amounts universally, making it a promptly
accessible substrate for biogas creation. Besides, rural waste has a high energy content because
of its high natural matter substance, making it a phenomenal substrate for biogas creation.
The low cost of producing biogas from agricultural waste is yet another significant
advantage. Since agricultural waste is typically available at a low cost or even free, it is an
affordable substrate for the production of biogas.
Moreover, biogas creation from rural waste outcomes in the development of supplement
rich digestate, which can be utilized as a compost in farming. Utilizing agricultural waste as a
substrate has this added advantage.
Finally, by utilizing methane, a potent greenhouse gas, as a fuel, the utilization of
agricultural waste as a substrate for the production of biogas contributes to the reduction of
emissions of greenhouse gases.
In conclusion, the abundant availability, high energy content, low cost, nutrient-rich
digestate, and reduction in greenhouse gas emissions make agricultural waste a valuable
substrate for biogas production. The utilization of horticultural waste as a substrate for biogas
creation can assume a critical part in accomplishing supportable and environmentally friendly
power creation, adding to the worldwide exertion towards a cleaner and more practical future.
