what are the advantage and disadvantages of biogas.
Answers
Answer:
Advantages of Biogas
1.Renewable Source of Energy
Organic materials are derived from plants, animals, and humans. Raw materials can be reproduced, making biogas a green energy source. It also lessens the damaging impact and improper wastes disposal.
2.Utilization of Waste
Instead of letting the wastes rot in landfills, it is more advantageous to utilize and turn them into biogas. An environmental hazard is reduced due to lesser methane, carbon dioxide, and other greenhouse gases produced. Wastes are turned into energy to utilize for electricity, heating, cooking, and as fertilizers.
3.Produces a Circular Economy
Animal manure, food wastes, wastewater, and crop residue are wastes produced by humans and animals. These wastes can cause harm if not process correctly. By turning these organic wastes into biogas, the wastes are converted into a more helpful way. The wastes are made into biogas for electricity and heating use, natural gas for cars and cooking, and digestate as fertilizers.
4.A Good Alternative for Electricity and Cooking in Rural Areas and Developing Countries
Some areas have limited access to electricity, hampering their way of living. Biogas can provide them a good alternative. It is economical to set up and possible both for small- and large-scale production.
Disadvantages of Biogas
1.Few Technological Advancements
The biogas industry is not yet advanced. Additional research is needed to develop new technology and make production efficient. Also, governments provide more support on established energy sources such as solar, geothermal, wind, and hydropower.
2.Weather Dependence
Like other intermittent energy sources (solar, wind), biogas production is also affected by the weather. Anaerobic digestion happens in an environment with a temperature of 37°C. Heat energy is required in cold climates to produce biogas continually.
3.Foul Odor Emitted from Biogas Power Plant
Biogas plant emits foul odor from the wastes they process. Power plants should be built in a location away from residences and other industrial areas.
