One of the advantages of biomass is the fact that it is renewable. It is highly efficient, and the reason that oil is . 1. It may also encourage monocultures of crops, which decreases biodiversity and strips soils of nutrients, making areas more susceptible to erosion. 3. However, rather than using heat, in this process bacteria turn the organic material into biogas, a type of biofuel that is made up of methane, carbon dioxide, and small amounts of other gasses. One of the most serious disadvantages of fossil fuels is mercury emission. We can burn solid biomass to produce heat directly. Answer: Besides carbon dioxide and monoxide emissions, burning biomass in solid, liquid, or gaseous states can emit other hazardous pollutants and particulate matter into the air, including volatile organic compounds and nitrogen oxides. Some biomass plants rely on algae, which tend to require large amounts of phosphorus fertilizers to produce the amounts needed for energy production. Mercury is extremely toxic and significantly damaging to the environment. In order to use biomass as a fuel, it needs to be converted into energy. Then we have all of the trash and waste that gets produced by human activities in each country. Geothermal and nuclear energy are the only energy resources that do not come from the Sun. Thats why the emphasis is on garbage, manure, and dead plants. Common energy crops such as corn, beets, and sugar cane need to be irrigated with large amounts of water when grown on an industrial scale. It doesn't create any additional carbon because it's already been through the natural process of photosynthesis, meaning it's already done its job of absorbing CO2. The heat produces steam to power electricity generators. Other renewable sources are carbon-zero, which is much better when looking to tackle climate change. Carbon Neutral. Biomass energy plants need quite a bit of space, mainly because of needing storage space. 13. Being more affordable than fossil fuels gives biomass the edge.
