Listen Biofuel – Fuel made from biomass that can be used to heat homes and power cars. Listen Air pollution - Gases and particles (like dust or smoke) in the air that can damage the environment, plants, animals and human health. Listen Carbon neutral – This is when the amount of carbon that is released into the atmosphere is the same as the amount of carbon that is absorbed from the atmosphere. Methane stays in the atmosphere for about ten years. Listen Methane - About one fifth of carbon emissions are methane gas. This can stay in the atmosphere more that one hundred years. Listen Carbon dioxide - About three quarters of carbon emissions are carbon dioxide gas. Listen Carbon emissions – The release of carbon into the earth’s atmosphere, which contributes to climate change. Listen Organic matter – The waste that comes from living plants and animals that is beginning to breakdown and decay. Listen Biomass – An important energy source which is converted from materials made from plants and animals. For example, biodiesel can be made from sugar cane and used to fuel cars instead of diesel from oil.Ī type of alcohol called ethanol can be made from corn and be can also used as biofuel for vehicles. We also convert crops into liquid biofuel. And when trees die naturally they rot away and their nutrients help keep the soil healthy so other plants can grow. Trees that are left to grow longer keep absorbing carbon. Trees provide a home for wildlife that is lost if they are removed. We also need to think about what cutting down trees does to their local environment. This is a cycle that we can keep on repeating, meaning that over a long time this process can count as renewable. By not burning non-renewable energy sources, such as coal or gas, or trees that are never replanted, we are trying to save on carbon emissions If we plant new trees, they will absorb roughly the same amount of carbon that burning trees will release, but this can take many years.īalancing out the carbon released and carbon absorbed is known as being carbon neutral. īurning wood only releases as much carbon into the atmosphere as the tree that it comes from absorbed as it grew. Some people say this is not a good idea because it is destructive and gives off air pollution. We can burn trees and wood to use the energy given off. On the downside, growing crops for fuel uses a lot of land, and burning biofuels does cause pollution. So, Biomass is renewable and he can use our waste to make They process it into dried pellets, which are then burnt instead ofĬoal or gas, saving a lot of carbon emissions. The digester captures the natural gas given off as the food rotsĪnd uses it to generate heat and electricity.Īt Daldowie Fuel Plant near Glasgow they deal with raw sewage.Īfter the water has been separated and cleaned, they’re left with You know the little food waste bins you have in your house?ĭeerdykes Bio-resources Centre in Cumbernauld takes all thoseīits of pizza crust and apple cores and processes them in an There’s one other big way that Biomass can provide us withĮuchhh. Like diesel made from sugarcane, or alcohol made from corn which can be used to power vehicles. So, if we keep growing as many trees as we burn, we’re notĪdding to the carbon dioxide in the atmosphere.īut you’re not just about wood, are you Biomass? That burning releases carbon dioxide, but only as much as a like burning wood to heat homes, or to generate electricity. So it’s anything that comes from plants, or animals, which can be You wouldn’t want to invite him round to tea at your granny’s Meet Biomass – he's an important source of energy.
