<h3 /><h3>What is biogas?</h3>
Biogas is a combination of gases made from agricultural waste, manure, municipal trash, plant material, sewage, green waste, and food waste.
Biogas
-Biogas is a mixture of <u>Methane </u>and <u>carbon dioxide.</u>
-It is produced when <u>microorganisms </u>digest waste material.
-Biogas is burned, and the energy can be used for <u>cooking,eating</u> and<u> lighting.</u>
Bioethanol
-Ethanol can be made by<u> fermentation.</u>
-Fermentation is the process of using <u>yeast </u>to convert the sugar into ethanol.
-Carbon dioxide is always produced.
-The fermented mixture can be <u>distilled </u>to produce more concentrated biogas.
-Bioethanol is quite cheap to produce.
-Ethanol can be used as a fuel, it only gives just <u>carbon-neutral carbon dioxide </u>and <u>water.</u>
Advantages: Crops grown for bioethanol production take-in <u>water</u>, <u>carbon di oxide</u> from the atmosphere. This goes some way toward bioethanol<u> carbon dioxide</u> and <u>water.</u>
Disadvantages: The price of crops <u>can increase</u> growing plants for the production of bioethanol may mean that land
-Bio-fuels-what are they and where they come from?
-Biofuel is fuel made from the<u> living organisms </u>or a by-product of <u>waste,</u> and <u>vegetable oil.</u>
-Biofuel currently being produced from <u>waste</u>, <u>vegetable oil </u>and sugarcane is already sustainable.
It comes from planting crops that can be <u>planted </u>and <u>harvested </u>every year.
Advantages:
Bio diesel is less <u>expensive </u>than regular diesel.
Releases less <u>pollution </u>than ordinary diesel.
Disadvantages: We can't make enough. Biodiesel is <u>Toxic</u>
<u></u>
Hence, Biogas is a mixture of <u>Methane </u>and <u>carbon dioxide.</u>
