Biogas or Fossil fuels??

Biogas, we all have been taught about it once, twice and many times during our school times but except learning only the definitions we have ignored it for so long. Even after learning about “stop depletion of natural resources” , “maintain the usage of non-renewable resources”, we carry on the depletion.

Biogas is produced through the processing of various types of organic waste in biogas plant. It is a renewable and environment friendly fuel made from 100% local feedstocks that is suitable for a diversity of uses including, road vehicle fuel and industrial uses.

Biogas plant is a low cost set up and rely on the anerobic conditions ( without oxygen). The raw material used for this are agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Microbes feeds on the biomass which releases methane and other gases, which can be used in the place of natural gas. Material containing organic nutrients is also produced in the process, and this can be utilized for purposes such as agriculture.

Stages in biogas production…

Biogas is produced using well-established technology in a process involving several stages:

1) Biowaste or our raw material is first been crushed into smaller pieces and slurrified to prepare it for the anaerobic digestion process. Slurrifying means adding liquid to the biowaste to make it easier to process. The thick slurry of waste poured into big tanks or under ground tanks.

2) Microbes need warm temperature conditions, so the tank with slurry heated up to 37 °C.

3) Now, the actual production starts under suitable conditions and it take 3 weeks to complete the procedure.

4) In the end, the gas is being purified by removing impurities and CO2 and making it suitable for use.

All of this carried out in a Biogas digestors, are the systems that process waste into biogas and then channel that biogas so that it can be used as a form of energy and used productively. There are several different types of biogas digestors and plants that have been designed to make the process efficient. While each model differs depending on input, output, size, and type, but the biological principle is uniform in all types of plants. Now as we have revised biogas, let’s talk about fossil fuels. For more than a century, burning fossil fuels has generated most of the energy required to propel our cars, power our businesses, and keep the lights on in our homes. Even today, oil, coal, and gas provide for about 80 percent of our energy needs, while knowing about the fact the burning fossil fuels cause pollution. There are a lot of disadvantages of fossil fuels like- Water pollution, land degradation, toxic air pollution, global warming, ocean acidification and many others.

Choosing biogas over fossil fuels is the best we can do to heal our mother nature again.
