What is Biogas? Sources and benefits of Biogas

food waste treatment in India

Renewable power is turning into an increasingly significant issue these days. The World right now depends intensely on coal, oil, and gas for its energy. Non-renewable energy sources like fossil fuels, coal are drawn from finite sources that will in the end diminish, get excessively costly, or environmentally damaging. Due to the increasing expense of fossil fuels and the threat of Climate Change, there have been positive advancements in this field. 

These advancements have enhanced the interest in a cleaner and more economical techniques of renewable energy. However, there are various kinds of renewable energy sources accessible like solar, biomass, tidal, wind, and so on each kind of energy has its benefits just as its disadvantages. 

What is Biogas?

Biogas is often referred to as green energy, clean energy, and alternate energy source. This energy is obtained from natural resources that are not replenished or otherwise endless like the sun or the ocean. It is an alternative to most of the non-sustainable sources used widely today like coal, fossil fuel, etc. In many places, Biogas has been generated in both small and large scale plants for instance a house biodigester that provides cooking gas for an entire family and a large scale biogas plant that can generate energy for a whole community. 

Composition of Biogas

Biogas is composed of methane, carbon dioxide, and traces of other gases such as Nitrogen, hydrogen sulfide, hydrogen, and oxygen. The composition differs depending on the source of production, raw material used, organic matter loaded, and the feeding rate of the digester.

How biogas replaces fossil fuel?

Biogas is carbon neutral hence the environmentally less damaging way of obtaining energy from organic waste matter by eliminating Methane emission into the atmosphere. The impact of biogas generation on the environment is much lesser than the impact of fossil fuels, and natural gas. Biogas is extensively used in some rural areas for electricity and cooking. Hence Biogas generation is one of the most effective ways to reduce the use of fossil fuel and greenhouse gas emissions.

How CHUGG-food waste treatment system produces biogas?

CHUGG-An innovative food waste treatment system is a one-stop solution for all problems associated with food waste treatment in India. It is an affordable household bio-digester that can be installed in your home, industry or any entity where food waste management is a hassle. CHUGG effectively uses your food waste, kitchen waste, and garden trimmings and converts them into Biogas, and manure thereby reducing the production of greenhouse gas Methane.

The food waste is crushed form is processed in anaerobic digesters to produce Biogas and bio-slurry as two byproducts. CHUGG comes in two variants namely CHUGG 35, and CHUGG 75 providing cooking fuel and manure for homes. 

Sources of Biogas

  1. Livestock waste

Livestock/ cattle and poultry waste comprise the most utilized substrate for biogas generation. Manure from poultry, dairy cattle, and pigs are largely genuine instances of this waste. This organic matter can be exposed to controlled deterioration to yield great amounts of bio-methane.

  • Landfill gas

This energy generation technique utilizes aggregated wastes from domestic exercises to create biogas. Landfills are loaded up with appropriate organic materials that break down generating biogas that is modified and provided to various processes.

  • Activated Sludge from Waste Treatment Plants

Sludge got from wastewater sanitization is generally composed of organic materials accordingly forming a rich substrate for biogas generation. Whenever wastewater has been filtered through, activated sludge buildup in the treatment plant can be diverted to particular disintegration chambers where they produce methane.

  • Industrial, Institutional and Commercial Wastes

Numerous modern industrial manufacturing units utilize organic raw materials that are abundantly available in nature in their production. For instance, food product manufacturing industries use food materials that produce tremendous measures of organic waste matter. Biogas generating plants can outfit these materials, permitting controlled disintegration to yield environmentally friendly power through biogas.

Benefits of generating Biogas

The fundamental advantages that a biogas generation can provide us are as follows

  1. Biogas is a solution for food waste management. Any decomposable organic waste is converted into cash.
  2. A food waste treatment system that controls the emission of CH4 methane is multiple times more polluting than CO2, which is a typical way would have been released into the atmosphere. Now catching it and converting it into energy is a more advantageous process. 
  3. Food waste treatment system additionally prevents the emission of CO2 from different other processes, for example, burning fossil fuel or oil that would have been vital for the generation
  4. By diverting food waste from a landfill to a food waste treatment system we acquire monetary advantages and occupations in the biogas plant itself, improving the economy.
