Advantages And Disadvantages Of Biogas

Biogas is an eco-friendly, renewable energy source which is created through a process known as anaerobic digestion, in which microbes break down organic materials, such as food or animal manure, without the presence of oxygen. The waste material must be contained in an environment with no oxygen for this to happen. Biogas can be produced artificially or organically as part of industrial processes for fuel and its presence can be detected by a Biogas analyser. Biogas is produced when a range of waste materials, such as animal manure, sewage, plant material, and municipal trash or garbage, decompose. Methane and CO2 make up the majority of biogas. Additionally, it could contain a little moisture, siloxanes, and hydrogen sulphide. Additionally, if biogas is improved to natural gas standards and cleaned up, it is referred to as biomethane and may be utilised similarly to methane, such as for cooking and heating.


Advantages of Biogas

  1. Eco Friendly

Bio digestion produces non-polluting gas that actually lowers greenhouse gas emissions. Global warming can be prevented by utilising gas from waste as a source of energy because there is no combustion involved and no release of greenhouse gases into the environment.


  1. Reduces soil and water pollution

Not only do overflowing landfills spread unpleasant odours, but they also make it possible for poisonous chemicals to enter underground water supplies. This is the reason why equipment like the Mru optima 7 biogas analyzer is used to detect biogas presence. The production of biogas could enhance water quality. Anaerobic digestion also makes bacteria and parasites inactive, making it a potent tool for lowering the frequency of waterborne diseases. 


  1. It helps in producing Organic Fertilizer

Richened organic digestate, a byproduct of the biogas generating process, is an excellent addition to or replacement for chemical fertilisers. Commercial fertilisers contain compounds that have hazardous effects and can, among other things, cause food poisoning, whereas the fertiliser outflow from the digester can speed up plant development and resilience to diseases.


  1. Biogas generation is a cost affordable technology

The technology utilised to create biogas is rather affordable. When employed on a small scale, it requires little setup effort and expense. Tiny biodigesters that utilise animal manure and kitchen waste can be used at home. The gas generated may be utilised right away to generate energy and for cooking. Because of this, the price of producing biogas is comparatively low.


Disadvantages of Biogas

  1. Contains impurities

Impurities remain in biogas even after it has been compressed and refined. The metal components of the engine may rust if the produced biofuel was utilised to power automobiles. The expense of maintenance would rise as a result of this corrosion. For water boilers, lights, and cooking burners, the gaseous mixture is far more suited.


  1. Affected by weather

The weather has an impact on biogas production much like it does on other renewable energy sources. About 37°C is the ideal temperature for bacteria to digest waste. Digesters need thermal energy to ensure a steady supply of biogas in cold areas.


  1. Not suitable in all areas

The fact that industrial biogas facilities only make sense when raw materials (food waste, manure) are in abundant supply is another drawback of biogas. Because of this, rural and suburban regions are significantly more suited for biogas generation.


  1. Technological challenges

The ineffectiveness of the techniques utilised to produce biogas today is a regrettable drawback of the fuel. There are currently no innovative solutions to streamline the procedure and make it affordable and accessible. This implies it is still not feasible to produce on a sufficient scale to meet the needs of a huge population.
