How does a food waste treatment system help reduce Greenhouse gas emissions?

There are millions of tons of animal waste and food waste generated every year and its disposal is a significant issue. CHUGG- an innovative food waste treatment system in India with an Anaerobic Digester (AD) converts food waste into immense amounts of methane, which is an exceptionally encouraging innovation for converting food waste into renewable fuel source/ manure. Biogas could be utilized to cut worldwide ozone Greenhouse gas emissions by up to 10-13%. Food waste treatment in India is accomplished through the generation of environment-friendly renewable gas named biogas derived from the anaerobic digestion of organic waste.

Organic wastes generate a lot of methane when discarded in landfills as they break down. Methane is an incredible Greenhouse gas that traps heat in the atmosphere more efficiently than carbon dioxide. Given equivalent measures of methane and carbon dioxide, methane will assimilate multiple times more heat in 20 years than carbon dioxide. To diminish Greenhouse gas emission and the impact of pollution organic waste can be segregated and used to generate biogas a renewable source of clean energy. While reducing fossil fuels, biogas makes further emission reductions, resulting in reducing the carbon footprint.

CHUGG- an innovative food waste treatment system in India that generates Biogas by treating food waste ‘in-situ’ which means at source. This way it tackles the issues of greenhouse gas emission, climate change, and complies with municipal & SWM rules. Here are a few ways in which CHUGG reduces the emission of GHG into the atmosphere.

Captures Methane

Methane (CH4) is one of the primary, harmful Greenhouse gas. The odorless, colorless, combustible gas is potent, in light of the fact that it is 21 times more effective at trapping heat from the environment than carbon dioxide (CO2) over a timeframe of 100-years. In other words, it takes 21 tons of CO2 which is equal to 1 ton of CH4. CHUGG- an innovative food waste treatment system in India is attached with a chamber in which organic waste is crushed with water before inducing into the system. Once the waste is fed it breaks down in the absence of oxygen to release Methane which is captured inside a Chamber. This produces two byproducts namely Biogas, and Bio-slurry. Biogas can be used for cooking which is transported to the kitchen stovetop through a pipeline and the digestate produced is used as an organic manure for plants. Therefore capturing Methane through anaerobic digestion is beneficial because it reduces the emission of greenhouse emissions from organic waste matter and provides us with renewable energy, and organic manure.

Produces heat

The heat generated from the Biogas plant is used as a substitute for fossil fuel. This reduces the amount of fossil fuel used and deforestation. Burning fossil fuel generates a large amount of Greenhouse gas into the environment. Hence Biogas generation significantly reduces the impact of deforestation in turn reducing greenhouse gas emission.

Digestate as Fertilizer

When the mixture of food waste and water is fed into CHUGG- food waste treatment system it undergoes a series of anaerobic digestion to produce Biogas. The residue of the digestion is named Bio-slurry. Bio-slurry which is another by-product of CHUGG is a potent organic fertilizer that retains its original nutrients present in the feeding material. Unlike composting Bio-slurry is odorless and does not attract pests. It reduces weed growth by 50% and is an excellent soil conditioner that improves the capacity of the soil to retain moisture. Proper utilization of Bio-slurry has proven to provide higher yields than regular fertilizer. It also provides viable nutrients thus considerably boosts agriculture, and horticulture productivity.


CHUGG- an innovative food waste treatment system developed by AVRIS Environment technologies LLP converts food waste to heat, electricity, and soil conditioner. This renewable source of energy reduces greenhouse gas emissions and improves environmental quality. CHUGG is a great opportunity to recycle nutrients in food waste to displace fossil fuels and chemical fertilizers. CHUGG is a one-stop solution that solves multiple problems by creating multiple benefits.
