Bio CNG
Bio CNG brings to us a two-faceted advantage. On one hand, it is an effective way to dispose of wet waste and convert it efficiently into energy. On the other, it gives an amazing alternative for fuel with more calorific value and less carbon footprint.
SWMS, in its commitment to focus on Waste-to-Energy projects by the Government, has engaged with the Greater Chennai Corporation to set up a Bio CNG plant in Egmore, Chennai.
Bio CNG presents an efficient way to create wealth from waste, and in an area that specifically matters - fuel!
In the urban areas, there is a constant need to efficiently manage MSW wet waste, and Bio CNG is one of the most effective methods to do so. It is produced using a patented technology and its by-product is bio manure which has a wide spectrum of applications in agriculture.
Bio CNG is a more purified form of biogas as it contains about 92 to 98% methane and 2-3% carbon dioxide compared to the normal biogas that has about 55 to 65% methane and 35-45% carbon dioxide. The result of the increased methane content is its energy efficiency - Bio CNG produces 52000 Kilojoules/Kg which is markedly better than biogas that produces about 19500 Kilojoules/Kg
The high calorific value of Bio CNG would mean that it can be used for power generation and as an environment-friendly fuel. It also doesn’t leave any residues as it is completely used up unlike LPG.
The calorific value of Bio CNG is slightly higher than LPG, making it an ideal candidate for commercial cooking, replacing LPG cylinders.
SWMS with a joint PPP venture with Greater Chennai Corporation (GCC), had constructed 100 metric tonnes capacity plant at Chennai. It will produce about 4000 KGs of Bio-CNG and 10 metric tonnes of bio manure every day. This will be one of the iconic projects in South India.
It’s a zero-waste technology and forms a critical part along with composting units in the overall waste management cycle
Many local restaurants are already engaged with SWMS for the Bio CNG supplies.
SWMS has plans to implement more Bio CNG plants across India to create clean energy in pursuit of a greener environment.
MSW wet wastes are collected and fed into Bio CNG plants
There are a series of processes and machinery operations like feeding conveyors, digesters, storage, balloons, compressors, cascade cylinders and appropriate vehicles.
The process produces Bio CNG and manure
