Landfill gas-to-energy (LFGE) refers to the capture and utilization of the methane gas generated by the decomposition of waste in landfills. In India, this technology is being adopted to reduce greenhouse gas emissions, generate electricity, and improve air quality.
Here are some of the ways that landfill gas is being used for energy in India:
Electricity Generation: Landfill gas can be used to generate electricity in combined heat and power (CHP) plants. The methane gas generated by landfills is burned in a generator to produce electricity, which can be used on-site or fed into the electrical grid.
Vehicle Fuel: Landfill gas can also be cleaned and compressed to produce compressed natural gas (CNG), which can be used as a fuel for vehicles. This helps to reduce emissions from transportation and can also provide an alternative source of fuel for vehicles.
Industrial Process Heat: Landfill gas can be used to provide heat for industrial processes, such as drying and heating. This can help to reduce energy costs and improve energy efficiency.
Following are some of the notable landfill gas-to-energy projects in India:
Delhi International Airport Limited (DIAL): DIAL operates a landfill gas-to-energy plant at the Indira Gandhi International Airport in Delhi. The plant captures the methane gas generated by the landfill and uses it to generate electricity, which is used to power the airport's operations.
Ghazipur Landfill Site, Delhi: The Ghazipur landfill site in Delhi has been equipped with a landfill gas-to-energy plant that captures the methane gas generated by the landfill and uses it to generate electricity. The electricity is fed into the grid, providing a source of renewable energy for the city.
Mumbai Metropolitan Region Development Authority (MMRDA): MMRDA has established a landfill gas-to-energy project at the Deonar landfill site in Mumbai. The project captures the methane gas generated by the landfill and uses it to generate electricity, which is fed into the grid.
Krazy Castle Landfill Site, Pune: The Krazy Castle landfill site in Pune has been equipped with a landfill gas-to-energy plant that captures the methane gas generated by the landfill and uses it to generate electricity. The electricity is used to power the site's operations and also fed into the grid.
These are just a few examples of landfill gas-to-energy projects in India. There are likely many other projects in various stages of development and implementation throughout the country.
Overall, landfill gas-to-energy is a promising technology that has the potential to help India reduce its greenhouse gas emissions, generate electricity, and improve air quality. The government has been promoting the adoption of this technology through various initiatives, such as providing financial incentives and technical support to companies that are involved in LFGE projects.
