Waste to Energy- Its Projects and implementations

What is Waste to Energy?

Waste-to-energy (WTE), is a term that refers to a variety of technologies that convert non-renewable waste into energy such as heat, gasoline, and electricity, WTE Production Many methods can be done including combustion, gasification, and firewood. Anaerobic digestion and gasification

The term WTE is used primarily for boilers that completely burn waste at high temperatures to produce energy. Modern furnaces use heat-absorbing devices to prevent the release of components into the atmosphere. It is currently the only economically viable and commercially viable option for WTE.

Another example of WTE is anaerobic digestion (AD). It is an old and efficient technology that converts organic matter into biofertilizer and biogas into energy. The AD system works well and serves all communities with income levels, from low tech to high tech. Another process called pyrolysis can turn waste into a hot, flammable fuel.

Finally, landfill gas recovery refers to the process of recovering municipal waste and converting it into energy. The most common way of collecting is to collect, dig and dispose of vertical or horizontal pits in the landfill using fans and purifiers.

Waste to Energy Project

One of the waste management features of LWMC is the generation of energy from municipal solid waste (MSW), reducing waste generation by 80%. ECOAIR, an American waste-to-energy (WtE) company, has acted as an advisor to the LWMC government on WtE projects. ECOAIR conducted a feasibility study for WtE and based on the characteristics of MSW Lahore, it was suggested that CFBC technology is the best technology for WtE. LWMC investigated the removal of MSW between 2011 and 2014.

To start the WTE project, the Punjab Power Development Board (PPDB) has sent a letter of interest (LOI) to a Chinese independent producer (IPP) company to set up a WTE project with a capacity of approximately 40MW.; M/s China ENFI Engineering Corporation (ENFI) JV and MCC Tongsin Resources Limited (MCCT)

M/s ENFI/MCCT Consortium selected the site in Lakhodiri for the WtE project and conducted a feasibility study for the waste management of the power plant. VTE’s domestic power plant is expected to be built with a waste handling capacity of 2,000 tons per day, a capacity of 670 tons per day, 3 grid sets, and 2 generator sets with condensing turbines. It has a capacity of 20 MW and nominal power. The average calorific value (CV) of waste is 6220 kJ/kg.

LWMC has committed to supply 2,000 tons of MSW per day to existing IPP investors in Lahore and 3,000 tons per day of PPDB for the next 40 MW WtE project. Many entrepreneurs have shown an interest in investing in WtE projects.

Booti Dumpsite Gas Flaring Project – Waste to Energy

Mahmood Booti is the oldest landfill, operating since 1998. The landfill comprises about 320 kanals (40 acres/16 hectares). Capacity decreased and the landfill was closed in April 2016 as the area reached 80 meters above ground level. About 13.14 million tons of garbage were dumped at Mahmood Boot. The biodegradable fraction of waste that goes to landfills is 55-60%.

Plantation Drive

LWMC has taken the initiative as a pilot project to create pastures on the ring road. To date, LWMC has planted 14,500 tree species on an area of approximately 20,000 m2. After cutting and leveling the necessary pieces, we would plan it.

Gas Assessment Pilot Project

LWMC has started a project to get gas flow into the hall from the southeast of Mahmood Booti Hall. In this project, four (04) gases will be collected from four gas turbines installed at the landfill and transported to the point via a 900-meter pipeline to be tested and incinerated. On June 13, 2018, LWMC installed the necessary equipment, including two burning stoves and gas lamps in the relevant facilities to demonstrate gas consumption.

Environmental Benefits

Note here that methane has 56 times the global warming potential in 20 years and 21 times more than carbon dioxide (CO2) in 100 years. A tree (21.7 kg) can absorb CO2 at a rate of 48 lbs. Every year. Gas drains installed in landfills discharge about 1 cubic meter of gas in 24 hours, which corresponds to 8 kg CO2/day and 2920 kg CO2/year. In other words, by emitting just 365 m3 of methane per year, the LWMC saves the environment no less than 138 trees per year.


It is estimated that landslides will continue to provide fuel gas for the next 7-10 years at least. The gas collected in the landfill can be given to the nearest unit of LWMC to meet its energy requirement. The first work of the project has begun.
