Waste To Energy

One of the components of LWMC’s waste disposal is generation of energy from Municipal Solid Waste (MSW) by reducing volume of waste up to 80%. ECOAIR, a US based Waste to Energy (WtE) firm was hired as official consultant of LWMC on WtE project. ECOAIR had conducted a feasibility study on WtE project and depending upon the characterization study of MSW of Lahore City, it was recommended that Circulating Fluidized Bed Combustion (CFBC) technology is most suitable technology for WtE. LWMC has conducted waste characterization study of MSW from 2011 to 2014.

For establishment of a WTE project, Punjab Power Development Board (PPDB) issued a Letter of Interest (LOI) to the following Chinese company as Independent Power Producer (IPP) for establishment of approximately 40 MW WtE project; M/s China ENFI Engineering corporation (ENFI) JV with M/s MCC Tongsin Resources Limited (MCCT)

M/s ENFI/ MCCT have registered their company in Pakistan with the name of SPV Lahore Xingzhong Renewable Energy Co. Ltd.

M/s ENFI/ MCCT Consortium has selected Lakhodair site for WtE project, and conducted feasibility study for installing Grate Incineration waste to Energy plant. It is planned to build a domestic WtE power plant with 2000 t/d waste processing capacity, equipped 3 sets of 670 t/d grate waste incineration furnaces and 2 sets of rated 20 MW condensing turbo generator sets. Average Waste Calorific Value (CV) assessed is 6220 kJ/ kg.

LWMC has assured to supply 2000 tons of Municipal Solid Waste (MSW) on daily basis for 40 MW WtE project and has further assured 3000 Tons/Day waste supply to PPDB for next WtE Projects for Investors as IPP in Lahore, as many investors have shown their interest for investment in WtE Project.

Mahmood Booti is the oldest dump site located at Ring Road, operational from 1998. The estimated area of dumpsite is around 320 Kanals (40 Acres / 16 Hectors). This site has exhausted its capacity and attained the height of about 80 feet from the ground level, therefore the dumping was closed in April 2016. According to an estimate approximately 13.14 million tons of waste has been dumped at Mahmood Booti. The biodegradable fraction of dumped waste is 55% to 60%.

LWMC has taken an initiative for plantation on front façade of dumpsite facing Ring Road as a pilot project. Till now LWMC has planted 14,500 plants of different species on front elevation covering an area of Approximately 20,000 m2. The planation has been done after necessary cutting and levelling of the area.

LWMC has taken an initiative to access the Dumpsite gas potential on south eastern side of Mehmood Booti Dumpsite. During the trial project Gas from four (04) identified Gas Vents already installed at dumpsite was collected and transported through 900 feet long gas pipeline to one point for testing and flaring. Since 13th June 2018, LWMC has installed necessary apparatus including a two-burner stove and a gas lamp in allied office to flare the gas for demonstration.

It is worth mentioning here that Methane has 56 times of Global warming potential for 20 years and 21 times for 100 years more than Carbon dioxide (CO2). A single tree can absorb CO2 at a rate of (21.7kg) 48 lb. per year. The gas vents installed at dumpsite are releasing approximately 1 cubic meter gas in 24 hours which is almost equal to 8 kg CO2/day and 2920 kg CO2/year. This means by flaring only 365 m3/year Methane Gas, LWMC is protecting the environment same as done by 138 Trees in a year time.

It is estimated that dumpsite has potential to supply the combustible gas for at least next 7-10 years. Collected dumpsite gas can be supplied to LWMC nearby facility to fulfil its electricity needs. Initial work has been started o this plan.

Rehabilitation of Mahmood Booti, Old Dumping Site is also initiated. LWMC has closed the site and as a pilot study, LWMC in collaboration with PHA has planted 14500 plants. LWMC has also taken an initiative to access the Dumpsite gas potential on south eastern side of Mahmood Booti Dumpsite. It is worth mentioning here that Methane has 21 times for 100 years more than Carbon dioxide (CO2).

• LWMC has captured and utilized the 906 Cubic Meter dumpsite gas
• Gas having (18 MMBTU’s) till now at amount of Rs.10,580
• Environmentally this pilot project has saved 7 tons of carbon credits
• This project is working for 641 trees as one tree absorb 21.7 Kg of CO2 in one year.

Pilot project “Offal’s to Energy” In the year 2018, on Eid ul Azha which is a festive occasion of animal sacrifice, LWMC has collected a total of 4500 tons of Offal’s from the entire Lahore during three days event.
• LWMC took an initiative on “Offal’s to Energy” pilot project. For the said pilot project, after collection of 15 tons of Offal’s
• It is estimated that 500 cubic meters of gas having 11.11 MMBTU’s shall be collected during entire assessment.
• It will also help to cover 4 carbon credits and during entire assessment
• This project will be working to serve as 193 trees.
