8. Cont…..
Roughly 20 million tons solid waste is generated with
2.4% growth each year.
Potential of 1000 MW is available through Municipal
Solid Waste.
City wise waste and estimated generation of
electricity is as under:
 Karachi 15,000 ton per day 300 MW
 Lahore 8,000 ton per day 160 MW
 Peshawar 1,000 ton per day 30 MW
 Quetta 300-400 ton per day 10 MW

Solid Waste Management at Urban Level

9. Solid Waste Management at Urban Level
Peshawar generates 800-1000 ton waste per day
The garbage is dumped at temporary sites
identified by WSSP
The Peshawar City has potential of 30 MW
20-25 Acre land will be required for 30 MW

11. Private Sector :
Power & Energy Development Corporation
• The PEDC is an authorized consultant of
Hangzhou- Jinjiang Group China. It is a
Chinese company that has authorized PEDC to
contact District Local Authorities of Pakistan
for waste to energy (WTE) project proposal &
implementation.
• 500 tons/day MSW generate 10 MW

12. Modes of Project Implementation
• Public Private Partnership (PPP) for commercial
agreement between Hangzhou Jinjiang group & local
government or its associated company. Following are
the wide range of contractual options of which
anyone could be opted
 Built –OWN- Operate (BOO)  Built–Own-Operate-transfer
(BOOT)
 Built- Transfer(BT)  Built- transfer and Operate(BTO)
 Built –Operate and
transfer(BOT)
 Built-Lease-Transfer(BLT)
 Joint Venture (JV)

13. Benefits of the WTE projects
• Cleaner environment as a result of elimination of
municipal waste
• Recovery of recyclable material of more than 50%
• Conversion of waste into useful product like power /
energy.
• Gain of carbon credit from international agencies
• Furnace ash collection & reutilization as bricks and
roads paving materials
• Energy self-reliance and savings in much needed
foreign exchange.
• Jobs for local human resource both in permanent and
contractual category.

15. Solid Waste Management at Urban Level
Project.3
Project Name: Construction and Development of Compost Plant in
Peshawar City
Project Cost: 2 billion PKR (tentative cost)
• Composting is an aerobic biodegradation process used to decompose organic
material
• Around 300 tons of MSW can be processed through composting plant and the
composting is suitable in Pakistan because of the below reason
• High moisture content, high Carbon Nitrogen (C/N) ratio and low value of
volatile content of solid waste
• Cheap process.
• Environment friendly
• 100% natural, no chemical addition
• Improves soil strength - therefore it is called soil conditioner / supplement
• Improves fertility of soil through pure organic matter
• Increases water holding capacity of soil
• Act as natural pesticide
• In ecosystems, it is useful for erosion control, land and stream reclamation,
wetland construction, and as landfill cover.

16. Compost Plant (Reference Lahore)

17. Process at Compost Plant
Compost processing is done through aerobic decomposition
using Windrow technology without any addition of chemicals.
Windrow means a long heap of regular shape and cross
section, prepared with the organic material.
The composting process normally takes around 60 days to
complete.
The plant and machinery supplied by MENART of Belgium, has
a capacity to produce around 40,000 MT of compost per
annum.(Lahore Compost)

18. Process Benefits
Composting process employed not only
controls the emission of Green House Gases
(GHG) to the environment but also turns the
organic material extracted from MSW into a
useful product which eventually go back to the
soil, hence facilitates effective and efficient
management of waste.

19. Compost Making Operations
Compost making operations include:
1. Sorting of MSW
2. Shredding of compostable material and
mixing
3. Windrows management
4. Compost sieving and bagging

20. What is Compost?
Compost is a stable, humus like product resulting from
the biological decomposition of organic matter under
controlled conditions.
Controlled biological decomposition process is what
differentiates composting from the natural
decomposition of organic matter.
Organic materials are decomposed regardless of
whether or not we compost them, but regulating and
optimizing conditions ensures a faster and environment
friendly process, thus producing quality end product.
