Appendix – 1
BASIS OF CALCULATIONS
(For Table – 4 in main Text)
Flow of Activities: 500 Tons/Day
The flow of activities in this option is given below.

- Waste disposed and spread out on a flat 2,500 M2 platform
- Scavenging teams pick glass, paper, plastics, bones and textile
- Waste drying
- Metal picking by magnetic extractors
- Waste pushed/carried towards landfill site
- Waste spread and compacted by manual rollers
- Recycleable material transferred to sorting and storage yards and from there to nearby recycling industry

Source of Funds
For the development of one landfill site Rs 171,105,000 or US$ 2.7 million is required. For the development of all four sites Rs 684,420,000 or US$ 10.7 million is required. These are not large sums and can be acquired from the Government of Pakistan or the District Governments Annual Development Plan (ADP).
Revenue From 500 Tonnes/Day
Table – 5
| Revenue Per Year (in Rs.) | ||
|---|---|---|
| Estimated market price of waste material sorted if all picking activity is moved to the landfill site. Dealers willing to pay 2.5 % of this if freedom from bhatta is guaranteed | Rs. 200,000/day | 1,825,000 |
| Ex-factory value of recycled waste | Rs 547,500,000/year | |
| Recyclers will to pay 1 % of this if infrastructure and utilities are guaranteed. Reduce by 25 % since 25 % of industry will remain outside of landfill | Rs 438,000,000/year | 4,380,000 |
| Land rent at Rs 7,500 per month from 6 factories | 540,000 | |
