Production of thermoelectric power from the solid waste of Bhangalii Village

The work reported in this article was undertaken to study the viability of production of thermoelectric power by incineration of biomass content of Bhangalii Village solid waste. The data concerning the production and disposal of solid waste were collected from Bhangalii Village situated in Union Council No. 6, District Aziz Bhattii Shaheed Town Lahore. The primary data concerning the production of thermoelectric power from the solid waste such as bagasse were collected by visiting Pattoki Sugar Mill. The prices of machinery and equipment were also supplied by the Mill authorities, which were verified by visiting the websites of different local manufacturing companies. The data were used to design the projects subsequently appraised to determine their Benefit to Cost (B/C) Ratio, Net Present Value (NPV) and payback period (PBP). Currently Bhangalii Village consumes 1,481,528kWh of electricity per annum and it produces approximately about 800 tons per annum of solid waste. The electricity that can be produced with this weight and its composition is 247, 267 kWh/annum. The B/C ratio at this scale of production was 0.14, which is less than 1(the reference standard), NPV was-$1,026,444 (below zero) and the payback period infinite. Thus, the project is not feasible in this scenario for the Bhangalii Village. However, the project becomes feasible if the waste produced by some neighboring colonies and not by village itself disposed near the Bhangalii Village is taken into account for the projection because B/C ratio in this case becomes 1.28, NPV $401,808 and PBP1.56 years.
