Harnessing Methane from the Ojota Dump.



The Infamous Garbage dump of Ojota in Lagos is probably producing enough methane gas that could run a 100Mw power station. Getting certain important infrastructure like laying pipes now that will collect the methane gas in the future should be encouraged by the state govt to potential IPP consortium's.

A dual gas(Methane/Natural Gas) IPP(Independent Power Plant) generation plant located in Ojota will help fill the power deficiency void that the state currently sits in. Success of such a plant will probably encourage the establishment of plants that will recover methane from the biodegradability of human and animal waste. Sewage or Septic tank disposal trunks could them be instructed to dump their goods at the processing plants rather than in the Lagoons of Lagos as they currently do.

Green Energy from the Makoko sawdust heaps




The sawdust heaps that currently grace the shanty skyline of Makoko that are visibly while driving south bound on the third main land bridge can be converted to clean electrical energy. The fuel sawdust is generated presently in very large amounts which currently end up being set on fire to reduce its bulk because it seen as a nuisance and potential hazard for the timber mills in the area.

If a plant Gas turbine generator that is suited for wood gassification power generation is incorporated in the power plant enough methane gas will be produced to generate large amounts of clean energy for the city. About 1.8 tonnes of sawdust is believed to be capable of generating 2.43MW of electrical power and taking a wild guess the tonnage of sawdust burnt in Makoko should be about 100 to 200 tonnes per day if not more.

Other by products from such a plant could be a sea water desalination plant for Makoko and Yaba that uses residual heat from the turbine exhaust to boil and recover clean water by condensing the steam.
