Tapuwa Ndongwe: CLEAN ENERGY PLANT FROM WASTE TIRES AND PLASTIC IN
Connect me to Tapuwa Ndongwe
While Nairobi comprises only 0.1% of all the land in Kenya, it accommodates 10% of Kenya’s population. Sprawling slums, inadequate health facilities, outdated transport infrastructure and a waste disposal system literally bursting at the seams are just some of the woes the Nairobi County government has to address. Conspicuously missing from that formidable list is the environmental impact that these rigors of rapid urbanization have on the city. One of these is the growing number waste tires and plastics in landfills. Nairobi accounts for 60% (30,000 tons equivalent) of all waste tires in Kenya. As for plastics Nairobi produces 211,315 tons/year . On average, 27,500 tons of waste tires are burnt annually to salvage scrap metal and 82% of the plastic annual consumption (i.e. 173,278 tons/year) is either disposed of in landfills or burnt. Due to lack of financial incentives, there is currently no sustainable alternative to dealing with this waste.
We propose to set up an energy efficient project that converts waste tires and plastics into electricity by running a generator fueled by pyrolysis oil. The plant will be located within a 40km radius of the Nairobi Central Business District as this will be the main source of our feedstock. The project is configured around two sets of stakeholders: the feedstock suppliers (sourced from the informal sector) engaged through off-take agreements, and the market comprised power off-takers either directly (commercial power consumers) or through the grid in the form of a Feed in Tariff (FIT).
