Recovering energy from waste can power Africa | Source: by David Kariuki, Cleanleap, Feb 10 2016.
Production of electricity from waste has the potential of providing up to 83.8 TeraWatt hours (TWh), which is about 20% of the electricity needed in Africa by 2025. This is according to a study co-authored by the European Commission Joint Research Centre (JRC). However, this requires stringent waste management policies to be put in place, and today Africa lacks the adequate infrastructure needed to install these environmentally friendly methods.
Like some other parts of the world, most of the waste in Africa is burned without tapping the potential of gases (which usually end in pollution) or dumped in landfills without protecting groundwater. Many of the developed countries that have a high percentage of waste to energy recovery, have strict emissions laws that regulate waste handling.
Waste in Africa, according to JRC, can be used to produce energy in two ways. The first is using Waste-to-energy (WTE) incineration plants where the trash is burnt to produce steam that turns turbines. The report notes that these are few in this part of the world because of the high initial costs of establishment. Strict measures are needed to ensure the plants do not pollute the environment via toxic by-products.
