Zimbabwe turns to biogas
In Zimbabwe, electricity shortages have led to severe power cuts harming industrial activities, and the rate of deforestation has been accelerated as more people resort to firewood as an alternative source of fuel.
As a result, stakeholders in the energy sector are looking into alternative energy sources like a methane gas project in Lupane, ethanol project in Chiredzi and widespread biogas plants.
Urban areas have been seriously affected by energy challenges and yet these areas have the potential of producing large amounts of biogas as they have the feedstock for biogas plants in the form of sewage.
Biogas is produced by anaerobic digestion or fermentation of organic matter such as manure, sewage sludge, municipal waste, or bio-degradable waste.
With the big sewage treatment plants in the country, especially in large cities like Harare, the production of biogas becomes a more viable project, which the city council and the private sector can invest in.
Firle Sewer Works in the capital has the capacity to produce about 97,000 m3 of biogas in three hours.
Leslie Gwindi, the spokesperson for the City of Harare, said there is need for financing the biogas project in the city as the council is facing financial challenges to resuscitate the project.
Currently, the Ministry of Energy and Power Development has revived the projects and over 400 plants have been constructed at homestead level in Wedza, Sanyati, Chirumanzu, Gutu and Chipinge.
