Biogas adoption helps reducing environmental degradation

By Lisa Masuku

The adoption of biogas by education institutions has been described as major step towards the easing of deforestation and greenhouse gas emissions in the country.

Having adopted the use of biogas energy in 2018, Solusi Adventist High School in Bulilima district, Matabeleland South is now playing an active role in the fight against climate change.

The biogas plant, a renewable energy source which uses biodegradable waste such as cow dung and food waste to generate energy.

Bulilima resident Mr Mandla Dube, said the biogas plant has helped reduce deforestation in their area.

The environmentally friendly energy plant has also taught students to be environmentally conscious and to play an effective role in preventing pollution.

“This project has taught us a lot. Nothing goes to waste. We do not just throw away our left-over food. We use that very food to fuel our biogas plant. The water which is then produced as waste by the biogas is then used for watering the garden,” Solusi Adventist High School student, Nyasha Gakanji said.

The Minister of State for Presidential Affairs and Monitoring Implementation of Government Programmes, Dr Joram Gumbo assessed the school’s biogas plant this Thursday, saying it is key in driving the nation towards the realisation of its developmental goals.

“It is our expectation that the programme will lead to the realisation of developmental goals as set out in the National Development Strategy and subsequently the attainment of Vision 2030,” he said.

The biogas project is an ideal renewable energy source as it is a cheap option for low-income communities.

“In Zimbabwe, renewable energy is an ideal alternative as it is an affordable option for low-income communities,” said Honourable Abednico Ncube, the Minister of State for Matabeleland South Provincial Affairs and Devolution.

Biogas mainly consists of methane and is produced through fermentation of organic materials such as cow dung or food waste and a biogas digester comprises an inlet chamber, main dome expansion chamber and slurry outlet for liquid waste.
