Biogas ever more popular in rural Botswana due to UNDP project

At a cattle post settlement called Gatuma located near Mmathethe village, south of Botswana, Goemeone and Mpho Kagiso have over the past year embraced biogas energy and are enjoying more than just the financial relief it brings, reported Xinhua,
"Biogas has changed our lives a lot. When it is raining and its windy, we can cook and don't go to bed hungry. We also warm up water for bathing," says Goemeone Kagiso, whose life is centred around livestock rearing and crop farming.
He and his wife own 15 cattle, five pigs and a wide range of poultry. From these he collects between five to 40 litres of waste a day that he feeds into his 10m3 biogas digester.
Kagiso is one of the 231 beneficiaries of the Botswana biogas project which was largely made possible by funding from the Global Environment Facility and the United Nations Development Programme (UNDP) with the objective of promoting the production and use of biogas as an environmentally friendly source of energy for farms, households and institutions that produce or have access to agro-waste.
The initial aim of the project - that launched on 20 January 2017 and was completed in January 2022 - was to construct 1,000 small-scale digesters but this target was reduced to at least 200 due to time constraints.
According to the project's final report, 110 small-scale digesters had been installed and the majority of them were operational by mid-2021, with an estimated 80m3 per day of biogas produced.
Tumisang Ruda, an energy engineer at the Department of Energy of Botswana, said the beneficiaries of the biogas project are spread within the Kweneng, Kgatleng, Southern and South East districts. These districts cover less than 25 percent of the country's landmass, yet their main landfill sites contributed almost half of the total municipal solid waste collected by landfill in 2017, according to Statistics Botswana.
To become a beneficiary, Goemeone Kagiso and his wife had to apply and invest P3,500 (271 US dollars) towards buying construction materials for the digester. The implementing organisations covered labour expenses.
Kutlo Sedimo, 29, another beneficiary of the project said he spent P40,000 (3,096 US dollars) on materials needed for the installation of a 30m3 digester that was completed in May last year in Matlagatse, a farming settlement near Molepolole village, about 50 kilometers west of Gaborone.
"It's expensive but a good investment, having access to energy makes life easy and you invest once, it's better than buying electricity and gas every month," Sedimo noted.
What he feeds his digester is mainly cow dung from his family's 75 cattle. "The best time to collect cow dung is early morning before they leave for grazing," he explains, encouraging other citizens to use biogas as it also gives slurry, a fertilizer byproduct rich in nitrogen that would be good for their crops.
There were only 15 biogas digesters in the country when the biogas digester project was first rolled out. The increase by 231 biogas digesters shows that biogas is fast becoming popular in rural households that are not connected to the national electricity grid.
The UNDP final project report, on the other hand, suggests that the project implementers could have built more had it not been for the fact that some farmers were too poor to invest in the biogas digester construction materials.
"I encourage farmers to start using biogas, it will help them a lot and transform their lives," Kagiso said.
