FREETOWN, SIERRA LEONE — As the conflict in the Middle East continues to disrupt global energy markets, Sierra Leonean entrepreneur Andrew Sahr Norma is leading a sustainable revolution. His company, Greentech Bioenergy, is sourcing local food waste and converting it into affordable, clean biogas, providing a vital alternative to increasingly expensive Liquefied Petroleum Gas (LPG).
Geopolitical tensions and disruptions in the Strait of Hormuz have driven up LPG prices in Sierra Leone, contributing to a 40 per cent rise in the cost of living. In response, Norma’s innovative biodigester systems offer households and restaurants complete energy independence. By collecting, crushing, and processing organic waste, Greentech Bioenergy produces cooking gas and electricity at a single upfront cost.
“Our biodigester helps houses to be energy independent,” says Norma. “You don’t have to depend on the Middle East when you can use your own waste to produce cooking energy and power your devices.”
The impact is more than just economic; it is a matter of public health. With LPG becoming a luxury, many families have reverted to traditional firewood and charcoal. Martha Koroma, a cook at the Tacugama Chimpanzee Sanctuary, describes the physical toll of these methods: “Cooking with firewood disturbs our eyes and affects us. Sometimes at night, I can’t sleep. But since they installed this biodigester, it is really, really good.”
Whereas the existing government of Sierra Leone might have temporarily introduced fuel subsidies to alleviate economic pressures on the population, the answer can only come from local ingenuity. Greentech Bioenergy will fill that energy vacuum, thereby safeguarding the nation’s basic needs from external pressures.
In creating an alternative energy source from environmental waste, Andrew Sahr Norma is doing more than cooking; he is securing Sierra Leone’s future.
