Big Hanna Helps Protect Uganda’s Biodiversity

East Africa’s Rift system is home to some of the world’s most complex and beautiful natural ecosystems. It extends from Lake Albert to Lake Tanganyiaka, straddling Uganda. It includes 10 of Uganda’s 22 national parks, and is home to mammals, birds and fish not seen anywhere else.

The wildlife areas are home to to lions, leopards, bohor reedbuck, the giant forest hog and warthog, hippopotamus, waterbuck, the African jackal. Bushbuck and elephant abound. Open waters provide a unique ecosystem for animal life. Hippopotamus, crocodiles and sitatunga commonly occur in the Rift’s estuarine and delta swamps.

This African biodiversity hotspot also includes an oil-rich geological structure called the Albertine Grabben. The Ugandan Government is now overseeing prospecting and development of the Grabben’s oil riches while at the same time attempting to protect the livelihoods and homes of the people, animals and plants that call it home.

 

Big Hanna is now in service at two prospecting camps operated by Tullow Uganda Operations Pty in the Albertine Grabben. Each camp houses 200 people, each producing 2 kg of food waste each day through the canteens. Until recently this food waste was landfilled onsite, producing leachate with potential to contaminate nearby groundwater. In addition hazardous methane was generated, creating a potential fire hazard. Tullow Oil sought a better solution.

A feasibility study considered available technologies, economics, and environmental considerations, quantities and recommended Big Hanna in-vessel composting. Each camp, one at Kisinja and another at Buliisa, is now composting all food waste onsite with a Big Hanna T240 Composter equipped with a Big Hanna Biofilter.

Each canteen is also fitted with a Big Hanna Macerator-Dewaterer to reduce the food waste mass by 50% before composting – this makes the whole system more efficient.

Ugandan company NLS Waste undertook the installation and commissioning at both camps in one week, followed by onsite training from Big Hanna’s Cecilia Ek.

We hope that any development of this rich and beautiful area can be done sensitively, safely and carefully and we’re glad that Big Hanna can help.
