Renewable Energy

For

Sub-Sharan Africa

Green Heat generates biofuel, a form of alternative energy, which tackles waste management at source. We convert waste into energy to reduce the reliance on non-sustainable biomass and mitigate deforestation. Our mission is to improve clean energy access, leading Africa into it’s green energy future.

Energy Issues in Sub-Saharan Africa

Deforestation
Air Quality
Energy Access
Waste Management

Wood fuel dependency is causing rapid deforestation across Sub-Saharan Africa.

Uganda is one of the worst affected countries, having lost 60% of national forest cover in the past 25 years.

Every year four million people die globally from household air pollution.

Fatal respiratory diseases in women and children account for the majority of deaths, brought about through unsafe, poorly ventilated cooking practices. Cooking is the fourth biggest killer in the world; taking more lives than Aids, Malaria and TB combined.

Over 60% of sub-Saharan Africans are without access to electricity.

Cooking and heating needs are met using traditional stoves, mostly utilising unsustainable sources of biomass e.g. wood fuel, crop residues, cow dung and charcoal. This accounts to over 90% of the region's total energy consumption.

Waste is left uncollected all over sub-Saharan Africa.

The untreated rubbish contaminates groundwater resulting in environmental and public health issues. The net result is a rising cost of waste management, stalling the region’s development.

Why We

Do It

Green Heat is committed to reducing deforestation and waste pollution.

  • Our clean energy solutions decrease national reliance on unsustainable biomass.
  • We aim to raise awareness in the political, economic and social framework of Uganda's energy sector.

Our systems are designed with consideration.

  • We bring people together by the collective financial gain associated with re-using waste products.
  • Green Heat employs locally to facilitate the development of Ugandan nationals.

Green Heat believes in empowering women for national development.

  • We provide all-women farmer groups with charring kilns to generate a source of income by converting waste into a commodity.
  • Our female sales representatives gain financial independence through distributing our sustainable briquettes.

Who We Work With

Education
Agriculture
Residential
Commercial

We have partnered with the Ugandan Ministry of Energy to provide sustainable energy solutions in schools.

In 2014 we constructed 10 bio-latrines to reduce reliance on wood fuel. Following the project’s success, Green Heat has been commissioned to construct a further 10 bio-latrines in 2015. For one of our largest projects to date, we installed a 120m3 digester for the National Teachers College in Kaliro, Uganda.

Our projects range from supporting small scale farmers to waste management on an industrial scale.

We are currently installing solar powered slurry separation systems for farms in East Africa. Our recent USAID grant from Securing Water for Food is financing technology to decrease water demands and enhance the production of organic fertiliser.

Green Heat is committed to improving energy resources in African homes.

We have installed over 150 domestic biogas digesters and 40 kilns for briquette production. We are also expanding our access to finance schemes in order to increase the distribution of solar lamps.

Green Heat works with businesses to offset carbon and give back to local communities.

This year we had the pleasure of working with Walt Disney Studios, during their filming of Queen of Katwe. We won the design bid to construct a large-scale bio-digester for the new school they have funded in the Namuwongo slum of Kampala.

Who We Are

Managing Director
Operations Director

Vianney Tumwesige

Vianney started Green Heat from its grass roots origins in 2006. His entrepreneurial drive combined with innovative approaches has lead to the company’s success today.

By compressively designing and delivering waste management systems, Vianney has gained an array of technical and project management experiences. Driven by his passion for renewable energy, Vianney’s AFRI-FLAME research into improving the efficiency of biogas digesters and biomass stoves, shall soon earn him a PhD from The University of Aberdeen.

Gabriel Okello

Gabriel has a leading role within Green Heat, implementing biogas installation, environmental consultancy and briquette manufacturing.

His interests are in occupational hygiene, household air pollution and waste management. He has pioneered bio-latrine digesters in schools for Uganda’s Ministry of Energy. He has delivered biogas digesters under the AFRI-FLAME project and set up numerous briquette kilns and clean cook stoves across sub-Saharan Africa.

Gabriel is also conducting research on human exposure issues associated with burning conventional biomass under the BREATHE-Africa partnership, a research piece that shall earn him a PhD from The University of Aberdeen. Additionally, Gabriel is leading the implementation of the innovative Solid-Liquid separation technology, which will help farmers save water and grow more food.

His experience in environmental chemistry and renewable energy research has enabled him to collaborate with NGO’s, government departments and multinational companies for the advancement of renewable energy in Sub-Saharan Africa.
