Biodigesters can treat biodegradable waste streams in a way that benefits not only the local environment, but also the wider environment by reducing the release of greenhouse gases.  Biodigesters additionally generate gas that can be used for cooking, drying, lighting and even electrical power generation in some cases.  A liquid effluent is also produced as a result of the biodigestion process which can be rich in nutrients and used to either produce high-quality compost or irrigate crops directly.

As waste-to-energy systems go, Fullwell Transform believes biodigesters hold one of the largest potential solutions to the treatment of waste streams and generation of renewable energy sources.  As such Fullwell Transform is in the process of expanding its work in this area, in new geographies and in new agri-sectors, including in partnership with researchers and academic institutions.



Pig farms

Designing, monitoring and providing oversight and quality control to pilot biodigester installations for small and medium scale animal farms, including site assessments and liaison with beneficiaries and final-users.  The work is funded by Côte d’Ivoire’s Interbranch Fund for Funding and Agricultural Advice (FIRCA).

Fullwell Transform is also conducting a feasibility analysis for further installations including evaluation and recommendations for appropriate uses of biogas and liquid effluent management, including an economic viability analysis.

Coconut processing

Provided advice on biodigester options for coconut processing.

Wet processing of coffee (2014 – 15)

Provided advice on biodigester options for the wet processing of coffee.

Mango processing
(2012 – 2014)

Partnered with Kingdom Biogas (David Fulford), Govinda Devkota and Max Appliances to pilot a biodigester system that was capable of using all mango waste streams from African mango drying SMEs that are so prevalent in West Africa.

This included a urinal for male and female workers from the neighbouring agri-processing businesses and a pre-digestion tank, which both fed the biodigester to maximise gas output.

Gas was used to cook meals for workers, provide exterior lighting to the business and even dry mangoes.  Liquid effluent was used to produce a high-quality compost that was further enriched using the vermi-composting technique, and was provided to some of the related mango drying SME’s supplier farmers for domestic use creating a closed loop.
