Ashaiman turns waste into commercial fertiliser

A waste treatment plant that can produce about 500 tonnes of fertiliser per year, and can generate about 580,000 kWh of electricity per year from the biogas produced during the process.

The African Water Facility (AWF) signed a €1 million grant in favour of an NGO Training, Research and Networking for Development (TREND) to support an innovative sanitation scheme.

The project, which is a tripartite collaboration among TREND, Safi Sana Ghana Limited, and the Ashaiman Municipal Assembly, is designed to turn waste into bio-fertiliser and energy whilst providing affordable and sustainable sanitation services for the non-sewered urban poor communities of the Ashaiman district of Accra.

Specifically, the AWF grant will finance the construction of a waste treatment plant that can produce about 500 tonnes of fertiliser per year, and can generate about 580,000 kWh of electricity per year from the biogas produced during the process.

The project will also contribute to improving the hygiene, health and quality of life for an estimated 125,000 underprivileged urban dwellers by providing them access to new, safe, sanitation services through the expansion of the Ashaiman Municipality’s sanitation coverage.

“The African Water Facility supports resource recovery projects because it has been shown to solve so many problems at once, especially where resources are scarce and access to affordable fertilisers and energy is low,” said Akissa Bahri, Coordinator of the African Water Facility.

“While resource recovery systems help minimise environmental pollution, waste converted and sold as fertiliser provides much-needed affordable soil nutrients for farmers and families; and used as biogas, is a safer, cleaner and more affordable source of energy for more economically disadvantaged communities; it’s a clear win-win for the urban poor, the private sector and the environment.”

Marie-Laure Akin-Olugbade, Resident Representative of the African Development Bank in Ghana, underscored the Bank’s commitment to promoting innovative interventions and renewable energy in Africa. She invited all stakeholders to support the project’s tripartite arrangements to ensure its successful implementation for the realisation of project outcome and potential replication in other municipalities in Ghana and beyond.

It is anticipated that the project will contribute to increasing private sector investments in the sanitation sub-sector, and to boosting business and economic development by promoting attractive, replicable business models for improved sanitation service delivery. With ever-dwindling natural resources and increasing oil and food prices, thinking innovatively is inevitable -- and turning waste to bio-fertiliser and energy is poised to be very profitable business.

The project’s innovative aspects include:

• The recovery of energy and nutrients from faecal and organic waste;

• The establishment of market opportunities for the sale of products derived from waste;

• The involvement of the private sector in the sanitation business and the generation of income for all operators and their staff as part of the service supply chain: from waste collection to transport, treatment and reuse;

• The opportunity to demonstrate how Ghana’s new energy bill can be implemented through small strategic investment projects with participation of the private sector and civil society;

• The promotion of improved sanitation services and hygiene behavior-change.
