Ghana is preparing to implement a waste source-separation and composting project in the Accra Metropolitan Assembly, with financing, implementation support and monitoring from the African Development Bank Group.
The Accra Metropolitan Assembly Waste Source Separation and Composting Project is intended to improve how municipal waste is sorted and managed before it reaches disposal sites. Project documentation published by the African Development Bank includes environmental and social assessments, a resettlement and livelihood restoration plan, and a stakeholder engagement plan.
Source separation is only the first step
Separating organic waste, plastics, paper, metals and other materials at source can reduce contamination and improve the amount of waste available for recycling or composting. But the success of such a system depends on every stage of the chain working together.
Households and businesses need clear guidance and appropriate containers. Collection operators must keep separated materials apart during transport. Sorting and composting facilities need reliable operating capacity, while recovered materials require buyers if the system is to remain financially viable.
Without those links, source separation can become an additional collection requirement without delivering meaningful reductions in landfill use or improvements in urban sanitation.
Building a market around recovered waste
The commercial side of the project will be as important as its environmental objectives. Composting requires demand from farmers, landscapers and other users. Recyclable materials need stable off-take arrangements, quality standards and pricing that can support collection and processing costs.
Accra’s informal waste workers also form an important part of the existing recovery economy. Implementation will need to account for livelihoods, occupational safety and the role of informal collectors in any more formalised system.
The governance test
Municipal waste projects often face challenges involving public participation, enforcement, operating finance and coordination between government agencies and private contractors. Long-term success will therefore depend on more than infrastructure spending.
Clear accountability for collection performance, transparent procurement, reliable maintenance and public reporting will be necessary to ensure that the project produces lasting improvements.
For Accra, the opportunity is to move beyond waste disposal towards a circular system in which organic and recyclable materials are treated as economic inputs. Whether the project achieves that will depend on its ability to connect household behaviour, municipal operations, processing infrastructure and functioning markets.
