He also stressed the need for investment in infrastructure for locally appropriate and low-cost composting and anaerobic digestion, to divert putrescible organics from landfill sites to further reduce the GHG emission resulting from the current solid waste disposal practices.

Mr Solomon Noi, the Director of Waste Management, at the AMA in a remark said the main goal of the project among others was to support the city to bridge the baseline data gap in solid waste management, develop and design targeted climate change action policies and programmes, identify suitable treatment technologies. 

He acknowledged the importance of the study and observed that the city was equipped with the relevant scientific data on how best to deal with waste management issues. 

"So in a nutshell at least, for now, we can be firm to say that we have some baseline data on the properties of municipal solid waste for the GAMA, which we can rely on since it had been validated here by stakeholders from academia, industry and municipalities. This will support managing authorities and policymakers towards informed decision making in the modernisation of the city’s solid waste management system, " he said.

The Greater Accra Metropolitan Area (GAMA) lies along the South-Eastern coast of Ghana and covers an area of 1453.53 km2.  It consists of 25 municipalities and it is home to the capital city (Accra) and the industrial hub (Tema) of the country.
