Abstract
The goal of this study is a qualitative and quantitative evaluation of processes and flows within the solid waste management (WM) system in Kutaisi, Georgia, and the wider Imereti region. The applied methodology based upon data collected through customized questionnaires enabled both the formal and informal sectors (IS) to be characterized. Moreover, waste composition studies in the region’s rural and semi-urban areas revealed that the share of recyclables is higher in urban areas and commercial centres. A material flow analysis was used to transparently consolidate the collected data, showing that dumping and landfilling still play a major role within the Georgian WM system. The total amount of waste landfilled on ‘Nikea’ landfill in 2019 equals 58,000 tonnes year−1, from where around 55,500 tonnes year−1 is formally collected municipal solid waste, and 2,503 tonnes year−1 is commercial and industrial waste. According to the findings, the size of the IS in Kutaisi is 0.07–0.15% of the city’s population, whose supposed cumulative income is estimated GEL 0.57–1.13 million (EUR 180–360 thousand) in 2019. Informally collected recyclables are estimated 870–1,750 tonnes year−1, comprising 6–11% of recyclables landfilled in Kutaisi in 2019. The study provides a basis for decision-makers. Replicating the applied methodologies and approaches to create this sound database could support the WM system across whole Georgia. The study further reveals the importance of the need to stop neglecting the IS and recognizes the importance of its role in the WM system of Kutaisi and the wider Imereti region, respectively.
