Assessment of plastic waste management in the reverse logistics network of Kampala District: a case study of Kawempe division
MetadataShow full item record
Globally plastic production is 300 tons per year. This makes it 9.1 billion tons of plastics yet only 9% of has been recycled, 3 to 8 million tons of plastics are dumped into water bodies per year. This is because reverse logistics of other waste like metal scrap has over time been given attention other than plastic waste. The main purpose of the study was assessing plastic waste management in the reverse logistics network of Kampala district with a specific focus on Kawempe division. The objectives of the study were to categorize and quantify different types of plastic in the reverse chain network, the recycling potential of all plastics and establish the effective recommendations for proper plastic waste management in the reverse logistic chain network. A questionnaire was used to collect information on categories, quantities and the recycling potential of plastics in the reverse logistic chain network and a survey, interviews were done to establish effective recommendations for proper plastic waste management in the reverse logistic chain network.72.5% is PET, 52.5% HDPE, 45% LDPE, 40% PP, 32.5% PE and 20% is PS were the categories that dominated the chain network.85% of the plastic collectors collect between 5-30 kilograms of plastics in a day, followed by 72.5% who collect between 31-70 kilograms of plastics in a day, 47.5% collect between 71-150 kilograms of plastics in a day and 22.5 collect between over 150 kilograms of plastics in a day. Approximately 57% of plastics in the chain network are recycled up to 100%, 42% are un recyclable which is mainly PS, PP. This is mainly because recycling lines for PET, PS, PP, are very expensive to buy thus most recycling factories have not installed them. There is need for information linkage between plastic collectors, transporters, recyclers and all stake holders in the waste management to ensure proper plastic waste management practices, measures to educate all the stakeholders about PPE and make sure that they are followed according the rule of law. Incentives should be accorded to recycling factories to acquire more and advanced recycling lines for PP, PS, and PET. Equally all plastic manufacturing factories should by mandate according to the law install in their factories the recycling lines for the products they manufacture in order to increase on the recycling potential of all plastics.
