Abstract
The Base line information on solid waste generation rate of town helps as tool for proper management of solid wastes. The absence of data on the quantity of plastic waste generation rate at household level is one of the reasons for poor plastic waste management in BahirDar town. Plastic bag waste generation rate analysis is an essential input for planning solid waste management services for proper management of plastic waste. The aim of this study was 1) to identify plastic bag waste generation per capita per day, 2) to determine the role of socio- economic levels in household plastic bag generation rate, 3) to determine the proportion of plastic bag waste in plastic waste stream 4)to identify the underlying causes and associated undesirable impact of plastic bag waste disposal on the environment and indicating possible solid waste management options. To determine the number of households that should be analyzed, the proportionality that derived from domestic waste variable was used. Sample size of 105 housing units was obtained by using sample size determination formula and taking 10% contingency for non-voluntary respondents. After determining the required numbers of households, socio-economic and plastic waste data collections were carried out in 105 randomly selected households for three consecutive weeks. The result showed that on average 0.35gm/capita/ day and 1.73gm/households/day of plastic bag waste was generated from the households. The result obtained indicated that there is a significant mean variation between different income groups. Plastic bag waste generation rate is higher for poor than lower, middle and high-income groups. However, there is no significance difference between in plastic bag waste generation among lower, middle and high-income groups. In plastic waste stream, plastic bag waste constitutes a large proportion, which accounts 92% by weight and 89.4% by volume. On other hand, packing plastic materials accounts 8% by weight and 10.6% by volume. The total plastic bag waste generated from the town was estimated to be 24.87 ton per year. This is more than 12 million plastic bags per year that eventually enters to the environment. More over, plastic bag waste generated was disposed off inappropriately. This problem was attributed by poor plastic waste management systems, single-use disposal nature of the product and its low cost, failure of institution and individuals to collect and dispose plastic bags properly, absence of recycling activity in the town and low public awareness on its management. Generally, plastic bag waste in the town is acute problem, where waste management practice is very poor and it needs immediate solution to combat the threats of plastic bag waste. Thus, rising of public awareness on sustainable use and management of plastic bag waste is essential. There fore, it needs to promote for use of traditional bags such as‘zenbel’, reusing and recycling of plastic bags in order to minimize plastic bag waste. In addition, the government should put a tax or ban on single-use disposable plastic bag products.
