Reverse logistics framework for PET bottles

Abstract

Abstract: Reverse logistics (RL) is an engineering strategy used by manufacturing companies to develop environmental sustainability through recycling. The result of not having appropriate legislation and frameworks in Zambia, specific to RL for plastic bottles, huge volumes of Polyethylene Terephthalate (PET) bottles are dumped on the Environment. Only 30% of the waste generated, in Zambia, is collected for disposal in dumpsites and the remaining 70% is not recovered. Of the 30% waste collected, there is no data to indicate the exact amount of PET bottles disposed. This paper focuses on analyzing RL activities performed by beverage manufacturing companies in conjunction with community involvement. Examining the regulations set by the regulatory bodies in monitoring waste management issues. Three separate questionnaires are issued, one for the beverage companies, one for the regulatory body and one for the municipality. Structured interviews and direct observations were also used. The results indicate that, RL of PET bottles is not practiced by the beverage companies. However the companies recognize the importance of recycling PET plastic bottles and have printed symbols of recycling on their bottles. Measures taken to protect the environment indicate regulations from the regulatory body are in place though not effectively enforced on PET plastic waste This paper focuses on analyzing the data collected via the three tier questionnaires and providing some insights into options to implement RL, within the Zambian constraints. A Container Deposit logistics Refund Legislation (CDRL) framework was developed and proposed for use in the recovery of PET bottles and any other recyclables
