A Short-Term Model for End-of-Life Vehicle Recycling Planning
نویسنده
چکیده
The treatment of End-of-Life Vehicles (ELVs) and the environmental impact of discarding the resulting residues are subjects of worldwide concern. Automobile Shredder Residue (ASR) is the waste generated during the vehicle hulk shredding process, and its efficient processing represents a major concern, especially in Japan. This paper focuses on the ASR recycling process in the Japanese legislative environment. It presents a short-term ASR recycling planning problem for Japanese vehicle recyclers. The problem is formulated as a linear program, which provides optimal storage, processing, recycling and landfill disposal route decisions. The proposed short-term model for ELV recycling planning has been applied to a numerical case study in which two legislative cases of the Law on Recycling of ELVs (ELV Law) were examined. Presented numerical study demonstrated the potentials and applicability of the proposed model. The success of the final phase of implementation of the ELV Law is not jeopardised, because even the future ASR recycling quota was reached. Quantity of land-filled wastes will be radically reduced after fiscal year 2015. The ELV Law influences neither quantity of ASR collected by automakers nor vehicle hulks purchasing planning. The proposed model can help all corresponding stakeholders, especially shredding companies and automakers to improve their eco-efficiency and profitability.
