An Experimental Approach Towards Sustainable Solution for Material Recycling of ELV Plastic Bumpers and EV Batteries 2024-26-0164

A general automotive car is majorly composed of high strength steel (6%), other steel (50%), Iron (15%), Plastics (7%), Aluminum (4%) and others (Rubber, Glass, Textile) about 18%. End-of-life vehicles (ELVs) are a significant source of waste and pollution in the automotive industry.
Recycling ELVs, particularly their plastic components, Li-ion batteries, catalytic converters, and critical technology components such as alternators, semi-conductor chips, and high tensile strength steel can reduce their environmental impact and conserve valuable raw materials. The paper conducts a SWOT analysis and a life cycle assessment (LCA) to evaluate the long-term viability and potential of ELV recycling, environmental impact, and carbon footprint.
This paper examines the current state and challenges of ELV recycling in India and proposes a sustainable recycling solution for waste bumpers that includes paint removal, modification, reprocessing & recovery of precious metals from xEV Li-ion batteries.
  1. i
    Plastic recycling – Mainly PP from bumpers and other components.
  2. ii
    Precious metals recovery – Lithium, Cobalt, Nickel, Mn etc.
Based on pilot line experiment sustainable recycling solution was established and validated through lab testing to compare the changes in physical properties.
The paper also discusses the progress and challenges of achieving Carbon neutrality and circular economy objectives in the automotive industry and provides insights on sustainable material developments like e.g., long cellulose fiber reinforced thermoplastic for bumpers, reusability of raw materials in automobile parts manufacturing without compromising on quality requirements & provides data for rational decision-making and policy-making for ELV recycling in India.
