The oil filter assembly, as a consumable item in automobiles, if not properly disposed of after replacement, can cause pollution to soil and water sources, as well as waste of recyclable resources. Therefore, following scientific recycling standards to achieve the resource utilization and harmless treatment of waste assemblies is an important measure to practice environmental protection concepts and respond to green development. It is also the responsibility of car owners and maintenance institutions.

The recycling of waste assemblies must follow the principle of classified recycling and cannot be mixed with ordinary household waste. They should be handed over to qualified waste automotive parts recycling institutions, repair shops, or environmental protection treatment enterprises for centralized recycling. Before recycling, pre-treatment should be done to completely drain the residual oil in the waste assembly to avoid oil leakage and environmental pollution; Simultaneously remove impurities and dirt from the surface of the assembly, providing convenience for subsequent processing.

The professional processing flow mainly includes three steps: disassembly, separation, and reuse: first, disassemble the waste assembly, separate the shell, filter element, sealing ring, spring and other components; If the shell is made of metal material, it can be recycled and processed after cleaning and rust removal to make other metal components; Engineering plastic shells can be classified and crushed for recycling, improving resource utilization efficiency. The filter element needs to be treated harmlessly due to its adsorption of a large amount of waste engine oil and impurities. Some of the waste engine oil can be extracted through professional processes, and the residue can be solidified and disposed of in compliance with standards.

Ordinary car owners should establish a standardized recycling awareness, and when replacing assemblies, hand over waste products to repair shops for unified recycling, and do not dispose of them casually; Repair institutions need to establish a ledger for the recycling of waste assemblies and coordinate with legitimate processing enterprises to ensure that each batch of waste assemblies can be processed in compliance, jointly promoting the green development of the automotive aftermarket.
