Waste cable and wire recycling is a task that combines environmental benefits with the value of resource recycling. It not only reduces the pollution caused by discarded cables (such as plastic sheaths, heavy metals, etc.), but also recovers precious metals like copper and aluminum, as well as recyclable materials such as plastic and rubber. The following provides a detailed introduction to cable and wire recycling knowledge from five dimensions: the recycling process, material classification, recycling methods, precautions, and industry significance.

The recycling of scrap wire and cable must follow the logic of "classification - disassembly - purification - reuse," with specific steps as follows:

Recycling Collection: Collecting discarded cables from various sources such as factory淘汰 lines, construction sites (leftover cables), residential areas (home renovation), and scrap recycling stations. Initially sort the cables based on "material" and "specification" (e.g., distinguishing copper-core and aluminum-core cables) to prevent mixing and ensure subsequent value.
Pre-processing (stripping / dismantling): Removing the sheath (made of plastic or rubber) from the cables through equipment or manually, separating the "metal core" from the "non-metallic sheath."
Small/Thin Wire Cables: Commonly stripped with manual/electric strippers for high efficiency and reduced metal loss.
Large / Coarse Wire Cables (such as high-voltage cables): First, cut the cables with a cable cutter or a ring cutting machine, then separate the core wire from the sheath by "hot stripping" (low-temperature heating to soften the outer skin) or "mechanical stripping."
Metal Refining and Processing:
Copper/Aluminum Core Processing: Separate and organize the copper and aluminum cores after separation, remove the surface residual skin fragments, then melt them at high temperatures in a smelting furnace, purify them, and cast them into copper ingots and aluminum ingots (purity over 99.5%), which are then reused as metal raw materials in industries such as wire and cable, hardware, etc.
Non-metallic sheath treatment: Plastic (such as PVC, PE) and rubber sheaths are processed through crushing, cleaning, and granulation to produce recycled plastic granules, which are then used in the manufacturing of new plastic pipes, injection-molded parts, etc. Rubber can be further processed into recycled rubber, suitable for making seals, soles, and more.

Finished Sales/Reutilization: Refined metal ingots, recycled plastic granules, etc., sold to cable manufacturers, metal processing plants, or plastic factories to complete the "waste - recycling - re-production" cycle.

Different types of recycled cables have varying recycling values and disposal methods; the core classifications are as follows:

III. Common Recycling Methods

Based on the recycling entity and scenario, it is primarily divided into the following 3 categories:

Individual/Family Scrap Collection
Channels: Residential waste recycling stations, mobile waste collectors (attention must be given to fair weighing to prevent "shortweight" or "underweight").
Applicable: Old electrical wires for home renovation replacement, scattered cables from disassembled household appliances (small quantity, mainly copper-core wires).
Note: The outer skin can be easily peeled off before sale (some recyclers purchase at the "with skin" price, but the per-unit price of the metal core is higher after peeling, though labor costs must be considered).
Corporate / Factory Bulk Purchase
Scene: Large quantities of waste cables generated from factory equipment upgrades and project completion, such as unused spools of cables and obsolete high-voltage cables.
Cooperation Method: Directly connect with professional recycling companies (not small recycling stations), who will visit for assessment (quote based on material, specification, and weight), and provide compliant recycling certificates (to avoid environmental risks).
Advantages: Bulk recycling offers more favorable pricing, and the recycling company can provide on-site disassembly and transportation services, reducing the company's processing costs.
Professional Recycling Platform / Online Channels
Format: Post recycling needs on platforms like "Recycling Resource Network" or "Brother Recycle," or contact the online customer service of local legitimate recycling enterprises.

Features: Transparent pricing (refer to the current copper and aluminum market prices), some platforms offer "evaluate first, then recycle" service, suitable for businesses or individuals sensitive to recycling prices and seeking compliance.
