E-waste crushing and sorting production line

Small Appliances & E-Waste Processing

E-Waste Recycling

Targeting small home appliances, electronic appliances, circuit boards, wires, and mixed electrical waste, building a closed-loop process of "collection, pre-disassembly, crushing, sorting, deep resource recovery, and environmental disposal" to transform complex e-waste into reusable metals, plastics, and high-value resources.

INDUSTRY CHALLENGES

Core Pain Points of Small Appliance and E-Waste Processing

Fragmented Collection System

Insufficient integration of online and offline channels, low coverage of community recycling points, "difficult collection, chaotic pricing" remains prominent, affecting the efficiency of standardized collection entry points.

Weak Refined Processing Capability

SMEs largely remain at the "rough disassembly, material selling" stage, with room for improvement in recovery rates of precious metals, high-end plastics, and high-value components in circuit boards.

High Environmental Compliance Costs

Strict requirements for closed-loop treatment of wastewater, exhaust gas, and solid waste; investments in hazardous waste temporary storage, dust control, and VOCs treatment impose continuous pressure on SMEs.

Technology and Equipment Gap

High-end intelligent disassembly, AI sorting, and multi-material precise identification equipment require high stability and precision; domestically manufactured equipment needs continuous improvement through system integration.

PROCESS

Closed-Loop Process from Collection to Finished Product Storage

01

Collection

Collection through "internet + recycling," community recycling cabinets, home appliance stores, and brand trade-in programs, with data erasure and privacy protection completed before entering processing.

02

Temporary Storage and Transfer

Classified temporary storage by small appliances, mixed electrical waste, wires, circuit boards, and hazardous components, establishing inbound records and traceable material flows.

03

Pre-Disassembly

Manual and intelligent equipment collaboration, first removing batteries, displays, compressors, Freon tanks, and other hazardous or high-value components to reduce downstream crushing risks.

04

Coarse and Fine Crushing

Dual-shaft shredders shear whole units into 50-100mm coarse material, then hammer or vertical crushers finely crush to 10-30mm, achieving separation of plastics, metals, and circuit boards.

05

Multi-Stage Sorting

Through Z-type air classification, magnetic separation, eddy current separation, vibrating screening, electrostatic separation, color sorting, and hyperspectral AI sorting, separating iron, non-ferrous metals, plastics, and PCB materials.

06

Deep Resource Recovery

Copper and aluminum smelting and purification, iron re-melting, plastic washing, drying, color sorting, and pelletizing, circuit boards crushed and ground for precious metal extraction.

07

Environmental Disposal

Wastewater treated through sedimentation, reverse osmosis, and reclaimed water reuse; exhaust gas treated through activated carbon adsorption and catalytic combustion; residues and hazardous waste disposed in closed loop per qualification requirements.
