E-waste crushing and sorting production line

Small Appliance & E-Waste Processing

E-Waste Recycling

For small household appliances, electronic devices, circuit boards, wires, and mixed electronic waste, we construct a closed-loop process of "collection, pre-dismantling, 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 in Small Appliance and E-Waste Processing

Fragmented Collection System

Insufficient integration of online and offline channels, low community collection point coverage, and persistent issues of "difficult collection and chaotic pricing" continue to hinder standardized collection intake efficiency.

Weak Refined Processing Capability

Most small and medium-sized enterprises remain at the "rough dismantling and 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, along with hazardous waste interim storage, dust control, and VOCs treatment, impose sustained pressure on small and medium-sized enterprises.

Significant Technology and Equipment Gaps

High-end intelligent dismantling, AI sorting, and multi-material precision identification equipment demand high stability and accuracy. Domestically manufactured equipment requires continuous improvement through system integration.

PROCESS

Closed-Loop Process from Collection to Finished Product Storage

01

Collection

Collection is completed through "Internet+ recycling," community recycling cabinets, appliance retail stores, and brand trade-in programs. Data wiping and privacy protection are completed before materials enter processing.

02

Temporary Storage and Transfer

Materials are classified and temporarily stored by category: small appliances, mixed electronic waste, wires, circuit boards, and hazardous waste components. Inbound ledgers and traceable material flows are established.

03

Pre-Dismantling

Manual labor and intelligent equipment work in coordination to first remove hazardous or high-value components such as batteries, displays, compressors, and Freon canisters, reducing downstream crushing risks.

04

Coarse and Fine Crushing

A dual-shaft shredder shears complete appliances into 50-100mm coarse material, which is then finely crushed to 10-30mm by a hammer or vertical crusher, achieving liberation of plastics, metals, and circuit boards.

05

Multi-Stage Sorting

Through Z-type air separation, magnetic separation, eddy current separation, vibratory screening, electrostatic separation, color sorting, and hyperspectral AI sorting, ferrous metals, non-ferrous metals, plastics, and PCB materials are separated.

06

Deep Resource Recovery

Copper and aluminum are smelted and refined, iron is returned to furnaces for remelting, plastics undergo washing, drying, color sorting, and pelletizing, and circuit boards are crushed and milled before precious metal extraction.

07

Environmental Disposal

Wastewater undergoes sedimentation, reverse osmosis, and reclaimed water reuse. Exhaust gas is treated through activated carbon adsorption and catalytic combustion. Residues and hazardous waste are disposed of in a closed loop per qualification requirements.
