Home Appliance & WEEE Recycling
Connect appliance dismantling and metal recovery with crushing, washing and density separation of prepared plastic fractions. Configure the process for waste refrigerators and freezers, end-of-life washing machines, air conditioner housings and dismantled WEEE plastics.
An appliance dismantling system and a plastics washing system handle different feeds. Connect both stages for a complete project, or add the washing section to an existing dismantling facility.
| Incoming Material | Required Front End | Next Processing Stage |
|---|---|---|
| Whole household appliances | Inspection, manual dismantling and removal of hazardous components; refrigerant and oil recovery for cooling appliances | Controlled shredding and metal, foam and plastic separation |
| Depolluted appliance cabinets and assemblies | Check residual components and select the liberation process; insulated cabinets need a dedicated foam and gas treatment design | Ferrous and non-ferrous recovery, followed by collection of the plastic fraction |
| Pre-separated appliance plastic scrap | Check polymer mix, metal carryover, rubber, foam and restricted additives | Crushing, friction washing, density separation, rinsing and drying |
The plastics washing section accepts prepared material. Whole untreated refrigerators, batteries, circuit boards and display assemblies need separate preparation or treatment routes.
The final equipment sequence follows the appliance mix, depollution status and intended outlets for each recovered material.
Remove designated hazardous components and recover refrigerants and compressor oil with purpose-built equipment before opening cooling circuits. Separate compressors, cables, batteries, electronics and other components for their appropriate recovery routes.
Primary shredding and secondary crushing open prepared cabinets and release attached metal, plastic and insulation. Refrigerator foam needs a contained treatment route with blowing-agent recovery and gas controls specified for the feed.
Magnetic separation recovers ferrous material. Eddy current separation targets liberated non-ferrous pieces, while air separation removes suitable light fractions. Copper and aluminum may need further sorting; foam is directed to its dedicated treatment route.
The prepared plastic fraction enters wet size reduction and friction washing to loosen dirt, oil residues, fines and surface contamination. Particle size and washing intensity are selected through feed assessment.
Water and, where justified by trials, controlled-density salt-water stages divide the material into density fractions. ABS and HIPS can overlap in density; fillers and flame retardants also change separation behavior, so resin sorting may require additional equipment.
Rinse salt-water-treated fractions, mechanically dewater and finish drying to the agreed downstream requirement. Check moisture, residual metals, polymer composition and restricted substances before compounding, pelletizing or sale.
Define the handoff from prepared appliances to separated plastic scrap. New facilities can plan both sections, while existing dismantlers can add the cleaning and separation modules they need.
Plan dedicated collection for ferrous metals, non-ferrous fractions, treated foam, plastics and residues. Material liberation and sorting determine the condition of each recovered stream.
Combine friction, density separation and rinsing around appliance-derived ABS, HIPS and PP. Additional dry sorting can be assessed where density separation alone cannot meet the output specification.
PLC sequencing, equipment interlocks and water recirculation are configured with the line. Filtration, sludge removal, rinse-water management and brine handling are sized to the actual contamination load.
Refrigerator cabinets retain insulation foam and blowing agents after the cooling circuit has been drained.
Specify foam treatment, gas recovery, containment and fire protection as part of the refrigerator process. Dust extraction and a wash tank do not replace these systems.
Metal fasteners, wiring, rubber seals and foam remain attached to plastic fragments.
Match the liberation stage to the assembly, recover metals upstream, and assess air classification or rubber separation for the remaining contamination.
Clean-looking flakes still contain mixed polymers or restricted flame-retardant additives.
Use feed screening, sample analysis and appropriate sorting. Washing removes surface contamination; it does not remove additives compounded into the plastic.
Variable dirt load and salt carryover destabilize washing and downstream processing.
Control bath density, filtration and sludge removal, then size rinsing and drying to the product target. Select wetted materials for the actual chloride concentration, temperature and water chemistry.
Module references for project planning. The final arrangement depends on your appliance mix and material trials.
After dismantling and liberation, recover metals and separate foam before sending the plastic fraction to washing. Inspect the remaining polymer mix, rubber, dirt and residual metal so the cleaning section receives a defined feed.
Friction washing and density separation address surface dirt and mixed-density material. Trial results determine bath settings, the number of stages and whether additional polymer or rubber separation is needed.
Cabinets, liners and associated plastics after depollution. Refrigerant recovery and insulation-foam treatment are defined separately from the plastic washing section.
Dismantled panels, housings and plastic parts. Motors, metal assemblies, concrete counterweights and other non-target components are removed or routed to separate recovery stages.
Prepared plastic housings from air conditioners after refrigerant recovery and separation of compressors, heat exchangers and electrical components.
Selected plastic housings from waste televisions, computers and printers after removal of batteries, circuit boards, displays and toner components. Feed screening addresses flame retardants and other restricted substances.
| Module / Parameter | Configuration Basis | To Confirm for Your Project |
|---|---|---|
| Dismantling capacity | Appliance type, condition, size and manual work content | Units/hour and incoming mass/hour for the agreed appliance mix |
| Plastic washing capacity | Prepared plastic feed, bulk density and contamination | Input kg/h and saleable output yield from representative trials |
| Size reduction and metal recovery | Part dimensions, attachments and metal content | Shredder/crusher selection, particle size, magnet and non-ferrous stages |
| Washing and density separation | Polymer composition, dirt load and target fractions | Water or salt-water stages, density settings, rinsing and additional sorting |
| Wetted construction | Water chemistry, chlorides, temperature and wear | 304 stainless steel options where suitable; confirm brine compatibility and material grade |
| Controls and utilities | PLC scope, interlocks, drying and treatment systems | Installed kW, measured energy use, water makeup, discharge and floor space |
| Refrigerator treatment package | Refrigerants, insulation and blowing-agent types | Depollution, foam treatment, gas capture and site-specific emission controls |
Final capacity, power, water demand, moisture, recovery and purity targets are agreed against a defined feed sample and acceptance method. Appliance intake capacity and plastic washing throughput are separate sizing figures.
A clear feed description lets us define the dismantling, separation and washing scope together.
Send photos or video, appliance categories, daily volume, size range and current dismantling method. State whether the feed is whole appliances, depolluted cabinets or separated plastic scrap.
Share available polymer analysis and estimates for metal, foam, rubber, dirt and moisture. Identify cooling equipment and any screening already performed for restricted additives.
Define outlets for metals, foam and plastics. Provide buyer requirements for polymer composition, moisture, residual metal and other contaminants, and agree representative sampling for trials.
Provide a layout, power supply, water and wastewater arrangements, local treatment requirements and existing equipment. Clarify who supplies depollution, gas treatment and water treatment systems.
| Planning Point | Dismantling + Separation + Washing | Prepared-Plastics Washing Section |
|---|---|---|
| Starting material | Appliances requiring inspection and preparation | Pre-separated plastic fractions with defined contamination |
| Front-end scope | Depollution interfaces, dismantling, liberation and material recovery | Feed inspection, metal protection and plastic size reduction |
| Cooling appliances | Dedicated refrigerant and foam/blowing-agent treatment scope | Accept only material prepared for the washing process |
| Main outputs | Separate metal, treated foam, plastic and residue streams | Washed and dried plastic density fractions; further sorting as required |
| Sizing basis | Appliance intake plus the resulting plastic mass balance | Plastic input kg/h, contamination and agreed output specification |
A waste refrigerator recycling line can combine pre-dismantling, refrigerant and oil recovery, controlled shredding, foam and gas treatment, metal separation and plastic washing. These modules must be specified together for the incoming appliances. The plastics washing section itself is for prepared plastic fractions and cannot accept untreated refrigerators.
Yes. Send samples of your separated plastic fraction, its polymer mix, particle size, residual metal, foam, rubber and dirt. The washing section can then be configured around the material your existing plant actually produces, with agreed feeding, controls and discharge interfaces.
Not on its own in every feed. Density separation creates fractions at selected density cut points. ABS and HIPS can overlap, and fillers or flame retardants change the behavior of individual pieces. Sample trials determine useful cut points and whether optical, electrostatic or other sorting is needed to meet a resin specification.
Washing removes surface dirt and residues, not flame retardants compounded into the polymer. Screen the incoming material, isolate unsuitable fractions and verify recovered plastics against the applicable requirements and buyer specification. A density split is not proof that a fraction is free of restricted substances.
No. This application covers selected plastic housings after appropriate dismantling. Batteries, circuit boards, displays, toner components and other non-target or hazardous parts need their own treatment routes before the plastic fraction enters crushing and washing.
Capacity and quality are defined for a specific feed and process scope. Whole-appliance intake, prepared plastic input and saleable output are different figures. Share representative material and target outlets so throughput, recovery, moisture, residual metal and polymer composition can be evaluated with an agreed sampling and acceptance method.
Tell us which appliances or plastic fractions you receive, your current preparation process and the materials you want to recover. We will assess the equipment sequence, integration scope and sample tests needed for a proposal.
