- Independent recyclers and scrap yards also accept specified appliances like washing machines, dryers and stoves for recycling.
- For appliances containing hazardous chemicals like refrigerants or mercury, specialized waste collectors provide appropriate disposal services.
- Charities like Goodwill sometimes arrange pickups when you donate old functioning appliances.
- Retailers selling new replacements often can take away the old appliance for recycling when delivering the new one.
Schedule Transportation
- Making transportation arrangements is an important part of responsible appliance disposal.
- You can carry smaller appliances to recycling facilities yourself. However, appliances like refrigerators require special handling.
- Hiring appliance disposal services to transport larger units ensures safety and compliance with regulations during appliance recycling.
- If undertaking disposal independently, use strapped-down trailers, trolleys and ramps to move appliances safely without risk of toppling or damage.
Step 5: Seek Proper Documentation
- At handover, recycling facilities and appliance disposal services should provide documentation detailing that transportation and recycling processes comply with EPA guidelines.
- The documentation provides assurance that hazardous materials were removed and disposed safely prior to recycling.
- Retailers also generally provide appliance disposal certificates when taking away old units.
Following these best practices conscientiously reduces environmental impact and safety risks.
What Happens During Appliance Recycling
Once appliances reach recycling facilities, they undergo separation into their constitute materials so these can be recovered and reused:
Sorting and Dismantling
Workers sort appliances by type before sending them along specialized recycling lines. Appliances then get dismantled into separate categories of materials:
- Metals – Steel, aluminum, copper
- Plastics – Widely varying polymer types
- Glass – Screens and panels
- Fluids – Coolants, lubricants, and mercury
- Insulation and wiring
- Miscellaneous – Wood, cardboard
Sorting facilities are equipped with machinery like electromagnets to efficiently extract metals. Plastics also get identified by polymer types for optimal reuse.
Metal Recovery
Metals comprise the majority of appliance mass, making their recovery critical for recycling success.
- Steel – Most widely recycled metal globally. Steel from appliances and other products gets melted down to reuse in new metal products. Recycling steel requires 75% less energy than producing raw steel.
- Aluminum – Extremely energy intensive to produce originally. Recycled aluminum thus yields 95% energy savings compared to virgin aluminum production.
- Copper – Highly valued metal reclaimed through appliance recycling. More expensive than extracting ore, so recycled copper reduces mining impacts.
Recovering metals via appliance recycling stops wasteful stripping of finite natural resources. Metals retain properties like tensile strength through repeated recycling.
Plastic Recycling
Although all appliance plastics get separated, not all types boast strong markets for reuse.
- ABS, HIPS and PP – Most common appliance plastics also widely reused in 3D printing filaments, garden furniture and automotive components.
- PVC – Toxic chlorine content means appliances replace PVC with safer polymer alternatives. Markets for recycled PVC decreasing.
- PU Foams – Refrigerator insulation gets recycled into carpet underlay.
- Epoxy Resins – Difficult to reprocess economically so get used as filler in concrete manufacturing.
Plastics that pose recycling challenges may get waste-to-energy converted or safely landfilled as a final option.
Hazardous Substances Management
Facilities have dedicated processes for capturing toxic materials:
- Ozone-depleting refrigerants get captured for reclamation and purified for reuse in cooling systems. Preventing venting is mandatory.
- Mercury gets stabilized on-site before transport to hazardous waste facilities with stringent safety standards.
- Appliance oils and lubricants also get managed as hazardous waste to avoid environmental contamination.
Proper hazardous waste disposal forms an integral focus of ethical appliance recycling facilities.
Energy Recovery
While the priority lies on material recovery through recycling, some residual waste gets channeled for energy recovery:
- Waste-to-energy incineration generates electricity through controlled combustion.
- Landfill gas capture systems process methane emissions into an energy source.
Although waste-to-energy gets criticized, technology advancements have improved its environmental performance.
Legislative Guidelines for Appliance Disposal
Various policy and legislative initiatives strive to promote responsible appliance disposal.
Federal Laws
- The Resource Conservation and Recovery Act (RCRA) enacted Federal waste management standards for environmentally sound disposal technologies.
- The Clean Air Act enforces refrigerant capture during appliance disposal to prevent ozone layer depletion through release.
