Every year about 1.25 million mattress are thrown away in Australia. That's over 15,000 tonnes of steel, almost 2,000 tonnes of polyurethane foam and significant landfill airspace.
Soft Landing is a social enterprise in New South Wales that dismantles mattresses to recover and recycle most components:
Steel Springs: Sold to scrap metal
Foam: On-sold and used for carpet underlay
Husk: Weed matting and mulch
Felt Pad: Used to make boxing bags
Timber (bases): Made into kindling, mulch and animal bedding
Fabric: Used to make boxing bags
It is a great business, and the site has some excellent video footage.
