Australia has a number of product stewardship schemes already in operation. They include: Mobile Muster, an industry-led voluntary product stewardship scheme managed by the Australian Mobile Telecommunication Association (AMTA) which addresses mobile phone waste; Cartridges for Planet Ark, which is a national product stewardship scheme for printer cartridges; the Tyre Product Stewardship Scheme which promotes environmentally sustainable collection and recycling processes to develop viable local markets for tyre-derived products; and many other schemes for plastics and containers through to batteries and oil.
