Although they're not recycling "wild" ocean plastics, the process and the products offer tantalizing prospects for entrepeneurial companies looking to create composite building products.

As reported by Laurissa Smith,ABC Rural
A Tasmanian company recycling the state's farming and fishing industry's plastic waste is looking to expand its operations interstate.

Envorinex at George Town in the north-east, turns thousands of tonnes of plastic from salmon pens, silage wrap and irrigation piping from the mining sector into a range of building products.The company's managing director Jenny Brown said they were spending millions of dollars upgrading their own plant, but there was demand elsewhere to establish more sites.

"We have been approached by New Zealand, but that's a very small industry," Ms Brown said. "We've also been approached by Port Lincoln as well, for their tuna industry.

"Very similar to our salmon industry, they have the same sort of pens, they have the nets, so the same sort of waste issues, but they also have their oyster industry. "So all of their oyster baskets, floats ... We're currently doing a feasibility study on that."

Plastic turned into variety of items

Envorinex recently signed a contract with Tasmanian salmon producer Tassal to recycle its fish pens.

The business has also developed matting shipped to Scotland for oil rigs there, and used locally on fishing boats and inside dairies.

Other waste is moulded into septic systems exported to Papua New Guinea and Fiji as well as for use as webbing material for luggage lining in Vietnam.

Excess recycled material is sold interstate for high density polyethylene.
