Construction Company Plansto Make Roads From Recycled Plastic 3 From 4

The use of plastic makes a series of new innovations: including power generation, ultra quiet roads, heated roads, modular building.

Asphalt mix made with recycled printer toner paves way for eco-friendly roads A new, more environmentally friendly asphalt mix containing recycled printer toner is being used on Sydney’s roads.

The technology is the world’s first commercial use for toner waste, and was first used in Melbourne in 2013. Called Toner Pave, it was developed by the city’s road contractor Downer, in partnership with a cartridge recycling company, Close the Loop.

The toner is blended with recycled oil and is 40% more energy efficient than the manufacture of standard bitumen, with a relative saving of 270kg of CO2 emissions per tonne.

Every tonne of the toner-based product used in the asphalt mix replaces 600kg of bitumen and 400kg of fine aggregates, such as sand and soil.

Peter Tamblyn, marketing manager at Close the Loop, said that “the rest of the world is looking at this”.

All of Australia’s waste toner powder could the oretically one day be used in asphalt mix, Tamblyn said, but many people throw their toner out rather than recycle it.

“If we could get our hands on all of

Australia’s waste toner we would happily use it,” he said. On average, I3 % of toner in every cartridge is wasted, with 100 toner cartridges needed for every tonne of asphalt.

At the current rate of printer cartridge collections via Plant Ark within the boundary of the City of Sydney, 14,500 tonnes of Toner Pave can be produced each year – enough to repave 120,000 square metres of road, double the needs of the council area.
