Envision mature age employment co-ordinator Martin Collins said the City of Launceston provided bins in the Town Hall and the Waste Management Centre at Mowbray for people to dispose of their milk lids in.

"We do ask people to wash their lids before they donate them - one dirty lid can contaminate the batch and it really increases our workload," Mr Collins said.

"The main purpose of the exercise is to divert bottle lids from landfill because they are traditionally not recycled because of the work that's involved in separating and processing them."

The lids are then sorted into various types of plastics and some of the lids are processed and extruded into 3D printing filament.

This filament is then used to print mobility aid prostheses for children in developing countries.

"We are fortunate in Australia in that children who require a prosthetic device have access to very high levels of technology in terms of the devices available to them - that's not the case in developing countries," Mr Collins said.

The remaining lids are processed and made into bricks and pavers that will be donated to local schools and aged care facilities.

"We're going to be donating the bricks to primary schools and aged care facilities to make things like raised garden beds," Mr Collins said.

"In primary schools, for example, this will not only teach the socially responsible aspect of recycling a waste product into a useful item but also how to grow their own food."

Mr Collins said while various milk lids, in particular, can be used to make ability aids, any bottle lid can be donated and used to manufacture bricks and pavers.

Mr Collins said the Launceston Envision facility will soon have extruder and injection moulder mechanisms that will help speed up the process of manufacturing items.

"We'll not only be able to produce our own hands in Launceston, we'll be producing the raw materials from the donated lids from the community," he said.

The Launceston facility also installed two 3D printers, with more on the way.
