Discarded plastic finds use as colourful tiles

The tiles are touted to be heat resistant up to 150 degree Celsius, fire retardant, can bear load up to 35 tonnes, anti slippery, and recyclable.

Can be used in houses, roads, walkways, swimming pools, and wall cladding

Plastic is a giant problem across the world, choking the world’s oceans and clogging unscientific landfills. While some governments have tried banning certain types of plastic, there is still no wishing away all forms of it.

A Bengaluru-based initiative now has a solution that can utilise discarded plastic to make it useful. The Swachha-Bruhat Bengaluru Mahanagara Palike Dry Waste Collection Centre (DWCC), Attur has come up with ‘Re-Tile’, a pavement tile made from waste plastic that would otherwise end up in a landfill or be incinerated.

The tiles are touted to be heat resistant up to 150 degree Celsius, fire retardant, can bear load up to 35 tonnes, anti slippery, and recyclable.

Ramprasad V., one of the mentors to the project which has been brought about by Swachha Eco Solutions, a wing of the Swachcha NGO, said shampoo bottles, cleaners, disposable restaurant containers, milk covers and water bottles are among the discards that go into manufacturing the tiles. One tile can be manufactured out of around 15 disposable food containers, 150 polythene bags, around 30 shampoo bottles or 150 disposable spoons, he said.

“Testing is being done to see where it can be used and what different designs can be made. Wall cladding is also being readied. We are looking at the artistic aspect as well. Only homogeneous material has been used in these tiles, unlike in other similar tiles in which fly ash, sand, and other things are mixed. This makes it recyclable. You can bring this back to us five years later, and we make something again and give it back to you,” said Mr. Ramprasad.

“If someone brings us the plastic, we will also reduce raw material cost. Around 1 kg of plastic can yield four tiles. We will not accept banned plastic items,” he said.

The tiles can be used in houses, roads, apartment walkways and swimming pools, apart from wall cladding. “We have the capacity of using three to four tonnes of plastic to manufacture around 10,000 tiles every day,” he said.

The makers are trying to price it to compete with cement blocks, at around ₹70 to ₹90 per square feet, depending on load bearing capacity, quality, colour and design.
