Trinidad and Tobago faces the annual challenge of discarding over a million used tyres, which often clog up rivers and create an environmental hazard.
But Planning Minister Pennelope Beckles says research being done by the Caribbean Industrial Research Institute (CARIRI) and the University of T&T (UTT), shows that old tyres can be repurposed for road paving and the creation of new rubber products.
Speaking to reporters during a tour of a $1 million Rubber Crumb Production Facility in Tarouba, San Fernando yesterday, Beckles said CARIRI is currently experimenting to assess the durability of the rubber mixture for road paving.
She said rubber crumbs can also be used for manufacturing rubber mats, linings and other products for use in sporting and recreational facilities.
Asked whether rubber crumbs in asphalt paving could be helpful to reduce T&T’s bitumen shortages, Beckles said this was not her area of technical expertise. However, she said the test results of the rubber crumb pilot project will be shared with the Works and Transport Ministry for further assessment and analysis.
“Every person here today understands the significance of a project of this nature. It has taken a while in coming and I am pleased that CARIRI and UTT have seen to the use of tyres for projects like these,” Beckles said.
She noted that the project has generated interest from the Solid Waste Management Company Ltd (SWMCOL) as it can help reduce the burden on the nation’s landfills. She also said the project will allow people to earn revenue from old tyres.
Saying it was part of the government’s economic diversification strategies, Beckles said rubber crumbs have been used successfully in other countries for paving works in sporting facilities and manufacture of products.
Meanwhile, chief executive officer of CARIRI Hans-Erich Schulz said T&T generates 1.5 million used tyres annually.
Many of these tyres end up in landfills and are breeding grounds for mosquitoes, Schulz lamented.
“We are testing the technical feasibility for utilisation of these tyres for road paving. Later today we will be paving a strip of roadway in Tunupuna. Another test strip will be paved using a standard asphalt mix design,” he revealed.
He added: “Over the next year we will be testing and monitoring it to see how well it holds up to weather and traffic. The idea is to use hard data.”
Schulz also agreed that the rubber crumb facility offers a way to safely dispose of old tyres and recycle them for uses which are both environmentally friendly and economically beneficial.
Meanwhile, UTT president Professor Prakash Persad said the project was part of the university’s mandate to promote research and development. He said aside from the rubber crumbs facility, UTT students have developed innovative products, including a special brew made with chatagne seeds, providing a coffee-like taste.
