New Delhi: Doing its bit to control air pollution, Meru Cabs announced on Tuesday a new service through which passengers can share their cabs ride with others.
The customers will be provided with an option of sharing their Meru cabs ride with other co-passenger who intends to travel in the same direction.
A fixed 30 percent discount on the estimated trip fare would be applicable for the customers who chose the “ride-share” option, the taxi company said. Customers will be charged a fixed fare, which will be communicated to them before booking.
The “ride-share” services were launched keeping in view the issue of traffic congestion and escalating pollution in the national capital and its adjoining areas, said the company.
“By choosing to share your personal vehicle with others or sharing a CNG-fuelled Meru cab by Ride Share, citizens can now contribute to solving the city’s travel woes,” Meru Cabs Group CEO Siddhartha Pahwa said.
The company has also introduced ‘Meru’s ICE (In Case of Emergency) feature’, which allows passengers to share details of their location with registered emergency contacts. (IANS)
Scientists in Britain and the United States say they have engineered a plastic-eating enzyme that could help in the fight against pollution.
The enzyme is able to digest polyethylene terephthalate, or PET — a form of plastic patented in the 1940s and now used in millions of tons of plastic bottles. PET plastics can persist for hundreds of years in the environment and currently pollute large areas of land and sea worldwide.
Researchers from Britain’s University of Portsmouth and the U.S. Department of Energy’s National Renewable Energy Laboratory made the discovery while examining the structure of a natural enzyme thought to have evolved in a waste-recycling center in Japan.
Finding that this enzyme was helping a bacteria to break down, or digest, PET plastic, the researchers decided to “tweak” its structure by adding some amino acids, said John McGeehan, a professor at Portsmouth who co-led the work.
This led to a serendipitous change in the enzyme’s actions — allowing its plastic-eating abilities to work faster.
“We’ve made an improved version of the enzyme better than the natural one already,” McGeehan told Reuters in an interview.
“That’s really exciting because that means that there’s potential to optimize the enzyme even further.”
The team, whose finding was published Monday in the Proceedings of the National Academy of Sciences journal, is now working on improving the enzyme further to see if it could be capable of breaking down PET plastics on an industrial scale.
“It’s well within the possibility that in the coming years we will see an industrially viable process to turn PET, and potentially other [plastics], back into their original building blocks so that they can be sustainably recycled,” McGeehan said.
Independent scientists not directly involved with the research said it was exciting, but cautioned that the enzyme’s development as a potential solution for pollution was still at an early stage.
“Enzymes are non-toxic, biodegradable and can be produced in large amounts by microorganisms,” said Oliver Jones, a Melbourne University chemistry expert. “There is strong potential to use enzyme technology to help with society’s growing waste problem by breaking down some of the most commonly used plastics.”
Douglas Kell, a professor of bioanalytical science at Manchester University, said further rounds of work “should be expected to improve the enzyme yet further.”
