Bacteria found in one of the compartments of a cow’s stomach can break down plastic, research suggests.
Since the 1950s, more than 8bn tonnes of plastic have been produced – equivalent in weight to 1 billion elephants – driven predominantly by packaging, single-use containers, wrapping and bottles. As a result, plastic pollution is all-pervasive, in the water and in the air, with people unwittingly consuming and breathing microplastic particles. In recent years, researchers have been working on harnessing the ability of tiny microscopic bugs to break down the stubborn material.
There are existing microbes that are able to degrade natural polyester, found for example in the peels of tomatoes or apples. Given that cow diets contain these natural polyesters, scientists suspected the bovine stomach would contain a cornucopia of microbes to degrade all the plant material.
