For almost two weeks, I have been consciously reducing my plastic use and advocating a plastic-free life. I stopped buying plastic bottles or plastic bags and every time I go to grocery shopping I carry my own reusable bag or containers. By doing so, I have been quite successful to reduce my plastic consumption compared to last month. In fact, it started becoming an addiction to re-use everything that I have, including the plastic zipper bags and containers. As a good alternative to conventional plastics, I started believing in compostable plastics that would replace most areas in our daily life.
Scientists at Imperial College London report that they have invented a polymer, made from non-food sources, that could be used in packaging and then tossed into compost piles or landfills, where it degrades upon contact with water.
The scientists said they worked three and a half years on a biodegradable polymer that is made from sugars known as lignocellulosic biomass, derived from fast-growing trees, grasses, and agricultural and food wastes.
Lead researcher Charlotte Williams said the team accomplished its goal of producing the polymer from non-food sources and using small amounts of water in the process — an advantage over another biorenewable plastic, polylactide, whose manufacture requires large amounts of water and energy.
