In the production of biogas compostable plastic for breakthroughs in the production of biogas compostable plastic for breakthrough
in the face of increasingly severe global plastic pollution, many scientists are doing effort, research and development of different kinds of biodegradable plastics, also put forward a lot of interesting and valuable ideas and vision, which employ home compost bin, will drop plastic bottles into one and can produce methane decomposition scheme for family's electricity is one of the idea.
now, the researchers show biological plastic and some mixtures can be resolved under different conditions, adumbrative we took an important step towards the future plan. And they in ACS journal Environmental Science& Technology, 'reported their results.
white pollution is a global environmental problems, especially in the sea - — Pieces of plastic or plastic article can damage or winding in the sea animals and birds, that these animals die. Although plastic recycling level has increased in many countries, but most of the plastic waste in landfills or still exist in our living environment.
scientists have developed a biodegradable plastic, but they often lack the flexibility, strength and toughness of traditional plastic. A mixture of different biological plastic can improve of these features, but they are in harmony with the environment is uncertain. Tanja Narancic, Kevin O 'Connor, Ramesh Babu Padamati and his colleagues wanted to study a variety of biological degradation situation of plastics and its mixture under various conditions.
15 different researchers studied the degradation of plastic and its mixture under the condition of artificial management, namely in such as compost and anaerobic bacteria. And in the management environment, namely the degradation in soil and water or seawater. Polylactic acid ( PLA) Is one of the most popular biodegradable plastics on the market, but it requires under the condition of high temperature to decompose, and cannot be compost at home.
what's surprising is that in a typical family composting conditions, the PLA and poly (caprolactone ( PCL) Can be decomposed to the mixture of carbon dioxide, biomass and water. Many separate plastic mixture and tested under the condition of anaerobic digestion can be broken down, the process can produce methane gas, and all plastic degradation by industrial composting.
the researchers say, biodegradable plastic mixtures can create new possibilities for plastic waste management. However, in all the soil and water conditions, only two kinds of plastic, poly hydroxybutyric acid ester ( PHB) And thermoplastic starch ( TPS) Able to complete decomposition.
so, biodegradable plastic is not the best way to solve the plastic pollution, the researchers point out that biodegradable plastic should be carried out after the consumer use of effective management. Conversion table packaging printing knowledge
