Recently, Chinese scientists made a major breakthrough in the field of Biodegradable Plastics: researchers first discovered new species can efficiently degrade polyurethane plastics -- the fungus Aspergillus tubingensis, is expected to become a tool for future control of white pollution "". The results have been published in the International Journal of environmental pollution.
Polyurethane is one of the fastest growing varieties in modern plastic industry. It is widely used in the fields of industry, medicine, construction and automobile. At present, most of the waste plastics are mainly treated by landfill and incineration, but the former occupies the land resources and is easy to pollute groundwater. This kind of degradation cost is high and easy to produce two pollution, and more environmentally friendly biodegradation has been the difficulty of global plastic pollution research.
The study pointed out that in the "Tabin Aspergillus" function, originally in the natural environment difficult degradable plastic, two weeks can clearly see the biodegradation process, two months after the training of plastic polymer based basically disappeared.
In the future, researchers will gradually determine the ideal conditions for large-scale rapid propagation of fungi and plastic biodegradation, for the use of industrial fungi to degrade plastic waste, plastic waste disposal to lay the foundation.
