Silicon Nitride Ceramic:

"The rapid biodegradation of plastics in the intestine of yellow mealworm reveals the new fate of discarding plastic waste in the environment." said Professor Yang Jun from Beijing University of Aeronautics and Astronautics. Plastics are difficult to degrade naturally in the environment, and polystyrene is the most. Due to its high molecular weight and high stability, it is generally believed that microorganisms cannot degrade polystyrene plastics. In 2015, Professor Yang Jun's research group of Beijing University of Aeronautics and Astronautics, Dr. Zhao Jiao of Shenzhen Huada Gene Company, etc. co-published two sister research papers in the authoritative journal "Environmental Science&Technology" in the field of environmental sciences, which proved the yellow mealworm (breadworm) The larvae can degrade polystyrene, the hardest plastic. The study showed that with polystyrene foam as the only food source, the larvae of Tenebrio molitor can survive for more than one month and finally develop into adults. The polystyrene they eat is completely degraded and mineralized into CO2 or assimilated into insect bodies. fat. This discovery provides ideas for solving the global plastic pollution problem. The pollution of plastic waste produced by petrochemical industry is a world environmental problem. Most plastics are discarded after one-time consumption. So far, academic circles believe that plastic products may not be decomposed in the natural environment for tens to hundreds of years due to their stable physical and chemical structure. Professor Yang Jun introduced that in 2013, the global consumption of 299 million tons of plastics, of which polystyrene plastics accounted for 7%, consumes about 21 million tons per year. Common plastic lunch boxes, coffee cups and other materials that can withstand boiling water temperature are polystyrene . Authoritative investigations have shown that in the microbial community of soil, sludge, decaying garbage, or manure, polystyrene, such as plastic, only degrades in the range of 0.01%-3% in 4 months.
