plastic, for the human production and life bring great convenience. Since the 1950 s, the global plastic average annual growth rate at 8. 5%. By 2016, the global plastic production up to 3. 3. 5 billion tons. China is the world's superpower plastic production and use, and further growth potential is very huge. Part plastic after use, however, due to the slow collection processing into the sea, causing severe ecological pollution. The United Nations estimates that each year more than 8 million tons of plastic flow into the ocean. Therefore, urgently need plastic pollution and Marine conservation measures.

recently, purdue university Davidson college of chemical engineering research team developed a new type of chemical conversion process to polyolefin waste ( A kind of plastic) Into useful products, such as clean energy and other products. Study leader LindaWang said: 'our strategy is to through all sorts of polyolefin waste into valuable products, including polymers, naphtha ( A mixture of hydrocarbons) , or clean energy, to create a recycling drive. Our conversion technologies have the potential to improve the recycling industry profits, and reduce the plastic waste. '

the technology more than 90% of the polyolefin can be transformed to a variety of products including pure polymer, naphtha, fuel or monomer. The team's partners include GozdemKilaz, assistant professor of engineering institute of technology, as well as GozdemKilaz doctoral research assistant Petr Vozka ( Renewable energy fuel laboratory of the college of engineering) , their common on this transformation process is optimized, resulting in a higher quality of gasoline or diesel.

conversion process includes the selective extraction and hydrothermal liquefaction. Once the plastic has been converted into naphtha, it can be used as the material of other chemicals or further separated into special solvents or other products. Every year from polyolefin waste clean fuel can meet the demand of 4% of gasoline or diesel fuel. The results of this research has been published recently in the ACS Sustainable Chemistryand Engineering.

Wang learned in plastic waste pollution of the Marine, groundwater and the environment decided to develop the technology. In the past 65 years of plastic ( 8. 3 billion tons) , about 12% by incineration, only 9% are recycled, while the other 79% into the landfill or ocean. The world economy BBS predicts that by 2050, if people continue to cast plastic waste into water bodies, plastic garbage in the ocean would more than fish.

the technology to convert more than 90% of the polyolefin plastic recycling.

Wang said: 'the processing of plastic waste, recycling and throw away, doesn't mean that things will be over. Plastic degradation slowly, releasing toxic particles in soil and water and chemicals. This is a disaster, because once the pollutants into the sea, we can't completely to recycle them. '

at purdue university to celebrate the 150th anniversary of the university's Giant Leaps celebration, announced that the progress of global sustainable development is the theme of the celebration, one of the study that coincide with the theme. The last one year celebration of the concept of 'day' a total of four theme, that is the purpose of these themes at purdue university as a centre of knowledge to solve the problem of the world.

Wang said she hopes the technology can promote the development of recycling industries, and quickly reduce the number of plastic rubbish. She and her team are looking for investors or partners, and to help them to show the technology on the commercial scale. Wang technology has been through purdue university research foundation technology commercialization office to apply for a patent. Conversion table packaging printing knowledge
