Chemical Plastic

University of Chicago researchers said, they synthesized a new polymer plastic materials may enhance the performance of solar cells at low-cost.

A professional said that the key of this technology is to improve the photoelectric conversion rate. In the past, the similar materials’ photoelectric conversion rate are 5% to 6%, and while the new material photoelectric conversion rates have increased to 8%, and also expected to improve in the future.

According to introduction, this patent has been bought by a solar power company form California.

Compared to traditional silicon solar cells, the polymer plastic solar cells have a low cost, easy to manufacture, so has the prospect of a much broader market.

Recently, some well-known British designers and scientists develop environmental firendly water soluble plastic apparel. The inventors’ original intention is to make people pay more attention to the environment, at the same time make better use of clothing to protect the environment.

Last month, the United Kingdom issued the Environment Statistical data showed that the 5 years, the percentage of textile waste from 7% to 30%. The plastic clothes are the same as capsules, will be dissolved with water. Such plastics are made from biodegradable polyvinyl alcohol. Through the use of pigments with different weights, when the plastic into the water, the chemists to change their exercise, so that clothes dissolved in water.

Dayily waste may become a part of the railway in the future. This is based on a pilot from the UK NetworkRail. They use renewable plastics for new types of sleepers.

The pilot involved in about 20 tonnes of recycling waste materials into a new type of sleeper. These sleepers will replace some of the timber sleepers on the rural lines. During the trial, the NetworkRail will test whether they can stand the rigorous test of railway operations. If passed the test, it will be gradually extended to most of the railway.

The use of wasted plastic for recycled sleepers have a lot of advantages, at least can reduce the quantity of the buried garbage.

R & D and supply of sleepers from the i-plas, Inc. i-plas, Inc. is a waste plastic recycling business.

India Benares Hindu University researchers found a waste plastic bag can be used to enhance the life of the road, and has prepared to apply for a patent.

Indo-Asian News Service reported that on the 27th, because of non-biodegradable plastic bags, large-scale use of plastic bags has caused serious pollution of the environment. So, the new patent is a significance to the human.

The researchers said that after the heat treatment, the polyethylene which is a composition of plastic bags could parcel the stones used to pave the way, thereby effectively stick together with the coal tar. So the road will not crack easily after soaking.
