Results Recycling as a waste management strategy provides opportunities to reduce the use of petrochemical resources and improving environmental conditions. Reuse of bulky plastic wastes in concrete and Wood Plastic Composites WPC seems a smart approach for
Current practices in the generation and disposal of synthetic polymers are largely unsustainable, causing severe worldwide polymer pollution and enormous materials value loss. To address these dire environmental and economic issues, several research fronts aim to develop sustainable polymers with closed-loop life cycles.
2017-6-7Chemical recycling, which can take many forms from high-temperature pyrolysis to mild, solution-based catalytic depolymerization, can afford enormous economic and environmental benefits.
Several concurrent developments are shaping the future of plastics. A transition to a sustainable plastics system requires not only a shift to fossil-free feedstock and energy to produce the carbon-neutral building blocks for polymers used in plastics, but also a rational design of the polymers with both desired material properties for functionality and features facilitating their recyclability.

1992-1-1The construction industry is one of the major consumers of polymers and a significant potential customer for recycled plastics products. The growing problems with municipal solid waste MSW disposal space, the proliferation of polymer products, and public awareness of environmental issues makes it necessary for the construction industry to become actively involved in post-consumer
2020-6-23Gold recovery from electronic waste could prevent excessive mining with toxic extractants and provide a sustainable path for recycling precious metals. Unfortunately, no viable recycling is practiced, except burning electronic circuit boards in underdeveloped countries, mainly because of the lack of chemical scavengers as adsorbents. Here, we report the synthesis of a family of porphyrin ...

2020-2-8Recycling also uses less energy and and great way of controlling air, water and land pollution. Effective recycling starts with household or the place where the waste was created. In many serious countries, the authorities help households with bin bags with labels on them. Households then sort out the waste themselves and place them in the ...

Polymers made of even slightly different repeat units are usually immiscible and form materials with two separate phases, like oil and water. Not only do different polymers not mix, but the interfaces between them are very sharp and mechanically weak. This lack of interfacial strength poses a very serious challenge to the recycling of blends of different polymers and, notably, polyethylene PE ...
Recycling of plastic is an established technology contributing to a circular economy. A sustainable society requires recycling to produce high quality feedstocks from all types of reusable waste. New recycling technologies will help to improve waste management practices, for instance dissolving plastic waste in a solvent to purify and maintain ...

The polymers which are degraded and decayed by microorganisms like bacteria are known as biodegradable polymers. These types of polymers are used in surgical bandages, capsule coatings and in surgery. For example, Poly hydroxybutyrate co vel PHBV High-Temperature Polymers. These polymers are stable at high temperatures.
Polymers, commonly called plastics, have become so widely used that global production is expected to exceed 500 million metric tons by 2050. This rising production, combined with rapid disposal and poor mechanisms for recycling, has led to the prediction that, by 2050, there will be

2020-2-13Recycling Activity Sheets It is important that we put the right things in the recycling bin. Recycling helps us save energy, water, sand and trees. We should only put plastic bottles, plastic containers, cans, steel tins, glass bottles, paper and cardboard in the recycling bin. We cant recycle drinking glasses, broken plates, cups and foil.
How can a scientist or engineer synthesize and utilize polymers to solve our daily problems This introductory text, aimed at the advanced undergraduate or graduate student, provides future scientists and engineers with the fundamental knowledge of polymer design and synthesis to achieve specific properties required in everyday applications.
Nearly all types of plastics can be recycled, however the extent to which they are recycled depends upon technical, economic and logistic factors. As a valuable and finite resource, the optimum recovery route for most plastic items at the end-of-life is to be recycled, preferably back into a product that can then be recycled again and again and so on.

2015-6-3Technical polymers could be identified by means of their remarkably strong auto fluorescence. The time constants of this fluorescence proved to be characteristic for the individual polymers and can be economically determined by integrating procedures. The thus obtained unequivocal identification is presented for their sorting for recycling.
