& # 39; breakthrough & # 39; Find in plastic crisis


Plastic pollution in the world's oceans can be an affordable $ 3.6 trillion, negatively affecting "almost all marine ecosystem services," including areas such as fishing, recreation and heritage.

But a breakthrough of scientists at Berkeley Lab could be the solution to the planet's eye-opening problem – recyclable plastics.

The study appeared in Nature ChemistryDetails as researchers can discover a new way to assemble the plastics and move them "into new materials of any color, shape, or shape."

"Most plastics were never made to be recycled," said Peter Peter Christensen, a postdoctoral researcher at Berkeley Lab's molecular foundry, in a statement. "But we have discovered a new way to assemble plastics that takes into consideration a molecular perspective."

Known as poly (di-ketoneamine), or PDC, the new type of plastic material could help stem the tide of plastics piling up in recycling plants, as the chains of PDC were able to be reversed by a simple acid bath, the researchers believe.

"Poly (Diketoeamine) provides a wide variety of triethones and aromatic or aliphatic amines, all of which is water only as a by-product," he says. "Recovered monomers can be re-manufactured in the same polymer formulation, without loss of performance, as well as other polymer formulations with differentiated properties.

"The ease with which poly (dimethenamine) s can be manufactured, used, recycled and re-used – without losing value – points to new directions in designing sustainable polymers with minimal environmental impact."

A by-product of kerosene, plastic is made of molecules known as polymers that are composed of carbon-containing compounds known as monuments. Once the chemicals are added to the plastic for use and consumption, the monitors bind with these chemicals and make it difficult to process in recycling plants, the researchers said.

When the plastics are chopped up in an effort to make new products, it is difficult to predict "what properties it will inherit from the original plastics," the researchers added.

Before revealing, the unpredictability of the properties made it nearly impossible to perform what was never "the grill grill of recycling", a "circular" material that can be used again and again for any number of products, including adhesives, Telephone cases, computer cables and more.

"Circular plastics and plastics upcycling are big challenges," said board helms, a staff scientist at Berkeley Lab's molecular foundry, in the statement.

"We have seen the impact of plastic waste leaking into our water ecosystems, and this trend is likely to be exacerbated by the increasing amount of plastics being manufactured and the downstream pressure being placed on our urban recycling infrastructure."

Although PDCs are only in the lab now (meaning products will not be available for some time), the researchers are excited about what they have discovered and the potential positive impact.

"With PDXs, the conventional bonds of conventional plastics have been replaced with reversible bonds that allow the plastic to be recycled more effectively," Mr. Helms added. "We were interested in the chemistry that redirects plastic life cycles from linear to circular. We see an opportunity to make a difference for where there are no recycling options."


Plastic recycling figures are trapped down, making recyclable plastics all the more important. According to the latest publicly available data, only 9.1 per cent of the plastic created in the US. There. In 2015, it was recycled, down from 9.5 per cent in 2014, according to the EPA in the US.

Last month, a particular study estimated that pollution caused by plastics in the world's oceans amounted to $ US2.5 trillion ($ 3.8 trillion) problem that every country in the world had to deal with. The review did not consider the impact of sectors of the global economy such as tourism, transport, fisheries and human health, the researchers wrote.

"An Ecosystem Impact Analysis demonstrates that it is a global proof of impact with means of high frequency on all subjects, with a means of high degree of irrevocability," the study's abstract reads, with the researchers adding that they looked at nearly 1200 data points. To come up with their conclusions.

Despite the efforts of countries around the world to reduce or end up using plastic, the amount of plastic in the world's oceans is increasing, and spread across the planet.

A separate study, published in Nature On April 16, the first study to "confirm a significant increase in open ocean plastics in recent decades," nearly 60 years ago. Research found a plastic bag that had been worn on the beach since 1965 and was possibly the first piece of plastic pollution ever found, according to the BBC.

That study is based on a 2015 investigation that estimated there were 4.8 billion and 12.7 billion pieces of plastic entering the ocean each year.
