Scientists Accidentally Create A Plastic-Eating Enzyme

The discovery may be a breakthrough in tackling the plastic pollution crisis.

 

 

By Laura Paddison

A Japanese waste dump is an unlikely location for what may be a huge breakthrough in the plastics pollution crisis.

But back in 2016, a team of Japanese scientists sifting through plastic waste found bacteria capable of breaking down and “eating” one of the world’s most popular plastics ― polyethylene terephthalate, or PET. It was hailed as a potential breakthrough at the time. But in a new twist, British and American scientists have announced that while studying this bacteria, they accidentally created a mutant enzyme that’s even more efficient at breaking down plastic bottles.

The discovery came as a team of scientists from the University of Portsmouth in the U.K. and the National Renewable Energy Laboratory in the U.S. examined an enzyme produced by the Japanese bacteria to find out more about its structure. By shining intense beams of X-rays on it, 10 billion times brighter than the sun, they were able to see individual atoms. Manipulating the structure to better understand how it worked, they accidentally engineered the mutant enzyme.

“Serendipity often plays a significant role in fundamental scientific research and our discovery here is no exception,” said John McGeehan, a biology professor at the University of Portsmouth and one of the lead scientists on the research. “This unanticipated discovery suggests that there is room to further improve these enzymes, moving us closer to a recycling solution for the ever-growing mountain of discarded plastics.”

The researchers, who published their findings in the journal Proceedings of the National Academy of Sciences on Monday, are now working to further improve the enzyme so it can be used on an industrial scale.

“The engineering process is much the same as for enzymes currently being used in bio-washing detergents and in the manufacture of biofuels ― the technology exists,” said McGeehan. It’s possible that within the next few years there could be an industrially viable process for turning PET into other substances or back into its “original building blocks” so it can be sustainably recycled, he added.

The ability to scale up the process will be crucial. Plastic pollution is fast becoming one of the biggest environmental issues of our time. The mass-produced material is ubiquitous: More than 1 million plastic bottles are bought around the world every minute. That’s more than 16,000 every second. Most of these bottles are made from PET, which can take up to 400 years to biodegrade, and many are littering the oceans. Around 8 million tons of plastics enter the oceans each year.

Bottom of Form

PET is relatively easy to recycle, but over half of global PET waste is not collected for recycling, according to research from the Ellen MacArthur Foundation, and only 7 percent of bottles are recycled into new bottles (most go into lower-value products).

Some companies that rely on PET have committed to do more. Coca-Cola, for example, which produces more than 100 billion plastic bottles a year, according to Greenpeace, has promised to increase the recycled content of its bottles 50 percent by 2020.

But progress is slow, partly because big businesses have aesthetic concerns about bottles made from 100-percent recycled plastic. The newly discovered enzyme promises to recycle plastic bottles back into new clear plastic bottles, which would require much less virgin plastic.

More than 8 million tons of plastic enters the oceans each year. By 2050 it is predicted there will be more plastic than fish in the ocean.

Some environmentalists and scientists say the breakthrough, though promising, is nowhere near enough to solve our pollution crisis.

“These enzymes are not abundantly present in nature, so you would need to produce the enzyme first, then add it to the PET plastic to degrade it,” Wim Soetaert, head of the Industrial Biotechnology Centre at the University of Ghent, pointed out. “This is likely to be a slow process. If you have gone through the trouble of collecting the PET waste, then there are clearly far better ways to recycle it or burn it for energy.” He suggested the use of commercially available biodegradable bioplastics would be a better bet.

Greenpeace’s senior oceans campaigner Louise Edge pointed to a desperate need to change recycling and consumption systems on a much wider scale.

“What we really need are system changes to reduce the volume of throwaway plastic packaging and make sure plastic drinks bottles are collected and separated effectively,” said Edge. “An enzyme alone can’t clean up the complex and widespread legacy of plastic pollution that we have already created.”

CORRECTION: A previous version of this story indicated 20,000 plastic bottles are bought worldwide every second. In fact, the number is more than 16,000.

I guarantee the result will overwhelming DISAPPROVE

..Tell you what … allow me to conduct a poll utilizing the same parameters … but utilizing my words … as Ducey’s poll and I guarantee the result will overwhelming DISAPPROVE of Ducey’s teach wage plan …. Get real any … every … the result of all polls can be manipulated to achieve whatever results one chooses…

Phoenix Business Journal: Poll: Arizona Voters Approve Of Ducey’s 20% Teacher Pay Raise

Angela Gonzales………Phoenix Business Journal……April 17, 2018

Arizona voters overwhelmingly support Gov. Doug Ducey’s plan to raise teacher pay by 20 percent — and are more likely to support legislators who support the governor’s plan, according to a new poll released by Data Orbital today.

Dubbed the 20×2020 Plan, Ducey’s plan is to raise teacher pay in Arizona by 20 percent by the start of the 2020-21 school year. It comes at a time when teachers are organizing sick-outs and potentially further walkouts or even a strike.

According to the Data Orbital poll conducted this past weekend, 75.3 percent of voters polled said they approve of Ducey’s plan to give a 20 percent pay raise to teachers. When asked if they would be likely to support a legislator who supports the governor’s proposal, 48.64 percent said yes, while 12.7 percent said they would be less likely to support a legislator who supported Ducey’s proposal.

Of those polled by Data Orbital, 39.5 percent are over the age of 65, while 20.5 percent were between the ages of 55 and 64 and 15 percent were between the ages of 45 and 54. Of those polled, 76 percent were white, while 13 percent were Hispanic, with 60 percent of the voters coming from Maricopa County.

Business leaders also support the governor’s proposal.

Gonzalo A. de la Melena Jr., president and CEO of the Arizona Hispanic Chamber of Commerce, said the growth of Arizona’s economy greatly depends on the willingness and ability of the state’s elected leaders to provide the resources needed to sustain, expand and improve the pre-kindergarten through university-level public education system.

"Our teachers deserve a significant pay raise, and the governor’s earnest proposal moves the public debate on the issue in the right direction, he said in a prepared statement.

But, he said, he wants to be assured that the funds will not be taken from other vital social safety net programs or from other areas of the public education system.

In a statement from the governor’s office, the pay raise will start with a 10 percent pay raise for teachers by the start of the 2018 school year, adding another 5 percent pay raise in 2019 and another 5 percent pay raise in 2020.

With the average teacher pay in Arizona at $48,372, the pay raise would boost to $58,130 by the beginning of the 2020 school year.

Glenn Hamer, CEO of the Arizona Chamber of Commerce and Industry, said the governor’s plan is essential to the state’s continued success story.

"Arizona’s job creators value teachers; they are integral to the success of our state,” Hamer said in a prepared statement. “Arizona’s teachers have earned a pay increase, and our growing economy makes it possible to deliver for them.

The Greater Phoenix Chamber of Commerce also supports the governor’s 20×2020 Plan.

"The Greater Phoenix Chamber will work collaboratively with the Governor and Legislature to ensure a fiscally sustainable and responsible plan is passed," according to a statement issued by the chamber.
