The vast majority of plastic can't be or won't be recycled. Editor's note: NPR will be publishing stories from this investigative series in the weeks ahead, even as we focus our current coverage on the coronavirus pandemic.
But here's a look at some of our key findings. You can watch the full documentary film from this investigation on the PBS series Frontline. For decades, Americans have been sorting their trash believing that most plastic could be recycled. But the truth is, the vast majority of all plastic produced can't be or won't be recycled. In a joint investigation, NPR and the PBS series Frontline found that oil and gas companies — the makers of plastic — have known that all along, even as they spent millions of dollars telling the American public the opposite.
Starting in the late s, the plastics industry spent tens of millions of dollars promoting recycling through ads, recycling projects and public relations, telling people plastic could be and should be recycled.
But their own internal records dating back to the s show that industry officials long knew that recycling plastic on a large scale was unlikely to ever be economically viable. A report sent to top industry executives in April called recycling plastic "costly" and "difficult. Despite this, three former top officials, who have never spoken publicly before, said the industry promoted recycling as a way to beat back a growing tide of antipathy toward plastic in the s and '90s.
The industry was facing initiatives to ban or curb the use of plastic. Recycling, the former officials told NPR and Frontlinebecame a way to preempt the bans and sell more plastic. Another top official, Larry Thomas, who led SPI for more than a decade untilsays the strategy to push recycling was simple:. It was the late s, and the plastics industry was under fire as concern mounted about ever-increasing amounts of garbage. But the industry had a plan — a way to fend off plastic bans and keep its sales growing.
In interviews, current plastics industry officials acknowledged that recycling the vast majority of plastic hasn't worked in the past. But they said the industry is funding new technology that they believe will get recycling plastic up to scale. Today, it truly is not just PR. We don't like to see [waste in the environment] either.
We really don't. We want to solve this.PBS have excellent mechanical performance, almost same as PP and ABS, good heat resistance and outstanding process ability allows it to be variously processed on conventional blown film plants, it is the best biodegradable plastic in terms of process ability in current market and can be blended with a great quantity of calcium carbonate and starch etc.
Our PBS is completely degradable according to various international standards and regulations like European standard EN and American Standard ASTMwhich will be eventually biodegraded to carbon dioxide, water and biomass when metabolized in the soil or degradable under standard conditions.

Early forms of plastic have existed since the mids. But when WWII came along, scientists diverted all their plastic technology to help with the war effort.
So after the war, all this plastic needed to go somewhere, so why not the American consumer? These tiny bits of plastic make their way into oceans, creating a plastic soup of pollution that can get into the bellies of all kinds of marine animals like fish, pelicans, and turtles. Some research studies predict that bypound for pound, plastics in the oceans will outweigh all the fish. On top of that, plastic bottles are made from fossil fuels.
In fact, the Pacific Institute found that it took about 17 million barrels of oil to produce enough plastic for the bottles of water consumed by Americans in But banning plastic bottles altogether can have unintended consequences.
And switching to alternatives like glass or metal containers can require more energy to transport because they weigh more. That means burning more fossil fuels and creating more pollution.

Thanks for signing up for our newsletter.Polybutylene succinate PBS sometimes written polytetramethylene succinate is a thermoplastic polymer resin of the polyester family.
PBS is a biodegradable aliphatic polyester with properties that are comparable to polypropylene. The synthesis of succinic acid based polyesters was first performed in This early work was pursued in the s by Wallace Hume Carothers E. In that time the purpose of such study was to find a synthetic alternative to natural silk fiber. Carothers, by eliminating water on a continuous distillation process, obtained polymers with molar masses significantly higher than what was previously synthesized.
Thus Carothers put more attention on polyamides and invented with his colleague Julian Hill Nylon 6,6. Later Flory proposed an improved synthesis of aliphatic polyesters with diacid chloride.
In the beginning of the s, after being forgotten for more than 40 years, these polymers received a renewed interest due to the increasing demand on biodegradable and bio-based polymers. Like other polyesters such as PETtwo main routes exist for the synthesis of PBS: the trans-esterification process from succinate diesters and the direct esterification process starting from the diacid.
The direct esterification of succinic acid with 1,4- butanediol is the most common way to produce PBS. Its consists in a two steps process. First, an excess of the diol is esterified with the diacid to form PBS oligomers with elimination of water.
Then, these oligomers are trans-esterified under vacuum to form a high molar mass polymer. This step require an appropriate catalyst such as titaniumzirconiumtin or germanium derivatives. Amycolatopsis sp. HT-6 and Penicillium sp. Microbispora roseaExcellospora japonica and E. As PBS decomposes naturally into water and CO 2 it may be a biodegradable alternative to some common plastics. The scope of PBS application fields is still growing and several areas can be identified but it remains difficult to know precisely in which specific object PBS is actually used.
First in the packaging field, PBS could be processed into filmsbags, or boxes, for both food and cosmetic packagings. Other applications of PBS could be found as disposable products such as tableware or medical articles. In agriculture, PBS finds interest in the fabrication of mulching films or delayed release materials for pesticide and fertilizer.
PBS is also promise to find market shares in fishery for fishing netsforesterycivil engineering or other fields in which recovery and recycling of materials after use is problematic. In industry, the improvement of the PBS synthesis allowed the large scale production of this polymer.
The Japanese company Showa High Polymer, built in a semi-commercial plant able to produce 3, tons of polymer per year. This polymer has high molar masses without the use of a chain extender. The same year Xinfu Pharmaceutical announced the building up of the world's largest continuous PBS production line with an annual capacity of 20, tons. At the moment most of these poly alkylene succinate s are synthesized from petrochemical precursors.
Nevertheless most of the producers are evaluating or developing bio-based succinic acid for the synthesis of these polyesters. InShowa Denko announced termination of the production and sale of Bionolle, citing delay in permeation of environmental regulations on plastic shopping bags and a fall in market prices of biodegradable plastics.
