The elastomeric materials manufactured by the technology can be used in various applications, including in footwear, auto parts, toys, sports gear, and household products.
The technology, the joint statement added, also provides solutions for carbon neutrality and circular economy.
According to King Steel’s website, the technology melts polymers into a liquid state and evenly mixes it with nitrogen or carbon dioxide without producing any chemical reaction.
“The finished product maintains its original macromolecule state,” which according to King Steel makes the product fully recyclable.
Furthermore, the process replaces “toxic chemical foaming agents” with carbon dioxide or nitrogen “to create a foaming agent from ordinary air”.
The technology creates a “supercritical fluid” through a specific temperature and pressure.
Then, the fluid homogeneous phase compresses the fluid polymer and adjusts gas in the molten material to produce even mixing.
When the mixed material is injected into the forming mould, air pockets are created due to temperature and pressure changes, achieving the foaming of the elastomeric materials.
“With the support of King Steel’s NexCell technology, we are confident in the market development of sustainable material solutions using physical foaming processes to replace traditional non-recyclable materials,” said Kin Wah Chay, managing director of BASF Taiwan.
According to Chay, the partners are jointly exploring business opportunities in footwear, sports and leisure industries.
Ascon Resource Management Holding and RIO Oceans Integrity have signed a recycling contract for ocean plastic.
The Indonesian organization RIO Oceans Integrity and the German company ASCON Resource Management Holding GmbH have signed a long-term recycling contract on October 1, 2022. The cooperation includes the recycling of plastics collected worldwide from rivers, beaches and oceans in a circular economy based on a socially responsible and efficient operational model.
The aim is to establish recycling operations that are as regional as possible in order to keep the added value in the respective countries. This is the basis for using recycling to reduce poverty in many countries by establishing local, economically successful recycling companies. It is precisely the integration into a global secondary raw materials market that underscores the importance of community recycling activities.
“The German and European discussions about the recyclability of packaging to the respective legal quota fulfillment to chemical recycling does not get a plastic bottle out of the ocean”, Sascha Schuh, CEO of ASCON Resource Management Holding, who outlined his company’s motives for the cooperation. “We want and have to face the global challenge to prevent the fact that still more and more plastic waste is carried via rivers into the oceans. Achieving this by recycling in the respective countries is our joint mission with RIO,” Schuh explained as the basis for the cooperation.
Kieran Kelly, Chairman of RIO Oceans Integrity, emphasized that recycling in particular has a supporting role to play. “Our goal is to make rivers cleaner, alleviate poverty in the world’s poorest areas through our projects, and strengthen plastic recycling as a response to greenwashing,” Kelly said, describing his organization’s reasons for this collaboration. “Working together on projects in Africa with ASCON, we could see our common path and mutual professionalism. Therefore, signing a long-term recycling contract was a logical step for us,” Kelly concluded.
With the current surge of interest in renewably sourced materials, the timing could almost not be better to bring a new PHA production facility on stream. In May of this year, CJ Bio, a division of South Korea- based CJ CheilJedang, did just that. Sustainable Plastics talked with Max Senechal CCO, CJ Bio about PHA, the new plant and CJ Bio’s very considerable ambitions for the future.
CJ Bio’s first PHA plant, located in Pasuruan, Indonesia, has a rated capacity of 5,000 tonnes and is the sole producer in the world of amorphous PHA, a softer, more rubbery version of the PHAs that are currently being produced elsewhere. The product is essentially an evolution from the amorphous material developed by Metabolix back in the 2014, 2015 time frame, according to Max Senechal, who was at that time working at Metabolix. The Korean biotech company acquired the PHA technology from Metabolix in 2016 and has directed considerable resources over the past four to five years at improving and scaling up the technology.
“As one of the biggest biotech companies in the world, CJ is mostly known for its amino acid business, animal feed business lysine methionine and so forth, “ he said. “The technology that’s employed to ferment amino acids is actually very similar to the technology used to make PHAs. In other words, from a technology point of view, there are a lot of synergies and similarities.”
At the time CJ was also exploring activities beyond just amino acids, including setting up several internal programmes that involved using biotechnology to produce chemicals. “Moving into PHAs made a lot of sense,” said Senechal. “Significant improvements were made to the microbiology – to the strain engineering as well as to the process to produce at large scale,” he added.
The company’s first product out of the gate is amorphous PHA, the reason being, said Senechal, is because it’s a highly differentiated PHA.
“Also, the material is an excellent modifier for other biopolymers and therefore allows us the ability to leverage the positioning of some current bio polymers in the market and get to market quicker that way. But I also want to make it very clear that we have a much broader portfolio of technology then just the amorphous PHA. CJ certainly has the intention to launch other grades of PHAs that will broaden the market exposure in the very near future.”
Bioengineering, a core expertise
PHA is not just one material, but a family of perhaps several hundred different types. As a company seeking to gain a commercial foothold in the PHA space, differentiation is important, said Senechal. He emphasized that, while all PHAs are produced in more or less the same way – “It’s all fermentation, it’s all intracellular accumulation of the polymer” – the actual differentiation occurs with the ability to engineer microbial strains in order to design PHAs with specific characteristics.
Indorama Ventures Public Company Limited (IVL) has announced the official opening of its PETValue bottle-to-bottle recycling plant in the Philippines, in partnership with Coca-Cola Beverages Philippines – the bottling arm of Coca-Cola in the country.
The plant is IVL’s, a global sustainable chemical company, latest recycled PET facility as the global integrated petrochemicals company says it is building on its position as the world’s “largest producer” of recycled resin used in plastic beverage bottles.
PETValue Philippines, located in General Trias in Cavite Province south of Manila, is the country’s first food-grade, bottle-to-bottle recycling facility, and the largest in the Philippines, IVL says.
The facility was built by IVL in partnership with Coca-Cola Beverages Philippines, Inc. in accord with The Coca-Cola Company’s “World Without Waste” program to collect and recycle the equivalent of every bottle it sells by 2030.
In 2020, we signed a joint venture agreement with Coca-Cola to build a state-of-the-art recycling plant in the Philippines.
As a result of the joint venture with Coca-Cola, IVL says it will recycle about 2 billion additional used PET (polyethene terephthalate) plastic bottles in the Philippines every year and create about 200 new local jobs. The plant will wash and shred post-consumer bottles into flakes to produce recycled PET resin that is suitable for use in food-contact applications.
IVL says it has already surpassed the halfway milestone towards meeting its 2025 target of increasing its recycling capacity to 750,000 tons per year. The company continues that it is investing US$1.5 billion globally to expand recycling facilities and sustainable production, including a new ambition to reach post-consumer PET bale input of 1,500,000 tons per year by 2030.
PETValue will introduce the most advanced technology and infrastructure in the Philippines, helping to improve collection and recycling rates and prevent leakage into waterways, IVL says. The company continues that the new plant will encourage a more robust waste value chain to help address the growing post-consumer waste management problem in the Philippines.
The “unique” PET plastic used in soft drinks and water bottles is 100% recyclable and the most collected plastic packaging in the world, IVL says, global brands including Coca-Cola is using more recycled plastic in their bottles to close the loop and “deliver a circular economy”.

Chemical recycling technologies can have significant climate benefits compared to virgin resin production, landfilling and waste-to-energy incineration, according to a new study.
The Oct. 12 study from the City College of New York, which was commissioned by the American Chemistry Council, said the technologies can process hard-to-recycle plastics into new products in a more climate friendly way than using virgin resources.
“As advanced recycling becomes increasingly efficient, it is poised to play a major role in achieving global sustainability goals,” said Marco Castaldi, an author of the study, professor of chemical engineering and director of CCNY’s Earth Engineering Center.
“It can transform hard-to-recycle plastics into a multitude of high-value feedstocks, reducing the need for fossil resources and limiting the environmental impact of waste management,” he said. “Equally important, the data suggest that our transition to a more circular economy will dramatically improve climate outcomes.”
The report looked at 13 life cycle assessments for the technologies, which it refers to as advanced recycling.
It said that while results vary based on processes and materials, it said advanced recycling can reduce the need for fossil energy resources by up to 97 percent compared with landfilling.
As well, it said the technologies can reduce carbon dioxide emissions by more than 100 percent in some cases, “when accounting for displaced demand for chemical products and energy.
The CCNY study, however, did not seem to directly compare chemical recycling processes to traditional mechanical recycling technologies.
Other studies have found a lower carbon footprint for mechanical recycling for plastics, vs. chemical recycling.
A late September study from Zero Waste Europe, for example, found that pyrolysis, one of the more common chemical recycling technologies, can have greenhouse gas emissions that are nine times higher than mechanical recycling.
The costs to society from plastic pollution — including environmental clean-up, ecosystem degradation, shorter life expectancy and medical treatment — exceed US$100bn per year, according to new research which sheds light on the growing global plastics crisis.
A detailed study by Minderoo Foundation and undertaken with legal firm Clyde & Co and Praedicat, a liability risk consultancy, shows that plastic’s range of harmful impacts could trigger potentially colossal liability claims against the petrochemical industry, which manufactures the polymers and chemical additives used in plastic.
Just as oil and gas companies are now starting to be held legally and financially accountable for the climate change impact of their products and chemical companies for damaging the environment and human health (e.g. PFAS, glyphosate), a new wave of litigation is expected to emerge around plastics.
The report finds that just like fossil fuel companies and the climate impact of their products, plastic producers and distributers create the most extreme negative nature and human harming externalities ever witnessed in the history of mankind—a price borne by every child, woman, and man on this planet.
Legal action is expected to centre on the US, where the study forecasts corporate liabilities from plastics litigation triggered in 2022-30 could exceed $20 billion. Future claims, beyond 2030, could be an order of magnitude larger.
The research is supported by the United Nations Environment Programme’s Finance Initiative.
The study finds that manufacturers of chemical additives used in plastics, many of which have well-established, harmful links to human health, are the most exposed to litigation risk.
Also exposed are manufacturers of plastic polymers, whose products ultimately degrade into micro- and nanoplastic particles, which persist in the environment for decades, entering the human food chain. They are rapidly emerging as major public health and environmental threats.
These companies have been protected against financial consequences by the complexity of attributing pollution back to its source, but scientific methods and legal doctrines are evolving; plastic pollution liabilities are expected to follow.
The plastics industry, shareholders, insurers, and regulators need to work urgently together to disclose the scale of exposures and liabilities to date, to prevent further damage and set aside the resources necessary to deal with the consequences.
With complete systems for plastics recycling from a single source, Coperion intends to set new standards for the industry. At K 2022, the company presents complete plastics recycling solutions.
Complete systems for industrial-scale plastics recycling from a single source – the recently completed merger between Coperion and machine manufacturer Herbold Meckesheim makes it possible. Coperion, technology leader in extrusion and compounding, bulk material handling and feeding systems, brings its own expertise in the field of recycling together with that of Herbold Meckesheim, specialist in the mechanical recycling of plastic and plastic waste, forming a new Recycling Business Unit. This new Business Unit makes innovative process solutions possible, supporting the efforts towards a circular economy in the plastics industry. Coperion is providing a first look at its integrated recycling solutions at K 2022 (19-26 October 2022, Dusseldorf) at its booth 14/B19, at its Recycling Pavilion in the open-air fairgrounds (CE09), and at Herbold Meckesheim’s booth 9/B34.
The newly created Recycling Business Unit is able to offer modular system and plant solutions that combine the complementary technologies of Coperion and Herbold Meckesheim to benefit customers. From mechanical processing – shredding, washing, separating, drying and agglomerating of plastics – to bulk material handling as well as feeding and extrusion all the way to compounding and pelletizing, the systems that both companies have developed together cover the entire process chain for reclaiming plastics. Moreover, the plastics industry will profit from this cumulative expertise thanks to their combined global sales and service network.
Experience PET recycling live
PET recycling is one example that illustrates how Coperion will be able to implement a complete system for plastics recycling in the future. As the plastics industry makes advances towards a circular economy, PET plays an ever more important role due to its increasing use in disposable and reusable bottles and its recovery through deposit systems, along with other factors. This material possesses outstanding recycling properties, regardless of whether it is to be recycled in bottle-to-bottle, bottle-to-film/sheet, or bottle-to-fiber processes, or whether it comes from other product streams.
Complete PET recycling solutions from Coperion offer throughput performance of up to ten tons per hour. The quality of PET recyclate manufactured using Coperion recycling technology and decontaminated in an SSP (Solid State Polycondensation) reactor is so high that it is approved by the FDA for direct contact with food.
One unique feature is that virgin material and various recyclates – such as regrind, agglomerates, or flakes – can be processed together, even if they exhibit different IV (Intrinsic Viscosity) values.
