Recently, Bill Cooper, senior vice president of strategy and development at chemical recycling company Agilyx, said that if it can reach the appropriate scale, the recycling cost of chemical recycling route may be better than that of corresponding petroleum-based products, which can lead the development of recycled polymers in the futu.
<br/.
However, other market players said Cooper's estimates were too optimistic, recycling polystyrene (PS) is an excellent technology, but the economics are still difficult to compare with petroleum-based products, and it is difficult to save society's replacement action for .
PS can be recycled
PS is recyclable PS is recyclablePS has long been considered a difficult-to-recycle plastic produ.
But a few days ago, Agilyx announced a partnership with Ineos Styrolution and Trinseo to build the first local industrial-scale PS chemical recovery unit in Euro.
This has a good impetus for PS recycli.
Bill Cooper of Agilyx said: “Agilyx is relatively mature in polymer recycling technology, and the flexibility of raw materials has been solv.
Most of the PS waste used in the unit is foamed plastics, such as extruded polystyrene (XPS), expandable polystyrene Styrene (EPS), e.
, but general-purpose polystyrene and high-impact polystyrene (HIPS) can also be us.
In addition, Agilyx can also handle PS waste contaminated with food contamination and other organi.
As of now, the R&D team has A large amount of PS waste is obtained in a variety of industri.
”
However, Cooper acknowledged that while Agilyx was able to process contaminated PS waste, the partially recycled styrene and PS contained significant amounts of other chemicals and polyme.
For example, some grades of HIPS may contain up to 15% polybutadiene, which limits the yield of PS during chemical recycli.
According to Agilyx, the PS recovery unit that has been built and operated in the United States adopts pyrolysis technolo.
PS is heated anaerobic in the reactor, depolymerized into styrene gas, and rapidly cooled to form styrene oil after extracti.
Subsequently, the styrene oil is further cleaned and repolymerized into commercial grade .
Agilyx said the company is continuously expanding its recycling capacity for plasti.
The company is also developing new technologies to expand the amount of waste mixed plastics recovered from landfills, further driving the circular econo.
Saving the market is a big task

Cooper said changing people's perceptions of PS is an uphill battle, and Agilyx has been trying to change people's perceptions of PS to ensure legislation doesn't ban the use of a recyclable materi.
In July, Agilyx said that once the company's plants in Europe were fully operational, it could handle up to 50 tons of PS scrap per d.
The company will expand the plant if need.
However, with Agilyx's current processing capacity, if the average yield of styrene oil is near the high value of 70%, the plant's recoverable styrene capacity is still less than 13,000 tons/ye.
Analysts at ICIS said that in Europe alone, the annual production capacity of styrene plants exceeds 5 million tons, and the processing capacity of the Agilyx plant is less than 5% of the total European styrene production capaci.
Even if Agilyx expands significantly over the next few years, the size gap between recycled and petroleum-based products is completely irresistib.
As PS is difficult to recycle and a series of EU plastic bans are about to take effect, downstream customers in the European PS market have been looking for alternative materials, which has depressed the future expectations of the PS mark.
Distributors pointed out that at present, end product merchants favor alternative materials and consider giving up .
The recycling of PS requires a whole-of-society respon.
But because PS is difficult to recycle, Cooper admits that the social supply of PS scrap is a problem in.
factori.
Agilyx has been leveraging direct-to-consumer delivery, school programs, recycling programs at retail locations, and partnering with municipalities, waste companies, and environmental groups to get more materia.
In addition, the company plans to collaborate more with companies dealing with landfills and waste-to-energy facilities to increase the amount of PS was.
And this is likely to be repeated in European factori.
Commercial success is far from here
Business success is far away Business success is far away Cooper said Agilyx is not too concerned about the price dynamics of styrene or polystyrene in Europe due to the nature of their wo.
But on the important cost issue, Cooper said Agilyx has been able to compete with petroleum-based products without relying on subsidies, credit or other incentiv.
Depending on the path and size of the facility, Agilyx could bring prices down to $30 to $40 a barr.
However, analysts from ICIS said that in the past few months, with the slowdown of macroeconomic growth in the EU, upstream styrene supply continued to grow, and the market demand for derivatives PS and EPS was insufficient, and PS prices fell sharp.
Chemical recycling is still a relatively new technology, and commercial success is far from certa.
The EU is trying to make plastic packaging contain a high proportion of recyclable content by 202
ICIS believes that Agilyx's PS recycling plant is a step in the right direction, but the success of its operations in the EU has yet to be verified by the mark.
Despite the support of European PS producers, the downstream has no time to wait for the PS recycling market to mature due to too urgent policy pressure from the .
