A challenge taken on by RadiciGroup through the Ulysses research project
A pioneering objective: for the first time, to demonstrate the feasibility of industrial-scale production of polyamides (nylon) starting from bio adipic acid obtained from renewable raw materials, including waste oil and by-products of the oil industry. Potential application sectors for the process and products are textile/fashion, automotive, design, electrical and electronics.
This major sustainability-and-circularity-oriented goal has been achieved by RadiciGroup, an Italian multinational headquartered in Bergamo, a world-leading producer of a wide range of chemical intermediates, polymers, high performance engineering polymers and advanced textile solutions. The research was conducted through the Ulysses project and experimentation was performed in collaboration with research centres and universities. Partial funding was received from the Region of Piedmont, within the scope of the “Call for Proposals IR2 (Industrialization of research results)”.
The ambitious, innovative multiyear project was launched in March 2018 and stemmed from RadiciGroup’s desire to increase the sustainability of its products, whilst delivering the same quality and performance as required by product standards. What is more, the Group wanted to meet the demand coming from its various strategic sectors, in line with the European targets for the development of low-emission businesses and a circular economy.
The funding amounted to EUR 6.2 million, of which EUR 1.7 million was contributed as a grant by the Piedmont Region. This investment confirms RadiciGroup’s great commitment to scientific research, which is strongly supported by the Group’s shareholders.
Polyethylene Terephthalate is a thermoplastic polymer that can be opaque or transparent depending on the particular material composition. PET, like other polymers, is made from petroleum hydrocarbons by a reaction of ethylene glycol and terephthalic acid. The PET is polymerized to form long molecular chains, allowing it to make PET bottles later on. Biopolyamides from Waste Oil
What do you understand by polymerization, and why is it important?
Polymerization is a complex process that accounts for many of the differences between batches of produced PET. During polymerization, two types of contaminants are often produced: diethylene glycol and acetaldehyde. Although diethylene glycol is not typically generated in sufficient quantities to damage PET, acetaldehyde can be formed during polymerization and the bottle production process. A high concentration of acetaldehyde in the PET used to make bottles might give the beverage inside an off-taste.
The PET bottle manufacturing process may begin after the plastic has been produced. To guarantee that the plastic is safe for usage, several post-manufacturing tests are performed to confirm that the bottles are not permeable to carbon dioxide (which is essential for bottles that carry soda). Transparency, gloss, shatter resistance, thickness, and pressure resistance are all carefully checked.
‘Sorting Evaluation Protocol for Plastic Packaging’ is a Standard Practice that is geared at evaluating the behaviour of a plastic product during the sorting process in Europe.
Destined to any company that would like to analyse the sortability of its innovative packaging, in line with design for recycling principles.
Recyclability must be verified at every step of a recycling process and assessing plastic packaging’s sortability plays an important role in claiming whether and to what extent a product is recyclable. Following the definition of recyclability, a plastic product can be considered recyclable not only if it is collected, recycled in a commercially available process, used in the manufacture of new products but also when it is sorted into an aggregated stream.
“A holistic approach to recyclability is necessary if we are to make it happen in Europe by 2030”, said Vincent Mooij, Director at SUEZ.circpack®. Martine Brandsma, Director of NTCP added: “The ‘Sorting Protocol for Plastic Packaging’ complements the Recyclability Evaluation Protocols”, she continued “Sharing and implementing best practices and standards in the collection and sorting as well as harmonising them across Europe must follow now if we are to move the needle on design for recycling further.” Biopolyamides from Waste Oil

The industrial demonstration plant will apply Carbios’ C-Zyme recycling process to depolymerize PET. Biopolyamides from Waste Oil
Carbios, a plastic recycling technology provider based in France, has officially launched its industrial demonstration plant operating with its enzymatic recycling technology that the company is calling C-Zyme. The demonstration plant was installed at Carbios’ Cataroux site in Clermont-Ferrand.
Carbios’ C-Zyme recycling process uses an enzyme capable of depolymerizing polyethylene terephthalate (PET). The depolymerized monomers are purified before being repolymerized into PET of comparable quality to virgin PET derived from petrochemicals. The company says this process should enable unlimited recycling of PET as well as the production of 100 percent recycled and 100 percent recyclable PET products that maintain virgin quality throughout the process.

Direct-spun PSF suffers losses again due to less increase than PTA
The reasons behind the robust PTA are rising crude oil and tight supply brought on by advanced maintenance. The PX-PTA spread has also improved moderately.
However, there is a different picture in downstream. The sales of polyester yarn are modest. The prices in Fujian and Jiangxi have increased along with PSF, but in Jiangsu, Zhejiang and northern China, the prices stay flat. As a result, the cash flow of polyester yarn gets compressed. Biopolyamides from Waste Oil
In terms of different products, the cash flow of pure polyester yarn is not reduced much due to small increase in PSF, but that of polyester/cotton yarn has lost much ground due to sharp rise of cotton. It is also reflected in the sales of polyester yarn. The yarn containing more PSF was sold better than that with more cotton, let alone cotton yarn which has been suffered losses.
