From the Sector

CARBIOS and Hündgen Entsorgungs GmbH & Co. KG (Hündgen), a waste management expert in logistics, sorting services and the recycling of recyclable materials from waste mixtures, announce the signing of a non-binding Memorandum of Understanding relating to the sourcing, preparation and recycling of 15kt/year of post-consumer PET waste using CARBIOS’ biorecycling technology at its first commercial plant in Longlaville, from end 2026.

The partnership will leverage Hündgen’s expertise and network in the sourcing and preparation of light packaging waste collected from German households. This PET waste will be prepared into flakes ready for biorecycling using CARBIOS’ enzymatic depolymerization technology, which produces food-grade PTA and MEG, further re-polymerized into PET.

The supply partnership with Hündgen contributes to securing the majority of CARBIOS’ feedstock needs for its first commercial plant in Longlaville, France. This plant will have a 50kt/year capacity when it will be fully operational and is currently under construction. This latest sourcing announcement comes in addition to previously announced agreements, such as with Landbell Group for food trays from Germany, and the winning CITEO tender for trays in France. The location of the Longlaville plant is strategically close to nearby waste supplies in Belgium, Germany and Luxembourg.

Through its enzymatic depolymerization process, CARBIOS can process all types of PET waste, including waste that cannot be recycled with current technologies. Multilayered, colored, and opaque packaging waste as well as polyester textile waste now have circular recycling solutions.

Carbios and L’Oréal have won the “Pioneer Awards” in the Industry category, presented by the Solar Impulse Foundation at the first World Alliance Summit. This prize was awarded to Carbios for its enzymatic PET recycling solution, labeled “Efficient Solution” by the Solar Impulse Foundation since 2019, and to L’Oréal for using this technology for the first time in a cosmetics bottle prototype. Carbios’ solution offers brands an alternative to petro-sourced plastic that helps them meet their sustainability commitments. This advancement paves the way for future applications in other sectors such as packaging, food and beverage, and textiles.

Carbios and L’Oréal: a long-term collaboration
Since 2017, Carbios and L’Oréal have been working together with a shared vision of accelerating the transition to a circular economy for plastic. In 2017, both companies created a Consortium to improve the recyclability and circularity of PET packaging.  Nestlé Waters, PepsiCo and Suntory Beverage & Food Europe joined this Consortium in 2019 to scale up Carbios’ innovation. The world’s first enzymatically recycled PET packaging was made in 2021 using Carbios’ biorecycling process. The world’s first PET biorecycling plant is scheduled to be commissioned in 2025. In parallel, Carbios is rolling out its technology internationally through licensing agreements.

The environmental benefits of biorecycling developed by Carbios
Recent life-cycle analyses^[1] show a 57% reduction in CO₂ emissions compared with the production of virgin plastic^[2], and for every tonne of recycled PET produced, 1.3 tonnes of petrol are avoided. Compared with conventional recycling, enzymatic recycling is 4 times more circular (calculated according to the Ellen MacArthur Foundation’s Material Circularity Indicator). Thanks to its highly selective enzyme, optimized for efficient PET degradation, Carbios’ depolymerization process can process all types of PET waste, including colored, multilayer or textile waste that cannot be recycled using current technologies. Furthermore, the two monomers produced (PTA and MEG) make it possible to recreate recycled PET products of identical quality to virgin ones, and suitable for food contact.

Carbios will receive grants totaling €54 million from French State via France 2030 and Grand-Est Region to finance construction of world’s first PET biorecycling plant and accelerate R&D activities

Carbios announces that its project has been selected by the French State for funding of €30 million from the French State as part of the investment plan France 2030, and €12.5 million from the Grand-Est Region.  The implementation of this funding is conditional to the European Commission’s approval of the corresponding state aid scheme, followed by the conclusion of national aid agreements. As part of the national call for projects on “Plastics Recycling” operated by ADEME^[1], Carbios’ project to finalize the industrialization of its unique PET biorecycling process has been selected. The reference plant in Longlaville in the Grand-Est region will be the world’s first PET biorecycling plant and is due for commissioning in 2025. This plant will make it possible to relocate to France the production of the two basic components of PET, PTA and MEG^[2], both derived from the Carbios process.

Carbios also announces that it has been granted total funding of €11.4 million from the French State as part of France 2030, of which €8.2 million directly for Carbios (€5 million in repayable advances) and €3.2 million for its academic partners INRAE^[3], INSA^[4] and CNRS^[5] via the TWB^[6] and TBI^[7] joint service and research units. This funding will enable to continue its research into the optimization and continuous improvement of Carbios’ enzymatic technologies.

The plant will secure the sales of the first volumes of recycled PET produced with Carbios’ technology, and to offer its partners recycled PET of the same quality as virgin PET. Once the necessary permits have been obtained, which should be granted by the end of 2023, in line with the announced start of construction before the end of the year, the plant is scheduled to be commissioned in 2025. This will be followed by a period of ramp-up to full capacity. The plant will have a nominal processing capacity of 50,000 tonnes of PET waste per year, equivalent to 2 billion bottles or 2.5 billion food trays.

Selection for funding by the French State through France 2030 and the Grand-Est Region complements the recent announcement of an exclusive, long-term partnership with Novozymes^[8], a leader in enzyme production, one of the main aims is to ensure the supply of enzymes to Carbios’ Longlaville plant and future licensed plants. In addition, Carbios recently secured a first supply source for its future plant by winning part of the CITEO tender for the biorecycling of multilayer trays^[9].

With the goal of making recycling of lightweight, high-volume fiber and flake recyclate much more economical and, in some cases even possible, Coperion has developed a new version of its ZS-B side feeder. Using the innovative ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into Coperion’s ZSK twin screw extruder and be concurrently recycled and compounded.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

Increased Throughput in Numbers
With a ZSK 58 Mc18 twin screw extruder, the throughput increase and thus the potential of the new ZS-B MEGAfeed becomes very clear. When recycling PA fibers with a bulk density of ~40-50 kg/m3, throughputs of 70 kg/h were previously achieved using conventional equipment. When the PA fibers were fed into the ZSK extruder using the ZS-B MEGAfeed, throughputs increased about fourteenfold to 1,000 kg/h. Similar results were achieved recycling carbon fibers with a bulk density of ~50-70 kg/m3; in this case, throughputs increased from 50 kg/h to 2,500 kg/h using the ZS-B MEGAfeed. When recycling PCR (Post-Consumer Recycled) flakes, throughputs increased from 50 kg/h to 700 kg/h, and from 80 kg/h to 1,300 kg/h with multilayer film flakes.

Key to Economical Recycling of A Wide Variety of Plastics
Plastics previously considered not recyclable are becoming a valuable raw material using the new Coperion ZS-B MEGAfeed. For example, PCR flakes or recyclate from carbon fiber-reinforced plastics can now be fed into the ZSK extruder at high feed rates and recycled economically.

In the case of mechanical upcycling, upstream processes necessary for compounding, such as compacting, melting and agglomeration, are completely eliminated using the ZS-B MEGAfeed technology. In this recycling process, flakes and fibers can be fed directly into the ZSK extruder, where they are melted, compounded, devolatilized, and filtered in a single step. In so doing, both investment costs and energy consumption drop. The production process becomes significantly more efficient. Moreover, the thermal product stress is reduced and recyclate quality increases.

Even when recycling PET, the feed rate is no longer a limiting factor. With the ZS-B MEGAfeed, PET flakes and fibers can be fed into the ZSK twin screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the highest degree of profitability.

The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor.

Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates.

• "Dibella up" records its first big success

Aalten, "Dibella up" is bearing its first fruits. Since the launch of the recycling concept initiated in August 2020, six tons of sorted laundry items have already been returned to Dibella and converted into new ones by the company in farsighted reuse projects. The customer who has been involved in the project from the very beginning is Lamme Textielbeheer from Nederhorst den Berg. The Dutch textile service provider sees the initiative as an important measure for more appreciation of resources.

Dibella has taken the closed-loop approach of the textile service as a model and has taken a step towards a completely closed cycle with the "Dibella up" project. The system includes unlimited reuse and recycling of the fibre raw materials bound in the textiles. To this end, the company's own textile qualities, which are selected from laundries, are taken back and passed on to selected upcycling projects. Polyester-cotton blended fabrics are processed there into high-quality bags. Pure natural fibre textiles as well as blended fabrics with at least 50 percent cotton are chemically converted into an important raw material for cellulose fibre production, while the remaining polyester is still being thermally recycled for technical reasons.

Six tons of laundry from the Netherlands

Lamme Textielbeheer was immediately enthusiastic about the "Dibella up" initiative. The committed company has been involved in various Dibella sustainability projects for many years and recognises the future-oriented character of the new project. "Our will to cooperate was immediately clear after Dibella's managing director Ralf Hellmann presented the upcycling project, because we see it as an important measure for the prudent use of resources," reports Jan Lamme, managing director of the company of the same name. "Within a very short period of time, we therefore jointly started to take back our discarded, no longer usable old textiles. In this way, we have already been able to return six tonnes of laundry for a new product cycle. This corresponds exactly to our idea of upcycling!". "Dibella provides stable, reusable cartons for shipping," says a delighted Frank David, Lamme's Assistant Operations Manager. "This makes collection much easier for us and we don't have to take any means of transport out of our laundry".

Prepared for the mega-trend of recycling management

Dibella would like to build on the initial joint success and further expand the initiative for a closed textile cycle in the industry. "The awareness of sustainability is high in the textile rental service. But the next mega-trend is already emerging. The future lies in closed-loop recycling. With "Dibella up", we are offering our customers the opportunity to get involved now and make resources usable in the long term. We are happy about every new cooperation partner who appreciates the value of textiles as much as we do".
