Finalists for the 2022 RISE® Innovation Award:
Cat Litter Made from Recycled Nappies – DiaperRecycle
DiaperRecycle has developed technology to recycle used diapers into cat litter. The aim of the company is to make an environmental impact and decrease the climate changing emissions of diaper waste. They’re diverting used diapers (used in households and businesses such as elder care) from landfill, separating the plastic and fiber and making cat litter. The plastic is prepared for recycling by plastics recyclers. The cat litter product is made by DiaperRecycle from the super absorbent fiber of diapers; it’s highly absorbent and flushable.

Biodegradable Diaper Components – Gottlieb Binder GmbH & Co. KG
Together, Avgol and Binder take on the challenge of disposable absorbent articles for the good of future generations and came up with sustainable diaper components. The technologies used are based on biotransformation technology, which makes it possible to achieve more sustainable products by supporting recycling and providing an alternative route for non-recyclable/fugitive waste management.

• An innovative European project to process and recycle plastic textile waste
• A partnership to reach the objectives set by the European Union in reducing CO2 emissions by 2030
• A unique consortium rallying 16 public and private European organizations working together for more circular economy

Carbios joined WhiteCycle, a project coordinated by Michelin, which was launched in July 2022. Its main goal is to develop a circular solution to convert complex^[1] waste containing textile made of plastic into products with high added value. Co-funded by Horizon Europe, the European Union’s research and innovation program, this unprecedented public/private European partnership includes 16 organizations and will run for four years.
 
WhiteCycle envisions that by 2030 the uptake and deployment of its circular solution will lead to the annual recycling of more than 2 million tons of the third most widely used plastic in the world, PET^[2]. This project should prevent landfilling or incineration of more than 1.8 million tons of that plastic each year. Also, it should enable reduction of CO2 emissions by around 2 million tons.
 
Complex waste containing textile (PET) from end-of-life tyres, hoses and multilayer clothes are currently difficult to recycle, but could soon become recyclable thanks to the project outcomes. Raw material from PET plastic waste could go back into creation of high-performance products, through a circular and viable value chain.
 
Public and private European organizations are combining their scientific and industrial expertises:

• industrial partners (Michelin, Mandals, KORDSA);
• cross-sector partnership (Inditex)
• waste management companies (Synergies TLC, ESTATO);
• intelligent monitoring systems for sorting (IRIS);
• biological recycling SME (Carbios);
• product life cycle analysis company (IPOINT);
• university, expert in FAIR data management (HVL);
• universities, research and technology organizations (PPRIME – Université de Poitiers/CNRS, DITF, IFTH, ERASME);
• industry cluster (Axelera);
• project management consulting company (Dynergie).

 
The consortium will develop new processes required throughout the industrial value chain:

• Innovative sorting technologies, to enable significant increase of the PET plastic content of complex waste streams in order to better process them;
• A pre-treatment for recuperated PET plastic content, followed by a breakthrough recycling enzyme-based process to decompose it into pure monomers in a sustainable way;
• Repolymerization of the recycled monomers into like new plastic;
• Fabrication and quality verification of the new products made of recycled plastic materials

 
WhiteCycle has a global budget of nearly 9.6 million euros and receives European funding in the amount of nearly 7.1 million euros. The consortium’s partners are based in five countries (France, Spain, Germany, Norway and Turkey). Coordinated by Michelin, it has an effective governance system involving a steering committee, an advisory board and a technical support committee.

• Exceptional achievement of research work on the use of Nuclear Magnetic Resonance (NMR) spectroscopy for understanding PET depolymerization enzymes

Carbios (Euronext Growth Paris: ALCRB), a pioneer in the development of enzymatic solutions dedicated to the end-of-life of plastic and textile polymers, announces the publication of an article entitled “An NMR look at an engineered PET depolymerase” in the scientific journal Biophysical Journal.

The article describes the use of Nuclear Magnetic Resonance (NMR) spectroscopy to study the thermal stability of PET depolymerization enzymes and the mechanism of adsorption of the enzyme on the polymer. This innovative approach, which required months of development, is a world first and opens up new ways of improving these enzymes. This publication confirms Carbios' international lead in the development of the most efficient enzymes for the depolymerization and recycling of plastics.

Prof. Alain Marty, Chief Scientific Officer of Carbios and co-author of the article, explains: “ Nearly 25 researchers are currently working on our unique enzymatic technology. It is based on academic collaborations with the world's leading experts in their fields..”

Dr. Guy Lippens, CNRS Research Director and co-author of the artcle, adds: “Nuclear Magnetic Resonance (NMR) is an extraordinary biophysical technique for visualizing an enzyme directly in solution. Our study is the first to use NMR as a complementary technique to crystallography and molecular modeling to observe a PETase. This gives new perspectives to better understand the functioning of these enzymes and it makes it possible to imagine new ways of improving these enzymes. ”

• Sustainability Report 2021 combines financial and non-financial performance indicators
• 2011-2021: 60% reduction in greenhouse gas emissions per metric ton produced. 51.7% renewable source energy achieved
• ESG criteria (environmental impact (E), social values (S), organizational governance (G)) determine sustainability strategy

The new RadiciGroup Sustainability Report has been published. With the goal of continuous improvement, the 2021 report has a broader reporting boundary compared to prior years and takes into consideration all the Group companies, including sales and service companies. Over 30 sites located across Asia, North America, South America and Europe have provided their 2021 data on economic, social and environmental performance.

Not only indicators of a financial nature but also measures of environmental impact (E), social values (S) and good organizational governance (G): the latter so-called ESG criteria have become a priority for RadiciGroup, which is preparing for the new European Union non-financial reporting directive in order to contribute to the transition towards a fully sustainable economic system and increase the value of its companies.

On the environmental front, the themes of climate change and decarbonization are RadiciGroup priorities and part of a policy aimed at the uncoupling of growth and resource usage. The Group undertakes to lower emissions from production and choose limited-impact energy sources. This commitment is confirmed by the numbers: in the 2011-2021 period, total emissions per metric ton produced were reduced by 60%, while renewable source energy used by the Group reached 51.7%. Specific investments to decrease environmental impact are ongoing: in 2021, EUR 3.1 million were allocated to introduce best available techniques and improve emissions abatement and energy efficiency.

RadiciGroup promotes professional growth by valuing competence and investment in training: Group training hours once again rose after the pandemic period from 36,000 hours in 2020 to 46,000 hours in 2021. The training method was often a hybrid, taking advantage of aspects experimented with during the pandemic, that is, less traveling and use of facilities in favour of higher groupwide attendance, without the need for participation limits. Fifty-five percent of total training hours was dedicated to health and safety, which has yielded positive results based on the related indicators.

Angelo Radici, president of RadiciGroup: “Today, the United Nations 2030 Agenda for Sustainable Development is our main guideline on sustainability issues. It shows us an ambitious scenario and urges us to confront a multitude of challenges that affect our enterprise from every point of view. We try to be quick to react and tenacious, staying faithful to our roots and our style, but expanding our perspective to become increasingly more competitive and proactive in the businesses we are engaged in. From the viewpoint of achieving less environmental impact in the future, we propose to be an enabler and facilitator for our stakeholders on themes such as the circular economy, where we see ourselves as protagonists in ecodesign and recycling, as well as innovation, which we put at the service of anyone who is processing and using our products, so as to offer real sustainability solutions together.”

International technology group ANDRITZ has established a new inline Wetlace™ CP pilot line with an original design at its center of competence in Montbonnot, France. The line combines both spunlace and wetlaid technologies.

From now on, partners will be able to conduct trials and test all options available for wipes production – from carded staple fibers to pulp and various combinations thereof. The combination of both spunlace and wetlaid technologies offers to move forward to more sustainable options while maintaining a high level of product quality, in particular by achieving high CD strength and good linting properties.

Over the past few decades, ANDRITZ has continued to innovate with various nonwoven processes, like spunlace, WetlaceTM and Wetlace™ CP, with the aim of optimizing the use of raw materials and focusing on sustainability by reducing the synthetic fiber content. Facing the growing demand for bio-wipes in parallel with enforcement of the EU’s single-use plastics directive last year, ANDRITZ has decided to support its customers making their investment decisions.

The Montbonnot pilot line has been rebuilt to integrate the new headbox inside the spunlace line. Pulp can be fed in directly and entangled with carded staple fibers to produce unique nonwoven fabrics designed for end uses as bio-wipes.

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.

The sustainable collaboration and innovation between Indorama Ventures (IVL), Auping and TWE Group presented a certified cradle to cradle process for mattress components across nonwoven applications, at Techtextil, Frankfurt, 21st to 24th June 2022.

Using circular research and design, the industry partnership between IVL Mullagh (Ireland), Auping and TWE Group has resulted in a perpetual, sustainable economic business model, for manufacturers globally. The inclusion of safe raw materials within mattress manufacturing allows the materials to be easily disassembled at the product’s end of use in order to be further reused as same components or recycled into new raw material at the same quality level, to enable versatile textile applications.

Designed for disassembly to optimize the use of existing resources, reduce carbon footprint and support customer objectives all along their customers’ supply chain. This circular industry collaboration begins with design, where the mattress is constructed using only two different base materials, 100% PET polyester textiles and steel wire pocket springs connected with Niaga®️, a non toxic reversible adhesive, making the mattress easy to disassemble and recover.

IVL, Auping and TWE’s shared vision for a better world is demonstrated through their connected and innovative circularity that helps to close the loop. Auping collects, sorts and separates the collected fabrics, which then go to IVL Mullagh for processing, melting and extrusion to form polyester staple fiber. These staple fibers are then converted by TWE Group into nonwovens for use in Auping’s Evolve mattress, a fully circular mattress. Following the end of mattress use, the material recovery process simply starts again.

Auping estimates that annually more than 40 million mattresses are disposed of in Europe alone, the majority of which are incinerated. Their take back system in the Netherlands ensures that when their new mattress is delivered, the old mattress is retrieved and recycled, irrespective of the brand, ensuring existing materials are continually optimized, diverted from landfill and kept in use to achieve a circular economy.
