Dag van het Klimaatakkoord

Op de Dag van het Klimaatakkoord praten we met experts over de slagingskans van innovaties voor de energietransitie. Hoe kunnen we de uitstoot van broeikasgassen sneller omlaag brengen?

Dutch industry has a major ambition: to be fully sustainable by 2050, and to meet tough intermediate targets along the way, most particularly in 2030. To do this, it will need to play a leading transformational role. 

But let’s face it: society at large may have some qualms about industry having such a key role. So industry will need to show that it recognizes fully what’s at stake, and that it’s ready to make the investments required and work with stakeholders across the board to make the energy transition happen. 

“We should see heavy industry, not as a big bad polluter, but as an indispensable partner in building a green future.…The Netherlands must pursue an active policy to green heavy industry. It’s time for a green industry policy.”

Evert Nieuwenhuis

To explore these – and other – urgent issues at this watershed moment, we’re inviting representatives from the world of government and politics, as well as from NGOs, SMEs, and industry to share their points of view and join the conversation at our annual ISPT Conference on November 2. The theme this year is “Industry in Society”. 

Now that COVID-19 restrictions have been relaxed, the ISPT Conference will once again be in-person: please be welcome at the Prodentfabriek, a major event complex in the heart of Amersfoort. 

ISPT Conference 2021

Part of the program will be in Dutch, though of course questions can be put in English, and every effort will be made to accommodate those who would prefer to communicate in English.

What to expect: ISPT Conference 2021

We’re pleased to line up an impressive roster of speakers. The ISPT Conference will be moderated by Dick Weiffenbach, Managing Director at Netbeheer Nederland.

After Dick’s opening remarks, the program will kick off with a video on green industry policy by journalist and researcher Evert Nieuwenhuis, who has worked with the scientific branch of the political party GroenLinks on an ambitious climate plan. 

After that you are invited at 3 roundtables where discussions will be commented on by Jan Terlouw, the well-known physicist, former politician, and writer of essays, thrillers, and children’s books. Since as far back as the 1970s, Jan has been actively involved in nature conservation, and in recent years he has been a committed advocate of a greener earth.

NPS17 is organized by Delft Process Technology Institute (DPTI). The symposium will be held on April 4th and 5th 2022 on the campus of Delft University of Technology, Delft, The Netherlands. Save the dates now!

My name is Carlo Giuseppe Bertinetto and I am a researcher in ISPT’s project Towards improved circularity of polyolefin-based packaging.I believe that chemometrics, a field that combines data science with chemical and physical knowledge, can greatly contribute to more efficient processes and a more sustainable future. I started working on this topic about 15 years ago, when I was invited to choose this topic for my M.Sc. thesis mainly because nobody else in my course was attracted to it. At that time, data science was not as trendy as nowadays, but soon I realized how useful and fun it can be! I stuck to it ever since.


I obtained a PhD in Physical Chemistry at the University of Pisa in 2010 with a thesis on predicting molecular properties using Recursive Neural Networks. Between 2011-2018 I was a postdoc researcher at Aalto University (Finland), with a stay at the University of Barcelona in 2016, conducting statistical and mathematical modelling of analytical data, with an emphasis on spectral and microscopic imaging. In 2018 I started a postdoc researcher position at Radboud University and have been working on the analysis of various types of data from the industrial, medical and biological fields.

Project and research

I was invited to join by my supervisor because the project fits well with my previous expertise and is aligned to my interests. The part of my research that best applies to this project is the use of blind unmixing methods, also named Multivariate Curve Resolution, to disentangle the spectral signals coming from different substances in a given sample. This can directly be employed to determine which materials are present in an image and where. In my past research I successfully applied these methods to other kinds of data, but the approach is basically the same. I also have experience in other types of machine learning such as supervised linear and non-linear models that could prove to be useful for this project.

In the coming year I expect to test and implement machine learning methods to distinguish different materials, drawing from my experience of similar imaging studies that I did in the past.

The industry is in transition. How can current employees find their way in a changing environment? And what is expected of the future generation of smart employees? During Deltavisie we want to gain more insight into this through talks and discussions.

At ISPT we believe that radical change can be achieved through technological innovation and cooperation. An important part of our work is supporting and promoting SMEs and startups by connecting them to the industry. This with the goal to stimulate the breakthrough innovations that are desperately needed to transform to a CO2-neutral industry.

Funding opportunities

For SMEs and startups the funding opportunities are enormous, whereas the application procedures and expectations are often unclear. To aid SMEs and startups in the process we are organizing an exclusive online workshop on the 24th of June from 11:00 – 12:00. During the workshop we will provide hands-on guidance on grant schemes and successful applications, regulations and subsidies. Experts Tjeerd Jongsma (ISPT) and Rob Kreiter (TKI) will be present for a discussion about expectations from grant providers, the ISPT network and the TKI.

How can I register?

Send an email to Dewi Mooij at dewi.mooij@ispt.eu to register. You will receive a link to participate on Wednesday June 23 the latest.

Sign up before June 18. This is a small-scale webinar and have set a maximum of 30 participants. Participation in the workshop is free of charge. No-shows are not appreciated.

ADCHEM 2021 will bring together researchers and practitioners from all over the world, to facilitate discussions of recent developments in the control and modeling of chemical, biomedical, and other process systems.

During the April 29 sessions of the Circular Plastics Conference 2021 policymakers and technology providers took the stage to formulate the opportunities to create a circular plastics value chain. The session on chemical depolymerization and solvolysis was led by Dr. Jan Jager (NHL Stenden), and shows that the existence of innovative technologies is not the issue at stake. Additionally, Anne-Gaëlle Collot from PlasticsEurope led an inspiring session on the different initiatives on European policy level and the importance of broad pan-European cooperation and citizen engagement.

Chemical depolymerization and solvolysis

What are the promising technologies that could push the transition towards a circular plastics value chain? During the session on chemical depolymerization and solvolysis, representatives of global technology providers presented innovative technologies that are close to enter the market and can largely contribute to making plastics circular.

Cure Technology: using glycolysis as a base depolymerization technology

Chief Commercial Officer Josse Kunst introduced the PET-recycling start-up Cure Technology. Using glycolysis as a base depolymerization technology, they operate a technique which has a proven low LCA for rPET compared to virgin PET. Josse indicated that the separation/purification process is the most challenging part of the whole operation, and that they are working on a new technology. Cure plans to have a full commercial operation up and running by 2024.

Axens: depolymerisation technologies for a wide range of PET-waste

Axens, an international provider of advanced technologies, has extensive experience with scaling up new technologies using risk mitigation strategies. Their Technology Development Manager, Fabian Lambert, presented their PET-recycling pilot with several purification technologies, which are critical for the operation. Together with Jeplan, a Japanese company, they will develop their depolymerisation technologies further for a wide range of PET-waste, including textiles. They are aiming for commercialization by 2023.

SoliQz: more effective and less energy consuming purification process through melt crystallization

Dirk Verdoes from SoliQz, a company that makes solid-liquid separation and purification process more effective, explained that purification, which is very important for solvolysis/depolymerization, could be done with a new technology based on melt crystallization. This technology is a relatively low energy consuming principle, where crystals, which are very pure (99-99.9%), are formed in a hydraulic wash column. This technology could give huge improvements in solvent based operations like solvolysis, as well as providing a low energy alternative for current technologies.

Ineos Styrolution: foodgrade recycling of polystyrene

A different feedstock for recycling is polystyrene (PS). This is addressed by Norbert Niessner from Ineos Styrolution, a global styrenics supplier. They are working on the depolymerization of both Acrylonitrile Butadiene Styrene (ABS) and PS. Based on the composition of PS, sorting from post-consumer waste streams has proven to be very fit for recycling as it can result in a 99.9% pure stream. Also, PS can be effectively depolymerized and polymerized again. Norbert showed an example where yoghurt cups were reprocessed into yoghurt cups, which were fit for food application. They are now working on the final food approval for this process.

Delaying factors

It is fair to say that chemical depolymerization of polycondensates and styrenicis are developing fast and have large potential to help making these types of plastics circular. The technologies are already here, so what is still hampering the developments at this moment?

According to Norbert good sorting is the key for success in the PS value chain. Ineos Styrolution is working with sorting technology provider Tomra to improve this. Florian insisted that full collection is important, as this is not implemented in most European countries. And Josse added that directives in relation to the application of minimum amounts of recyclates in various applications would facilitate this enormously. This is being worked at on country as well as European level with ministries and companies, but it is a very slow process.

Product stewardship; the way ahead

Anne-Gaëlle Collot moderated the session where the key European policies and initiatives on improving plastics recycling and making a circular value chain were presented.

Laure Baillargeon


Irene Mora


Kamal Azrague


Rob Rutjes


DG GROW: from product-driven to material-driven policies

Laure Baillargeon from the Directorate-General for Internal Market, Industry, Entrepreneurship and SMEs (DG GROW) kicked off the session. She elaborated on how the European Commission changed the adoption of the EU Plastics Strategy from elaborating policies around products, to developing policies around a material and the complexities associated with that. The latter included how to apply the concept of stewardship to that process. Baillargeon presented the objective of the Circular Plastics Alliance (CPA) and its special features, such as cross sectoral and voluntary initiatives that cover the entire value chain with the objective to give “everyone that matters” a seat at the table and give them ownership of the process. In addition, she presented the structure of the CPA, which is reflective of this approach and aims to create cross-sectoral interlinkages. Baillargeon also underlined that the European Commission acts as Secretariat of the CPA and was responsible for setting the political and legislative objective of the CPA (10MT recycled plastic by 2025).

PlastiCircle: the importance of citizen and stakeholder engagement

Irene Mora (PlasticsEurope) and Kamal Azrague (Sintef) presented the EU Horizon 2020 project PlastiCircle that aims to develop and implement a holistic pan-European approach to increase the recycling rate of packaging waste. They shared their experiences on launching pilot projects in three different European cities and stressed the importance of citizen engagement in the process. Among the lessons learned are the positive experience of sharing perspectives and being open to the views of other stakeholders, mainly municipalities and citizens, and the need to create an end market for recycled packaging for the pilot to be effective in the end.

Operation Clean Sweep: tackling the issue of marine pollution

Rob Rutjes from LyondellBasell presented the issue of marine pollution and the industry’s initiative to tackle pellets loss: Operation Clean Sweep (OCS). Beyond explaining the main features of the program, he also provided information on the Certification Scheme currently under development with the value chain. Moving forward, it will be key to develop an accurate methodology to assess pellet losses and to engage an even bigger number of companies in the program along the entire value chain, including smaller value chain partners.

EU perspective for broad cooperation and alignment

During the panel discussion the speakers spoke about the lessons learned from engaging in their respective projects. Laure underlined the participation of other member states in the CPA could provide valuable input. Furthermore, each presenter emphasized the importance of broad cooperation and alignment and that this can only be done in an EU perspective which is the reason the CPA is pivotal to get plastics circular.

How to make plastics fully circular? The answer to this question is multifaceted and affects many stakeholders. Still, it is important to bring this all together and collaborate. In the past few months, the circular plastics community gathered in expert sessions at the Circular Plastics Conference 2021, sharing insights and learnings. On May 20 we conclude with concrete steps ahead to achieve this all-important goal. Join us for an enriching discussion and share your input on the roadmap.

What are key examples of current scientific progress in mechanical recycling of polymers in Western Europe and how can we link it to practical applications? And what are the criteria for circularity needed in the EPR systems of tomorrow? Jaap den Doelder (TU Eindhoven) and Graham Houlder (CEFLEX) took the stage in the April 8 parallel sessions of the Circular Plastics Conference 2021 to address these issues. Together with their panel experts, they answered the questions of today to create the world of tomorrow: making a fully circular plastic value chain.

Mechanical recycling: food grade focus ahead

The session moderated by Jaap den Doelder featured industrial and academic speakers, discussing technical solutions and dilemmas to get plastics streams circular by mechanical recycling technology. Through the inspiring moderation of Jaap den Doelder – who also introduced polls to the audience to understand how they connected to the presented topics – there was a good mix of presentation and interaction with the audience.


Jan Bruys


Ruben Demets

Ghent University

Jan Kolijn


Mark Roelands


Jaap introduced Ruben Demets from Ghent University first, and Demets addressed the complexity of thermoplastics based on their composition and properties. Characterization of the various plastics is important to further rationalize re-processing towards specific applications, he argued.

In the next presentation by Jan Kolijn (Tusti) it was made clear that all players active in a value chain play a part in the circle to decide what type of recycled quality is needed and produced. He introduced experiences from the Prolifex project, where such a collaboration resulted in reaching promising results.

Mark Roelands (TNO) explained that dissolution technology – the technique to use specific solvents to solve and separate specific polymers from a (mixed) plastics stream – has a bright future ahead for various types of plastics. He noted that already quite some industrial activity is present in this field, where this technology has a lot of added value for mechanical recycling of plastics.

Extrusion has always been the preferred process to make both virgin as well as recycled granulated plastics. More added value can be reached by using new stripping or degassing steps in the melting phase of various types of plastics, as was explained by Jan Bruys (KraussMaffei). Cascade processing, a ”train” of various and successive processes, including extrusion, is being developed for more processing routes and will be part of the future of recycled plastics, according to Bruys.

The discussion about these key examples of mechanical recycling show that the knowledge is already there. However, the challenges lie in joining forces in order to change old habits and revalue what we expect from recycled plastics.

Status and developments in Extended Producer Responsibility (EPR) systems

Extended Producer Responsibility (EPR) systems play an essential role in meeting today’s recycling targets. They will play an even more important and central role in a fully circular plastics economy.

The dedicated session led by Graham Houlder (CEFLEX) discussed the way EPR can make this role reality. EPR is an enabling tool through which producers (both brand owners and retailers) can fulfill their individual legal responsibility for the end-of-life management of their used products/packaging. This includes financial and – usually – operational responsibility for the collection, sorting and treating of these products/packaging when they reach the end of their life and enter the waste stream.


Mike Jefferson


Feliks Bezati  


Joachim Quoden


EPR systems are already in place in most European countries, but with a lot of differences in how they have been implemented nationally. Speakers Joachim Quoden (EXPRA), Mike Jefferson (CEFLEX), and Feliks Bezati (Mars) discussed the ways EPR systems will need to develop in the future to operate effectively in a circular economy.

The CEFLEX EPR Criteria for Circularity for each of the four areas (operational, financial, communication, governance) were presented and a discussion followed exploring how EPR systems will need to evolve to drive improved collection, sorting and recycling levels and infrastructure, and to ensure that these new systems are financially sustainable and can be used to encourage more circular packaging design through tools like eco-modulation.

Feliks Bezati presented that while brand owners have full control over the design of products, they currently have little influence on which types of packaging are collected for recycling in a country despite paying EPR fees on all packaging materials. He singled out including flexible packaging, a very important packaging format for Mars, which is still not collected and recycled widely in many European countries. Bezati emphasized that brand owners like Mars, are fully supportive of well managed EPR systems and that they are willing to increase their EPR contributions provided these are used to support returning those packaging formats like flexible packaging.

The main conclusion from the session was that EPR systems will play a vital and important coordinating role in the emerging circular economy for plastic packaging materials. To make this happen, important structural changes will be needed and, most importantly, these changes will need the support of the whole value chain to be realized in time for plastic packaging to be increasingly circular by 2025.

This was the fourth conference day of the Circular Plastics Conference 2021. If you are registered you get access to presentations and recordings on the Networkapp platform. The next and final parallel sessions take place on April 29. In addition, the final keynote session takes place on May 20.

Concerted action to tackle plastic waste and ensure its recycling

The Circular Plastics Initiative aims to make plastics fully circular. To achieve this, it brings together organisations from every phase in the lifecycle of plastics. In its newest Integrated approach towards Recycling of Plastics (InReP) project, waste collectors, sorters & recyclers, chemical industry, end users and knowledge institutions join forces to develop technological solutions that make recycled materials which meet the quality standards of industry.

Plastics are a valuable material with functionalities that serve a sustainable society. They are light-weight, transparent and strong. They protect food from going to waste. They make vehicles lighter, which reduces the amount of CO₂ vehicles emit. And they make products durable. At the downside, plastic litter can be found all around the globe and destructs habitats, while the production relies on fossil resources and contributes to greenhouse gas emissions. This calls for concerted action to tackle plastic waste and ensure its recycling.

ISPT Team - Ronald Korstanje

“By working in an integrated approach, we develop value added and meaningful innovations that contribute to the whole system of plastics recycling.”

Ronald Korstanje, Program Director of the Circular Plastics Initiative

Most food packaging cannot be recycled to food packaging

There are many different types of plastic that need to be sorted by type to guarantee high quality recycled materials. The situation now is that most of the plastic waste gets incinerated. The part that does get recycled often does not allow high-quality reuse. For example, only PET plastics from bottles can now be recycled again to PET bottles for food packaging. Other packaging plastics and packaging types are not suited to be recycled to food packaging.

To ensure proper recycling we need to develop new and environmentally friendly sorting and recycling technologies. When the recycling process is taken into account in the design phase of plastic packaging and products, the collection, sorting and recycling processes that follow can be adjusted accordingly. This will allow for plastic waste to be made into high quality recycled materials and be reused in production processes.

Boost for the availability of high-quality recycled materials

The InReP project focuses on the two dominating polymer types – polyolefins (PE/PP) and PET. By developing various technologies and progressing the processes from sorting to recycling of plastics, InReP will boost the availability of high-quality recycled materials which fits the industrial needs.
