Feb 2024 | Structural analysis of petrochemical clusters in Germany: what can be learned for the transformation toward climate neutrality? | Journal of Business Chemistry

The petrochemical industry is among the most relevant sectors from an economic, energetic and climate policy perspective. In Western Europe, production occurs in local chemical parks that form strongly connected and densely integrated regional clusters. This paper analyzes the structural characteristics of the petrochemical system in Germany and investigates three particularly distinct clusters regarding their challenges and chances for a transition towards climate-neutrality. For this, feedstock and energy supply, product portfolios and process integration as well as existing transformation activities are examined. We find that depending on their distinct network characteristics and location, unique and complex strategies are to be mastered for every cluster. Despite the many activities underway, none of them seems to have a strategic network to co-create a tailored defossilization strategy for the cluster - which is the core recommendation of this paper to develop.

Feb 2024 | Plastic recycling stripped naked - from circular product to circular industry with recycling cascade | ChemSusChem | J.-P. Lange, S. R. A. Kersten, S. De Meester, M. C. P. van Eijk, K. Ragaert

This perspective combines various expertise to develop and analyze the concept of technology cascade for recycling waste plastics with the goal of displacing as much fossil crude oil as possible. It thereby presents archetype recycling technologies with their strengths and weaknesses. It then combines them in various cascades to process a representative plastic mix, and determines how much (fossil) naphtha could be displaced and at which energy consumption. The cascades rely on a limited number of parameters that are fully reported in supplementary information and that were used in a simple and transparent spreadsheet model. The calculated results bust several common myths in plastic recycling, e. g. by prioritizing here recycled volume over recycling efficiency, and prioritizing circular industry over circular products . It unravels the energy cost of solvent-based recycling processes, shows the key role of gasification and the possibility to displace up to 70% of the fossil feedstock with recycled carbon, a recycling rate that compares well with that aluminum, steel or paper. It suggests that deeper naphtha displacement would require exorbitant amount of energy. It therefore argues for the need to complement recycling with the use of renewable carbon, e. g. based on biomass, to fully defossilise the plastic industry.

Jan 2024 | Accurate determination of polyethylene (PE) and polypropylene (PP) content in polyolefin blends using machine learning-assisted differential scanning calorimetry (DSC) analysis | Polymer Testing Science Direct Elsevier

Polyethylene (PE) and polypropylene (PP) are among the most recycled polymers. However, these polymers present similar physicochemical characteristics and cross-contamination between them is commonly observed, affecting the quality of the recyclates. With the increasing demand for recycled plastics, understanding the composition of these materials is crucial. Numerous techniques have been introduced in the literature to determine the composition of recycled plastics. An ideal technique should be accessible, cost-efficient, fast, and accurate. Differential Scanning Calorimetry (DSC) emerges as a suitable technique since it analyzes the thermal behavior of compounds under controlled time and temperature conditions, entitling the quantitative determination of each component, e.g., in PE/PP blends. Nevertheless, the existing predictive methods lack accuracy in estimating the composition of PE/PP blends from DSC analysis since the composition of this blend affects its overall crystallinity. This study advances the state-of-the-art regarding this quantification using DSC by implementing a non-linear calibration curve correlating the evolutions of crystallinity with blend composition. Additionally, a machine-learned (ML) model is introduced and validated, achieving high accuracy for the composition determination, presenting an overall mean absolute error as low as 1.0 wt%. Notably, this ML-assisted approach can also quantify the content of subcategory polymers, enhancing its utility.

Jan 2024 | Biomaterials lead to substantial reduction in greenhouse gas emissions but not yet climate neutral | Radbout University

The current debate on the sustainability of bio-based products questions the environmental benefits of replacing fossil- by bio-resources. Here, we analyze the environmental trade-offs of 98 emerging bio-based materials compared to their fossil counterparts, reported in 130 studies. Although greenhouse gas life cycle emissions for emerging bio-based products are on average 45% lower (-52 to -37%; 95% confidence interval), we found a large variation between individual bio-based products with none of them reaching net-zero emissions. Grouped in product categories, reductions in greenhouse gas emissions ranged from 19% (-52 to 35%) for bioadhesives to 73% (-84 to -54%) for biorefinery products. In terms of other environmental impacts, we found evidence for an increase in eutrophication (369%; 163 to 737%), indicating that environmental trade-offs should not be overlooked. The study findings imply that the environmental sustainability of bio-based products should be evaluated on an individual product basis and that more radical product developments are required to reach climate-neutral targets.

Jan 2024 | VU Law Students Challenge Colgate-Palmolive's Recyclability Claims: Unveiling the Realities of Plastic Recycling and Sustainability | Jan Willem Slijkoord on LinkedIN

In a recent legal victory, Vrije Universiteit van Amsterdam (VU) law students successfully challenged Colgate-Palmolive's (CP) recyclability claims regarding Ajax Lime cleaner bottles before the Dutch advertising authority. The claims of "100% recyclable," "cap and bottle recyclable," and "bottle made from 100% recycled plastic" were deemed "misleading" by the Stichting Reclame Code (SRC) committee. The SRC's decision, supported by the students, exposes the myth of plastic recyclability and holds companies accountable. The students argue that marketing claims portraying plastic as sustainable are irresponsible, asserting that plastic waste is often downcycled into low-quality materials or not recycled at all.

A scrutiny of Ajax bottles reveals their composition mainly as polyethylene terephthalate (PET) with a red high-density polyethylene (HDPE) cap. While technically recyclable, the recycling rates from mixed post-consumer plastic waste are limited to 39-50%, making the claim impractical. The students' assertion that plastics are not sustainable under current recycling circumstances is supported, emphasizing the need for improved recycling practices. This blog post delves into the complexities of plastic recycling, challenges the sustainability of current practices, and advocates for responsible marketing claims backed by verifiable evidence and certifications: https://www.linkedin.com/pulse/longread-ajax-limoen-bottle-ruling-case-plastic-really-slijkoord-rwdre/

Jan 2024 | Voluntary initiatives to end plastic pollution aren't enough: A global treaty is now needed | World Economic Forum

The battle against plastic pollution requires more than voluntary efforts from businesses. Ambitious, coordinated policy measures spanning the entire plastic life cycle are imperative. Despite recent treaty negotiations attempting to narrow the focus, governments must prioritize comprehensive solutions. The World Economic Forum's Annual Meeting serves as a crucial platform for discussions, offering a unique opportunity to address the issue. Urgent steps are needed as current plastic life cycles remain primarily linear, with alarming statistics showing exponential growth in plastic production and waste. Voluntary initiatives, while beneficial, fall short in scale. A legally binding treaty, supported by the Business Coalition for a Global Plastics Treaty, is advocated to establish harmonized regulations and eliminate plastic waste globally: https://www.weforum.org/agenda/2024/01/plastic-pollution-call-for-global-treaty/

Dec 2023 | Recyclate in any product | Plastics & Rubber

The National Circular Plastics Standard (NCPN) is legislation that will take effect in 2027 and requires companies to incorporate a certain percentage of recyclate in their products. The goal is to encourage the use of recyclate to contribute to a circular economy. Implementation of the NCPN involves consultations with various stakeholders, including companies, ministries and industry associations. An administrative trading system that allows companies to negotiate the use of recyclate, similar to carbon emissions trading, is being developed. Sounding board groups and technical working groups are also active to discuss the exact scope, monitoring, enforcement and other aspects of the legislation. The exact requirements regarding the percentage of recyclate in products by 2030 have yet to be determined, but it is expected that resources will be available to help companies transition to using recyclate. However, there are still concerns about the lack of a level playing field and the impact of the standard on the Dutch industry.

Dec 2023 | Unveiling Advances In Chemical Recycling: A Conversation With Professor Kevin Van Geem

In Europe, recycling rates remain relatively low, with only 38% of waste in the EU being recycled(Eurostat, 2022). A rapid scale-up of recycling capacities and infrastructure is critical to meet the EU's mandatory targets. We need to see plastic waste as a valuable resource and a key element of a circular economy. The idea behind circularity is to establish a continuous cycle, including collection, sorting, recycling and regeneration. https://cefic.org/media-corner/newsroom/unveiling-advances-in-chemical-recycling-a-conversation-with-professor-kevin-van-geem/

Oct 2023 | EPR Position Paper | Recycling Network Benelux

The paper discusses the governance issues surrounding Extended Producer Responsibility (EPR) schemes and their impact on the effectiveness of EPR in addressing environmental concerns. It highlights the need for EPR schemes to focus on the entire lifecycle of products, including design, production, and use-phase, rather than solely on end-of-life management. The absence of harmonization across Europe, inadequate cost coverage, and the non-inclusion of stakeholders outside the EU are identified as major obstacles. The concept of free riders benefiting from EPR systems without contributing their share of the costs is also addressed. The document recommends combining EPR with other economic policies and provides legislative measures to advance the working of EPR, making it an effective environmental tool that helps achieve reduction, prevention, and separate collection of waste.

Aug 2022 | Chemical Recycling: State of Play | Eunomia

CHEM Trust publishes a detailed report on "Chemical Recycling," a set of technologies that are often claimed to be on the cusp of revolutionizing the recycling of plastics. This study finds that these technologies in reality have major problems, including substantial energy use, a need for pre-sorted, good quality plastic input and concerns about hazardous chemicals.

The report, "Chemical Recycling: State of Play," written by the environmental consultancy Eunomia, reviews available information on a large number of different chemical recycling technologies, and attempts to assess their performance and feasibility, including their energy use, climate impacts, to what extent they are able to address hazardous chemicals and how they might fit into waste management systems.

April 2022 | Probabilistic material flow analysis and emissions modeling for five commodity plastics as macroplastics and microplastics | Zipeng Liu , Bernd Nowack

This study addresses the critical need for detailed knowledge regarding polymer flows in the anthroposphere and their impact on the environment, essential for effective plastic management. Focusing on five specific polymers-polyurethane (PUR), acrylonitrile butadiene styrene (ABS), polyamide (PA), polycarbonate (PC), and polymethyl methacrylate (PMMA)-probabilistic material flow analysis (PMFA) was employed. The analysis traced polymer flows from production across 45 product categories to end-of-life scenarios in Europe and Switzerland. Results revealed significant variations in polymer flows, influenced by their diverse applications. The study estimated macro- and microplastic emissions into Switzerland's environment for 2018, indicating masses of 208±76 t for PA, 179±98 t for PUR, 79±26 t for PC, 36±23 t for PMMA, and 25±6 t for ABS. These emissions represented a small fraction relative to Switzerland's total production and imports, challenging previous, potentially inflated, estimates and suggesting a more realistic scenario for countries with effective waste treatment systems.

Feb 2022 | Improved science-based transformation pathways for the development of safe and sustainable plastics | Environment International

Projected plastic production volumes are rising, as is societal and political attention to plastic pollution and possible health impacts. In line with ambitions for climate mitigation and the circular economy, various national and international policies and action plans address the reduction of impacts of plastics. Quantitative scenario analyses show that even if current ambitious targets to reduce plastics are achieved, plastics will remain a source of millions of tons of environmental pollution annually. To achieve a sustainable transformation of the global plastics economy, 'extraordinary effort' and 'coordinated global action' beyond current ambitions are needed. While mapping knowledge gaps for the effects of micro and nano plastics (MNP) is crucial, mapping alone is not enough to achieve the needed transition. In this communication, we propose a scope for the exploration of societal transformation pathways to safe and sustainable plastics. To see which efforts are needed globally we need to advance in the following three areas: (i) embedding risk assessment methodologies in wider cost-benefit and life cycle analyses; (ii) using safe-and-sustainable design strategies that include alternative solutions and look at multiple life cycles, and (iii) reflecting on the societal transformation pathways with stakeholders by using co-created quantitative models. We believe that these practices are crucial in the coming decade to realise the extraordinary effort of defining safe and sustainable plastics.
