A reflection of the Tutzing Symposion 2021 „Polymers for a better life and circular economy“

Titelbild

Beschreibung

The article reflects on the 59th Tutzing Symposion entitled "Polymers for a better life and circular economy" that took place as an online event in October 2021. Based on the presentations at the symposium, the contribution provides an overview of current debates on the circular plastics economy, as well as insights into existing political regulations, present challenges, and possible future developments with regard to this major societal project.

Among other topics, the article addresses the comparability of life cycle assessments, (chemical) recycling, and challenges in developing new business models. It also addresses the material and political limits of the circular economy and criticizes attempts to locate the responsibility for solving the plastic problem mainly in the individual behavior of citizens. Looking at existing regulations and policy initiatives at national, European and international levels, the article states the lack of a holistic, overarching approach. The article concludes with an appeal for more exchange and discussions between industry, politics and authorities as well as civil society in the political decision-making process.

Beschreibung

Most consumers are familiar with PET from the supermarket. In addition to beverage bottles, PET can be found in packaging trays for cheese, salads, fruit, meat or fish. Each foodstuff places its own demands on the plastic packaging. As a result, most plastic packaging is a mixture of different plastics with suitable properties.

While this has a positive effect on the transport possibilities and shelf life of the foodstuffs, these composite materials cannot be recycled or can only be recycled with great difficulty. This is where the 6th factsheet comes in and presents the innovative revolPET® technology. This process, developed in the revolPET joint project, allows selective depolymerization of the PET content and high-quality production of PET. It thereby takes an important place on the way towards a circular economy.

Beschreibung

The German Packaging Act calls for a significant increase in recycling rates for plastics. In order to be able to produce high-quality recyclates, plastic articles must be separated by type. However, there is currently a lack of satisfactory identification options for the many different plastics.

This is where the technology from MaReK comes in. The joint project successfully developed a detection system using fluorescence tracers, which can significantly improve the sorting and recycling of plastic packaging in the sense of a circular economy.

The fourth factsheet presents the technology, its application areas and its relevance in further detail. It is available here as a PDF download.

In this factsheet, joint project KuWert shows how plastic recycling can be profitable. The research team developed a floating recycling platform, mobile and independent of local structures. The system was tested in coastal cities in West Africa, where a lot of plastic ends up in the sea.

Since high-quality plastic recyclate can only be obtained from clean and pre-sorted old plastic, the team worked with a large number of plastic collectors on land and processors on board. This not only created employment, but also prevented over 60,000 tons of plastic per year from ending up in the oceans. At the same time, value chains were established and a contribution made to climate protection.

The contents of the factsheet are based on research results of the joint project KuWert "Ship-based treatment of plastics for the implementation of value chains". It is available here for PDF download.

Beschreibung

The first factsheet of the research focus is dealing with the question of how consumers can save plastic when buying clothes. It is often difficult to know how much plastic is produced along the textile value chain, before a product arrives in the store. Due to this lack of visibility, it is usually not possible for consumers to estimate the actual amount of packaging of a garment and to act accordingly. The factsheet picks up on this issue and explains at which points in the supply chain plastic packaging waste is generated. It also discusses the role of industry and consumers in this context and points out avoidance strategies.

The contents of the factsheet are based on research results of the joint project VerPlaPoS. The factsheet is available here for PDF download.

Reduction of the Input of Plastics via Wastewater into the Aquatic Environment

The REPLAWA project covered questions of water resource protection in connection with wastewater treatment. The project investigated and quantitatively assessed entry points into water bodies through treatment plants, storm water drainage, and combined sewer overflows as well as swales at treatment facilities and in sewage sludge. It tested and rated various practical methods of reducing and eliminating plastic emissions into waterways during wastewater treatment. Based on the results of these investigations and of assessments regarding international regulatory approaches in this field, the project derived strategies for reducing plastic release from wastewater treatment into waterways. Furthermore the sensitization of policymakers as well as plant operators to this problem is also relevant.

The pollutant in focus of this project was microplastic, which poses the greatest challenges to reach the project’s goals.

The results are of immediate environmental and economic use, as they spread technical expertise regarding the choice and integration of technologies suitable for retaining plastic in wastewater treatment. Relevant political and administrative decision makers benefit from the inventory the project inherently provides and from suggested strategy developments of urban water management.

Main areas of work

Further development and testing of suitable sampling, preparation and analysis methods for plastic particles in wastewater and sewage sludge
Inventory and classification of discharges into water bodies via combined sewer overflows, precipitation water, sewage plant effluents and diffuse sources
Inventory and balancing on large-scale wastewater treatment plants
Evaluation and further development of various technical solutions for the separation of plastics during wastewater treatment by means of comparative tests

Ship-Based Treatment of Plastics for the Implementation of Value Chains in Less Developed Countries as well as for the Prevention of Plastic Inputs into the Environment and Especially in Marine Ecosystems

The aim of the project was to develop concepts and preliminary planning for the implementation of an infrastructure for the collection, ship-based treatment, and marketing of plastic waste in order to reduce the input of plastic waste into the environment and marine ecosystems. The project's target regions were primarily less developed countries in the Global South. Using West Africa as an example, strategies for reducing the input of plastics (in this case macroplastics) into the environment were researched, because the input of macroplastics into the environment is particularly high when functioning waste collection and disposal systems are lacking. Stakeholder dialogues were conducted to assess whether a commodity chain based on plastic recyclates is possible on the West African coast. A prototype model ship was developed and used to determine costs.

Main areas of work

Data collection, analysis and evaluation (local conditions in less developed countries)
Preliminary planning of waste treatment plants
Design of a concept for suitable ship and plant technology
Development of strategies for the implementation of value chains in less developed countries
Analysis and evaluation of results (economic, ecological)

Development of a Recycling Technology for PET Waste Plastics from Multilayer Material and Other Waste Composites

As part of the revolPET project, a solvolytic recycling process for waste PET plastics (Polyethylene Terephthalate) from multilayer and other mixed materials was elaborated and experimentally tested. Inactive patents for solvolysis of single-variety PET waste formed the basis for this research: those solvolytic processes were be enhanced into a continuous waste treatment concept that can recycle PET waste. This enabled the recycling of the PET materials present in the mixed waste and the separation of differing amounts of interfering substances, with the latter being redirected to other uses. The recycling process generates the basic components of PET: monoethylene glycol and terephthalic acid. The flexibility of the process enables sorting of waste from very inhomogenous materials sources such as marine and technical PET wastes. The new recycling process was tested and evaluated in a pilot plant. The data from this testing is included into continuous economic and ecological assessments of the procedure and its integration into the value chain.

Main areas of work

Development of the technical basis for continuous solvolysis
Operation of the pilot plant for experimental development and technological validation of the solvolysis process
Development of a mass and energy balances of the continuous processing methods (for pure and mixed PET waste)
Development of a model-based tool for the analysis and assessment of environmental impacts
Determination of market requirements with regard to recycling routes and required specifications for new streams of recyclable materials
Opening up new sources of supply for PET waste composites from post-consumer collections and technical applications

Consumer Behavior Related to Plastic and its Avoidance at the Point of Sale

Consumers buying products made of or wrapped in plastic play a decisive role in plastic consumption in Germany. A complete avoidance of plastic in everyday life, while unlikely to occur in full, would only be possible with extremely high restrictions. Moreover, many consumers are not aware of how much plastic is put into circulation or into the environment by buying a product. The consumer can, however, influence the use of plastics with targeted product selection at the point of sale (PoS) (e.g. the choice of plastic-free products).

Against this background, this project investigated to what extent the consumer can avoid the generation of plastic waste by making a purchase decision at the PoS. Another aspect was to what extent help can be provided for this decision, e.g. through different avoidance strategies. This was examined using food packaging and clothing textiles as examples. The former was chosen because food packaging has the highest capital costs for the environment in absolute terms (UNEP 2014). Textiles were chosen because they are made of plastic, a high proportion of synthetic fibres is used and a lot of plastic is produced by packaging the textiles.

Short description
The respective offer at the PoS was very important for consumers' purchasing decisions. For this reason, the assortment of practical partners in the food and textile commerce as well as the disposal routes of plastic waste produced in shops were being investigated. This provided a business level overview of the respective volume of plastic. The selected shops were examples of different types of food retailing and textile merchandise management.

WP 4 Plastics along the value chain

Contact person
Sven Sängerlaub, Fraunhofer Institute for Process Engineering and Packaging, Giggenhauser Straße 35, 85354 Freising, e-mail: sven.saengerlaub@ivv.fraunhofer.de

Short description
The aim of this work package was to obtain a general overview of the occurrence and use of plastics (especially intermediate packaging) in the supply chains for textiles, with a focus on functional textiles and men’s fashion, and foodstuffs. The aim was to investigate the areas in which the use of plastic is necessary and where it could be reduced or avoided. Thus, there were various possibilities within the value chains to reduce or avoid the use of plastics, e.g. by optimizing the transport packaging systems between the individual stations.

WP 5 Development and provision of alternative packaging options

Contact person

Project partners
Stadt Straubing, University of Stuttgart, Ludwig Stocker Hofpfisterei GmbH

Short description
For the practical testing of alternative packaging and communication with retailers and end customers, suitable materials were being developed, samples produced and appropriate specifications drawn up for incoming and outgoing processes for manufacture and recycling. Various packaging alternatives for the food sector were then manufactured at IVV on a pilot-plant scale for pilot applications or produced by industrial partners. These patterns represented different approaches to avoid or reduce the use of plastics.

WP 6 Avoidance of plastic along the entire textile supply chain

Short description
Within the scope of a business case, innovative strategies were developed for analysing the entire textile supply chain regarding avoidable plastic use, together with practice partners from the textile industry. First the object of investigation was defined and delineated to provide a specification sheet for the analysis of the actual state, for the formulation of the target state under consideration of cost positions, for monetary advantages, and non-monetary aspects, and for functional, and nonfunctional requirements.

WP 7 Innovative recycling strategies for the textile sector

Prof. Dr. Gerhard Schewe, University of Münster, Chair of Business Administration, Universitätsstraße 14–16, 48143 Münster, e-mail: orga@wiwi.uni-muenster.de

Project partners
Stadt Straubing, University of Stuttgart

Short description
For the unavoidable use of plastics in the textile supply chain, sustainable recycling strategies were developed in a business case in cooperation with practice partners from the textile commerce who see plastics as a promising resource for innovative manufacturing and production processes (for the areas of men’s fashion and functional textiles). The focus was on additive manufacturing processes (colloquially: 3D printing) that offer innovative recycling solutions across divisions and industries thus forming a link to the research area of food packaging.

WP 8 Context-specific life cycle analysis of the product examples

Short description
Which global problems were caused by plastics along their supply chain and how severe are these? This question was answered by means of a context-specific analysis with regard to the entire life cycle of possible product solutions (textile, food) or plastics (e.g. food packaging) and the entire range of problems based on the life cycle assessment method and information from the previous work packages. Various practice partners from the textile and food commerce provided support.

WP 9 Testing "new solutions"

Short description
Based on the results obtained, recommendations for action were formulated for the industries examined and then summarised into compact documentation. The recommendations for action were derived in close coordination with all partners and on the basis of the strengths and weaknesses, opportunities and risks of the solutions and strategies jointly identified throughout the course of the project. The aim was to achieve a clear impact assessment for the solutions and strategies developed and thus contribute to a reduction in use of plastics on the consumer side.

Case Studies

Several case studies in the areas of food packaging and textiles were conducted within this project. For example, alternative packaging variants were developed for the following areas: service packaging, bowls/trays and bags for baked goods. These packaging alternatives were tested in the course of the project with regard to "quality", ”consumer acceptance” and for improvement of the "plastic index".

In the field of textiles, innovative strategies for the analysis of the entire textile supply chain to identify avoidable use of plastics were established together with practice partners. In addition, sustainable recycling strategies were developed that consider plastics as a promising resource for innovative manufacturing and production processes (for men's fashion and functional textiles). The focus was on additive manufacturing processes (colloquially: 3D printing) that offer innovative recycling solutions across divisions and industries.
