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)

Short description
It was of utmost importance for the processing of the entire project to gain knowledge of the composition of the plastic waste that potentially was collected in less developed countries. To this end, data and information (types, qualities, quantities, framework conditions, logistics, etc.) were first collected, analysed and evaluated, including on site in the example countries Sierra Leone and Mauritius.

Short description
In this WP, waste treatment plants were planned in various variants. For this purpose, national and international framework conditions connected with the construction and operation of the ship-based facilities to be developed were determined. Various known procedures were evaluated and tested for their suitability, as were requirements for operation, maintenance and repair. On this basis, the objectives for the treatment of plastic waste were defined, followed by the development of conceptual designs.

Short description
The market for secondary raw materials was examined, since these are fundamentally valuable. Tradeable products from plastic waste were identified and the quality requirements to be met specified. Possible revenues were also estimated. The resulting technical requirements for processing technology and quality management were taken into account in the other WPs. Based on the results, strategies for the most economical processing and marketing of products made from plastic waste were developed.

Short description
The concepts and preliminary planning for the ship-based collection, processing and marketing of plastic waste from less developed countries developed in the project were evaluated under economic and ecological aspects. On the basis of the results, the ecological advantages (reduction of the input of plastics into the environment, protection of resources by recycling plastic waste) were determined. The evaluation of the economic efficiency was intended to assess the chances of realisation and provide a planning framework for potential investors, funding providers and operators of a ship-based collection and treatment plant for plastic waste.

Marker-Based Sorting and Recycling System for Plastic Packaging

The goal of this project was to set up a markerbased system for sorting and recycling that involves every stage from packaging development and sorting technology to high quality material reuse. The MaRek project demonstrated the usefulness of fluorescent markers for waste management applications. For this purpose, the use of the TBS technology developed and patented by the project partner Polysecure was piloted as a possible solution and then tested in an industry-relevant way, especially for the sorting of plastic packaging (LVP). The speed, effectiveness and economic efficiency of sorting different compositions of the collection fractions were investigated under industry-relevant boundary conditions. The project addressed the entire value chain of the packaging life cycle from design to process development for marker application and sorting to recovery of the materials. Approaches to a new packaging governance were elaborated with the relevant stakeholders and, in the medium term, should serve as a basis for more sustainable packaging use in addition to the technical results of the project. In this way, the developed process can make an important contribution to increasing the recycling rate required by the new packaging law.

Main areas of work

Representative recycling of lightweight plastic packaging including determination of the technical residual value (material properties) and the added value potential
New or further development and industrial testing of the "tracer-based sorting" method with real batches from separate collection (pilot plant), for this purpose further development of tracer and detection technology
Applied innovation research for the investigation of drivers and obstacles of the developed technology and their application in the complex structure of stakeholders
Comprehensive analysis of energy and material flows and an assessment of possible environmental impacts of the developed technology taking into account the life cycle perspective

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

Short description
The central experimental elaboration and technological validation of the solvolysis process took place through the operation of the pilot plant. The process engineering solutions found in the basic investigations in WP 1 were implemented here. First, PET of a higher purity was processed. For this purpose, the continuous operation is represented. The final goal was the continuous operation of the pilot plant for mixed PET waste streams.

Short description
The aim was to establish a closed and consistent mass and energy balance of the continuous processing method (for single-variety and mixed PET waste) parallel to the experimental development of the recycling process. This was first created for the continuous operation of the pilot plant, compared with the operating data and then scaled to potential market scenarios. Based on the formulated requirements and the data from the pilot plant, a model-based tool for the analysis and evaluation of environmental impacts was developed.

Short description

By means of potential analysis, the proportion of recyclable technical waste in machine tools and industrial plants in Germany was also estimated. Based on this, new sources of supply for PET waste composites from post-consumer collections and technical applications was developed. New potential partners for the implementation of the newly developed solvolysis process in the value chain and the new disposal channels was identified.
