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.

The factsheet is available here for PDF download.

Beschreibung

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.

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

WP 1 Basic research, process and apparatus design

Project partner
Fraunhofer ICT, Reclay Materials GmbH, RITTEC Umwelttechnik GmbH, SCHILLER Apparatebau GmbH, VTU Engineering Deutschland GmbH

Short description
The technical fundamentals for continuous solvolysis of initially pure PET to multilayer and mixed PET were developed. The data served as the basis for the planning, design, construction and commissioning of a modular pilot plant, which enabled investigations of different apparatus.

WP 2 Pilot studies

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.

WP 3 Accounting and multi-criteria rating

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.

WP 4 Market analysis and technology implementation

Project partner
Fraunhofer ICT, TU Braunschweig ICTV, TU Braunschweig IWF, Reclay Materials GmbH, SCHILLER Apparatebau GmbH, VTU Engineering Deutschland GmbH

Short description
The market requirements with regard to recycling routes and required specifications for new streams of recyclable materials was determined. 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.
