Recycling and Repurposing of Plastic Waste for Advanced 3D Printing Applications

REPAIR 3D

The Repair 3D project (2019-2022), funded by the European Union's Horizon 2020 programme, aims to develop innovative methods for the recovery and reuse of carbon fibres from carbon fibre-reinforced polymers (CFRPs) as well as the recycling of thermoplastic waste. These compounds will be used in the development of new recyclable CFRPs for high value-added products with advanced functionalities (self-sensing, self-healing and recycling) by combining nanotechnology and additive manufacturing technologies.

Period of implementation

January 2019 – January 2023    
 

Context

The use of plastics has increased twenty-fold in the past half-century, and their linear, take-make-dispose value chains impose significant economic and environmental drawbacks. Pollution, landfills and CO2 emission are major environmental issues, thus the need for development of green technologies, recycling of materials and efficient use of land, are becoming more and more important, with EU adopting directives to promote them.
However, nowadays, the presence of a great variety of complex structures, contaminants derived from an inadequate waste management and limitations in the current recycling technologies make the recovery and recycling of waste very difficult.

 

Summary and objectives    

The Repair3D project aims to address all aspects and stages of the development of carbon fibre  reinforced thermoplastic materials (CFRPs) through additive manufacturing (AM) from recycled resources, starting with the selection of suitable waste streams, material repair strategies, compatibility and upcycling  for different additive manufacturing processing technologies. The circular use (recycling) of materials across multiple manufacturing and recycling cycles will also be demonstrated and optimised, facilitating the creation of new pathways for recycling carbon fibre reinforced composite polymers (CFRPs).  

The strategic goal will be realised through the following specific objectives:

  • Recycling and upcycling of selected thermoplastic waste streams and reclamation of CFs from CFRPs.
  • Development of sustainable CFRPs by additive manufacturing from recycled resources with design-for-recycling, smart-by-design and advanced functionalities.
  • Demonstration of the circular use of the composites developed through separation and reprocessing of AM (advance manufacturing) printed products

Consortium

ITENE´s role in Repair 3D

The Repair 3D project is organized in 9 work packages (WP), and ITENE is mainly involved in the following work-packages and tasks:

WP1: Recycling, repair and upgrade of materials from plastic waste streams:

- Selection of plastic waste and optimization of the shredding process.

- Evaluation and upcycling of each plastic waste fraction to meet the requirements of CFRP matrix materials for additive manufacturing processes.

- Characterization of the different fractions.

WP3: Recycled materials processing with selected AM technologies:

- Evaluation of the mechanical properties of the different materials produced by additive manufacturing.

WP5: Second phase of separation/processing of AM produced parts:

- Demonstration of the circular use of composite materials by the separation, shredding and reprocessing of parts produced by additive manufacturing

 WP6: Life cycle assessment and cost evaluation

- Life cycle analysis of the different processes and products of the project.

- Evaluation of exposure and release of particles, including toxicological tests.

In addition, ITENE will contribute in terms of dissemination and transfer of exploitation knowledge and data and risk management within WP7- Exploitation, dissemination and communication activities and WP8- Project management.
