The SPARTA project comes to an end developing a new successful recycling solution for aeronautics

The SPARTA project comes to an end with the development of a new recycling solution for aeronautics that allows up to 80% of thermoplastic materials to be reused.

This innovative solution allows to advance towards sustainable recycling by obtaining new high-quality thermoplastic composite products, manufactured with recycled materials, in which up to 80% of the waste is used compared to other recycling methods, and with a production cost between 15% and 20% lower than that of current mechanical recycling and scrap reprocessing processes, thanks to the reduction in the number of operations and the automation of manufacturing processes.

The mechanical properties of the secondary materials that are obtained through conventional mechanical recycling methods, such as grinding, electrodynamic fragmentation, laser cutting or machining, are poor. In addition, these recycling processes require intensive energy consumption. With this novel method, significant results have been achieved compared to the mechanical properties of the virgin compound with an estimated mechanical loss of less than 10%.

In addition, the methodology developed by AIMPLAS and TEKNIKER allows processing time to be reduced by up to 50%, thanks to the reduction of steps for waste recovery and reprocessing through more efficient automatic methods, as well as reducing CO2 emissions by up to 30%, thanks to the use of waste and reduction in the demand for production of virgin material.

It is important to avoid current landfill and incineration practices of composite materials to encourage the development of a cost-effective recycling method and therefore extend the lifetime of materials by promoting the circular economy. The results of this project are fully aligned with the ambitious challenges to achieve clean aviation through eco-design and the optimization of processes and resources, thus promoting the competitiveness and sustainable economic growth of the aeronautical industry. Furthermore, the project results of the environmental and economic impact analysis using the 'cradle-to-gate' approach will allow updating the database of the eco-design Transversal Activity (TA) proposed in CS2.

SPARTA arouses the interest of international media

Project SPARTA arouses the interest of international media. JEC Composites Magazine published the scientific article "A new generation of recycled composite materials for sustainable mobility" from Rocío Ruíz, Sustainable Mobility Researcher at AIMPLAS, leading AIMPLA`s activities within the SPARTA project.

In the article, Mrs. Ruíz states composite materials play a key role in the development of lightweight structures that help reduce vehicle weight. The main advantage of using more lightweight materials is the reduction in CO2 emissions. However, there are some drawbacks to using these materials, such as the large volume of waste generated during component manufacture, as well as during the incineration or landfill processes of the materials in the end-of-life stage (EoL).

AIMPLAS starts research to develop more efficient methods of recycling composite materials

The aerospace industry is increasing its use of composite materials because of the advantages they offer in terms of weight reduction and strength. One of the drawbacks of these composite materials is the complexity of recycling them.

In response to this challenge, AIMPLAS is coordinating the SPARTA project, with the participation of TEKNIKER. Both centres will develop a new recycling method for key waste processing and reprocessing procedures. Specifically, TEKNIKER will contribute its knowledge and experience in mechanical cutting to the development and optimization of an innovative mechanical scrapping process, through simulation and experimentation, while AIMPLAS focuses on improving material reprocessing through automatic deposition and compression moulding. This method will make it possible to use up to 80% of current aerospace waste compared to other mechanical recycling methods, cut processing times as much as 50% by reducing the number of steps in waste recovery, use more efficient automatic reprocessing methods, reduce CO2 emissions up to 30% through the use of waste, and curb production demand for virgin material.

The result will be new, high-quality composite thermoplastic products manufactured with recycled materials at a production cost 15 to 20% lower than current mechanical recycling and scrap reprocessing procedures due to a reduction in the number of operations and automation of manufacturing processes. AIMPLAS will also be in charge of analysing the properties of the final product, as well as preparing a guide with eco-design recommendations for industrial scale-up of the process.

The project began this month and will end in October 2022. It has received funding from the EU Research and Innovation programme Horizon 2020 within the framework of the Clean Sky Joint Technology Initiative under grant agreement number 887073. This project is in line with SDG 12 on responsible consumption and production, SDG 13 on climate action, and SDG 9 on industry, innovation and infrastructure.

The AIMPLAS (project coordinator) and TEKNIKER research centres are carrying out this project in collaboration with Topic Manager Royal Netherlands Aerospace Centre (NLR). The SPARTA Project is framed within the Airframe ITD of the CS2 Programme. Its results will contribute to Europe’s strategic environmental and societal priorities while promoting the competitiveness and sustainable economic growth of the aeronautics industry.



AIMPLAS, the Plastics Technology Centre, has a twofold mission: to provide added value to companies so they can create wealth and meet societal challenges to improve people’s quality of life and ensure environmental sustainability.

The institute also supports the 17 SDGs of the UN Global Compact when carrying out work and corporate social responsibility activities.

AIMPLAS is a non-profit research association and member of REDIT (Network of Technological Institutes of the Valencia Region) offering enterprises in the plastics industry comprehensive and customized solutions, including development and innovation projects, training, competitive and strategic intelligence, and technological services such as analysis, testing and technical assistance.
