Fibres from textile waste to be turned into new attractive consumer products

Trash textiles are a valuable resource that should not be left untapped. Aalto and VTT are participating in an EU project called Trash-2-Cash.

Aalto University and  VTT Technical Research Centre of Finland are participating in an EU project called Trash-2-Cash, which pools together designers, researchers, materials suppliers and textile producers from all over Europe.

More than three million tonnes of textiles are thrown away in the EU every year. This is a growing problem, which the EU’s Trash-2-Cash project aims to solve by recycling, and developing high-performance fibres. The Trash-2-Cash project team, which includes experts from all levels of the production chain, is looking for techniques that can be used to spin, knit, sew or design innovative high-quality products from used textile fibres.

The joint project of Aalto University and VTT in the Trash-2-Cash programme aims at developing ecological and efficient techniques. The project involves developing techniques for pre-processing and washing waste textiles, separating fibres, and fiberisation.

The role of VTT is to focus on breaking down the fibres in waste textiles and making them suitable for the cellulose carbamate process. The Ioncell cellulose fibre manufacturing process will be carried out at the Aalto University. The Ioncell-F process has proved to be especially suitable for the recycling of cellulose waste. It is a very robust and stable process which allows the manufacture of textile fibres of the highest quality even from low quality wastes. Further, it allows also to separate the cellulose fraction from blends with polyester while preserving the macromolecular structure of polyester for further use.

Designers involved

Designers play an important role in the project to ensure the quality, performance and appearance of the new products appeal to consumers. The aim is to find new markets and uses for recycled textile fibres. Demo products will be manufactured together with commercial partners throughout the project.

The Trash-2-Cash project is part of the EU’s Horizon 2020 programme, and it will run from 2015 until 2018. The total budget is EUR 8.9 million, of which EU funding accounts for EUR 7.9 million. The project team includes 18 organisations from 10 EU countries. The project is coordinated by SP Technical Research Institute of Sweden. In addition to Aalto University and VTT, Finnish participants include the children’s clothing manufacturer Reima.

Aalto University’s and VTT’s Trash-2-Cash project in brief:

-    VTT pre-processes and washes waste textiles and studies techniques to separate cotton and polyester
-    Aalto University fiberises cotton using Ioncell technology
-    VTT fiberises cotton using carbamate technology
-    Project timescale: June 2015 – December 2018
-    Timescale: started in June 2015 and ends in December 2018
-    The project won the H&M Foundation Global Change Award in February 2016

New ultrasonic needle yields samples 2–3 times larger, potentially reshaping cancer diagnostics

Developed at Aalto University over several years, a new ultrasonic needle for tumour diagnostics has been trialled in collaboration with Helsinki University Hospital (HUS). According to the resulting peer-reviewed study, salivary gland tumours could be diagnosed with far greater precision using the innovative needle.
