VTT EcoVillage Exhibition

​What if there were no microplastics coming loose from clothes and shoes we wear? Would they still be comfortable stylish, durable, and affordable for everyone? This module displays innovations in the field of textile recycling, all-wood based material solutions for footwear, as well as 3D printing from nanocellulose.

Do you ever wonder what happens to a milk carton lying alongside the road or waste textiles that end up in the nature?

It is important to note that non-biodegradable plastics these products may contain can be harmful for the nature, because they gradually disintegrate into smaller pieces, microplastics, which can end up in marine or freshwater environment. 

VTT has conducted an experiment for this exhibition to study degradation of commonly used packaging materials and textiles. The experiment was performed in composting facility where conditions were optimal for degradation. Four to five weeks of our composting experiment equals several months or even years of exposure to Finnish nature environment, such as being thrown into the forest. A number of textile samples, a shoe and several packaging solutions were studied for their biodegradability.

Below are the outcomes of the biodegradation experiments on textiles (1) and packaging materials (2).

1. BIODEGRADING OF TEXTILES 

During the experiment cellulose-based viscose degraded completely and cotton almost completely in five weeks; at the same time cellulose acetate and synthetic materials like polyester and nylon did not degrade during the experiment. Cellulose carbamate manufactured by VTT’s newly developed technology degraded partly in studied time.

2. BIODEGRADING OF PACKAGING

The results of the experiment showed that uncoated cardboard degraded completely already in four weeks. If packaging material contained polyethylene or aluminum, these components remained undegraded after five weeks of composting.
