Follow the development of our t-Project, which stands for radical solutions towards true sustainability without compromise. The interchangeability of discarded parts in our shoes has been an important aspect of our design concept from the very beginning. At t-project we are continuously working on improvements with new materials to create circular design solutions. Over the years, we have consistently collected used and B-quality soles, as well as leather scraps, which now form the basis for our latest developments.
 


 



Revive

knitting and laces made of circular plastic yarn, sole made of 50% recycled old soles, 25% new natural rubber, 25% new synthetic rubber

The synthetic yarn is made of 70 % PET bottles and 30 % ocean plastic. After use the spanish manufacturer is able to recycle the knitted upper into new yarn that retains its original strength. The design of the upper shows the three-dimensional development in visible patterns,
with integrated knit lacing. Incorporating our self-developed recycled rubber sole, “Revive” becomes our next step towards circular footwear.

 

 

 

 

 

 





Proto

upper made of reused prototypes sole made of 50% recycled old soles, 25% new natural rubber, 25% new synthetic rubber

Proto is composed of our experiments: We obtain the leather from deconstructed first prototypes and samples, repeatedly manipu- lated until workable. Elements such as seams, laces, eyelets, zippers or elastics become visible, making each pair of shoes completely unique. Leather defects, white inscriptions or correction details become part of the design.

 

 

Aware / Beware

vegan, plastic-free, 98% biodegradable

This season we have chosen post-consumer jeans as the new material for our t-project models “Aware” and “Beware”.
The selected jeans are 100% cotton and sourced from sorted clothing donations in Berlin. Because of the material’s used & unique nature, the fabric will vary significantly in the shades of blue, brightness and strength. A replaceable footbed made from natural cork is integrated into the inno- vative naturalrubber sole, stabilised through 3 stitched layers, avoiding the need for additional support.



 

 




Our latest sole development goes a step further towards our vision of a circular shoe. For this, we use a rubber compound developed by the University of Chemnitz, which consists of 60% shredded expired soles and 40% new natural rubber. The soles made from this compound can then be recycled again to construct the next batch of soles.




In our bag production, larger leftover pieces of leather accumulate, which we constantly collect. From this we were able to produce small-sized shoe uppers and thus introduce another element of recycling into our production cycle.

Recycled shoes







 
Karma/ Kismet - Upper made from leather scraps, sole made from 85% recycled old soles and 15% PUR.







 





We have added two new styles with a heel strap and Velcro closure to our recycled mules from last summer.
This season we are using the leather scraps from our bag leather here as well. 'Aura' has the square shape of 'Karma' and 'Ambience' the round shape of 'Kismet'.

Biodegradable shoes

 


Natural rubber

• The 1st layer supports the foot
• The 2nd layer provides stabilisation
• The 3rd layer reinforces the sole (easy to repair)

t-project Aware:

Vegan, biodegradable and plastic-free design, designed by the next Trippen generation. Most new materials on the market contain a certain amount of synthetic components and are neither as beautiful nor as robust as leather. While researching already existing functional materials, we came across Belgian mail bags made of sturdy linen from the 60s, which we complemented with an inner lining made of soft cotton. The inner footbed made of natural cork completes the innovative sole, for which we developed a construction made of natural rubber. All the necessary support functions are taken over by the three sewn layers of the sole, therefore making further reinforcing materials such as glue unnecessary.

Only for the yarns do we need the strength of polyester, making the shoes 98% biodegradable.

Aware is a 98% biodegradable pair of sneakers, made out of old Belgian linen mailbags, three layers of natural rubber and undyed cotton shoelaces.



 



Beware
- vegan, plastic-free, 98% biodegradable.

We also continued the development of our plastic-free, vegan and biodegradable sneaker "Aware".
To complement this mid-height sneaker, we have designed a flat model for this season with eyelets that quote the military tent tarpaulins they are made from.
Aware" is also available in this new (old) material.
