While buying clothes online, most customers are uncertain about the size that would fit them. Hence, 30% of the ordered articles are returned and handling these operations costs up to 50% of a company’s revenue. Half of these returns are reported to be due to size fitting issues and most of the articles are damaged during the process and then burned. Alter Ego provides a tool that will allow shoppers to have a real fitting room experience on their smartphones. Check out the Video: Users will have to download a few body pictures on our application which will create their Avatar: a 3D representation oftheir bodies with precise measurements. Users will then be able to use their “Alter Ego'' on shopping platforms, get sizerecommendations and even try the outfits on their avatars. This process will drastically reduce online returns, retailerswill be willing to pay a license to use the avatars and our system on their platform. ...

Insects play a central role in our ecosystems. They are important for pollinating various plants and form a substantial part of the food chain. Unfortunately, the diversity and quantity of insects has declined sharply in recent years and decades. Where they used to hum loudly, they are now silent. There are many reasons for this, ranging from intensification of agriculture to changes in land use patterns to the increasing threat of climate change. It is imperative to protect insects and their diversity. For this reason, Hier Summts is committed to raising awareness about the diversity of insects, their benefits and insect mortality throughout Switzerland by educating members and the general public about the importance of insects to local ecosystems. General knowledge about insect conservation is to be conveyed in as many ways as possible, such as through school visits, excursions and lectures. So far, we have been able to offer various events on entomology and biodynamic viticulture which are open to both members and non-members.

Labwear Studios is transforming fashion manufacturing to create a more equal, efficient and sustainable production solution. The fashion industry has a major sustainability problem. Clothing is produced in large quantities, shipped to Europe, put on sale and the remaining stock is tried to be sold with big discounts. However, 20-30% of the clothes produced cannot be sold and end up on a landfill. So far, the industry lacks an alternative model that prevents overproduction and eliminates market entry barriers, as currently the minimum quantities are too large for emerging designers to build their own brands with their own products.Team – Labwear Studios Labwear Studios manufactures clothing for fashion designers and brands in the best factories in Portugal starting at as few as 50 pieces. The production takes only 4-6 weeks, instead of the usual 6 months in Asia. The production system of Labwear is based on the idea of "Lean Manufacturing" and applies this system of the car industry to the fashion industry. Labwear optimizes production to the smallest possible quantities to produce more agile, faster, and without overproduction. In addition, the garments are designed for a circular economy.

After finding out that SPH doesn't recycle its waste plastic from the 3D printers, I wanted to do something about that. Recycling these plastics is possible, and with enough care taken to sort them, they can be reused for 3D printing with results comparable to original filament. The extrusion is then carried out with an Artme MK3. Most of the input material is failed 3D prints, design iterations, and support material. That needs to be sorted for a high quality result, removing impurities and other types of plastics. One difficulty for reaching a good quality result is purity: PLA and PETG need to be reliably separated. After shredding into granules, the material is extruded into 1.75+/-0.03mm filament. This is comparable to Prusa's commercial PRUSAMENT at 1.75+/-0.02mm. ...
