Challenge: no. 5: Wrap me green: Alternative to bubble paper envelopes
Problem: Bubble paper envelopes are made out of both paper and plastic, making it hard to recycle. People often don‘t want to spend time removing plastic from paper in order to recycle it properly. Instead they toss it into general waste. With the current ecological catastrophe of plastic pollution, it is not desirable to keep using plastic bubbles.
Solution: Our proposal is to replace plastic bubbles with myper (mycelium on paper substrate). It can even have similar flexibility as plastic foil. Drops of myper will be deposited to the inner side of the unfolded envelope. After 3 days of growing, drops of myper will grow into envelopes and mimic characteristics of bubble foil. Then the envelope is folded and ready to use.
Impact: Our proposed final product is much more eco-friendly and sustainable, because instead of using virgin plastic, we would use paper waste and mycelium. For growing mycelium and creating myper, we could use waste paper from T-mobile, making the whole process circular. Vision is to deliver the final product to T-mobile by truck and directly load it with waste paper, reducing travel expenses for logistics.
Feasibility: Option A - The bubble wrap is replaced by flexible plates made of mycocomposite. A1 Publicly available licence up to 1000 kg of processed substrate per year. Test batch of 3300 pcs - 9,18 Kč/Houbálka A2 Full licence. Large-scale production anticipated. - 4,88Kč /Houbálka Option B - The bubble wrap is replaced by „drops“ of mycocomposite applied directly to the inside of the unfolded envelope. These droplets adhere to the paper and the envelope is then glued together. - 2,93 Kč/Houbálka
What you built: Idea of replacing bubble foil by layer of mycelium. Process of manufacturing such an envelope. We identified characteristics needed for the mycelium layer. Developed circular economy of T-Mobile waste. Economic analysis of the production and expected price tags.
What you had before: Experience with growing mycelium, prepared semi-flexible desks of grown mycelium to be show and experimented with on the GreenHack.
What comes next: Pilot project with T-Mobile as a proof of concept. Developing a mycelium material based on paper waste from T-Mobile.
