Since we hate single use containers and our goal is to find alternatives to plastic, we set out to create edible plates and cutlery. It seems like people at festivals, beaches and events are not willing to change their habits of throwing away their plates and cups, so what if we can get them to eat it instead? And if they don't want to eat the whole thing, at least the materials that end up in nature are great food for animals or biodegrade. A few facts about the properties of the bowl, before we start: If it is pressed right, our bowl seems to hold water for at least an hour, before it starts to get soft and loses little bits of bran. The material gets super hard with time, so it might be a good idea to make them on the spot. Plus it's also nice, because while making it, it smells delicious! And about food safety: Right now we are using an aluminium mould, and we haven't really looked into food saftey regulations yet, but we will do this, as soon as we are working on a final machine. Here's how we do it so far: – Mix 80% wheat bran with 20% water For our bowl with 12cm diameter, 45mm hight and 1.5mm wall thickness, we need 60g of bran – Heat Mould to 115°C. A lower temperature is also possible, but might result in longer pressing times and a less sealed surface. You can find out more about our heatable mould here – Load and press mixture with 7 metric tons for 2 Minutes. A lot of pressure seems to help seal the mould shut, so that the steam can’t get out of the mould, which leads to a better surface. We are using this press right now, but are planning to develop a stand alone machine with an incorporated press in the future. You will be able to find out about that here – Slowly release pressure, so that steam can get out slowly If you release the pressure too fast, the evaporating water might blow holes into the material and the bowl appears broken or „exploded“ – Open the mould and take out the bowl after a few minutes the bowl is completely hard
