Kaffeeform coffee cups
Coffee cups made from recycled coffee grounds.
What to do with coffee grounds?
The ideal use is to use as compost, add to the garden.
The coffee grounds can be used for growing oyster mushrooms.
In Small Batch they have on sale kits for growing oyster mushrooms. When I saw, I was baffled, but did not inquire.
Small Batch supply their coffee grounds to the Espresso Mushroom Company, a mushroom grower, who in turn, supply Small Batch with mushroom growing kits.
The coffee grounds can be used in cakes, instead of ground coffee.
Rosalie McMillan has created the Java Collection, a range of jewellery that uses recycled silver, gold and diamonds combined with material derived from coffee grounds.
Green Cup turn coffee grounds into furniture.
Kaffeeform turn coffee grounds into coffee cups.
The idea to make cups out of coffee grounds came from studying
Product Design in Bolzano, Italy. After countless cups of espresso,
the founder, Julian Lechner, wondered whether the leftover
coffee grounds couldn’t be used for something new.
After numerous trials and experiments, the first prototype of
an espresso cup made from coffee grounds was developed in 2009.
The cups are unusual as both reusable and recyclable.
One cup and saucer can be made from the grounds of six cups of espresso, plus natural resins, waxes, oils, cellulose, biopolymers and wood fibre.
The cups include biopolymers. The walls of all plant cells are made of biopolymers, long chain molecules with properties allowing them to be plastically formed, and thereby eliminate use of crude oil based plastics.
At the end of their life, Kaffeform can recycle the cups to form the raw material for 3D printing.
The cups are not 3D printed, are moulded, and 3D printing would probably be more suited to prototype development, but does raise the interesting possibility, if the cups were made available as open source hardware could they be 3D printed locally?
A further question, at the end of their life, can the cups be composted?
The coffee grounds are collected daily from cafés and caterers in
the Berlin area.
In addition to cups, they have now also made a takeaway cup.
A useful comparison would be with the HuskeeCup which uses coffee husks.
It would appear to be a better design than the HuskeeCup.
I have not seen let alone handled or used a Kaffeeform cup, therefore difficult to comment further. But certainly stylish. I would be more than happy to try.
