E-CO-FFEECreate the eco - life by reusing coffee ground An-Sheng Huang , Mei-Ling Lu Jan. 22th , 2013 Report of Industrial Design Senior Project
E-CO-FFEEBecause of the structure and physical property,coffee ground has some special effects to be usedbefore it is dumped to be kitchen waste.E-CO-FFEE is a series of modular implementsto help users to reuse coffee ground in a clean and convenient way.Users can build up a micro-circulatory systemto make their lives more natural.

1 2PROBLEM MOTIVATION / PURPOSE Why do we have to recycle Coffee Ground? According to the research, if we just dump coffee ground to the refuse area, it will decomposes andIn Taiwan, there are many coffee shop in the department store or on the street. Recently, the produces methane and greenhouse gas, which are 20 times more than the usual. The organic liquidmarket of coffee extend to the convenient store. In order to seize this business opportunity, the also produces pathogen to cause the pollution of underwater.convenient store bring in the innovative coffee machine. However, it also produces large amountof coffee ground. If we make good use of coffee grounds nutrition and organic matter to fertilize, it can keep the ground fertile and make the plant or crop grow. Besides, coffee beans become 10 times larger thanAccording to the statistic, nearly 30000 kg of coffee ground per month is produced by Taiwan, original after brewing. The holes of coffee ground become big ( just like active carbon), so that it canand nearly 40 kg of coffee ground per day is produced by a Starbucks or City Café of 7-11, adsorb the bad smell and moisture. This characteristic can also make a role of helper in home.which is nearby the MRT station. Theres only few coffee shops (City Café of 7-11) will cooperatewith textile factory to make the textile by coffee ground. Most coffee shops just dump it.

13 14SKETCH IV USERS BEHAVIOR RESEARCH Experiment: Asking for coffee ground at coffee shop / Interview: How the coffee shop deal with coffee ground In the process of asking for coffee ground, we discover that we have to make this request, then the worker open the machine to take out coffee ground. Coffee shop is willing to share coffee ground, but the hint of "You can bring coffee ground home for free" is not clear. Theres large amount of coffee ground is produced everyday. Some private coffee shop will reuse coffee ground to fertilize plants, or put it on the corner and fridge to deodorize and exsiccate. Besides, we know by interviewing the worker of 7-11 City Café that: although few of them will cooperate with textile factory to make the textile by coffee ground, most of them just dump it. How is coffee ground produced / The way of collecting coffee ground at present At backstage, the worker grounds coffee by machine, and puts it in the container which is like a tiny pot on the coffee maker. Then a cup of coffee is made after brewing. The way of collecting coffee ground is to make the container knock on the coffee ground box. The coffee ground box has a special tube on it, so that most of coffee ground can be poured out byIn this stage, we improve the form the products, knocking the container on the tube. Then use the spoon to clean out the rest of coffee ground in theand make them modular. container.We try to make them easier to use and make them logical.
