Beach Cleaning Event

   At a beach cleaning event, we found that there was a lot of rubbish on the beach, mostly plastic straws and paper cups. The staff of the event organizer told us that this plastic-containing garbage will break down into plastic microbeads, eventually leaving plastic microbeads on the beach and in the ocean, causing ecological damage. We were very curious about the source of this drifting garbage, so we designed a questionnaire, focusing on recycling containers.

Public Engagement

  We found that people in Taiwan are not clear about the difference between paper containers and other types of recycling. We pursued this issue in two directions: one is how we can solve the problem of the paper cup material, and the other is Taiwan’s larger recycling issue.

Initiating the Project

  In the direction of solving the problem of the paper cup, we first divided the final destination of the paper cup into two categories—recycling and incineration. If a cup is not clearly marked as recyclable, it will cause misunderstanding in the general public, but the latter will increase the harm to the environment, which is not the most appropriate solution. As the result, we thought about creating a new material ourselves. In addition to being decomposable in the environment, this new material also has all the characteristics needed for current paper cup production industries.

  We finally created LIGGREEN, a brand new lining material. However, we encountered many problems during the process. First of all, in terms of design, we abandoned the original idea of using this new material to replace the entire paper cup, because this would affect too many things that we cannot control, which will involve more problems. As the result, we turned to creating a lining material for the inner layer of the paper cup.

Improving the Project

  In designing the paper cup lining material, we asked a lot of paper manufactures and material experts and gain extensive help

Bobsen Paper Ware Corporation

  Since we want to make the lining material of the paper cup, it was necessary to know the current processing conditions of the paper cup laminating industries. Bobsen Paper Ware Corporation gave us the opportunity to visit their factory. We integrated three main criteria that we have to achieve, so that our material could be suitable for the paper factories to enter the lining material market easier. The following three criteria are:

1. Similar melt flow index with PE: The melt flow index of PE is 310 Celsius/12.5 kilograms in 10 minutes. Therefore, our material LIGGREEN needs to have similar melt flow index when in 300 Celsius.
2. Our material needs to end up in round pellets. First, small pellets are easier to transport, pour and suitable for factories, on the other hand, compare with powders it won’t scatter. Then, round shape could make the procedure more fluent.
3. After the entire paper cup procedure completed, an SGS test is required to prove the safety of the paper cup.
