Disposable tableware appears often in Asian restaurants. The design which allows the piling up of every unit densely makes this tableware convenient to be transported.
However, it causes people to sometimes take two units unconsciously. This negligence wastes much.
1.Producing two different colored units, and piling them up alternately during the process of packaging.
It can help people in recognizing if they take two units at once.
2.Using PLA as the material.
PLA can be decomposed by microbes, we can dispose of the tableware with the leftover food and then microbes in the leftovers will increase the speed of decomposition.
