As we know that the most difficult waste to decompose is plastic waste, because it is to minimize the waste, we must find a solution how to order the community to replace the use of commercial plastics. What is difficult to unravel.
Bioplastic is a plastic from raw materials in the form of Pati in nature.cause Pati is a natural polymer, so it can be in the form of bioplastic, or plastic that quickly decomposes by the soil Its way of making is classified very easy.

MDI
First sago and water mixed in and then heat to a thick gel. After gel occurs, MDI added castor oil and glycerol to a plastic reinforcement material
Then in print in glass casting and dried at room temperature
The picture above is a bioplastic image that has been printed on the glass, shaped sheet ...
And bioplastic can decompose by the ground within 3 months ... so no long decomposition is not like commercial plastics that are now difficult to decompose up to hundreds of years ... if in Indonesia use this plastic ... surely Indonesia is free from garbage
this is my information for you to pay more attention to the plastic waste that is around us ...
