Drink cups that can be used as fertilizer over the service life

Jointly developed by the University of Michigan and the Greater London City Government. It is made from cereals and used as a bottled beverage to protect against water and oil in a short period of time. When it exceeds the service life, it can be biodegraded and become an excellent fertilizer for gardens. When used as a fertilizer, it is only necessary to chop with a home lawn mower and mix it with the soil to become compost for planting flowers.
