with partial or full
biochemical origin, which may be partially or completely made from natural
materials, are renewable (biomass) and may be biodegradable, meeting
ASTM standards,

Bioplastics are defined as materials containing biopolymers in variable
amounts. They can be shaped by heating and pressure. They are a potential
