Bioplastics are made by convert- ing the sugar present in plants into plas- tic. In the united States, that sugar comes from corn. Other countries use sugar cane, sugar beets, wheat, or potatoes. This makes bioplastics renew- able and better for the environ- ment than conventional plastics.
Bioplastic is a biodegradable material that come from renewable sources and can be used to reduce the problem of plastic waste that is suffocating the planet and polluting the environment.
Yes, bio-based plastics can be recycled. Bio-based plastics such as “BioPE” or “BioPET” are chemically identical to their fossil based versions “PE” and “PET”. That's why they are called drop-ins. Therefore they can be perfectly integrated in established recycling streams.
Instead, PLA-based bioplastics should be taken to a commercial composting facility where it can be broken down in a controlled environment by microbes. Biodegradable plastics, on the other hand, refer to petroleum-based plastics that are combined with an additive that makes them break down quickly.

Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist.
In physics and materials science, plasticity, also known as plastic deformation, is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces.
The region in which the material deforms permanently is called the plastic region. Yield Point: The point demarcating the elastic from the plastic region is called the yield point. The stress at yield point is called the yield stress.
Elasticity is the property of a solid material that allows it to restore its shape after an external load is removed. Plasticity is the property of a solid substance that allows it to keep its deformed shape even when the external load is removed.
The stress is the pressure per unit area of the material, and the resulting strain is the deformation that occurs as a result of this stress. Strain and stress are strongly intertwined because strain occurs solely as a result of stress.
