bioplastic

Of or relating to bioplasts and bioplasm.

Near-synonym: bioplasmic

The smooth or organic involuntary muscular fibres are single bioplastic elements, long so-called cells, each with a nucleus situated about the middle. They contain microsomata, and in disease deposits of degeneration resembling those of the striated muscle […] The smooth muscular fibres require yet to be studied more closely, which is a matter of some difficulty, as they cannot easily be isolated. ¶ CHEMICAL CONSTITUTION OF THE BLOOD (HEMOPLASM). The blood, like the brain and muscles, must be considered as a great aggregate of bioplastic centres, the corpuscles, and of bioplastic matter, the living serum; as such it is an organ, but unlike other organs, which are fixed, it is in a state of constant movement. Morphologically the walls of the blood-vessels are the limiting membrane of this aggregate hemoplasm, though when fully developed for their ubiquitous function they do not any longer stand in any chemical or histological relation to their contents. The living serum may therefore be considered only in a morphological sense as the enchylema of the blood-vessels considered as stroma. But the corpuscles fully preserve their bioplastic structure, such as we have defined it in the first chapter.

Any form of synthetic polymer, similar to normal plastic, made from renewable biomass sources such as plant sugars, starches, or oils, rather than from petroleum.

A bioplastic can be defined as a polymer that is manufactured into a commercial product from a natural source or renewable resource. A bioplastic can be biodegradable, but a biodegradable plastic does not mean the material was derived fully or in part from a biological source.
