No. No plastic is biodegradable unless it's made from vegetable oil. Most plastic is made from fossil fuel oil.
The problem with this question is that"strong" is a totally subjective value. Without getting into the science of the issue it would seem clear that even if a biodegradable plastic were "strong" when new, it would become weaker as it 'degrades'. As it is worded, there is no really good answer to this question.
The new "green" plastics that are coming to market are basically three (3) types; Biodegradable, degradable and compostable. Biodegradable plastics have an additive that attracts microbes that consume the plastic. Additives in a biodegradable plastic doesn't change the strength of the polymer (plastic). A degradable plastic also has additives, however, the additives in a degradable plastic cause the plastic to break down into smaller and smaller pieces (degrade). A degradable plastic would not remain as strong as the original plastic once the degrading process has started. The third is known as PLA and is made from the starches of plants such as corn. PLA (polylactate acid) does not stand up well to sunlight or heat and products exposed to sunlight or heat will be affected.
Some plastic is non-biodegradable, in the sense that it takes longer than several lifetimes for the plastic to disintegrate. A glass bottle is essentially non-biodegradable.
because they arnt biodegradable so wont break down.
no because plastic isn't biodegradable.
no there is not because a plastic bag is not biodegradable
plastic
No, but it is recyclable.
they are.
One advantage of biodegradable plastic is that they are renewable. Another advantage is they are known to be better for the environment.
no, plastic can never be considered a biodegradable waste because it cannot be made into simpler substances by the microorganisms
