Problems solved by technology

Petroleum based plastic products ordinarily are not biodegradable and cannot be converted into compost.
Products made from resins that are biodegradable frequently cannot withstand elevated temperatures and lose their rigidity.
This is an acute problem in attempting to make rigid products such as eating utensils that can withstand the elevated temperatures encountered during shipping or use under certain conditions.
