Biodegradable plastics are commonly used for disposable items, such as packaging, cutlery, and food service containers. [13] In principle, biodegradable plastics could replace many applications for conventional plastics. However, this entails a number of challenges. Many biodegradable plastics are designed to degrade in industrial composting ...
Boxed products made from bioplastics and other biodegradable plastics. Few commercial applications exist for bioplastics. Cost and performance remain problematic. Typical is the example of Italy, where biodegradable plastic bags are compulsory for shoppers since 2011 with the introduction of a specific law. [16]
In typical parlance, the word biodegradable is distinct in meaning from compostable.While biodegradable simply means an object is capable of being decomposed by bacteria or other living organisms, "compostable" in the plastic industry is defined as able to decompose in aerobic environments that are maintained under specific controlled temperature and humidity conditions.
Biodegradable additives can convert the plastic degradation process to one of biodegradation. Instead of being degraded simply by environmental factors, such as sunlight ( photo-oxidation ) or heat ( thermal degradation ), biodegradable additives allow polymers to be degraded by microorganisms and bacteria through direct or indirect attack.

The first known use of biodegradable in a biological context was in 1959 when it was employed to describe the breakdown of material into innocuous components by microorganisms. [57] Now biodegradable is commonly associated with environmentally friendly products that are part of the earth's innate cycles like the carbon cycle and capable of ...
A disposable (also called disposable product) is a product designed for a single use after which it is recycled or is disposed as solid waste. The term is also sometimes used for products that may last several months (e.g. disposable air filters) to distinguish from similar products that last indefinitely (e.g. washable air filters).
