More than 150 different monomers can be combined within this family to give materials with extremely different properties. PHA is more ductile and less elastic than other plastics, and it is also biodegradable. These plastics are being widely used in the medical industry.
There are two methods to resolve this problem. One is to modify the carbon chain of polyethylene with an additive to improve its degradability and then its biodegradability; the other is to make a film with similar properties to polyethylene from a biodegradable substance such as starch. The latter are however much more expensive.
Disposable plastic cups made from biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all ...

Biodegradable polymers are mostly plant-base materials, which means they originally come from organic source like soybean or corn. These organic plants have the chance to be sprayed with pesticides which contain chemicals which can contaminate the crops and be transferred into the final finished product.
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
The films would be biodegradable and offer better oxygen barriers than synthetic, chemical-based films. More research must be done to improve the water barrier quality of the dairy-based film, but advances in sustainable packaging are actively being pursued. [34] Sustainable packaging policy cannot be individualized by a specific product.
High-performance plastics are thus about 3 to 20 times as expensive as engineering plastics. [2] In the future, a significant price decline cannot be expected, since the investment costs for production equipment, the time-consuming development, and the high distribution costs are going to remain constant.
