A plastic is considered a bioplastic if it was produced partly or wholly with biologically sourced polymers. A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44]
There are vast examples and applications of biodegradable polymers. Bio-based packaging materials have been introduced as a green alternative in the past decades, among which, edible films have gained more attention due to their environmentally-friendly characteristics, vast variety and availability, non-toxicity, and low cost.
Typical is the example of Italy, where biodegradable plastic bags are compulsory for shoppers since 2011 with the introduction of a specific law. [16] Beyond structural materials, electroactive bioplastics are being developed that promise to carry electric current .
If disposed of in a sanitary landfill, most traditional plastics do not readily decompose. The conditions of a sealed landfill additionally deter degradation of biodegradable polymers. Polyethylene is a polymer consisting of long chains of the monomer ethylene (IUPAC name ethene). The recommended scientific name polyethene is systematically ...

That plastic, researchers wrote, gets into the soil from plastic packaging, clothing—especially made from acrylic and polyester—and the wastewater from washing clothes, microbeads in personal ...
PHA fits into the green economy as a means to create plastics from non-fossil fuel sources. Furthermore, active research is being carried out for the biotransformation " upcycling " of plastic waste (e.g., polyethylene terephthalate and polyurethane ) into PHA using Pseudomonas putida bacteria.
