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.
These polymers have the distinct advantage that over time they will break down. Dr. Geoffrey Coates headed research to create catalysts that can not only efficiently create these biodegradable polymers, but the polymers also incorporate the greenhouse gas and global warming contributor, CO 2, and, environmentally present ground-ozone producer ...
Biologically-based polymers, sourced from non-fossil materials, can decompose naturally in the environment, whereas some plastics products made from biodegradable polymers require the assistance of anaerobic digesters or composting units to break down synthetic material during organic recycling processes.
Conversely, biodegradable plastics can also be synthesized from fossil fuels. [4] [12] As of 2018, bioplastics represented approximately 2% of the global plastics output (>380 million tons). [13] In 2022, the commercially most important types of bioplastics were PLA and products based on starch. [14]
An example of a compostable polymer is PLA film under 20μm thick: films which are thicker than that do not qualify as compostable, even though they are "biodegradable". [15] In Europe there is a home composting standard and associated logo that enables consumers to identify and dispose of packaging in their compost heap.
Phonics Song with Two Words from children's channel ChuChu TV is the most viewed video in India and is the 7th most viewed YouTube video in the world. "Why This Kolaveri Di" become the first Indian music video to cross 100 million views. [1] [2] "Swag Se Swagat" became the first Indian music video to cross 500 million views on YouTube. [3] [4 ...

Biodegradable polymers are classified into three groups: medical, ecological, and dual application, while in terms of origin they are divided into two groups: natural and synthetic. [18] The Clean Technology Group is exploiting the use of supercritical carbon dioxide , which under high pressure at room temperature is a solvent that can use ...
