Bioplastics can utilize previously unused waste materials (e.g., straw, woodchips, sawdust, and food waste). Life cycle analysis studies show that some bioplastics can be made with a lower carbon footprint than their fossil counterparts, for example when biomass is used as raw material and also for energy production. However, other bioplastics ...
Polysaccharides are linear or branched chains of sugar carbohydrates; examples include starch, cellulose, and alginate. Other examples of biopolymers include natural rubbers (polymers of isoprene), suberin and lignin (complex polyphenolic polymers), cutin and cutan (complex polymers of long-chain fatty acids), melanin, and polyhydroxyalkanoates ...
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] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
A bio-based material is a material intentionally made, either wholly or partially, from substances derived from living (or once-living) organisms, [1] such as plants, animals, enzymes, and microorganisms, including bacteria, fungi and yeast. [2] [3]
Examples of emerging bioproducts or biobased products include biofuels, bioenergy, starch-based and cellulose-based ethanol, bio-based adhesives, biochemicals, bioplastics, etc. [8] [9] Emerging bioproducts are active subjects of research and development, and these efforts have developed significantly since the turn of the 20/21st century, in ...
One of the busiest travel days of the year got off to a rough start due to a "technical issue" that disrupted American Airlines flights across the U.S.
