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.
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". [14] In Europe there is a home composting standard and associated logo that enables consumers to identify and dispose of packaging in their compost heap.
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 ...
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 ...
DOHA (Reuters) -Qatari diplomats spoke with Syria's leading rebel faction, Hayat Tahrir al-Sham, on Monday, an official briefed on the developments told Reuters, as regional states race to open ...
While most plastics are produced from petrochemicals, bioplastics are made substantially from renewable plant materials like cellulose and starch. [27] Due both to the finite limits of fossil fuel reserves and to rising levels of greenhouse gases caused primarily by the burning of those fuels, the development of bioplastics is a growing field.
A convicted murderer who escaped from a Mississippi state prison on Christmas Eve was captured Wednesday, according to a Mississippi Department of Corrections post on Facebook.
FORT PIERCE, Fla. — An "iron curtain" has descended here. Residents near a Cold War-era nuclear bomb shelter are wondering what the property's new owners are doing on the other side of the chain ...
