Note 1: Bioplastic is generally used as the opposite of polymer derived from fossil resources. Note 2: Bioplastic is misleading because it suggests that any polymer derived from the biomass is environmentally friendly. Note 3: The use of the term "bioplastic" is discouraged. Use the expression "biobased polymer".
There is also much debate about the total carbon, fossil fuel and water usage in manufacturing biodegradable bioplastics from natural materials and whether they are a negative impact to human food supply. To make 1 kg (2.2 lb) of polylactic acid, the most common commercially available compostable plastic, 2.65 kg (5.8 lb) of corn is required. [57]
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 proposed ban on single-use plastics is a boon for the bioplastic industry, ... Compostability may help solve plastic pollution, but if compostable plastics are still made with fossil fuels, it ...
Whether a material is biodegradable is determined by its chemical structure, not the origin of the material from which it is made. [14] Indeed, the sustainability benefits of drop-in biobased plastics occur at the beginning of the material life cycle, but still, when manufactured, their structure is identical to their fossil-based counterparts ...
Polybutylene succinate (PBS) (sometimes written polytetramethylene succinate) is a thermoplastic polymer resin of the polyester family. PBS is a biodegradable aliphatic polyester with properties that are comparable to polypropylene.
PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid.PBAT is produced by many different manufacturers and may be known by the brand names ecoflex, Wango, Ecoworld, Eastar Bio, and Origo-Bi.
MarinaTex is a bioplastic material designed to serve as an alternative to single-use plastic in a variety of applications. [1] It is translucent and stronger than LDPE plastic. [2] This biodegradable bioplastic is made from red algae and organic waste from the fishing industry. MarinaTex plastic takes between four and six weeks to decompose in ...
