Bioplastics called drop-in bioplastics are chemically identical to their fossil-fuel counterparts but made from renewable resources. Examples include bio-PE , bio-PET , bio-propylene , bio-PP , [ 20 ] and biobased nylons.
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]
[2] [3] As an aromatic polyester from ethylene glycol it is a chemical analogue of polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). PEF has been described in (patent) literature since 1951, [ 4 ] but has gained renewed attention since the US department of energy proclaimed its building block, FDCA, as a potential bio-based ...
Ingeo is a range of polylactic acid (PLA) biopolymers owned by NatureWorks. [1] Resinex Group distributes Ingeo in Europe. [2]Ingeo is created using carbon stored in plants via photosynthesis and takes the form of dextrose sugar.
NatureWorks LLC is an international company that manufactures bioplastics—polymers derived entirely from plant resources—as an alternative to conventional plastic, which is made from petroleum. The commercial quality polymer is made from the carbon found in simple plant sugars such as corn starch to create a proprietary polylactic acid ...
In typical parlance, the word biodegradable is distinct in meaning from compostable.While biodegradable simply means an object is capable of being decomposed by bacteria or other living organisms, "compostable" in the plastic industry is defined as able to decompose in aerobic environments that are maintained under specific controlled temperature and humidity conditions.
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.
Some microorganisms can directly consume plastic fragments and use the carbon as a nutritional source. For example, Brevibacillus borstelensis, Rhodococcus rubber, Pseudomonas chlororaphis, and Comamonas acidovorans TB-35 have all been shown experimentally to use direct action to consume polyethylene.
