Plastic waste has been identified as an urgent ongoing issue for many years. When plastic
waste is incinerated, it emits greenhouse gases (CO2), along with additional noxious chemicals
(HCl). The only alternative is biodegradable polymers, capable of being decomposed by bacteria to
produce eco-friendly materials.
The humidity, heat, and other circumstances influence the biodegradability of plastic. The
perfect plastics decomposition is by aerobic and anaerobic microorganisms, which would result in
CO2, CH4, water, and disposable biomass. The majority of manufactured biodegradable plastic is
transformed into mulch instead of vapours.
Polybutylene adipate co-terephthalate (PBAT) is a synthetic plastic, derived from petroleum
that is biodegradable, according to an aliphatic unit in the polymer backbone. The inclusion of
aromatic components in the polymeric chains also contributes to PBAT’s strong biodegradability.
PBAT is commonly used in plastic packaging, mulch film, and cutlery.
Polyhydroxybutyrate is a bio-based plastic that is obtained as carbon storage by a wide
number of different bacteria colonies. This biopolymer is renewable and biodegradable, so it can
replace synthetic polymers for ecological, packaging, veterinary, and pharmaceutical purposes.
All in all, replacing semi-synthetic plastic with biodegradable plastic will result in a zero-
carbon effect, which is competitively advantageous
