Evaluating the Ready Biodegradability of Biodegradable Plastics
Environmental Toxicology and Chemistry, 2021Abstract Reducing the environmental burden and assessing the safety of plastics are huge global challenges. However, standard test data on the ready biodegradability of plastics are limited. We evaluated the ready biodegradability of 8 biodegradable plastics using Organisation for Economic Co-operation and Development (OECD) test ...

Biodegradability and biodegradation of poly(lactide)
Applied Microbiology and Biotechnology, 2006Poly(lactide) (PLA) has been developed and made commercially available in recent years. One of the major tasks to be taken before the widespread application of PLA is the fundamental understanding of its biodegradation mechanisms. This paper provides a short overview on the biodegradability and biodegradation of PLA.

Biodegradability and Biodegradation of Polyesters
Journal of Polymers and the Environment, 2007A variety of biodegradable plastics have been developed in order to obtain useful materials that do not cause harm to the environment. Among the biodegradable plastics, aliphatic polyesters such as: poly(3-hydroxybutyrate) (PHB), poly(e-caprolactone) (PCL), poly(butylene succinate) (PBS), and poly(l-lactide) (PLA) have become the focus of interest ...

BIODEGRADATION OF TRIETHANOLAMINE
Environmental Toxicology and Chemistry, 1996Abstract Triethanolamine production in the United States exceeds 100,000 metric tons per year. Given this magnitude of production and widespread distribution to consumer product, specialty chemical, and agricultural chemical markets, an understanding of the environmental fate and lifetime of this chemical is warranted.

Current Opinion in Biotechnology, 2001
Widespread studies on the biodegradation of plastics have been carried out in order to overcome the environmental problems associated with synthetic plastic waste. Recent work has included studies of the distribution of synthetic polymer-degrading microorganisms in the environment, the isolation of new microorganisms for biodegradation, the discovery ...

Biodegradation of oxo‐biodegradable polyethylene
Journal of Applied Polymer Science, 2008AbstractBiodegradation of polyethylene and oxo‐biodegradable polyethylene films was studied in this work. Abiotic oxidation, which is the first stage of oxo‐biodegradation, was carried out for a period corresponding to 4 years of thermo‐oxidation at composting temperatures. The oxidation was followed by biodegradation, which was achieved by inoculating

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1974
Abstract The significance of biodegradability in the treatment and discharge of waste waters to natural bodies of water is discussed. Various methods of assessing biodegradability are described and their limitations illustrated by a consideration of the characteristics of bacterial growth and metabolism, including the phenomenon of co-

The biodegradation of hydroquinone
Environmental Toxicology and Chemistry, 1982AbstractHydroquinone is readily degraded by an acclimated activated sludge unit when present at concentrations of 100 mg/L in synthetic photographic or synthetic domestic wastes. A number of pure cultures of yeasts, fungi, and bacteria were isolated from soil and sludges which can utilize hydroquinone as a sole carbon source.1,4-Benzoquinone, 2-hydroxy-
