Biodegradability assessments of organic substances and polymers.

The biodegradation of organic substances is a natural yet poorly understood process. Given that biodegradation assessments form an integral part of chemical regulations to assess the persistent of substances this lack of knowledge needs to be addressed. Official references define the biodegradation process as "The biologically mediated degradation or transformation of chemicals usually carried ...

Biodegradability of biofilm extracellular polymeric substances.

This study discovered that biofilm extracellular polymeric substances (EPS) are biodegradable by their own producers and by other microorganisms when they are starved. The study was performed in a comparative fashion to examine the biodegradability of biofilm EPS by the microorganisms from the original biofilm (its own producers) and from activated sludge (other microorganisms). Four distinctiv...

Bio-Based Polymers with Potential for Biodegradability

A variety of renewable starting materials, such as sugars and polysaccharides, vegetable oils, lignin, pine resin derivatives, and proteins, have so far been investigated for the preparation of bio-based polymers. Among the various sources of bio-based feedstock, vegetable oils are one of the most widely used starting materials in the polymer industry due to their easy availability, low toxicit...

Biodegradability Evaluation of Polymers by ISO 14855-2

Biodegradabilities of polymers and their composites in a controlled compost were described. Polycaprolactone (PCL) and poly(lactic acid) (PLA) were employed as biodegradable polymers. Biodegradabilities of PCL and PLA samples in a controlled compost were measured using a Microbial Oxidative Degradation Analyzer (MODA) according to ISO 14855-2. Sample preparation method for biodegradation test a...
