“…From the above studies it is clear that PCL and its modifications are sensitive to microorganisms and decompose in different environments to variable degrees [19][20][21][22][23][24][25]. The aim of this paper was to investigate the progress of degradation of polycaprolactones modified with TPS or CaCO 3 in seawater from the Baltic Sea, with and without microorganisms.…”

This paper is an investigation of the polymer degradation process in two types of seawater (with and without microorganisms) sourced from the Baltic Sea. The chosen polymeric materials were polycaprolactone modified with either thermoplastic starch (PCL/TPS [ 85%) or calcium carbonate (60% PCL/40% CaCO 3 ) compared directly against unmodified polycaprolactone. All samples were incubated for 28 weeks in seawater with and without microorganisms under laboratory conditions and analysed before and after the degradation process. Weight loss analysis, microscopic observations of polymer surfaces and tensile strength tests were used to determine the progress of polymer degradation. The experimental results obtained indicated, that in each of the experiments, degradation of tested polymeric samples occured. The process was more effective in seawater with microorganisms compared against systems without added microorganisms. The experiment in seawater demonstrated that modification of PCL with calcium carbonate did not encourage the degradation process; and in some circumstances inhibited it.

“…The strongest effect of weight loss is observed for poly(ester‐urethane)B, despite of being partially crosslinked. It could be mainly explained by degradation of poly(ε‐caprolactone) in this biotic environment as result of enzymatic hydrolysis of ester bonds susceptible to fungal degradation 19–21. This is opposite to results of degradation in sea water,14 where the conditions were favorable for the development of aerobic epilithic bacteria.…”

The estimation of degradability of different polyurethanes under natural weather depending conditions in compost pile was the subject of this study. The incubation of polymer samples took place for a period up to 24 months. The characteristic parameters of the compost: temperature, pH, moisture content, and activity of dehydrogenases were monitored and their influence on degradation of polyurethanes was discussed. The compostability of polyurethanes was investigated by changes of weight, tensile strength, morphology, and thermal properties. The degradation study revealed that the degree of degradation of polyurethanes in the natural environment, like compost, is dependent on their chemical and structural composition. © 2012 Wiley Periodicals, Inc.

“…According to the available literature, PCL (and its modifications) undergo biodegradation in the presence of specific microorganisms. Its degradation occurs to different extents, depending on different environments [28][29][30][31][32][33][34][35]. La Carra et al [30] examined the degradation of pure PCL as a result of the attack by various microorganisms.…”

In this paper an overview of novel biodegradable polymers for food packaging is presented. The aim was to present factors influencing polymer degradation and biodegradation in various environments. It was noted that biodegradable polymers are an imperfect alternative for classical polymers and their decomposition strongly depends on degradation environment. It was also shown that there are various approaches in different countries to certification of biodegradable polymer materials, which rather complicates its application than promotes it.
