Environmental degradability of polycaprolactone under natural conditions

Abstract: Abstract. The aim of this work was an estimation of susceptibility of biodegradable poly(-caprolactone) (PCL) to environmental degradation in different natural environments. The commercial poly(-caprolactone) film, the trade name "CAPA 680", was degraded in the compost, pond, open and harbour area of the Baltic Sea. Characteristic parameters of all natural environments were monitored during the incubation of polymer samples and their influence on degradation of PCL was discussed. Susceptibility of PCL to deg… Show more

“…Only a limited number of studies focus on the degradability of biodegradable polymers in water sources and show disputable results as different methods were used for following the degradability . In many studies, samples were placed in a perforated basket in seawater (SW), and weight change of the leftover material is noted making no demarcation between the weight loss due to biodegradation or simply due to the disintegration of the samples to microplastics getting lost in the sea as secondary microplastics . The studies under controlled conditions using standard characterization techniques are required to understand the degradation behavior and to provide a comparative basis.…”

“…Previous studies of other groups reported the investigation of the biodegradability of poly(ε-caprolactone) in several biotic environments, including river and lake waters, sewage sludge, farm soil, paddy soil, creek sediment, roadside sediment, pond sediment, and compost [38,39].…”

“…Similarly, negative effects of unloaded chitosan nanoparticles on plant growth have been already reported, being related to biofilm formation and reduced water uptake . Another important aspect is the degradation of PCL in the environment, which can result from chemical hydrolysis of ester bonds or from microorganisms that secret extracellular enzymes, such as cutinase, lipase and esterase . Kah and colleagues evaluated the fate of atrazine‐loaded PCL nanocapsules in two agricultural soils, demonstrating that the nanoencapsulation did not change the degradation of atrazine .…”

“…50 Another important aspect is the degradation of PCL in the environment, which can result from chemical hydrolysis of ester bonds or from microorganisms that secret extracellular enzymes, such as cutinase, lipase and esterase. 51,52 Kah and colleagues evaluated the fate of atrazine-loaded PCL nanocapsules in two agricultural soils, demonstrating that the nanoencapsulation did not change the degradation of atrazine. 53 This finding could be attributed to the rapid release of atrazine in comparison with the herbicide degradation or to biotic or abiotic degradation of the atrazine associated with the nanocarriers.…”
