Analisis Sifat Mekanik dan Permukaan pada Degradasi Plastik Konvensional
Summary
An Indonesian study tested the degradation of biodegradable plastic materials under UV light, sunlight, and soil burial, measuring changes in mechanical properties and surface structure. The research contributes to understanding how biodegradable plastics perform in real-world environmental conditions compared to conventional plastics.
Currently, plastic waste that decomposes for a long time can damage the environment and natural ecosystems. therefore, an innovation was made to create an environmentally friendly plastic that decomposes faster in nature. The purpose of this research is to determine the degradation ability of environmentally friendly conventional biodegradable plastics. This research uses environmentally friendly conventional plastic materials. This plastic is degraded in 3 (three) ways, namely photodegradation (irradiation with UV C light), irradiation with sunlight, and biodegradation. Each degradation process lasts for 30 days. The research results showed that there was a decrease in the elongation at break value of plastic that had been degraded. This is caused by the breaking of bonds in the polymer chain. Apart from that, the plastic also experiences damage to its surface. This damage is characterized by cracks, the appearance of stains, and the appearance of mold or microorganisms on the plastic surface.

Biodegradable plastics in the air and soil environment: Low degradation rate and high microplastics formation
Researchers compared the degradation rates of various biodegradable plastic types in natural air and soil environments over time, finding that most degraded slowly under ambient conditions and generated substantial microplastic fragments, with non-certified biodegradable plastics showing essentially no degradation.
In-soil degradation of polymer materials waste – A survey of different approaches in relation with environmental impact
This review surveys the in-soil degradation of polymer materials — including natural fibers, synthetic plastics, and composites — examining how environmental factors such as UV radiation, microorganisms, moisture, and temperature drive degradation and influence the environmental impact of plastic waste in terrestrial ecosystems.
Degradation of Biodegradable Microplastics under Artificially Controlled Aging Conditions with UV Radiation
Researchers subjected biodegradable plastics to controlled UV aging and found that they fragmented into microplastics faster than conventional plastics under simulated outdoor conditions. Biodegradable plastics are promoted as an eco-friendly alternative, but this study shows they may actually create microplastic pollution more rapidly in real-world environments. The findings raise important questions about whether biodegradable plastics are a genuine solution to plastic pollution.
After the sun: a nanoscale comparison of the surface chemical composition of UV and soil weathered plastics
Researchers used nanoscale surface analysis to compare how UV light and soil burial weather the chemical composition of plastics differently, finding that each exposure type produces distinct surface changes. These differences affect how plastics interact with surrounding environments, including how they may adsorb or release contaminants as microplastics in nature.
Investigating aquatic biodegradation and changes in the properties of pristine and UV-irradiated microplastics from conventional and biodegradable agricultural plastics
Researchers compared the biodegradation of conventional and biodegradable agricultural plastic mulching films in aquatic environments, testing both pristine and UV-weathered samples. The study found that while biodegradable plastics break down well under controlled composting conditions, their degradation in non-target environments like water bodies is considerably less predictable.
