Abstract
: Studies on packaging made of polylactide (PLA) subjected to long-term influence of soil environment conditions have been presented in this paper. The scientific objective of this study was to determine changes in selected properties of the PLA packaging after long-term incubation in soil. These changes were investigated by scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and gel permeation chromatography. The structure, thermal properties, and disintegration degree of the packaging after their three-year incubation in soil have been discussed. It was found that the PLA packaging did not disintegrate significantly in the soil environment, and slight changes in their structure and lack of significant changes in thermal properties indicate that
期刊介绍：
Archives of Environmental Protection is the oldest Polish scientific journal of international scope that publishes articles on engineering and environmental protection. The quarterly has been published by the Institute of Environmental Engineering, Polish Academy of Sciences since 1975. The journal has served as a forum for the exchange of views and ideas among scientists. It has become part of scientific life in Poland and abroad. The quarterly publishes the results of research and scientific inquiries by best specialists hereby becoming an important pillar of science. The journal facilitates better understanding of environmental risks to humans and ecosystems and it also shows the methods for their analysis as well as trends in the search of effective solutions to minimize these risks.
