Special Issue Information

Dear Colleagues,

Low price, easy workability and low mass are some of the reasons for the application of plastic materials in various fields. The inadequate disposal of plastic waste leads to global pollution, and thus, endangers habitats around the world. One way to solve some of these problems is the use of bio-based and biodegradable polymers. Biodegradable polymers are polymers that break down under the action of microorganisms, most often bacteria. In biodegradable polymers, non-degradable components can be replaced by cellulose, starch or other biodegradable compounds. In recent years, bio-based materials have experienced strong growth in the industry, due to recent trends in the consumer market towards greener packaging and waste reduction. Bioplastics, which are both natural and chemically derived materials from renewable or petroleum-based resources, are designed to have a minimal carbon footprint, high recyclability and full biodegradability/compostability. With many innovative bioplastics entering the market for diversified applications, industries are interested in expanding their production capacity. Acute relevance to sustainability and the circular economy is indeed influencing the bioplastics industry to achieve substantial growth and technological maturity with multiple production routes.

This paper investigates the biodegradation properties of cellulose fibers and PLA biopolymer. For that purpose, hemp, jute, and sisal fibers as lignocellulose fibers; viscose fibers (CV) as regenerated cellulose; and polylactide (PLA) as biopolymer were buried in farmland soil for periods of 2, 4, 7, 9 and 11 days under controlled conditions. The influence of their biodegradation on the fiber mechanical properties, bacteria and fungi population, as well as on the soil quality were investigated. After exposure to microorganisms, analyses of the fibers’ morphological (SEM), chemical (FTIR), and thermal (TGA) properties were conducted to achieve a comprehensive understanding of their biodegradability. The analysis concluded that lignin and pectin content have a greater impact on the biodegradation of hemp, jute, and sisal fibers than factors like crystallinity and degree of polymerization. The viscose fibers showed lower biodegradability despite their lower degree of polymerization, indicating a resistance to biodegradation due to the “skin” formed during the spinning process. PLA fibers experienced chemical hydrolysis and significant microbial attack, resulting in reduced tenacity. The acquired findings yield valuable insights into the biodegradability of the fibers, thereby facilitating the selection of appropriate fibers for the development of environmentally sustainable products. Notably, a literature review revealed a paucity of research on fiber biodegradability, underscoring the significance of the present study’s contributions. Full article
