Abstract The growing environmental awareness, the search for alternatives to fossil resources, and the goal of achieving a circular economy have all contributed to the increasing valorization of biowaste to produce bio-based polymers and other high-value products. Among the various biowaste materials, lignin has gained significant attention due to its high aromatic carbon content, low cost, and abundance. Lignin is predominantly sourced as a byproduct from the paper industry, available in large quantities from hardwood and softwood, with variations in chemical structure and susceptibility to hydrolysis. This study focuses on softwood lignin obtained through the LignoForce™… More >

Abstract This study aims to enhance the mechanical properties, disintegration, and dissolution rates of cross-linked carrageenan (CRG) capsule shells by shortening the long chains of CRG through a hydrolysis reaction with citric acid (CA). The hydrolysis of CRG was carried out using varying concentrations of CA, resulting in hydrolyzed CRG (HCRG). This was followed by cross-linking with xanthan gum (XG) and the addition of sorbitol (SOR) as a plasticizer. The results indicated that the optimal swelling capacity of HCRG-XG/SOR hard-shell capsules occurred at a CA concentration of 0.5%, achieving a maximum swelling rate of 445.39% after… More >

Abstract Polylactic acid (PLA), a biodegradable polymer, exhibits superior mechanical strength and processability. However, its broader adoption is hindered by inherent brittleness, low hydrophilicity, and sluggish crystallization kinetics. Chitosan (CS), a natural polysaccharide renowned for its biocompatibility and biodegradability, offers potential to address these limitations. While both materials have garnered significant attention in materials science, research on their integration via melt blending and the resulting performance enhancements for food-contact plastics remains understudied. This research comprehensively explores how different levels of CS content, from 0% to 10%, impact the characteristics of chitosan/polylactic acid (CS/PLA) composites. It specifically… More >

Abstract Nowadays, the development of effective bioplastics aims to combine traditional plastics’ functionality with environmentally friendly properties. The most effective and durable modern bioplastics are made from the edible part of crops. This forces bioplastics to compete with food production because the crops that produce bioplastics can also be used for human nutrition. That is why the article’s main focus is on creating bioplastics using renewable, non-food raw materials (cellulose, lignin, etc.).
