The aim of the study was to characterize and compare films made cellulose nanocrystals (CNC), nano-fibrils (CNF), bacterial nanocellulose (BNC) in combination with chitosan alginate terms applicability for potential food packaging applications. In total, 25 different formulations were evaluated, seven biopolymer best mechanical performance (tensile strength, strain)—alginate, 5% CNC, chitosan, 3% BNC without glycerol, CNF glycerol—were selected investigated regarding morphology (SEM),...
Conventional polymer-based packaging material (polyethylene, polypropylene) has several harmful effects on the ecological aspect as well human beings. Thus an eco-friendly alternative to reduce/solve problem is desirable. Bacterial cellulose (BC) purest form of available from microbes. A wide range application BC reported, health care, mainly due its biodegradability and biocompatibility. In present paper, emphasis been given characterize compare physicomechanical properties BC-based...
Chromium-tanned leathers used in the manufacture of footwear and leather goods pose an environmental problem because they contain harmful chemicals are very difficult to recycle. A solution this can be composite materials from tree leaves, fruit residues other fibrous agricultural products, which replace chromium-tanned leather. The present study describes preparation biocomposite leather-like microbial cellulose maple leave fibers as bio-fillers. formulation was optimized by design...
In this research, eco-friendly PLA filaments were 3D-printed using FDM. Three geometric shapes with different orders of rotational symmetry selected to create infill patterns: an equilateral triangle, a square, and regular hexagon. Additionally, each these three patterns was modified by rotating the basic shape used form pattern 0°, 15°, 30°. The objective study analyze how order within affects mechanical properties printed specimens. To ensure consistency, density kept as uniform possible...
Modifications of the packaging paper surface play an important role in a variety industries, especially food sector. Uncoated has poor water and oil barrier properties due to its porous structure. In this study, was successfully coated with six different coating solutions containing combinations chitosan, zein rosemary essential oil. The chitosan were actually two layers; mixed chitosan–rosemary zein–rosemary each applied as one layer paper. results showed increased papers reduced...
The aim of this study was to develop bio-based adhesives that can be used for various packaging papers. In addition commercial paper samples, papers produced from harmful plant species in Europe, such as Japanese Knotweed and Canadian Goldenrod, were used. research, methods developed produce adhesive solutions combinations tannic acid, chitosan, shellac. results showed the viscosity strength best with added acid tensile chitosan 30% better than 23% shellac chitosan. For most durable pure...
This study identifies the optimal combination of active and passive thermoplastic materials for producing multi-material programmable 3D structures. These structures can undergo shape changes with varying radii curvature over time when exposed to hot water. The research focuses on examining thermal, thermomechanical, mechanical properties (PLA) (PRO-PLA, ABS, TPU) materials. It also includes experimental determination radius programmed pairing PLA PRO-PLA was found be most effective creating...
Polylactic acid (PLA) is one of the most suitable materials for 3D printing. Blending with nanoparticles improves some its properties, broadening application possibilities. The article presents a study composite PLA matrix filaments added unmodified and lignin/polymerised lignin surface-modified nanofibrillated cellulose (NFC). influence untreated NFC on morphological, mechanical, technological, infrared spectroscopic, dynamic mechanical properties was evaluated different groups samples. As...
Mathematical modelling plays an important role in food engineering having various mathematical models tailored for different topics. However, are followed by limited information on their application companies. This paper aims to discuss the extent and conditions surrounding usage of context European drinks industry. It investigates knowledge, nature current use approaches relation industry main characteristics. A total 203 companies from 12 countries were included this research. Results...
The fashion industry generates packaging waste through the entire supply chain. Although brands are making efforts to improve sustainability as demands for low-impact rising, there is a lack of empirical evidence innovative solutions among retailers. This study represents first global report on sustainable innovation in sector. A data-mining approach was utilized gather sample 400 international that advertise across five continents. solution evaluated each brand based three factors: mission,...
Invasive plant species can impede the establishment and growth of native plants affect several ecosystem properties. These properties include soil cover, nutrient cycling, fire regimes, hydrology. Controlling invasive is therefore a necessary, but usually expensive, step in restoring an ecosystem. The sustainability materials with emphasis on use local resources plays important role circular economy. alternative fibers from promotes production smaller paper mills that offer protection...
The aging of paper depends on various factors, including environmental conditions, microbiological factors and chemical composition. Chitosan-coated is an eco-friendly material that has potential use in packaging applications due to its mechanical, barrier antibacterial properties. In this study, the stability chitosan-coated wood-free wrapping was evaluated by examining pulp four samples with different quantities chitosan. Accelerated thermal dynamic thermogravimetric analysis were used...
The great potential of regenerated cellulose fibers, which offer excellent possibilities as a matrix for the design bioactive materials, was lead our research. We focused on surface modification fibers to improve sorption properties and biocomposite cellulose/chitosan are market. purpose investigation also with functionalization by chitosan means obtaining similar Argon gas plasma used fiber activation adsorption. Ultrasound treatment procedure chitosan. Analyses have shown that ultrasonic...
The aim of the study was to isolate lignin from organosolv, beech tree (Fagus sylvatica), and Japanese knotweed (Reynoutria japonica), use it for paper surface replace part non-renewable product resources with bio-based ones. A total nine coated samples different formulations starch were compounded, prepared, evaluated. basic (grammage, thickness, specific density), mechanical (elongation at break, tensile, burst tear indices), barrier properties (contact angle, water penetration, vapour...
