“…For example, the average weight loss for the CUT 1 arch support clips was higher by about 7% in comparison to the CUT 2 arch support clips, which could have been due to the addition of biochar. Similar observations were reported by [ 19 ] who concluded that the addition of 15% (by weight) to PLA/PBA resulted in an extension of the degradation time. Biochar can function as a reinforcement due to its porous structure [ 18 ].…”

“…The novelty of this work is demonstrated by the overall approach to the researching, developing, manufacturing and testing of bio-based and biodegradable alternatives to plant clips produced from fossil-derived and non-biodegradable materials such as polypropylene (PP) or polyvinyl chloride (PVC). Most of the literature references report the results from laboratory studies on biochar-added composites [ 17 , 18 , 19 ]. However, this work reports the selected properties and performance of the manufactured products, i.e., stem and arch support clips, validated and demonstrated in a relevant environment.…”

Increasing quantities of waste from using conventional plastic in agriculture and horticulture is one of the most pressing issues nowadays. Conventional plastic accessories (e.g., mulching films, clips, pots, strings, etc.) are typically fossil-derived, non-biodegradable and difficult to recycle after their use. Therefore, there is a need for biodegradable and bio-based alternatives with similar properties to conventional plastics, which can be disposed of through degradation in water, soil or compost under specific conditions. This work investigated the properties and the performance of biodegradable biochar-added and bio-based stem and arch support clips. In addition, the investigated clips were composted with tomato residues during 16 week laboratory composting. The scope of this work included: (1) the production of stem and arch support clips in a pilot installation using injection molding technology, (2) an analysis of their chemical composition, biodegradability, disintegration and phytotoxicity, (3) an evaluation of their performance in the greenhouse cultivation of tomatoes and (4) an evaluation of the composting of the clips with on-farm organic waste as an end-of-waste management method. The stem support clips during industrial composting (58 °C) degraded at 100% after 20 weeks, whereas during home composting (30 °C) the degradation was slow, and after 48 weeks the maximum weight loss was 5.43%. Disintegration during industrial composting resulted in 100% fragmentation into particles with sizes less than 2 mm. Phytotoxicity tests demonstrated that the substrates after industrial and home composting did not have a negative effect on the growth of the test plants (i.e., mustard, wheat, cuckooflower). The biochar-added stem support clips proved to be satisfactory alternatives to conventional non-biodegradable, fossil-derived clips and can be disposed of through composting. However, more work is needed to determine the optimal conditions for composting to ensure rapid degradation of the clips in relevant environments.

“…The solution-state nuclear magnetic resonance (NMR) is also an extremely useful spectroscopic tool which explores the magnetic properties of certain atomic nuclei ( 1 H and 13 C, mainly). 1 H NMR has also been employed for evaluating the decomposition of PLA, PBAT and PLA/PBAT blends under various conditions: abiotic incubation in hot water [ 29 , 30 , 31 ] or paraffin [ 31 ]; burial in soil [ 32 ]; industrial composting [ 29 ]; and laboratory aerobic [ 33 , 34 ] and anaerobic procedures [ 34 ].…”

“…However, as the order of the polymer chains increased prior to degradation in the order initial PLLA > pressed PLLA > PLLA/RM-β-CD, the increase in orderliness during slower degradation at 50 °C for pressed PLLA/RM-β-CD films was not that significant. This is probably due to the nature of the degradation process, which occurs in a privileged manner in the amorphous regions of the sample, causing faster degradation of this phase [ 38 ]. This is because an increase in orderliness results in a higher diffusion resistance to transport and the ratio of the effective diffusion coefficient (depending on the concentration or upstream pressure) to the diffusion coefficient (expressed as length 2 ·time −1 ) decreases [ 39 ].…”

Poly(L-lactide) is capable of self-assembly into a nematic mesophase under the influence of temperature and mechanical stresses. Therefore, subsequent poly(L-lactide) films were obtained and characterized, showing nematic liquid crystal properties both before and after degradation. Herein, we present that, by introducing β-cyclodextrin into the polymer matrix, it is possible to obtain a chiral nematic mesophase during pressing, regardless of temperature and time. The obtained poly(L-lactide) films exhibiting liquid crystal properties were subjected to degradation tests and the influence of degradation on these properties was determined. Thermotropic phase behavior was investigated using polarized optical microscopy, X-ray diffraction, and differential scanning calorimetry. The degradation process demonstrated an influence on the liquid crystal properties of pressed polymer films. The colored planar texture of the chiral nematic mesophase, which was not observed prior to degradation in films without the addition of β-cyclodextrin, appeared after incubation in water as a result of the entrapment of degradation products in the polymer matrix. These unusual tailor-made properties, obtained in liquid crystals in (bio)degradable polymers using a simple method, demonstrate the potential for advanced photonic applications.
