“…To our knowledge, only a single study about PA 11/PBS blends was performed, where a composition-dependent improvement of the impact strength of PA 11 was reported, without affecting other mechanical properties, like the flexural modulus [21]. From these results, it appears that the addition of PBS has potential to improve properties of PA 11, also taking into account that PBS is not only bio-based, but also biodegradable and compostable [22,23], contrarily to PA 11. In addition, the production of PBS only requires half the costs as the production of an equivalent amount of PA 11 [24,25,26].…”

“…The biodegradation of PBS chains is initiated by the hydrolysis of ester bonds, which leads to the formation of water-soluble fragments with a molar mass lower than 500 Da. These short PBS chain segments can be assimilated by microorganisms, and then turned to carbon dioxide, water, and biomass [22,23]. Conversely, PA 11 is not easily decomposable in the environment.…”

The manuscript details the preparation and characterization of binary blends of polyamide 11 (PA 11) and poly(butylene succinate) (PBS), with PA 11 as the major component. The blends are fully bio-based, since both components are produced from renewable resources. In addition, PBS is also biodegradable and compostable, contrarily to PA 11. In the analyzed composition range (up to 40 m% PBS), the two polymers are not miscible, and the blends display two separate glass transitions. The PA 11/PBS blends exhibit a droplet-matrix morphology, with uniform dispersion within the matrix, and some interfacial adhesion between the matrix and the dispersed droplets. Infrared spectroscopy indicates the possible interaction between the hydrogens of the amide groups of PA 11 chains and the carbonyl groups of PBS, which provides the compatibilization of the components. The analyzed blends show mechanical properties that are comparable to neat PA 11, with the benefit of reduced material costs attained by addition of biodegradable PBS.

“…Abiotic factors refer to non-living factors (sunlight, water, soil types, pollutants and nutrients, and pH values), while biotic factors mean the involvement of living organisms. Soil burial is a traditional and standard method for the investigation of biodegradation process, occuring in similar conditions to those suffered by wastes disposed on soil [22][23][24][25].…”

Polypropylene–cellulose composites have great potential in many important commercial applications, and it is important to understand and properly evaluate their biodegradative behavior to achieve improved composite formulations in accordance with their future applications. In the present study, an outdoor soil burial test was performed in order to evaluate the susceptibility to degradation of polyolefins–cellulose composites. The structural and morphological changes were analyzed by Fourier transform infra-red spectroscopy with attenuated total reflectance (FTIR-ATR) and scanning electron microscopy (SEM). The weight loss of composite samples after burying in soil was recorded. The presence of new bands, as an indicator of degradation, was confirmed by FTIR-ATR spectra. The thermal stability of the composites after soil burial analyzed by TGA was slightly improved, with relatively higher temperatures being required to decompose the samples after exposure to environmental factors. SEM micrographs presented some modifications of the polymer surface, such as holes, cracks, exfoliations, and fractures. Increasing the cellulose percentage of the composite samples led to increased weight loss. From the obtained results, it can be concluded that composites based on polyolefins and renewable resources undergo a slow process of biodegradation after contact with environmental microorganisms and, with appropriate composition, could be applied to various environmental fields.

“…166 Recent research works have suggested PBS reinforcement to make it more thermostable than PLA. 167–172 PBS is degradable by microbes in different environments, such as soil, sludge, and water, both in aerobic or anaerobic conditions; the degradation is caused mainly by ester bond hydrolysis. 173 PBS is an aliphatic polyester that consists of succinic acid as monomers, which are acquired from renewable or fossil fuels.…”

The methods available for the disposal of synthetic polymers are not advanced in an environment-friendly way. Consequently, their waste persists as a non-degradable pollutant that discharges toxic substances, which have now reached the deepest parts of the ocean. As an alternative, biopolymers such as polylactic acid, polyhydroxyalkanoates, and poly(butylene succinate), synthesized from natural sources such as plants, animals, and microbes, are an eco-friendly option, as they are biodegradable and a better option to shift from synthetic polymer dependency. The fabrication of electrospun nanofibers (NFs) using biopolymers is a novel approach, by which new ideas have been proposed in various fields, such as agriculture, biomedical, food packing, textiles, adsorption, drug delivery, three-dimensional printing, etc. Electrospun NFs are receiving increasing attention due to their diverse properties, including flexibility. This review provides a perception of the novel biopolymers that are currently utilized by the electrospun technique and their various applications.
