In this study, the effects of lignin modification on the properties of kenaf core fiber reinforced poly(butylene succinate) biocomposites were examined. A weight percent gain (WPG) value of 30.21% was recorded after the lignin were modified with maleic anhydride. Lower mechanical properties were observed for lignin composites because of incompatible bonding between the hydrophobic matrix and the hydrophilic lignin. Modified lignin (ML) was found to have a better interfacial bonding, since maleic anhydrides remove most of the hydrophilic hydrogen bonding (this was proven by a Fourier-transform infrared (FTIR) spectrometer—a reduction of broadband near 3400 cm−1, corresponding to the –OH stretching vibration of hydroxyl groups for the ML samples). On the other hand, ML was found to have a slightly lower glass transition temperature, Tg, since reactions with maleic anhydride destroy most of the intra- and inter-molecular hydrogen bonds, resulting in a softer structure at elevated temperatures. The addition of kraft lignin was found to increase the thermal stability of the PBS polymer composites, while modified kraft lignin showed higher thermal stability than pure kraft lignin and possessed delayed onset thermal degradation temperature.

“…The uses of organic wastes as fillers can on one side increase some properties and/or reduce the overall cost of the material thus providing cost-effective items. One of the most used green polymers present on the market, together with polybutylene succinate [8][9][10], is the polylactide (PLA) [11]. Green polymers find their most promising application in packaging.…”

Particulate composites with polylactide (PLA) as a matrix and wastes deriving from the wine production have been formulated at different compositions. The microstructure and the mechanical properties of the composites, as well as the thermal stability and water uptake have been evaluated. The results showed that the wine waste residue does not compromise the thermal stability of the matrix while improves the impact strength and influences tensile properties. Specifically, tensile strength progressively decreases on addition of the winery waste, while the elastic modulus slightly increases. This behavior was attributed to the inhomogeneity of the filler particle size and morphology, which can partially induce a discontinuous interface at high filler loading and affect the water uptake. An increase in the value of the water contact angle is obtained below a 10% wt content and the mechanism of water uptake is not modified below the 20 wt% of filler. In any case, up to a content of 15 weight percent, winery wastes can be used in the plain matrix as an extender. Since simple and low cost operations are requested to obtain suitable fillers, an overall decrease in the material cost can be envisaged thus partially solving the drawbacks of PLA exploitation in the packaging industry, and leading to cost‐effective application. Moreover, the conversion of lignocellulosic wastes as filler in biocomposites would be in favor of waste reduction while adding value to the agro‐food chain. POLYM.

Controlled‐release fertilizer is one of the most critical tools in agribusiness for decreasing environmental impacts. Thus, the development of bio‐based systems able to induce the slow release of fertilizers has become the focus of numerous researchers. In this sense, this work presents a slow‐release fertilizer prepared by melt mixing of poly(butylene succinate) filled with 30 wt % urea and 5 wt % montmorillonite clay. The obtained materials were characterized using FTIR, XRD, and SAXS. Also, the release of urea was investigated using gravimetric and spectrophotometric tests. Finally, a vegetable growth analysis was performed to evaluate the development of lettuce (Lactuca sativa L.). The best composite material can increase the diameter of the lettuce by 67%, whereas the conventional use of urea increased this diameter by 48%. Therefore, the presented materials are useful as fertilizer systems.
