“…Natural reinforced composites are used widely replacing synthetic reinforced polymers, especially for industrial application such as the automotive, construction, and packaging industries [3,4]. Investigations have also been carried out to produce composites from natural fiber using different types of matrices, such as polypropylene [5], polyethylene [6], epoxy [7], and polyhydroxybutyrate [8], which is capable of satisfying many engineering applications in terms of energy, strength, and absorption. PLA is a synthetic aliphatic polyester produced from renewable agriculture products such as sugarcane, sugar beet maize, and cassava.…”

Recently, natural fibers have become attractive materials to engineers, scientists, and researchers as an alternative reinforcement for biocomposites. In this study, polylactic acid/abutilon natural straw biocomposites with various abutilon straw weight fractions were prepared by melt blending. The differential scanning calorimetric (DSC) results showed a significant influence of the abutilon straw on the melting behavior of PLA, even at the low abutilon straw contents. The dynamic mechanical analysis demonstrated that the storage modulus, as well as tan delta of the biocomposites, increased when the abutilon straw content increases, which indicates better interaction between abutilon natural straw and PLA. The incorporation of abutilon straw into biocomposites provided favorable changes in rheology related to the matrix. SEM observation revealed good dispersion of the abutilon straw in PLA.

Biodegradable polymers have been developed rapidly in the last years and are widely used today in the fields of pharmacy, clinical biomedicine, cosmetic, medical, packing industries, tissue engineering, agriculture and other areas. The interest in biodegradable polymers has been increasing, mainly due to rising oil prices, which is the basic feedstock of plastic derived from petroleum, and also due to the problem of the removal of waste plastics that accumulate in the environment. Biodegradable polymers have many advantages in contrast to synthetic polymers and can be decomposed in the environment to non-hazardous substances. Biodegradable polymers are classified into two classes based on their synthesis i.e., synthetic and natural polymers. They are derived either from petroleum resources or from biological resources. The following review presents an overview of the different biodegradable polymers and their properties, current scientific research, applications, global production of bioplastic and replacement of conventional plastic.

“…Nowadays, research efforts are centred in developing composites by combining natural fillers with biodegradable resins [ 10 ]. Thus, some researches on poly(lactic acid) (PLA) [ 11 , 12 , 13 , 14 , 15 , 16 ], polyhydroxybutyrate (PHB) [ 17 , 18 , 19 , 20 ], starch-based polymer (TPS) [ 21 , 22 , 23 , 24 , 25 ], polybutylene succinate (PBS) [ 26 , 27 , 28 , 29 , 30 ] or polycaprolactone (PCL) [ 31 ] with different natural fillers/fibres have been reported. In general, it was observed that tensile and flexural modulus increased, but the impact strength and elongation at break decreased.…”

This article is focused on the development of a series of biodegradable and eco-friendly biocomposites based on starch polymer (Mater-Bi DI01A) filled with 30 wt % almond shell (AS) of different varieties (Desmayo Rojo, Largueta, Marcona, Mollar, and a commercial mixture of varieties) to study the influence of almond variety in the properties of injected biodegradable parts. The different AS varieties are analysed by means of Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD). The biocomposites are prepared in a twin-screw extruder and characterized in terms of their mechanical (tensile, flexural, Charpy impact, and hardness tests) and thermal properties (differential scanning calorimetry (DSC) and TGA). Despite observing differences in the chemical composition of the individual varieties with respect to the commercial mixture, the results obtained from the mechanical characterisation of the biocomposites do not present significant differences between the diverse varieties used. From these results, it was concluded that the most recommended option is to work with the commercial mixture of almond shell varieties, as it is easier and cheaper to acquire.
