“…Prompted by environmental concerns and the limited supply of fossil fuels, many academic and industry-affiliated researchers have focused on investigating natural polymers which are biodegradable. [9][10][11][12][13][14][15][16][17][18][19] This work has identified biodegradable polymers as appropriate materials for the replacement of conventional fossil fuel-based plastics. A biodegradable polymer is defined as a material that can be degraded into carbon dioxide and water through microbial action under normal environmental conditions.…”

Recently, thoughtful disagreements between scientists concerning environmental issues including the use of renewable materials have enhanced universal awareness of the use of biodegradable materials. Polylactic acid (PLA) is one of the most promising biodegradable materials for commercially replacing nondegradable materials such as polyethylene terephthalate and polystyrene. The main advantages of PLA production over the conventional plastic materials is PLA can be produced from renewable resources such as corn or other carbohydrate sources. Besides, PLA provides adequate energy saving by consuming CO2 during production. Thus, we aim to highlight recent research involving the investigation of properties of PLA, its applications and the four types of potential PLA degradation mechanisms. In the first part of the article, a brief discussion of the problems surrounding use of conventional plastic is provided and examples of biodegradable polymers currently used are provided. Next, properties of PLA, and (Poly[L‐lactide]), (Poly[D‐lactide]) (PDLA) and (Poly[DL‐lactide]) and application of PLA in various industries such as in packaging, transportation, agriculture and the biomedical, textile and electronic industry are described. Behaviors of PLA subjected to hydrolytic, photodegradative, microbial and enzymatic degradation mechanisms are discussed in detail in the latter portion of the article.

“…The water uptake and the absorption capacity are the most important properties for polysaccharides, especially for biodegradable polymers. As reported in earlier studies, cells need moist environment to survive and proliferate [59] . One of the major drawbacks of using starch is its water absorption tendency.…”

Starch is an attractive polymer for wound healing applications because of its wide availability, low cost, biocompatibility, biodegradability and wound-healing property. Here, we have fabricated starch-based nanofibrous scaffolds by electrospinning for wound healing applications. The diameter of the optimized nanofibers was determined by field emission scanning electron microscopy (FE-SEM) and was found to be in the range of 110–300 nm. The mechanical strength (0.5–0.8 MPa) of the nanofibrous scaffolds was attuned using polyvinyl alcohol (plasticizer) and glutaraldehyde (crosslinking agent), to impart them with sufficient durability for skin tissue engineering. Absence of negative interactions between the polymers was confirmed by Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR), differential scanning microscopy (DSC) and thermal gravimetric analysis (TGA). Cellular assays with L929 mouse fibroblast cells indicated the ability of the scaffolds to promote cellular proliferation, without exhibiting any toxic effect to the cells. Thus, the nanofibrous scaffolds demonstrated potential for wound healing applications.

Once a biorefinery is ready to operate, the main processed materials need to be completely evaluated in terms of many different factors, including disposal regulations, technological limitations of installation, the market, and other societal considerations. In biorefinery, glycerol is the main by-product, representing around 10% of biodiesel production. In the last few decades, the large-scale production of biodiesel and glycerol has promoted research on a wide range of strategies in an attempt to valorize this by-product, with its transformation into added value chemicals being the strategy that exhibits the most promising route. Among them, C3 compounds obtained from routes such as hydrogenation, oxidation, esterification, etc. represent an alternative to petroleum-based routes for chemicals such as acrolein, propanediols, or carboxylic acids of interest for the polymer industry. Another widely studied and developed strategy includes processes such as reforming or pyrolysis for energy, clean fuels, and materials such as activated carbon. This review covers recent advances in catalysts used in the most promising strategies considering both chemicals and energy or fuel obtention. Due to the large variety in biorefinery industries, several potential emergent valorization routes are briefly summarized.
