“…This natural food additive is used e.g. as a preservative, pH regulator, flavor, solvent, and gelling agent ( Ali, Anjum & Zahoor, 2009 ; Ameen & Caruso, 2017 ). Studies have demonstrated that BSG hydrolysate can be used as a substrate for lactic acid production by Lactobacillus delbrueckii, Lactobacillus pentosus, or Lactobacillus rhamnosus NBRC14710 ( Cruz et al., 2007 ; Shindo & Tachibana, 2004 ).…”

Beer is the most popular low-alcohol beverage consumed in large amounts in many countries each year. The brewing industry is an important global business with huge annual revenues. It is profitable and important for the economies of many countries around the world. The brewing process involves several steps, which lead to fermentation of sugars contained in malt and conversion thereof into alcohol and carbon dioxide by yeasts. Beer brewing generates substantial amounts of by-products. The three main brewing industry wastes include brewer’s spent grain, hot trub, and residual brewer’s yeast. Proper management of these wastes may bring economical benefits and help to protect the environment from pollution caused by their excessive accumulation. The disposal of these wastes is cumbersome for the producers, however they are suitable for reuse in the food industry. Given their composition, they can serve as a low-cost and highly nutritional source of feed and food additives. They also have a potential to be a cheap material for extraction of compounds valuable for the food industry and a component of media used in biotechnological processes aimed at production of compounds and enzymes relevant for the food industry.

“…Additionally, they find application in disposable utensils and cups, as fibers in polyester clothing, in packaging, or as filaments for 3d printing [28][29][30]. Glycolic and lactic acids serve as the basic units and raw materials for synthesizing PLA and copolymers of lactide and glycolide, with lactic acid currently obtained from renewable feedstock [31]. Direct polycondensation, azeotropic and solidphase polycondensation, and ring-opening polymerization are the most common methods for synthesizing polyesters based on alpha-hydroxy acid units (Fig.…”

Glycolide and lactide function as the commonly used diester monomers for the preparation of high-molecular weight, degradation-prone (co-)polyesters. Both glycolide and lactide-based polymers are widely used in medicine, pharmaceuticals, the food industry, and additive technologies. This review on the diesters, spanning research from 1833-1854 to the present, encompassing their structural peculiarities, physico-chemical properties, and the range of different methods for obtaining themincluding reaction mechanismsfrom lactic and glycolic acids, their esters, and halogen derivatives. The review also discusses the chemical transformations of lactide and glycolide (apart from ring-opening polymerization) into valuable organic and high-molecular compounds, such as acrylic acid, nitrogen-containing heterocycles, and functional polymers with novel properties.

“…Limitations of chemical synthesis methods include a dependence on a byproduct of another process, their inability to produce the L‐lactic acid monomer exclusively and high manufacturing costs. One of the main sources of cellulose used in the production of PLA is corn starch . Some of the potential applications of PLA are in single use items such as food containers, cold drink cups, blister packaging, cutlery, plates, outdoor novelties, packaging applications, grocery bags, and diapers …”

In this paper, we report the synthesis and characterization of polylactic acid (PLA)‐MAX (Ti3SiC2, Ti3AlC2, and Cr2AlC) and PLA‐MoAlB composites by fused deposition modeling (FDM). Detailed scanning electron microscopy (SEM) studies showed that the particulate phases are uniformly dispersed in the PLA matrix of 3D‐printed samples. Differential scanning calorimetry (DSC) results showed that the addition of MAX phases promoted crystallization of PLA matrix as compared to MoAlB particulates. The mechanical testing results showed that the PLA matrix is sensitive to the addition of MAX or MoAlB phases, for example, PLA‐5 wt% Ti3SiC2, PLA‐5 wt% Ti3AlC2, and PLA‐5 wt% Cr2AlC had a UTS of ~39 MPa, ~30.5 MPa, and ~38.7 MPa as compared to ~41.5 MPa in pure PLA. Comparatively, PLA‐5 wt% MoAlB had a UTS of ~23.2 MPa which shows that predominantly amorphous PLA‐MoAlB composites have lower strength. The tribological behavior improved after the addition of 1 wt% additives, for example, in PLA‐Cr2AlC, the friction coefficient decreased by 76% to ~0.26 from ~0.34 in pure PLA, and the WR marginally decreased in PLA‐1 wt% Cr2AlC to ~2.2 × 10−5 mm3/Nm as compared to 7.7 × 10−5 mm3/Nm in PLA. SEM investigations of the tribosurfaces showed the tribology is governed by the formation of tribofilms. The wettability study showed that all the 3D‐printed samples are hydrophilic in nature.
