“…These compounds mentioned above present in BSG are considered strong antioxidants and may enhance the stability of polymeric materials [61][62][63]. Considering the antioxidant activity of BSG, it may contain noticeable amounts of melanoidins, mainly when it originated from the production of darker beers.…”

Beer is the most popular alcoholic beverage in the world, and its popularity is continuously growing. Currently, global beer production is estimated at around 2 billion hectoliters. Nevertheless, the increasing production capacity implicates the rising issue of generated by-products—brewers’ spent grain, spent hops, spent yeast, and wastewater. They are generated in massive amounts, so having in mind the current pro-ecological trends, it is crucial to look for their utilization methods. Among the possibilities, particular attention should be drawn to polymer technology. This sector can efficiently use different lignocellulosic materials, which could be applied as fillers for polymer composites or sources of particular chemical compounds. Moreover, due to their chemical composition, brewing industry by-products may be used as functional fillers and additives. They could be introduced to enhance the materials’ resistance to oxidation, microbes, or fungi. These issues should be considered especially important in the case of biodegradable polymers, whose popularity is growing over the last years. This paper summarizes the literature reports related to the composition and potential applications of the brewing industry by-products in polymer technology. Moreover, potential directions of research based on the possibilities offered by the brewing industry by-products are presented.

“…The recommended temperatures to print provided by the manufacturer are in a shorter range: 115-145 • C. However, due to the technical restrictions of our 3D Printer, the minimum printing temperature was 172 • C. It provided us with an appropriate polymer fluency during the printing, but the need of an extra fan to obtain a proper cooling down rate. Although it is a high value, we work inside the theoretical safe range of the polymer, decreasing the chance of PCL oxidation, as it has been reported in the literature that the oxidation onset temperature for pure PCL is 240.5 • C [30].…”

Additive manufacturing (AM) techniques are becoming the approaches of choice for the construction of scaffolds in tissue engineering. However, the development of 3D printing in this field brings unique challenges, which must be accounted for in the design of experiments. The common printing process parameters must be considered as important factors in the design and quality of final 3D-printed products. In this work, we study the influence of some parameters in the design and fabrication of PCL scaffolds, such as the number and orientation of layers, but also others of “hidden” importance, such as the cooling down rate while printing, or the position of the starting point in each layer. These factors can have an important impact oin the final porosity and mechanical performance of the scaffolds. A pure polycaprolactone filament was used. Three different configurations were selected for the design of the internal structure of the scaffolds: a solid one with alternate layers (solid) (0°, 90°), a porous one with 30% infill and alternate layers (ALT) (0°, 90°) and a non-alternated configuration consisting in printing three piled layers before changing the orientation (n-ALT) (0°, 0°, 0°, 90°, 90°, 90°). The nozzle temperature was set to 172 °C for printing and the build plate to 40 °C. Strand diameters of 361 ± 26 µm for room temperature cooling down and of 290 ± 30 µm for forced cooling down, were obtained. A compression elastic modulus of 2.12 ± 0.31 MPa for n-ALT and 8.58 ± 0.14 MPa for ALT scaffolds were obtained. The cooling down rate has been observed as an important parameter for the final characteristics of the scaffold.

“…This by-product of coffee is also rich in minerals, especially potassium, calcium and magnesium. In addition, it contains polyphenols such as chlorogenic acid, which is considered a soluble polyphenol derived from the esterification of caffeic acid with quinic acid (Hoseini et al, 2021), with antioxidant properties (Moraczewski et al, 2018), which when ingested by animals can reduce the damage of reactive oxygen species [di oxygen ( ), hydroxyl (OH), peroxide (ROO), alkoxy (RO) and nitric oxide (NO)] (Chaves-Ulate and Esquivel-Rodríguez, 2019).…”

Objective: To review the literature related to the use of husk and pulp of coffee in the feeding of ruminant andnon-ruminant animals.Approximation: The husk and pulp of coffee are by-products that remain after cleaning the bean. These area potential source of pollution; however, they can also be used for animal feed, reducing costs for the producer.Study limitations/implications: Coffee by-products have been used in animal feed globally, especially inthose countries that are the highest producers of this bean. Therefore, it is important to know the resultsobtained there when those by-products are supplied as fed to animals in different conditions.Conclusions: The results obtained vary when these coffee by-products are included in animal diets, dependingon the species and the amount offered.
