The use of bio-loads in the field of composites has become an essential concern for researchers, as opposed to mineral and classical loads that have dangerous effects on the environment. In this work, a tensile test on a virgin material of animal origin was carried out numerically by the finite element method which was able to confirm the experimental tests. The curves from this simulation mainly considered virgin material in a direction parallel to the fiber direction. The results of the numerical modeling have clearly illustrated that the virgin material has a significant Young modulus in the direction parallel to the fiber, which reinforces the assumptions of the anisotropy of the material of animal origin studied and the high rigidity at the direction of the fibers thanks to the keratin that confers this behavior. This bio load has been mixed with polypropylene for different percentages in order to promote the evolution of its thermo mechanical properties. Numerical modeling by the finite elements characterized the studied bio-composite which can find applications in the fields of the automotive, computers, construction and household articles etc.

“…One of them refers to co-production, which is costefficient and meets the sustainable context of the circular economy. Some examples include the simultaneous production of antioxidant compounds and proteolytic enzymes (Lemes et al, 2016a); lignocellulolytic enzymes and phenolic compounds (Leite et al, 2019); xylanases and xylooligomers (Menezes et al, 2017;Pereira et al, 2018); proteolytic enzymes and protein hydrolysates (Bernardo et al, 2019); lipids and carotenoids (Kot et al, 2019;Costa et al, 2020;Silva et al, 2020); and antioxidant peptides and pigments (Bertolini et al, 2021), among others.…”

Bioactive compounds can provide health benefits beyond the nutritional value and are originally present or added to food matrices. However, because they are part of the food matrices, most bioactive compounds remain in agroindustrial by-products. Agro-industrial by-products are generated in large quantities throughout the food production chain and can—when not properly treated—affect the environment, the profit, and the proper and nutritional distribution of food to people. Thus, it is important to adopt processes that increase the use of these agroindustrial by-products, including biological approaches, which can enhance the extraction and obtention of bioactive compounds, which enables their application in food and pharmaceutical industries. Biological processes have several advantages compared to nonbiological processes, including the provision of extracts with high quality and bioactivity, as well as extracts that present low toxicity and environmental impact. Among biological approaches, extraction from enzymes and fermentation stand out as tools for obtaining bioactive compounds from various agro-industrial wastes. In this sense, this article provides an overview of the main bioactive components found in agroindustrial by-products and the biological strategies for their extraction. We also provide information to enhance the use of these bioactive compounds, especially for the food and pharmaceutical industries.

“…All kinds of microbe may be used in the microbe-enzyme synergism of oil-cake feedstuff to enhance flavour, reduce anti-nutritional factors and improve digestibility (Shi et al, 2016;Odinot et al, 2017;Ohara et al, 2018); however, the most of the collaborative enzymes are proteases which are used to decompose macromolecular proteins in oil-cake feedstuff and improve digestibility or increase the content of specific functional peptides (Wang et al, 2017;Su et al, 2018;Cheng et al, 2019). This is essentially the same process that occurs in the treatment of animal by-products (Bernardo et al, 2019).…”
