“…Their management in accordance with the principles of circular economy is a major challenge. Spent brewery yeast is one of the main by-products in the brewery industry (about 2.3 kg/m 3 of beer) (Gokulakrishnan et al 2023 ; Vieira et al 2016 ). Currently, the main direction of their management is their use for feed purposes (Bonato et al 2022 ).…”

“…The content values for elements such as nitrogen (N), carbon (C), phosphorus (P 2 O 5 ), potassium (K 2 O), and trace elements, including copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn), can be the source of fertilizer nutrients. The nutritional value of YW depends largely on the quality and raw material and the conditions of the process (Gokulakrishnan et al 2023 ). The heavy metal content in the waste yeast was at very low levels.…”

This study aims to explore the development of sustainable fertilizers from waste materials of a biogas plant and a brewery. These wastes, rich in organic carbon and nitrogen, were processed with sulfuric(VI) and phosphoric(V) acid mixture, facilitating the production of free amino acids and achieving waste sanitization. This treatment produced by-products, which extended the range of possible applications. The highest concentration of free amino acids (360 mg/l) was achieved through hydrolyzing with a 40% concentration medium over 24 h. In this case, the maximum levels were recorded for beta-alanine (69.3 mg/l), glycine (46.8 mg/l), isoleucine (43.5 mg/l), proline (36.2 mg/l), and valine (31.5 mg/l). The study presents two fertilizer technologies, with and without micronutrients, that satisfy European Parliament Regulation 2019/1009 (Ntot > 2%, Norg > 0.5%, Corg > 3%). Bioavailability of nutrients in the formulations ranged from 60 to 100%. The efficacies of these fertilizers were evaluated in 30-day pot trials with various plant species, with both single application and fertigation tested. Multielement analysis confirmed high nutrient transfer in the soil-plant system, and the inclusion of micronutrients led to biofortification of plant biomass in Cu (48.3 ± 7.2 mg/kg), Mn (249 ± 37 mg/kg), Zn (164 ± 25 mg/kg), and Fe (211 ± 32 mg/kg). These sustainable fertilizers present an alternative to traditional, non-renewable fertilizers and offer promising solutions for precision agriculture and environmentally conscious production.

“…It is used in combination with cakes of vegetable by-products, animal oils, grains, and cereals. However, the high cost of fishmeal has led researchers to look for other protein-rich animal in order to obtain balanced fish feed at low cost [ 12 , 13 ]. Lu and Ku [ 14 ] studied the effects of replacing fish meals with shrimp waste meals in diets fed to juvenile cobia ( Rachycentron canadum ).…”

This study aims to use biosafety to reduce illnesses in packing personnel caused by exposure to antioxidants in fish meals in an industrial plant. The work was carried out in the packing area of Hayduk S. A. in Chincha, Peru. A pre-experimental study was carried out using biosafety as a stimulus. Using the SPSS version 22 program, surveys, pre-tests, and post-tests were carried out, and with the data collected, the standard deviation, normality tests, and the tstudent test were calculated. The following conclusions were drawn: In the pre-test, 100% of the workers had no knowledge of biosafety, did not know how to react in occupational accidents, and did not understand the meaning of the Occupational Medical Evaluation (OME). However, after the training, workers demonstrated a thorough knowledge of the subject and were fully aware of the need to take precautions in case of occupational accidents, among other things. R is -0.872 for the linear correlation. This shows that there is a strong correlation between the observed data of positive changes in worker behavior, commitment, and knowledge about biosafety, resulting in disease mitigation. This is an inverse, moderate, negative correlation. It is advisable to maintain scheduled training on biosafety and occupational health issues.
