“…In this scenario, the use of protein-rich waste from the Colombia aquaculture sector is proposed. The simulation flow is set at 2 tons/day for the fish waste generated by the Oncorhynchus mykiss production in Tota Lake in Colombia [46]. The considered fish wastes must have a high protein content to ensure an increase in amino acids yield.…”

The use of chemical fertilizers is essential for agricultural development when soils do not have the nutritional balance required for plants. The continuous use of chemical fertilizers has changed the soil physicochemical and biological properties. Biofertilizer production has been considered as an alternative to reduce chemical fertilizers dependence and the environmental impact. The aim of this study is the evaluation of three technologies for the production of biofertilizers and bioenergy at technical, economic, environmental, and social levels. Ammonium sulfate and digestate-based biofertilizers were obtained via anaerobic digestion; biochar was produced via gasification; and amino acids as plants biostimulants were obtained via protein hydrolysis. Different indicators were calculated for elucidating the sustainability of the processes. Technical, economic, environmental, and social analysis is performed for each of the biorefineries processing stage (complex and stand-alone) without considering the agronomic stage or other value chain links. Scenario 1 presented a positive impact on the economic, environmental, and social aspects since this process has a payback period of 10 years, a carbon footprint of 0.67 kg CO2-eq/kg product, and a potential to generate nine jobs in the Colombian context due to the products portfolio, in contrast with scenario 2 and 3. As conclusion, the integration of biofertilizers and bioenergy in biorefineries have the potential to expand the range of bioproducts and to increase the process sustainability.

Se modeló matemáticamente la generación de residuos sólidos orgánicos de truchas (Oncorhynchus mykiss) para diseñar un sistema de gestión de residuos y evaluar los impactos ambientales. Las variables de estudio fueron el peso, la producción y el rendimiento de canal en empresas pesqueras de Juli y Pomata región Puno. Se empleó la regresión lineal múltiple y los supuestos de linealidad, independencia, homocedasticidad, normalidad y multicolinealidad para validación del modelo, así como la aplicación de las normas ISO 9001:2015 y la matriz de Leopold modificada. Un muestreo probabilístico estratificado fue aplicado en 17 empresas de la comunidad de Chukasuyo Juli y 29 en Faro Pomata. Los modelos fueron: Juli Ŷ = 32315,99 – 1973,66X2 + 0,32X3 – 421,83X5 (R2 = 97,0 %) y Pomata Ŷ = 9560,59 + 4111,66X2 + 0,41X3–207,16X5 (R2 = 97,0 %), y para la gestión de residuos se diseñó un mapa de procesos. Juli y Pomata mostraron interés en elaborar abonos y ensilados 36 % y 17 %, snacks 17 % y 4 %, ácidos grasos 35 % y 10 %, y vitaminas 12 % y 4 %, respectivamente. Los impactos ambientales evaluados fueron litoral lacustre 65 % y 42 %, suelos agrícolas 88 % y 31 %, pastizales 53 % y 48 %, fauna silvestre 50 % y 23 %, y paisaje 65 % y 41 % en las empresas estudiadas. Conclusión, es posible predecir los residuos sólidos orgánicos de truchas para diseñar un sistema de gestión y evaluar los impactos ambientales derivados de la actividad acuícola.

Aim Lacustrine environments are unique locations to study temporal fluctuations derived from natural and artificial sources within a hydrographic basin. The objective of this study was to analyze the diel cycle of physicochemical parameters and their influence on the phytoplankton community structure in open waters, as well as, to evaluate the total phosphorus and nitrogen contents in the vicinity of fish tanks in the lagoon, and to identify the phytoplankton assemblage in the water column in a diel cycle in an open water area during the rainy and dry seasons. Methods The epilimnion and hypolimnion zones of an open water area were assessed over 24 hours, starting at 10:00 on day one and finishing at 10:00 on day two, obtaining a total of 36 samples (9 samples at 3-hour intervals, in two lake zones, in two seasons). Sampling employed a Van Dorn sampling bottle, and the Morphologically Based Functional Groups (MBFG), Shannon-Weaver and Simpson Indices were employed to describe the identified genera. Results Six of the seven parameters monitored registered higher values during the rainy season; only transparency was higher during the dry season. Fifteen genera distributed in nine classes were identified, with richness and diversity being higher in the rainy season. Conclusions The MBFG and sinking properties of group and genera has influenced the vertical migration of phytoplankton. The daily cycle method effectively captured the fluctuations in physicochemical and phytoplankton parameters over a 24-hour period in both seasons in Chacas Lagoon.
