Vermicomposting of cow manure: Effect of time on earthworm biomass and chemical, physical, and biological properties of vermicompost

Towards a circular economy in virgin olive oil production: Valorization of the olive mill waste (OMW) “alpeorujo” through polyphenol recovery with natural deep eutectic solvents (NADESs) and vermicomposting

“…All measurements were made manually, washing and drying each individual before weighing, and returning them to the corresponding substrate. The data recorded was used to determine the maximum biomass (MB: g per vermireactor), the maximum growth rate (MGR: mg earthworm −1 day −1 ) and the maximum reproduction rate (MRR: cocoon earthworm −1 day −1 ) for each treatment, as performed previously (Suthar et al, 2012;Ferraz Ramos et al, 2022).…”

“…Vermicompost quality is related to its nutrient content and the nutrient balance in accordance with the regulations in force in Spain (BOE, 2017). The suitability of vermicompost is also related to the time needed to reach its humification and the stability of the final vermicompost, which is more suitable when shorter times are needed to achieve stability (Ferraz Ramos et al, 2022). Significantly, (alpeoNADES + MAN) v was the substrate that required less time for biotransformation of all the substrates tested.…”

“…Durante el proceso de compostaje, bajo la acción de diversos microorganismos y factores ambientales, los residuos orgánicos se descomponen en CO 2 , agua, iones minerales y materia orgánica estabilizada, rica en substancias húmicas (Ferraz-Ramos et al 2022, Hu et al 2021. En el compostaje la producción de CO 2 se encuentra directamente correlacionada con la respiración microbiana aerobia y, por lo tanto, la actividad biológica de los grupos microbianos aerobios directamente involucrados en la descomposición o degradación de la materia orgánica (Kalamdhad et al 2008).…”
