“…As the C:N ratio is an important parameter affecting compost microbiology, it is considered as one of the indicator parameters which can be used to detect the degree of maturity, and to classify the quality of the biofertilizer produced. A range from 10 to 15 is recommended as a means of characterizing the end product generated, therefore, the compost gathered from BC 0 and BC 10 met these requirements [13]. However, the high C:N ratio of BC 20 should be due to the high carbon content, which is not actually digestible and, hence, the maturity requested was not reached [53].…”

“…Therefore, food wastes are traditionally proceeded with green waste or bulking agents [12]. The bulking agent (BA) may adjust structural properties, chemical characteristics, composting duration, and leachate formation [13]. It can hold out against the organic acids generated during the early stages of the aerobic digestion, and absorbs part of the leachate produced during the decomposition process in such a way as to ensure a sustainable moisture content and strengthen the microbial activity [14].…”

As bulking agents (BA) affect the composting process, this work examined the impact of combinations of different organic components in order to obtain an efficient co-substrate for food waste (FW) in-vessel composting. To boost the occurrence of microorganisms inhabiting the compost, mature compost was firstly coupled with wheat straw, added to FW, and considered as a control (BC0). Then, two trials (BC10, BC20) including 10% and 20% of biochar were monitored. The results indicated that the temperature of the amended bioreactors was notably increased compared to the unamended one. Thermophilic temperatures were achieved at 14, 34, and 78 h after the experimental setup for BC20, BC10, and BC0, which lasted for 14, 17, and 12 days, respectively. When it came to an assessment of maturity and stability, the quality of the compost was evaluated against several indicators and compared with the compost quality standards of the UK, France, Canada, the USA, Poland, and Germany. BC10 illustrated a high-quality product in relation to the heavy metal concentration, a C:N ratio which reached 14.97, an AT4 which was lower than 6 (4.36 mg O2/g TS), and a nitrification index of 2.61 (<3). Consequently, the addition of 10% of biochar as a co-substrate showed an improvement of the process evolution and the characteristics of the biofertilizer produced.

“…Cellulase activities in composting materials have been widely studied and correlated to decreases in cellulose content [31]. The degradation of recalcitrant lignin in composting systems has been less well characterized, although thermophilic micro fungi, and to a lesser extent actinomycetes, are thought to play key roles [32]. Humification (the process of forming humus) is complex and thought to involve a number of degradative and condensation reactions involving lignins, carbohydrates and nitrogenous compounds [3].…”

Commercial crop production and many other agro-industrial activities generate large amount of cellulose, hemicelluloses and lignin. This research is aimed at the utilization of some of these agro-wastes for the cultivation of Pleurotus ostreatus (Oyster Mushroom) in Keffi area. The agro-wastes (cassava peels (CP), banana leaves (BL), saw dust (SD), yam peels (YP) and groundnut shells (GS) were collected, sorted, shredded, sterilized and inoculated with equal proportions of Pleurotus ostreatus (P. osreatus) for a period of four weeks. Rate of mycelia growth, temperature, mycological identification, nutritional contents of P. osreatus harvested and microbial isolation from the spent mushroom substrates were analyzed. The numbers of days for complete ramification of the substrates by mycelia of P. osreatus were; 18 days for BL and GS, 24 days for CP and YP while 30 days for SD. The room temperature within the period of exposure for fruiting of the ramified substrates ranges between 22°C to 28°C in the morning, 23°C to 30°C in the afternoon and 25°C to 31°C in the evening throughout the period of exposure. The nutritional contents of the Pleurotus ostreatus from the different substrates analysed were, Moisture content was highest in SD (87.05%) and lest in GS (80.71%), Protein content was highest in GS (38.13%) and lowest in BL (16.43%), Lipid content was highest in GS (4.62%) and lest in CP (1.83%), Carbohydrate content was highest in CP (78.40%) and lest in GS (71.66%), Fibre content was highest in BL (9.10%) and lest in YP (8.20%) while Ash content was highest in GS (7.37%) and lest in YP (6.42%). Five bacteria species (Bacillus cereus, Pseudomonas aeruginosa, Micrococcus roseus, Escherichia coli and Bacillus subtilis) and two yeast species (Candida albicans and Candida tropicalis) were isolated from the spent mushroom substrates.

“…El uso de residuos verdes es ampliamente documentado en la literatura (Li et al, 2013). Reyes- Torres et al, (2018) indican que el uso de este residuo puede incrementar el tiempo de proceso debido a la presencia de compuestos lignocelulíticos; no obstante, favorece la formación de sustancias húmicas que incrementan el valor agrícola del producto final. Oviedo et al, (2013 y 2015) evaluaron la incorporación de residuos verdes (i.e Pasto estrella-PE) sobre el compostaje de BOM, encontrando que la proporción de mezcla (17% y 34% de PE) incide directamente sobre el proceso y calidad del producto.…”

La predominancia orgánica de los Biorresiduos (BOM) presentes en los Residuos Sólidos Municipales, favorece su aprovechamiento mediante estrategias como el compostaje; sin embargo, presentan deficiencias que pueden ser mitigadas con la incorporación de materiales acondicionadores. En este estudio se evaluó el efecto de la incorporación de Pasto Estrella (PE) como material de soporte, sobre el compostaje de BOM (proporciones BOM:PE A1 90:10, A2 80:20 y A3 70:30), evidenciándose efectos favorables. A2 mantuvo las mayores temperaturas; A2 y A3 registraron la mayor reducción de sólidos volátiles (SV) y concentración final de nitrógeno total (NT). Los productos finales de A2 y A3 también presentaron mejor calidad en términos de capacidad de intercambio catiónico, contenido de nutrientes (fósforo, potasio y nitrógeno totales), densidad aparente, capacidad de retención de humedad y contenido de materia orgánica, siendo el producto de A2 el de mayor valor agronómico, de acuerdo con la Norma Técnica Colombiana 5167.
