“…In the temperature range between 130°C and 180°C, all samples underwent a dehydration process and the most tightly bound water molecule was released. Some volatile components were also released from lateral chains, together with other low molecular weight compounds (Baffi et al 2007). The high volatile matter content inside OPEFB made it easy to burn.…”

“…Hence, the final matured products exhibited small reduction in weight lost due to the existence of stable structure formation (Omar et al 2011). Samples' weight losses in the range between 180 to 410°C and 400 to 600°C were reported to be associated with both the first exothermic peak, which may refer to the cellulosic component, and a second exothermic peak, which may correspond to lignin having more complex organic molecules (Baffi et al 2007). Figure 8(a) shows the residual weight ratio at different stages in the composting process.…”

“…However, up to this point, there has been no reported study on composting OPEFB and POME anaerobic sludge using an in-vessel composting system for field scale operation. Since the composting processes involve changes of chemical composition, several techniques have been used to determine the stability of compost such as X-ray diffraction (XRD), Fourier transform infrared (FTIR) and thermogravimetric, and different thermal analysis (TG/DTA) Baffi et al 2007). Therefore, this study was conducted to evaluate the changes in the lignocellulosic structure of OPEFB during composting by using an in-vessel composting system on a semi-commercial scale.…”

Changes in the lignocellulosic structure of oil palm empty fruit bunches (OPEFB) during composting treatment using an in-vessel composter was investigated in this work. The composting process was completed within 40 days of treatment, and the final C/N ratio achieved was 13.85. Scanning electron microscopy (SEM) revealed that the structure of OPEFB material was severely degraded, especially during the thermophilic phase where the biodegradation process was most active. Close examination of the physicochemical and thermal analysis using X-ray diffraction (XRD), Fourier transform infrared (FTIR), and thermogravimetric and differential thermal analysis (TG/DTA) showed that the crystallinity size of the OPEFB structure decreased. This result was attributed to the removal of silica bodies from OPEFB materials. Also, the functional groups of cellulose, hemicelluloses, and lignin structures had changed throughout the composting period, and the most extensive degradation of cellulose was detected in the thermophilic phase. It was also found that the exothermic peak of the matured compost reduced most significantly compared to the raw OPEFB. In conclusion, the in-vessel composting system was able to enhance the degradation process of OPEFB materials for producing compost.

“…This phenomenon has led to thermophilic microorganisms taking over the declining mesophilic community. Baffi et al (2006) reported that lignin, being a complex and stable materials, can be degraded in the thermophilic phase. On the other hand, new mesophilic community is formed to substitute thermophilic community in the maturation phase.…”

“…Moreover, huge amounts of organic residues produced by agricultural activities have become environmental pollutants since they increase salinity levels, nitrate lixiviation rate into underground and drain water as well as phosphate concentration in surface water (Flotats and Sole, 2008). In addition, organic residues are associated with accumulation of lignin, aromatic oils and resins (Obied et al, 2005), and several pests, weeds and diseases have been disseminated (Baff i et al, 2007) and cases of toxicity in cultivated plants have increased (Zucconi et al, 1981). As a result, the use of organic residues has become increasingly important as an eff icient way to recycle nutrients and stimulate plant growth as well as to incorporate nutrients to degraded soils (Cerrato et al, 2007).…”

El uso de desechos de ganado y residuos vegetales, como fuente de nutrientes y material orgánico para el suelo, puede representar una alternativa viable para evitar daños riesgosos para el agroecosistema, derivados del uso de fertilizantes químicos. El presente estudio fue conducido en 2013, en condiciones de invernadero en la FACIATEC-UACH, Chihuahua, México. Se evaluó la contribución al suelo de los macronutrientes NO3-, P=, K+, Ca++, Mg++ y Na+, a partir de cuatro compostas elaboradas de (a) estiércol de bovinos, (b) excremento de gallina, (c) aserrín y (d) esquilmo de maíz, los cuales fueron comparados con urea como fertilizante sintético y un control sin fertilizante. Se utilizó un diseño completamente aleatorizado y se realizó el análisis de varianza mediante el paquete estadístico SAS (Statistical Analysis System), versión 9.3.1; la comparación múltiple de medias se realizó mediante el procedimiento de Tukey (α = 0.05). Los resultados sugieren que cinco de los tratamientos de compostas incrementaron la concentración de NO3-, en los cuales el estiércol de gallina superó signif icativamente al de bovinos en su aportación de los macronutrientes NO3- y P=; del mismo modo, las compostas elaboradas a partir de aserrín tuvieron un efecto signif icativo sobre el NO3- y superaron a los que contenían esquilmos de maíz. La concentración de Ca++ y Mg++ en los suelos donde se aplicó la composta, fue menor en comparación con aquellos tratados con urea, aunque el contenido de Na+ en los tratamientos de composta superó estadísticamente a la de aquellos tratados con fertilizantes inorgánicos. Esta evidencia sugiere que el uso de fertilizantes orgánicos, ya sea de origen animal o vegetal, es una fuente benéf ica para los nutrientes del suelo con alto potencial en la agricultura sostenible.
