“…The BW of the locality in study presented high content of uncooked FW (OviedoOcaña et al, 2013). According to literature (Kumar et al, 2010;Li et al, 2013), this type of FW possess special physico-chemical properties such as, organic substances easy-to-degrade, high Ntotal content, and low C/N ratio. In consequence, similar data were obtained for our BW.…”

“…This process could increase not only temperature up to thermophilic range (Sundberg et al, 2004) but also mesophilic phase duration . Additionally, starting controls A´ and B´ showed high moisture content (70.8% and 79.0% respectively) associated with FW (Adhikari et al, 2008;Li et al, 2013), which generally affect the porosity of the material, the oxygen diffusion and progress of the whole process (Krogmann et al, 2010).…”

“…Among them, adding bulking material (BM) or increasing aeration rate have widely been used (Sundberg and Jönsson, 2005;Epstein, 2011). Regarding to BM they have been used to modify physical properties of substrates, improving biological activity conditions and biodegradation kinetic (source of C, particle size, volumetric density [VD], porosity, and regulation of moisture) (Haug, 1993;Yang et al, 2013;Li et al, 2013).…”

“…For example, wheat residue pellets and chopped hay were used by Adhikari et al (2008), green wastes and cardboard paper by Francou et al (2008), raked leaves and grass clippings by Kumar et al (2010). Likewise, Li et al (2013) reported use of sawdust followed by sugarcane bagasse (SCB), rice husk, and wood shavings. Selection of appropriate BM should be accompanied by not only its physico-chemical characteristics but also its availability and costs related with its raw source.…”

Biowastes (BW), the main raw materials for the composting installations in developing countries, are characterized for containing uncooked food wastes (FW), high moisture content, low porosity, acidic pH, and low C/N ratios which affects the overall composting process (CP). In this study, we evaluated the effect of adding sugarcane bagasse (SCB) and star grass (SG) (Cynodon plectostachyus (K. Schum.) Pilg.) as bulking materials (BM) over the quality of the substrate, progress of the process, and quality of the obtained product. In this sense, two pilot-scale experiments were performed. The first one contained a substrate formed by 78% BW and 22% SCB (pile A). The second experiment contained a substrate formed by 66% BW and 34% SG (pile B). For each experiment, control treatments (piles A´ and B´ respectively) were performed by using 100% BW without BM. The results showed that in both cases the adding of BM improved substrate quality (pH, moisture, and total organic C content [TOC]), speeding up the starting step (2-3 d) and reducing the duration of the thermophilic phase of CP (3 d). However, the physico-chemical properties of both BM increased cooling and maturation phases duration (between 15 and 20 d). Obtained products quality was improved in terms of higher TOC, cation-exchange capacity, bulk density, and higher water holding capacity. Application of obtained products A and B could improve some soil properties like major nutrient, water retention, and increasing the organic matter.

Food waste residue is an intractable problem worldwide. The current study discussed the potential of adsorbents prepared from food waste residue (AFWR) for heavy metal removal from wastewater. The microstructure of AFWR was characterized, and kinetic studies on the simultaneous adsorption of Pb 2+ , Cu 2+ , Zn 2+ and Cd 2+ ions from aqueous solutions by AFWR were carried out. It was found that the adsorption of all heavy metals followed a pseudo-second-order kinetics, so that there was a competitive adsorption for Pb 2+ , Cu 2+ , Zn 2+ and Cd 2+ . According to the experimental results, the adsorption in competition beads with the heavy metals presented an order of Cu 2+ > Pb 2+ > Zn 2+ > Cd 2+ .
