An integrated mathematical model for co-composting of agricultural solid wastes with industrial wastewater

Mathematical modeling of olive mill waste composting process

“…The heat balance equation in the composting model is defined by (Mason, 2006;Vlyssides et al, 2009;Zhang et al, 2010):…”

“…The composting process has been extensively studied by using urban solid wastes (Hamoda et al, 1998;Zhang et al, 2012), agricultural wastes or greenhouse residues (Agamuthu et al, 2000;Alkoaik and Ghaly, 2006), rice and rice husks (Gomes and Pereira, 2008), bovine manure (Gil et al, 2011) and olive mill solid waste (Muktadirul Bari Chowdhury et al, 2014) and by mixing different kinds of solid wastes (co-composting), such as food residuals with yard trimmings and chicken manure, etc. (Elwell et al, 1996;Paredes et al, 2002;Vlyssides et al, 2009).…”

“…This simplified modeling approach, including only OM change, has been used by many researchers in the composting process of olive mill wastes with different bulk agents Garcia-Gomez et al, 2003;Sánchez-Arias et al, 2008;Serramiá et al, 2010). To date, limited modeling studies (Vlyssides et al, 2009) have been conducted to describe the main physicochemical and biological mechanisms involved in the composting process of olive mill wastes. However, still there is a lack of information about the values of kinetic parameters that could describe simultaneously the composting of olive mill waste with different materials as bulking agents.…”

Dynamic modeling the composting process of the mixture of poultry manure and wheat straw

“…Composting is an organic matter decomposition process under aerobic conditions (Vlyssides et al, 2009). During the process, various microbial populations transform the initial organic matter into compost.…”

Effect of temperature and aeration rate on co-composting of olive mill wastewater with olive stone wooden residues

“…The solid residue during co-composting process is hydrolysed and consequently its total mass is reduced. Assuming that the hydrolysis of OSWR followed a first order kinetics, the hydrolysis constant was estimated (Vlyssides et al 2009). By this way, it is possible for the PLC to estimate at each time interval the mass of OSWR present in the composter and thus calculate the necessary wastewater addition in order to maintain the moisture of the system constant.…”
