“…Moreover leachate recirculation can even enhance ammonification, resulting in an increased ammonia concentration compared to traditional landfills (Berge et al, 2006;Long et al, 2009a;Price et al, 2003). This increase often causes the partial or complete inhibition of methane production, increases the costs for leachate treatment, and may create a significant long-term impact (Cossu et al, 2016).…”

“…where V C,t -volume of methane produced in the interval between t and t À 1; C C,t , C C,tÀ1 -methane concentrations measured at times t and t À 1; V G,t -volume of biogas produced between time t and t À 1; V H -volume of the headspace of reactors. In phase thermophilic III, biogas generated from each reactor was collected using a 10 l Tedlar Ò sampling bag connected to the upper gas port, and biogas volume was measured daily by means of a volumetric flow meter (Cossu et al, 2016). Methane and carbon dioxide composition in the gas were determined using a gas chromatographer (Hewlett Packard 5820).…”

An overall interaction is manifested between wastewater and solid waste management schemes. At the Laboratory of Environmental Engineering (LISA) of the University of Padova, Italy, the scientific and technical implications of putting into practice a decentralized waste and wastewater treatment based on the separation of grey water, brown water (BW - faecal matter) and yellow water (YW - urine) are currently undergoing investigation in the Aquanova Project. An additional aim of this concept is the source segregation of kitchen waste (KW) for subsequent anaerobic co-digestion with BW. To determine an optimal mixing ratio and temperature for use in the treatment of KW, BW, and eventually YW, by means of anaerobic digestion, a series of lab-scale batch tests were performed. Organic mixtures of KW and BW performed much better (max. 520mlCH/gVS) in terms of methane yields than the individual substrates alone (max. 220mlCH/gVS). A small concentration of urine proved to have a positive effect on anaerobic digestion performance, possibly due to the presence of micronutrients in YW. When considering high YW concentrations in the anaerobically digested mixtures, no ammonia inhibition was observed until a 30% and 10% YW content was added under mesophilic and thermophilic conditions, respectively.

“…Water content and pH level play an important role in conditioning the environment to make an ideal condition for bacterial activity. With leachate recirculation and addition of water and aeration, these ideal conditions can be achieved [6]. These two factors also distinguish bioreactor landfills and conventional landfills [7].…”

“…According to [9], there are 3 types of bioreactor landfills, namely aerobic, anaerobic, and hybrid. Among them, anaerobic bioreactor is often used because the presence of methane gas generation during the biodegradation process, the second is aerobic bioreactor, able to support the occurrence of faster biodegradation due to the addition of aeration, while the hybrid bioreactor is a method that is still used in small amounts [6], [10].…”

Municipal Solid Waste Management Using Bioreactor Landfill in the Treatment of Organic Waste from Jatibarang Landfill, Semarang-Indonesia

Landfilling is one of the easiest methods to be applied in the management of municipal solid waste (MSW). In its development, bioreactor landfill methods that have various advantages over conventional landfill emerge. This experiment aims to study the use of bioreactor landfills for the management of organic waste in Jatibarang Landfill, Semarang-Indonesia. There are 4 bioreactor landfills operated: 2 anaerobic bioreactors with leachate recirculation and addition of water, and 2 aerobic bioreactors. Different results are shown from these two types of bioreactor, where aerobic bioreactors reach peak temperatures (55oC each) faster even though anaerobic bioreactors reach higher temperatures (60oC and 61oC respectively). Anaerobic bioreactors reach a higher final pH value than aerobes while the accumulation of nitrogen content from an aerobic bioreactor is 2 times higher than anaerobes.
