“…All the landfills currently operating are sanitary landfills equipped with landfill gas collection, energy recovery and a leachate collection system. Leachate treatment is performed both on site and off site (Di Maria and Sisani, 2017;Di Maria et al, 2018;Morello et al, 2016;Spagni et al, 2008).…”

A survey and a preliminary comparison were conducted between the waste management systems and schemes implemented in the Region of Umbria (Italy) and the West Bank (Palestine). The Region of Umbria operates in a wider political legal and economic supporting scheme, i.e., the one promoted by EU Directives. The West Bank showed all the typical economic, legal and political features of a developing country. From the economic point of view the incidence of the cost for waste collection and management with respect to the per capita GDP was 0.82% for the Region of Umbria and 1.2% for the West Bank. Although the incidence for the West Bank was higher, it was not enough to support the budget necessary for efficient waste management. A relevant aspect was the practically similar amount of organic waste generated per capita and per year in the two areas. The West Bank lacks infrastructures and adequate collection systems and there are no composting facilities. The number of mechanical sorting facilities was 0.034/10 5 inhabitants. The current recycling rate for the West Bank is about 6%. Some criticism about the sustainability of recycling and composting rates for the Region of Umbria are also highlighted. Some benefits for the West Bank, such as the introduction of home composting, are identified. This will affect both the amount and the costs of waste collected allowing the municipalities to allocate more money for separated collection of recyclables.

“…However, the phenomena that occur on the membrane surface (fouling and polarization of concentration) will be even more intense when the quantities of contaminants increase. Nonetheless, in the case of leachate, this increase in membrane process recovery would result in an increase in polarization concentration at the membrane surface, resulting in severe risk of fouling and lower efficiency of removal of effluent pollution parameters (Di Maria et al, 2018;Schiopu et al, 2012).…”

“…Reverse osmosis (RO) seems to be one of the most promising and efficient methods among existent processes for landfill leachate treatment used as the downstream stage of integrated treatment or integral treatment (Yao, 2013). Several studies have been using RO in the landfill leachate treatment (Cingolani et al, 2018;Di Maria et al, 2018;Dolar et al, 2016;Schiopu et al, 2012;Talalaj et al, 2019). In the early 2010s, Šír et al (2012) reported that RO-plants were installed in more than one hundred landfill sites in northern Europe, North America, and the Far East.…”

The reverse osmosis (RO) process has been increasingly applied to landfill leachate treatment. The published literature reports several studies that investigated the technical feasibility of RO. However, information about process costs is scarce. Also, companies that run leachate treatment plants do not provide actual costs. To fill this gap, this study aimed to evaluate the treatment costs of a full-scale RO for the treatment of landfill leachate located in Rio de Janeiro State, Brazil. A procedure was proposed to estimate the capital expenses (CAPEX), operational expenses (OPEX), and specific total treatment cost, the total cost per m3 of treated leachate, of the leachate treatment by membrane process, and the results obtained are discussed. The CAPEX for this full-scale RO was estimated at MUS$ 1.413, and OPEX ranged from US$ 0.132 to US$ 0.265 m−3 per year. The cost of leachate treatment has been estimated at US$ 8.58 m−3 considering the operation of the RO-unit for 20 years after landfill closure.

“…Values for energy, fuel and material consumption for the disposal of each Mg of waste in landfill were retrieved from the study of Doka (2009) ( Table 1). Treatment of the leachate generated from the landfill was assumed to be completely processed in an off-site wastewater treatment plant (WWTP) (Di Maria et al, 2018b;Renoun et al, 2008). Considering the very low level of organic residues, i.e.…”

The effectiveness of an existing integrated waste treatment plant aimed at the total recovery of waste to replace primary energy was investigated. The cumulative energy demand (CED) (MJ) was quantified using a life cycle approach. Mass and energy balances were determined for all the main inlet and outlet energetic and mass flows from the integrated plant. The current scenario was compared with a modified one where the amount of bio-waste processed was increased by using a new anaerobic digestion section for bio-methane production. The main results showed that there was a higher positive CED for the chemicals needed for operating the flue gas cleaning system. In particular urea gave the highest CED. In both the base and modified case the CED replaced by the recovered energy and fuels was higher than all the CED associated with the inlet flows, leading to a negative value of the net CED.
