“…The results of the environmental impact assessment highlighted an important role of personnel transport on the total amount of emissions. This is a common result obtained in similar studies applied to different sectors, when the analyzed system has low emissions; in these cases, secondary processes become important contributors to the total amount of emissions [59], while, in many other cases, the role of personnel transport is negligible in comparison with the overall emissions [60]. As travels were the major environmental hotspot in our analysis, the influence of travel distance was further investigated by two short-range (30 km) and long-range (750 km) scenarios to quantify the role of distance in terms of total emissions.…”

At forest sites, phytotoxic tropospheric ozone (O3) can be monitored with continuously operating, active monitors (AM) or passive, cumulative samplers (PM). For the first time, we present evidence that the sustainability of active monitoring is better than that of passive sensors, as the environmental, economic, and social costs are usually lower in the former than in the latter. By using data collected in the field, environmental, social, and economic costs were analyzed. The study considered monitoring sites at three distances from a control station in Italy (30, 400, and 750 km), two forest types (deciduous and Mediterranean evergreen), and three time windows (5, 10, and 20 years of monitoring). AM resulted in more convenience than PM, even after 5 years, in terms of O3 depletion, global warming, and photochemical O3 creation potential, suggesting that passive monitoring of ozone is not environmentally sustainable, especially for long time periods. AM led to savings ranging from a minimum of EUR 9650 in 5 years up to EUR 94,796 in 20 years in evergreen forests. The resulting social cost of PM was always higher than that of AM. The present evaluation will help in the decision process for the set-up of long-term forest monitoring sites dedicated to the protection of forests from O3.

“…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.

“…Recent efforts targeted LCA applications in the environmental assessment of waste management. Many of these efforts focused on developed economies (Di Maria and Sisani, 2017;Di Maria et al, 2016;Herva et al, 2014;Ripa et al, 2017;Thomsen et al, 2017;Tunesi et al, 2016) with limited applications on economies in transition or developing economies (Liu et al, 2017a(Liu et al, , 2017bNoya et al, 2018;Othman et al, 2013) where waste composition is different and management practices still concentrate on landfilling or open dumping (Laurent et al, 2014a(Laurent et al, , 2014b). In addition, most studies emphasized individual processes instead of integrated systems (Laurent et al, 2014a(Laurent et al, , 2014bTabata et al, 2010).…”

Solid waste management has witnessed much progress in recent years with considerable efforts targeting the reduction of associated impacts and carbon emissions. Such efforts remain relatively limited in developing economies due to inefficient management practices. In this study, a life cycle assessment (LCA) approach is adopted to identify integrated systems with minimal impacts and reduced emissions in a developing context coupled with an economic valuation and sensitivity analysis to assess the effect of varying influencing parameters individually. The results showed that the highest impact arises from landfilling with minimal material recovery for recycling and composting, while incineration coupled with energy recovery contributed to the least equivalent emissions (-111% with respect to baseline scenario) at a varying cost of −70% to +93% depending on the selected technology and the value of carbon credit. Optimizing material recycling, composting and landfilling with energy recovery contributed to 98% savings in emissions (with respect to baseline scenario) and remained economically attractive irrespective of the carbon credit exchange rate of 0.5-50 US$/MTCO 2 E. The sensitivity analysis showed that an improvement in landfill gas collection efficiency (up to 60%) can contribute to major savings in emissions (58%). The application of the LCA-based approach supports the development of integrated viable plans while quantifying advantages and disadvantages towards decision-making and policy-planning.
