“…According to ISO (2006) guidelines, LCA must evaluate the potential impacts of a product throughout the whole product life (cradle-to-grave). When this technique is used to assess WMSs, however, system boundaries are to be reshaped in order to include only processes starting when materials become waste, without considering the potential impacts generated before this point (Consonni et al 2005). Accordingly, our model starts from waste collection and ends with final recycling or disposal.…”

Background, aim, and scope\ud Many recent studies on waste management have described in detail the potential impacts of recycling and final treatment of municipal waste. In public debates the attention has also been focused on the choice of final disposal technologies (e.g., landfilling vs. incineration). However, a comprehensive assessment of the impacts of waste collection and transport was still lacking. In the present study we use LCA to evaluate the potential impact of the provincial waste management plan of Varese (northern Italy). A particular attention is devoted to the estimation of environmental impacts generated during waste transport.\ud \ud Materials and methods\ud A detailed Life Cycle Inventory was built for the transportation phase, based on primary data collected by interviewing the agencies involved in waste collection. To model the recycling and final disposal phase we relied on the BUWAL 250 database. Impacts were evaluated with the Eco-Indicator 99 method in its egalitarian formulation.\ud \ud Results\ud The results of our analysis reveal that the major potential impacts of the plan are associated with waste collection and transport. These impacts are partially compensated by reduced resource consumption through recycling and energy recovery through incineration. Discussion The outputs of the LCIA were compared with those obtained by using other ecoindicators (Eco-Indicator 99 hierarchist and individualist, CML2, EPS2000). Although not comparable on a quantitative basis, they are qualitatively consistent.\ud \ud Conclusions\ud Neglecting the effects of collection and transport might result in a severe underestimation of the environmental impacts of a waste management system, especially as refers to depletion of fossil fuels, emission of respiratory inorganics and climate change. To reduce the environmental impact of waste management systems an accurate optimisation of waste transport is required.\ud Recommendations and perspectives Effective waste management planning requires the explicit inclusion of waste collection and transport when comparing alternative management policies.\ud ISI CON REFEREE\ud P.248-25

“…Therefore a substantial reduction in final volumes of waste could be achieved, while the recovered material and resources could be used to generate revenues, which can fund the waste management further actions (Consonni et al 2005;UNEP 2009c).…”

Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

“…The environmental and economic assessment of energy recovered from waste as well as comparison of different waste treatment options has been performed in this type of models [13,14]. Several computer models have been developed to calculate recovery rates, costs and emissions of MSW management systems.…”

Concern about global warming calls for an advanced approach for designing an energy system to reduce carbon emissions as well as to secure energy security for each country. Conventional energy systems tend to introduce different technologies with high conversion efficiency, leading to a higher average efficiency. Advanced energy systems can be achieved not by an aggregate form of conversion technologies but by an innovative system design itself. The concept of LCS (low carbon society) is a unique approach having multi-dimensional considerations such as social, economic and environmental dimensions. The LCS aims at an extensive restructuring of worldwide energy supply/demand network system by not only replacing the conventional parts with the new ones, but also integrating all the necessary components and designing absolutely different energy networks. As a core tool for the LCS design, energy-economic models are applied to show feasible solutions in future with alternatives such as renewable resources, combined heat and power, and smart grid operations. Models can introduce changes in energy markets, technology learning in capacity, and penetration of innovative technologies, leading to an optimum system configuration under priority settings. The paper describes recent trials of energy models application related to waste-to-energy, clean coal, transportation and rural development. Although the modelling approach is still under investigation, the output clearly shows possible options having variety of technologies and linkages between supply and demand sides. Design of the LCS means an energy systems design with the modelling approach, which gives solution for complex systems, choices among technologies, technology feasibility, R&D targets, and what we need to start. low carbon society (LCS), energy systems, systems approach, clean energy technologies, energy models Citation:Nakata T, Rodionov M, Silva D, et al.
