Impact factors and regulatory mechanisms for material flow management: Integrating stakeholder and scientific perspectives

Strategic management of WEEE in Switzerland—combining material flow analysis with structural analysis

“…The system grid is formed in this study only for the aggregated matrix. The aggregation of individual matrices was formed with a similar approach followed by Lang et al, (2006). First, the standard deviation of all seven different ratings for each of the 240 cells was calculated.…”

“…In this respect, expert interviews were conducted with the actors of the system and cross-impact analysis was used to reveal the dynamics of the recycling of WEEE in Switzerland. Although a similar approach was performed on bio-waste (Lang et al, 2006), to authors' best knowledge, no such study has been carried out on WEEE up to this date.…”

Evaluation of Replacing Natural Gas Heat Plant with a Biomass Heat Plant - A Technical Review of Greenhouse Gas Emission Trade-Offs

“…High (i.e. greater than 50%) moisture content is a prerequisite for having high levels of microbial activities [Lang et al, 2006]. Dispite the wide range of possible emissions; it is possible to describe general trends from composting.…”

Sustainability Potential Analysis (SPA) of landfills – a systemic approach: theoretical considerations

“…(Both pragmatic comparative approaches using thresholds or benchmarking and sustainability assessments aiming at ''absolute'' measures are possible) Model (ii) Model of a system that integrates: (i) energy-/material-/financial-flows; (ii) agent-networks and driving forces; and (iii) systemic interdependencies [61,62] Weighting of the criteria. Different MAUT (Multi-Attributive Utility Theory) techniques are applicable for this task: e.g., the simple attribute rating technique (SMART) [63] or the analytical hierarchy process (AHP) [64] Shell scenarios of contextual developments [65] Measured value (iv) Utility or hazard scores indicating the potential of a system to hinder or support SD with respect to systemic criteria Algorithms (v) v.i Rating according to a defined scale: e.g., distance to target/best alternative v.ii Different algorithms are possible to aggregate the utility or hazard scores: e.g., weighted sum, or fuzzy algorithms [66].…”
