Development of a methodology for the evaluation of different municipal solid waste anaerobic digestion technologies

This paper describes a methodological tool developed for the evaluation of different Anaerobic Digestion (AD) technologies for treating the Organic Fraction of Municipal Solid Waste (OFMSW).

Several such technologies have been proposed over the last years; when compared to biogas recovery from landfills, their main advantage is the stability in biogas production and the stabilization of waste prior to final disposal, whereas biogas recovery from landfills has the main setback that it extends over a great time period and may show significant fluctuations on biogas quantity and quality. AD technologies also show great adaptability to a broad spectrum of different input material beside OFMSW (e.g. agricultural and animal wastes, sewage sludge) and can also be used in remote and isolated communities, either stand-alone or in conjunction to other renewable energy sources. AD technologies follow different approaches to the AD process and also can include production of compost; furthermore, AD can substantially help meet the targets for organic waste disposal reduction. In the presented analysis, multicriterial analysis is used for the decision-making process, in which various economical, environmental and technological aspects are explicitly considered. In this context, the ELECTRE III method is implemented for comparing and ranking 5 selected alternative AD technologies.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens - ein Rechtsvergleich
© Lexxion Verlagsgesellschaft mbH (8/2024)
Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
