This thesis describes research conducted to identify the best available technology for processing sourceâ€separated organic wastes, by means of a multiâ€criteria analysis (MCA): a) Environmental impact, b) cost, c) land area required, d) odor control and e) feedstock flexibility. A Lifeâ€Cycle Analysis (LCA) assessed the environmental impacts of each process. In conjunction with the financial and contextual (e.g., odor control) aspects that were examined in this study, this LCA compared four methods for disposing organic wastes: Three aerobic composting methods (windrow composting, aerated static pile, and inâ€vessel composting) and the use of yard wastes as Alternative Daily Cover (ADC) on a landfill. These methods were rated for each criterion and individual dominance scores were generated, using caseâ€specific weighting factors for each criterion. As a result, a decision making model was created that can help communities and waste management companies in choosing the appropriate technology for a particular situation.
The LCA study showed that both the ADC and the inâ€vessel technology were most beneficial for the environment. The ADC scenario was also found to be the least costly, at an estimated $14 per ton with windrow composting coming next with $22 per ton. The Gore Cover, for a specific application, was estimated at $42/ton. The invessel technology was by far the most costly method of all four, with $147 per ton. The aerated static pile technology was rated best in the other three criteria, i.e. area needed, odor control and input material flexibility. Based on applying different sets of weighting factors for all five criteria, two technologies were rated as most preferable: the aerated static pile (Gore Cover system) and the use of yard wastes as ADC in landfills. Of course, the latter depends on the availability of sanitary landfills and demand for ADC in the area.

Fremdstoffgehalte in den Sieblinien von Biogut nach Voraufbereitung

Fremd- und Kunststoffeinträge im getrennt erfassten Biogut rücken zunehmend in den Fokus des Gesetzgebers. Mit der Novellierung der BioAbfV treten zum 01.05.2025 erstmals Grenzwerte in Kraft, die sich auf das frische Biogut vor der biologischen Behandlung beziehen.

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.
