Regenerative Energie
The DiCOM® process, developed by Organic Resource Technologies Ltd, is a novel, rapid (19 day), biological, municipal solid waste (MSW) treatment process which produces biogas and a stable compost as final end-products.
The process combines aerobic composting with anaerobic digestion in a sequencing batch reactor. Two sister laboratory-scale DiCOM® reactors, fed with the organic fraction of mechanically sorted municipal solid waste (C:N 18:1; TVS 56%) were operated to enable the transfer of anaerobic inoculum from one reactor to the other (direct transfer). The direct transfer of anaerobic inoculum provided a reduction in overall acidification, improved bio-methanation, with a more rapid onset of prolonged methane production, increased the mean biogas production rate by 58% (28.7 L/day/kg of TVS) and increased total solid degraded (from 41 to 45% of TVS) during the anaerobic phase. An electron balance showed that the direct liquor transfer provided a 50% increase in electron flow during the digestion phase which provides a significant energetic advantage to the process. The compost was found to be more stable (self-heating test) than the control, which is consistent with greater destruction of organics. It is anticipated that enhanced solid degradation from the direct transfer of anaerobic inoculum is due to the transfer of active microbial communities and/or biologically active species.

Fremdstoffgehalte in den Sieblinien von Biogut nach Voraufbereitung
© Witzenhausen-Institut für Abfall, Umwelt und Energie GmbH (11/2024)
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.
