Dutch sustainable landfill research program: five years experience with the bioreactor test cell.

The project Sustainable Landfilling (NL) aims to assess the feasibility of three sustainable concepts, one of them is the bioreactor concept dominated by organic waste. The (anaerobic and aerobic) flushing bioreactor pilot in Landgraaf has been in operation five years and has additionally been simulated in a biological degradation and flushing model. The release of nitrogen seems to be delayed by the intermediate fixation in the form of biomass and stagnant zones. Because of the strict standards for the allowable nitrogen concentration from the viewpoint of emission control, the development of the nitrogen concentration is considered to be the main limiting factor to achieve final storage quality (FSQ) within the acceptable time-frame. Therefor the research has been extended to nitrification of the leachate recirculation flow and aeration of the bioreactor

The bioreactor start-up and first years of operation has been described previously (Brands- van den Esschert, 2003 and Woelders, 2005) and therefor will be summarized. The pilot was constructed with a rectangular footprint of 55x80 meter, with an average depth of approximately 6 meters (Figure 2). The landfill gas has been extracted. The top cover is permeable to permit rainfall entrance and is suitable for methane oxidation. The organic waste is a mix of municipal solid waste and comparable industrial waste.

Biological treatment of organic waste comprises two types: aerobic composting and anaerobic digestion, depending on the type of microorganism that converts the organic mass. Worldwide, composting is more frequently applied than digestion. Both processes replicate the natural degradation of biodegradable materials. The situation regarding biological treatment is significantly different between Europe and Asia in terms of substrates and technologies. The terms used for describing the biological treatment options are not always consistent between European and Asian professionals either.

Experimental Optimisation of Static Composting Reactors
© Wasteconsult international (5/2011)
This study focuses on investigations for process optimisation of static dynamic reactors of the mechanical-biological waste treatment. This contains the process as self and the increase of the transparency of the whole control system. To achieve this, measurement equipment for temperature, gas composition and pressure was developed.

Praxisorientierte Forschung auf dem Gebiet der mechanisch-biologischen Abfallbehandlung
© ANS e.V. HAWK (9/2009)
Die Errichtung von mechanisch-biologischen Abfallbehandlungsanlagen zählt in der Europäischen Union aus Gründen des Klimaschutzes zur nachhaltigen Abfallwirtschaft. Im Mittelpunkt steht dabei die Reduzierung der Treibhausgase aus den Hausmülldeponien, indem das Ablagern von unbehandelten Siedlungsabfällen verboten wurde. Strikte Anforderungen hierzu werden in Ausschreibungen meist generell abgefragt, somit liegen die Ausarbeitung der technischen Lösung, das verfahrenstechnische Konzept und das Risiko beim Anlagenbauunternehmen.
