Conversion of the MBT plant at Gescher into a combined residual and organic waste treatment plant

The Waste Management Company Westmünsterland “EGW” has a mechanical biological waste treatment plant (MBT-plant) for the pretreatment of residual waste in preparation to its disposal in landfills, which was put in operation in 2000. The MBT plant was converted in 2005 to meet new legal requirements. A regenerative thermal oxidizer (RTO) has been added to the biofilter for thermal exhaust air treatment and the tunnel composting was supplemented by an aerated windrow composting unit. Since 2012, theMBT plant was converted towards the biological treatment of separately collected organic waste.

The prerequisites for this step were created by cooperative Agreements between the districts of Borken and Recklinghausen and the city of Dortmund. The responsibility for the treatment of separately collected organic waste was transferred by the city of Dortmund and the district of Recklinghausen has been to the district of Borken, which delegated the task to its affiliated company, the EGW. By processing contingents from Dortmund, 50 per cent of the MBT plants were converted towards the treatment of organic waste in 2012. In 2014, a full conversion of the treatment of the organic waste was achieved, as additional organic waste was accrued from the district of Recklinghausen. Due to these changes, the RTO could be decommissioned. In future the exhaust air will be cleaned by the present biofilter. Since 2014, the residual waste from the district of Borken is only subjected to mechanical treatment and subdivided into high- and low-calorific fractions for thermal recovery in RDF (Refuse Derived Fuels) plants and incineration plants.

Klimabilanzielle Betrachtungen vor dem Hintergrund sich ändernder Substratzusammensetzungen

Die Berliner Stadtreinigungsbetriebe (BSR) sind als landeseigene Anstalt öffentlichen Rechts für die Abfallentsorgung und Reinigung einer Fläche von 890 km2 mit 3,4 Mio. Einwohnern verantwortlich. Im Rahmen der Sammlung (400.000 aufgestellte Abfallbehälter) werden rund 19 Mio. Entleerungen pro Jahr durchgeführt. Als Bürgerservice gibt es in Berlin 15 Recyclinghöfe und 6 Schadstoffsammelstellen, auf denen rund 150.000 t Abfall bei rund 2,8 Mio. Kundenbesuchen pro Jahr) angeliefert werden.

The APECS-biomass model
© Wasteconsult International (5/2015)
Organic wastes in all their different shapes and compositions have gained significant commercial, political and academic interest during the last decade. The main driver for this development is the widely accepted consideration of organic wastes as valuable resources rather than problematic or worthless stuff. With the aim to turn the economy from its fossil basis into a bio-economy with presumably higher resource efficiency and less negative or even positive climate impact, governments in many countries have startedto support the use of waste biomass in many ways including subsidies.

SolidWasteSim – Simulation of solid waste treatment
© Wasteconsult International (5/2015)
A critical analysis of mechanical processes in waste treatment plants hints at vulnerablespots in the interaction of plant units and deployed heterogeneous materials. The Simulation of mechanical processes in waste treatment may depict the total material flow in a plant and as such, contribute to a better understanding of the behaviour in heterogeneous materials, to identify bottlenecks, to check plant modifications and hence, to Support planning and reducing time for implementation period.

HTC: Key technology in Biomass waste treatment
© Wasteconsult International (5/2015)
Hydrothermal carbonization is the physiochemical process by which organic waste materialis converted into HTC biocoal and process water in a wet procedure at about 230 degrees temperature and 25 bar pressure within several hours. Hydrothermal carbonization is the industrial reproduction of the natural process by which biomass has been converted into fossil coal for millions of years. In this paper and in the presentation of Alfons Kuhles is the procedure of “Hydrothermal carbonization” explained, the GRENOL continuously operating HTC reactor, the mass energy balance of the GRENOL HTC procedure, usages and benefits of Hydrothermal carbonization as compared to the more established procedures of combustion, fermentation and anaerobe conversion (e.g. biogas production). In sum, HTC offers a new alternative procedure to process organic waste in an environmentally friendly manner, and to close the cycle of waste Management.

Post-treatment of Composting Leachate by Photocatalytic Process
© Wasteconsult International (5/2015)
In this study the capability of UV-ZnO photocatalytic process as a post Treatment method for composting leachate was examined at laboratory scale and in batch mode. The effect of some factors such as initial pH, oxidant concentration, light intensity and reaction time on the removal of organic load and color of leachate were investigated. Biological pre-treated leachate samples were collected from the effluent of leachate treatment facility of a composting plant in north of Iran. A Plexiglas column with 110 mm inner diameter and 300 mm height were used to conduct experiments. UVC lamps with different power levels in the range of 8-40W at the centre of the column were used as the source of irradiation. Based on the results of experiments, after 180 minutes of Radiation with 32W UVC lamps in pH 11 and in the presence of 1g.L-1 of slurry ZnO, maximum COD and color removal were achieved to be 57% and 67%, respectively.
