Separation of contraries during the treatment of biowaste prior to wet fermentation
© Wasteconsult international (5/2017)
An efficient biological treatment of source separated organic waste from household
kitchens and gardens (biowaste) requires an adequate upfront mechanical preparation. This typically includes a separation of physical, non-organic contaminants like glass, plastics, etc. which otherwise might end up in the compost or digest.
Practices and Problems in MSW Management for Bio-Waste in Turkey

Regarding the integrated solid waste management in Turkey, tremendous efforts have been given to the transposition and implementation of related EU directives. The “By-law” on General Principles of Waste Management (05.07.2008), the “By-law” on Landfilling of Waste (26.03.2010) and many others have been enacted and the management of municipal solid wastes and other special and hazardous wastes has been improved.
Fully Automated Sorting Plant for Municipal Solid Waste in Oslo with Recovery of Metals, Plastics, Paper and Refuse Derived Fuel

In order to treat household waste Romerike Avfallsforedling (ROAF) located in Skedsmorkorset north of Oslo, Norway required the installation of a mechanical Treatment facility to process 40,000 tpa. Together with a Norwegian based technical consultancy Mepex and German based technical consultancy EUG the project was tendered and the plant build against a technical specification. In 2013 the project was awarded to Stadler Anlagenbau and since April 2014 the plant is in operation with an hourly throughput of thirty tons. The input waste contains specific green coloured bags containing food waste which is collected together with the residual waste from the households. The process recovers successfully the green food bags before the remaining waste is mechanically pre-treated and screened to isolate a polymer rich fraction which is then fully segregated via NIR technology in to target polymers prior to fully automated product baling. Recoverable Fibre is optically targeted as well as ferrous and non-ferrous metals. All food waste is transported off site for further biological treatment and the remaining residual waste leaves site for thermal recovery. In 2015 the plant has been successfully upgraded to forty tons per hour and remains fully automated including material baling.
Future Fuels from Residual Biomass

Already at an early stage of biofuels development and production it became obvious, that a potential competition to food and feed production could occur, supported by a number a potential studies and systems analysis. Based on their results a concept was derived for the use of the vast amounts of low grade, residual biomass for use in large scale synthetic biofuels production.
Conversion of the MBT plant at Gescher into a combined residual and organic waste treatment plant
© Wasteconsult international (5/2015)
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.
