TK Verlag - Fachverlag für Kreislaufwirtschaft Fully Automated Sorting Plant for Municipal Solid Waste in Oslo with Recovery of Metals, Plastics, Paper and Refuse Derived FuelDr.-Ing. Benjamin Eule
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.
TK Verlag - Fachverlag für Kreislaufwirtschaft Plastics Recycling and Energy Recovery Activities in Poland – Current Status and Development Prospects –Dr.-Ing. Kazimierz Borkowski
The waste disposal system in Poland is one of the least advanced in Europe. Despite great efforts over the last 20 years municipal waste landfilling has only reduced from 95 percent in 1991 to 73 percent in 2010. This still means that millions of tonnes of post-consumer waste continue to be landfilled.

TK Verlag - Fachverlag für Kreislaufwirtschaft Communally Funded Waste Treatment PlantsDr.-Ing. Alexander Gosten
Communally funded waste disposal in Germany was a major achievement of the 19th century. Until then, all waste was simply thrown out. Proper disposal helped combat epidemics and diseases that posed a major problem in those days. The creation of hygienically bearable conditions was an intrinsic task of the waste disposal service. For more than 100 years now, waste incineration has also been communally funded. More than 100 years ago, the first plant began operation in Hamburg.

Wasteconsult international Quality Improvement in RDF and Other Non-metallic Products through Magnet and Sensor SortingDr.-Ing. Ulrich Kohaupt
Solid waste has become a material source for various applications, such as Residue Derived Fuel (RDF), polymers, or wood for chip board production. The removal of components which reduce quality is essential for the widespread use of these materials. A recent feature of sensor sorting systems is magnetic separation, which has become a must for quality-assured RDF. State-of-the-art technologies include inductive sensoring, x-ray transmission and near infrared spectroscopy.

European Compost Network ECN e.V. Evaluating the interaction of transport mechanisms through dairy manure to determine the effects on ammonia and greenhouse gas emissionsMarlyse K. Williams, Tom L. Richard, Eileen Fabian Wheeler
Several studies have previously investigated methods to reduce gas emissions from dairy slurry systems, but few studies have evaluated emissions from semi-solid manure systems or what promotes gas release from semi-solid manure stacks.
IWWG International Waste Working Group INDUSTRIAL WOOD WASTES: EXPERIMENTAL CHEMICAL-PHYSICAL CHARACTERISATION AND NONCONTROLLED COMBUSTION TESTSDr.-Ing. Fabio Tatàno, L. Barbadoro, F. Mangani, F. Mangani, S. Pretelli
According to the waste framework directive 2006/12/EC, the European Union’s approach to solid waste management is based on the integrated hierarchy system consisting of: firstly, the prevention or reduction of waste production and harmfulness; secondly, the material waste recovery, or the waste use as a source of energy. Moreover, expressly in line with Annex I of the mentioned directive containing the list of waste categories, this integrated hierarchical management approach should also be implemented for industrial process residues.
IWWG International Waste Working Group COMPARATIVE EVALUATION OF SRF AND RDF CO-COMBUSTION WITH COAL IN A FLUIDISED BED COMBUSTORAnurag Garg, Richard Smith, Dr Phil Longhurst, Prof. Simon Pollard, Dr Nigel Simms
Increasing fossil fuel prices and greenhouse gas (GHG) reduction requirements compels energy users to utilise cost effective materials that also have a significant biomass fraction. The biomass fraction is considered ‘carbon neutral’ and does not contribute towards GHG emissions. The UK, like many Member States, is facing challenging landfill diversion targets for BMW (biodegradable municipal waste) to fulfil the Landfill Directive (Council Directive, 1999) requirements (Garg et al., 2007). According to the latest data, the UK landfilled ca. 62% of total MSW in 2005-06 (Defra, 2006).
IWWG International Waste Working Group SECOND GENERATION METHODOLOGY FOR CHEMICAL CHARACTERIZATION OF SOLID WASTE FRACTIONSPh.D. Fellow Christian Riber, Thomas Astrup, T.H. Christensen
Modeling waste management systems requires quantification of important emissions from the waste treatment alternatives included in the assessment. For most treatment technologies (e.g. waste incineration and mechanical-biological treatment), emissions are depending on the composition of the waste input. Without appropriate composition data, misleading conclusions may arise from the assessment thereby facilitating unjustified decisions. This is just one example of the use of waste chemical composition, but many other applications exist and the lack of welldocumented data concerning solid waste fractions is evident as reported in e.g. /Burnley S.J. (2007)/. (Session A5: Waste characterisation)
IWWG International Waste Working Group LIFE CYCLE ASSESSMENT OF MSW RECYCLINGMario Grosso, L. Rigamonti, M. Giugliano, Prof. Stefano Consonni
The municipal solid waste (MSW) generation in Italy in 2005 was 31.7 million metric tones, corresponding to an average of 539 kg per capita. In the same year, the source - separated collection of recyclables and compostables was equal to 24.3% of the total Italian MSW production (APAT-ONR, 2006). (Session A10: Waste recycling (II))
IWWG International Waste Working Group ANALISYS OF STRUCTURE OF WASTE EMISSION IN TOKYO BY INTERREGIONAL WASTE INPUT-OUTPUT TABLEM. Tsukui
Waste generation is inevitable accompanied with economic activities. It is necessary for dealing with the waste problem to clarify the relationship between economic activities and waste generation. Input-output analysis is a conventional method to describe the flow of goods and services among different sectors of the economy. Recent years, new usefulness was found in input-output analysis as an effective method for LCA, especially for the waste treatment problem. There are pioneering research works by Professor Leontief which develop the conventional input-output analysis to deal with the flow of waste (Leontief, 1970, 1972, & Duchin, 1990). Nakamura and Kondo et al. also adopted this method to extend the conventional input-output model to the waste input-output model, which was called WIO (Kondo et al., 2002).

IWWG International Waste Working Group SYSTEMS FOR CONVERSION OF WASTE BIOMASS TO ENERGY IN JAPANR. Inaba, Masahiro Osako, Hidetoshi Kuramochi, Minoru Fujii
Biomass has been predicted to become an alternative to fossil fuels, not only to prevent global warming but also to preserve fossil fuel resources. Waste biomass, in particular, has bee predicted to become an alternative fuel in Japan, owing to the volume produced. This paper estimates the biomass potential in Japan and then presents the current situation with regard to biomass conversion. We then consider combined conversion systems employing biological conversion and thermal conversion as possible means of improving the efficiency of biomass conversion systems. Finally, the energy efficiency and CO2 emission of several systems are compared.
