Sustainability Assessment for Advanced Biofuel from Waste Wood Integrated in the Steel Industry

The global steel production is the neck of the industrial civilization. Almost any produced good and service needs inputs that are directly or indirectly made of steel. However, the production of steel has not only major impacts on the overall economy.

Plastics Recycling and Energy Recovery Activities in Poland – Current Status and Development Prospects –
© TK Verlag - Fachverlag fĂĽr Kreislaufwirtschaft (9/2016)
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.

Fully Automated Sorting Plant for Municipal Solid Waste in Oslo with Recovery of Metals, Plastics, Paper and Refuse Derived Fuel
© TK Verlag - Fachverlag fĂĽr Kreislaufwirtschaft (9/2016)
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.

Study on biodegradability of wood residues
© European Compost Network ECN e.V. (6/2014)
Bark and timber residues (waste wood) mingled with soil, dirt and stones have so far been landfilled without any alternative use. The aim of this study was to propose a technology for biological treatment of this waste, enabling to produce quality compost.

Communally Funded Waste Treatment Plants
© TK Verlag - Fachverlag fĂĽr Kreislaufwirtschaft (3/2010)
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.

The adsorption of Cd(II) ions by poplar wood sawdust

The biosorption of cadmium (II) by raw and poplar wood sawdust modified with 1% NaOH at room temperature was studied in a batch system. The modified poplar wood sawdust had higher adsorption capacity for about five times, and adsorption affinity for about twenty times related to unmodified one.

Quality Improvement in RDF and Other Non-metallic Products through Magnet and Sensor Sorting
© Wasteconsult International (6/2009)
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. Keywords: Magnetic sorting, eddy current separation, sensor sorting systems, residue derived fuel, wood recycling 1 The Source of Raw Material 2 The Process 3 Sorting Solutions To Date:Magnetic Separation in the Broader Sense 3.1 Suspension Magnets 3.2 Eddy Current Separators 4 Sensor Sorting Systems open up New Possibilities 5 Conclusion
