Material vs. Energy Recovery – An Assessment Using Computational Tools NERUDA and JUSTINE

The paper describes a continuing work on a unique approach of a Waste-to-Energy (WtE) Project assessment and related risk analysing. It is based on long time developed computational tools NERUDA and JUSTINE which support decision making in the field of waste Management.

This paper deals with recent improvement of in-house developed large-scale computational tools NERUDA and JUSTINE. The NERUDA tool provides support for strategic decision making in the field of waste management. The key part of NERUDA is a waste management related logistic problem. The logistic problem is solved by mathematical programming and is used to simulate competitive environment in waste management. The JUSTINE tool is an optimization model recursively applied to region divided into several sub regions and also their parts. The optimization model is used to obtain estimates of desired parameters that can be used for waste production, composition and calorific value prediction. A new important module representing current technologies for waste sorting – mechanical-biological treatment plant (MBT) and sorting line – are described in more detail in the paper.

The practical contribution of described computational tools is presented through a case study. The study is based on important outcomes of a comprehensive project of the Ministry of Environment of the Czech Republic, which describes regional waste management parameters on microregional level. The study also introduces the tool’s potential for abroad applications in countries with developing waste management (e.g. eastern markets).

Energetische Verwertung einer Feinfraktion aus der MBA durch pyrolytische Behandlung
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Die Pyrolyse ist ein seit Jahrzehnten bekanntes thermochemisches Verfahren mit welchem aus organischen Ausgangsstoffen (fossilen oder biogenen Ursprungs) feste, flüssige und/oder gasförmige Energieträger erzeugt werden können. Je nach Betriebsführung des Prozesses kann die Ausbeute des bevorzugten Produkts gesteuert werden. Im gegenständlichen Projekt wird die Erzeugung eines flüssigen Produkts hoher Energiedichte angestrebt. Als Einsatzstoff wird die Feinfraktion (< 25 mm) aus einer mechanisch-biologischen Abfallbehandlungsanlage (MBA), welche nach einer Intensivrotte (biologische Stufe) der Deponierung zugeführt wird, hinsichtlich ihrer Eignung untersucht.

CO2 calculation tool for sustainable green waste management
© European Compost Network ECN e.V. (6/2014)
CO2 calculation tool for sustainable green waste management This presentation will outline key features of an innovative and practical CO2 calculation tool, which allows to quantify CO2-effects of green waste processing and of application of derived products. Unique about the tool is that it does not only calculate CO2-effects of energy applications (e.g. use of wood chips as fuel or), but also accounts for CO2-effects of material re-use, most notably compost products. Optionally, the tool can take into account CO2-effects of innovative, biobased products from green waste.

Mechanical Dewatering of Digestate - Necessity and Potential

Anaerobic digestion has become an established component of mechanical and biological treatment of municipal solid waste. However, anaerobic digestion does little to reduce the mass of solid waste in the form of biogas.

MBT solution with windrow technology – investigations of the process performance

The worldwide demand for simple MBT solutions is still increasing. During the study and investigation for new projects as well as for improvement of already existing facilities there is a demand for layout and technological design of the biological treatment process.

Adaption of a German MBT Process to the Boundary Conditions of Newly Industrialized Countries - Results of a pilot plant operated in Thailand
© Wasteconsult international (5/2011)
A mechanical biological treatment (MBT) process for municipal solid waste (MSW), suitable for the boundary conditions of newly industrialized countries (NIC), was developed and tested in Thailand. The main purpose was to make the process simple, robust and economic. The process focuses on the production of refuse-derived fuel (RDF) and a high biogas yield. The so-called BIOBUNK pilot plant consists of a shredder as mechanical stage and an aerobic mixed reactor as biological stage.
