Residual municipal waste composition analysis – New methods for Czech waste management
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Relevant information about MW composition and proper forecasting of MW composition is crucial for relevant technical and economical modelling and business planning in the field of waste management. These include techno-economical models of MW treatment units, e.g. sorting line, transfer station, energy recovery, waste collection and transport or a regional waste collection and treatment system modelling (Kropáč et al. 2018) and complex business models concerning specific investments in waste management. In this context, there is a project under the Ministry of Environment of the Czech Republic.

Influence of pre-screening before ballistic separation on NIR-sorting quality of plastic rich 3D-fractions out of MCW

The exploitation of plastics gains more importance over time. In this con-text, material recycling is especially focused on packaging plastics. A further waste stream that contains a significant amount of plastics is mixed commercial solid waste. To assess the potential of plastics for recycling and energy recovery from these waste stream large-scale experiments were conducted. The potential of mechanical pre-processing with the aim of generating a 3D-plastics pre-concentrate was assessed. The focus of these investigations was put on the relevance of the screening stage and its influence on down-stream material processing via ballistic separation and sensor-based sorting. Results demonstrate not only that the screening of the waste leads to enrichment of plastics in coarse particle size ranges (especially > 80 mm) and transfer of contaminants, organics and minerals to fine fractions (especially < 10 mm), but also that sensor-based sorting performance can be significantly enhanced due to cleaning effects on plastics, induced by the material circulation and friction in a drum screen.

We are aware of the current strong interest in the energetic utilisation of waste-derived fuels (WDF). Rising energy costs are also boosting the substitution of fossil fuels with WDF.

Treatment of Municipal Solid Waste before Anaerobic Digestion - CAPEX and OPEX as model calculation
© Wasteconsult International (5/2011)
Treatment of Municipal Solid Waste (MSW) before Anaerobic Digestion (AD) is highly considerable in terms of capital expenditure (CAPEX) and operational expenditure (OPEX). The paper determines different treatment options like “Standard” and “AdvancedBioSolids” and characterizes the treatment options. The “Standard“ option is relatively simple and comprises only few process steps. The “AdvancedBioSolids” option is more complex and refines the biosolid fraction by sorting of inorganic items and other non-digestibles in a multi-stage dry refining process.
