Two TRAINING COURSES have been arranged under the supervision of leading International Experts on Tuesday 27th September, 2016 prior to the opening of the Conference.
Courses are open to all Conference Participants and a Certification of attendance will be distributed at the end of each course.The official language of the Training Courses is English.
Registrations are to be made using the Registration Form for conferences fees by checking the option "Participation in the IWWG Training Courses" given in the form. For details on registration click here.
Training Course I: Special Waste to Energy (SP-WTE)
Organized by: Prof. Dr. Karl E. Lorber, Montan University of Leoben (AU)
During this course the utilization of Solid Recovered Fuels (SRF) as main burner fuel (MBF) during manufacturing will be presented. In general, when a multiple stage: crushing, classifying and sorting – process is applied in a SRF processing plant, a premium quality feedstock for the main burner at kiln outlet and a regular quality input material for the secondary firing system at kiln inlet, can be recovered as substitute fuels that could be used for substitution of conventional fossil fuels like hard coal, heating oil and petrol coke.
The connection with the desired high heating values on the one hand and requested low pollutants content (especially: Chlorine) as well as reasonable recovery rates on the other hand becomes a conflict of interest. Utilization of Solid Recovered Fuels (SRF) as substitute fuel in the clinker process of cement plants has become state of the art.
For this reason the thermal substitution rate of fossil fuel by RDF in Cement Industry will be examined and the 100% substitution of fossil fuel will be discussed further as it seems to be basically possible, when an optimized feedstock mix of special waste such as animal fat & bone meal, used solvents, SRF etc. is fed at kiln outlet side (main burner) and scrap tyres are fed at kiln inlet side (secondary burner).
This lecture will include:
The legal requirements (EU-Waste Framework Directive)
The waste properties and technical specifications
The production of SRF for co-incineration plants
The quality assurance and utilization of Refuse Derived Fuels (RDF) and
Solid Recovered Fuels (SRF) as alternative fuel in the cement industry
Training Course II: Remediation of Old Landfills
Organized by: Dr. Marco Ritzkowski, Hamburg University of Technology (DE)
A great number of landfills have been operated during the last century and closed after they have reached their final capacity. This regards mainly those sites for deposition of Municipal Solid Waste (MSW), but also landfills which have been filled with industrial and hazardous waste (or mixtures of both) or non-hazardous wastes. In Germany, many MSW landfills have been closed since 2005 in consequence of adaptations made to waste legislation (MSW pre-treatment commitment and stringent standards for landfill operation, e.g. regarding required barriers). Today, a significant share of these closed landfills still emit landfill gas (LFG) and polluted leachate, caused by long term anaerobic biodegradation processes in combination with a lack of sufficient protection barriers. Moreover, a number of hazardous waste landfills had to be remediated in the past whereat remediation measures often continue at present. In some exceptional cases these sites are nowadays subject to landfill mining activities, aiming at a complete removal of the waste and its hazardous potential.
According to the legal situation outlined in the European and German legislation, landfill emissions have to be controlled, both before and after landfill closure. This includes –beside others – the collection and treatment of polluted leachate as well as the control of LFG emissions, potentially over very long time periods and associated with noticeable costs for the landfill operator. The latter becomes of particular importance once options for LFG utilization (mainly heat and electrical energy production) are no longer feasible or, at least, no longer economically beneficial anymore.
The application of in-situ aeration measures at this stage aims at both the avoidance or minimization of current emissions and an accelerated and sustainable reduction of the remaining emission potential. The overall intention behind these activities is the reduction in landfill aftercare, both in terms of finances and efforts.
For others sites, which cannot be remediated by means of biological processes, securing measures may have to be applied. These measures range from the concept of encapsulation to a long lasting active treatment of soil and water which are contaminated by the landfill emissions.
The training course will address multiple issues related to landfill remediation and aftercare (technical measures for emission control and reduction, legal obligations, and methodologies for biological landfill stabilization) with possibilities for discussion of specific aspects.
