Modelling of Solid Recovered Fuel (SRF) Properties Based on Material Composition – Chloride Quality
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Producing solid recovered fuels (SRF) is a well-established route for recovering energy resources from municipal solid waste (household and/or commercial). Chloride content critically impacts the quality of SRF. It directly influences operation of thermal processes, having deleterious effects through the high temperature corrosion of the boilers and through demands placed on the flue gas treatment (FGT) system, which could impact emissions control. Whereas design and specification of process plant can mitigate the technical issues associated with the presence of chloride experienced during thermal treatment, processing such fuels is associated with increased capital, operating and maintenance costs. This, at best, restricts the uptake/use of SRF or increases the cost of its treatment towards achieving a reduced chloride content.

CO2 Capture and Re-Use at a Waste Incinerator
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Recently a new innovative process developed by Procede Gas Treating B.V. has been commissioned at line 3 of the Twence plant, a Waste-To-Energy (WTE) plant located in the eastern part of the Netherlands. In this process the CO2, that usually is emitted to atmosphere, is in this new application, scrubbed from the flue gas and the obtained pure CO2 stream is used to produce a sodium bicarbonate slurry (SBC). Instead of the conventional SBC flue gas scrubbing process, where dry SBC particles are used, this SBC slurry will be injected to remove the acid components from the flue gas, before the gas is emitted to atmosphere. Due to the implementation of this process the carbon footprint of the Twence installation is reduced. The new SBC plant produces 8,000 tons of sodium bicarbonate annually and to produce this amount of SBC 2,000 ton per year CO2 is captured from the flue gas. The CO2 originates for about 50 percent from biomass.

Feasability Study of Capturing CO2 from the Klemetsrud CHP Waste-to-Energy Plant in Oslo
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
The municipality of Oslo by Energigjennvinningsetaten (EGE) was in December 2015 awarded funding from Gassnova – a state owned company that coordinates the Norwegian CCS-work – to conduct a feasibility study. The purpose of the feasibility study was to demonstrate at least one workable solution for carbon capture from energy recovery for waste, with technical descriptions, cost estimates, project plan and plan and budget for the next phase.

New Developments for an Efficient SNCR Monitoring and Regulation System by Evaluating the NOx Mass Flow Profile
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
When the SNCR process was introduced first in the eighties of the last century the focus was directed towards applying this low cost technology mainly in combustion plants where only relatively low NOx reduction rates were required. In these types of boilers, like waste-to-energy plants (WtE), the required NOx limits < 200 mg/Nm3 could be maintained easily. Today, NOx limits of 100 mg/Nm3 and lower can be achieved and guaranteed at all operating conditions for these applications. Therefore, the SNCR process represents the Best Available Technology (BAT) today. As a result, more and more owners of waste-to-energy plants take advantage of the low costs at comparable performance and replace their existing SCR system with SNCR.

Climate Protection - opportunity to ensure financial sustainability of solid waste management in developing countries
© Eigenbeiträge der Autoren (12/2013)
The vast majority of solid waste management (SWM) projects implemented in developing, emerging and transition countries (DETC) envisage the disposal of residual waste on a sanitary landfill. This approach leads in most cases to an increase of greenhouse gas (GHG) emissions. By implementing advanced SWM systems DETC could lower their national greenhouse gas balance by 10-15%.

Public Subsidies for CCS and EU State Aid Law: The Decisional Practice of the European Commission
© Lexxion Verlagsgesellschaft mbH (9/2012)
Technologies for the capture, transport and storage of CO2 (CCS) are under examination as promising tools to cut greenhouse gas (GHG) emissions. Given its high cost, however, CCS deployment has failed to gain momentum, and financial support from public authorities is potentially needed before the private sector can fully engage in this abatement technology. Under European Union (EU) law, such public support may constitute State aid and thus be subject to the stringent EU regime on State aid. This article examines the European Commission’s approach to assessing the compatibility of publicly-funded support for CCS projects with EU State aid law, looking at the limited case law available in this area as well as at the general legal framework used by the Commission when assessing aid for CCS projects.

Optimization of MBT considering Energy Efficiency and Protection of Resources and Climate

In 18 out of 46 MBTs in Germany biological treatment of organic-containing fine fractions takes place with the aim of achieving the deposition criteria exclusively through aerobic rotting. Thus energy potentials contained in the fine fractions are not utilized.

German GHG Mitigation Lighthouse Project MBT Plant Gaobeidian (PR China)

In June 2009, the German Federal Ministry of Environment granted a fund to the German company AWN Umwelt GmbH (Buchen) to establish a mechanical biological treatment plant in the City of Gaobeidian (PR China). The facility is seen as a lighthouse project for GHG mitigation.

Potential of the Microbial Methane Oxidation to Mitigate Low Gas Emissions of Mechanically and Biologically Treated Waste
© Wasteconsult international (5/2011)
In the framework of the MiMethox-project, financed by the Federal German Ministry of Education and Research, a process study on a MBT landfill is done. The results of a lysimeter study for qualitative and quantitative MBT landfill gas analyzes are introduced.
