Applicability of multivariate data analysis to improve the sorting degree of recycled polyethylene
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The Circular Plastic Alliance Declaration of the European Commission targets the us-age of 10 million tons of recycled plastic per year into new plastic products in Europe by 2025 (European Commission 9/20/2019). To assist this objective this work focuses on the improvement of mechanical sorting of polyethylene (PE).

Combining laser cleaning and LIBS: fast and precise recycling of metal alloys
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
In respect of a limited amount of raw material, costs, CO2 and waste reduction, high precision metal recycling is getting more and more important these days. Contaminations of the melt with unwanted or outright detrimental elements (e.g. C, S, P, Cu or Pb in steel, Cr or Ni in low-alloy steels, Li in aluminium and so forth) are a huge liability toward the ‘‘alloy-to-alloy’’ recycling goal and essentially the only option in this case, is either costly dilution with clean raw materials, downgrading or worst case scenario discarding.

Brazilian waste management and its symbiosis to the cement market

The rules established by the National Policy for Solid Waste (PNRS), published in 2010, end the duality of the old system collection-disposal by introducing certain regulations and technological obligations which require greater technical complexity and mainly the introduction of Technology in the waste sector.

Emission reduction in the energetic utilization of agricultural
residues - combined reduction of PM and NOx

Biogenic residues offer a great potential for future climate-friendly energy supply. Compared with natural wood fuels the combustion of these residues causes relatively high emissions.

European Harmonization of Methods to Quantify Methane Emissions from Biogas Plants
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
In the past years, attempts were undertaken to quantify single emission sources as well as overall emissions from biogas plants using on-site (direct) and remote sensing (indirect) methods. While measurements on site often focus on one type of CH4 sources, remote sensing methods cover the overall emission plume. Among the current available emission measurement techniques, none is in a position to be recognized as the best international reference. Therefore, the establishment of a scientifically based standardization and harmonization of methods would greatly contribute to the assessment of the fugitive emissions from biogas plants.

Legal Aspects of Emission Reductions and Carbon Credits under Evolving Climate Finance Mechanisms in Brazil
© Lexxion Verlagsgesellschaft mbH (9/2016)
Brazil broke some ground by submitting an absolute GHG-reduction goal under the Paris Agreement, but the country must now cope with implementing the needed regulatory Tools promote public and private climate action. Climate financing has evolved substantially in the past years, ranging from crediting systems, to results-based payments, to carbon pricing instruments.

Modelling of Solid Recovered Fuel (SRF) Properties Based on Material Composition – Chloride Quality
© Thomé-Kozmiensky Verlag GmbH (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
© Thomé-Kozmiensky Verlag GmbH (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.

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.
