The presence, emission and partitioning behavior of polychlorinated biphenyls in waste, leachate and aerosols from Norwe...
Even though production and open use of polychlorinated biphenyls (PCBs) have been phased out in Western industrialised countries since the 1980s, PCBs were still present in waste collected from different waste handling facilities in Norway in 2013. Sums of seven indicator-PCBs (I-PCB7:PCB-28, -52, -101, -118, -138, -153 and -180) were highest in pl...
Cobalt in end-of-life products in the EU, where does it end up? - The MaTrace approach
The use of cobalt has experienced a strong growth in the last decades. Due to its high economic importance and high supply risk, it has been classified as a critical raw material for the EU and other economies. Part of the EU's strategy is intended to secure its availability, through fostering its efficient use and recycling. The latter is affected...
Post Syrian-war material recovery, reuse and transformation in the Old City of Aleppo
Purpose: Eight years of civil war in Syria severely impacted the historic core of Aleppo, with about 30 percent of its buildings completely destroyed and huge amounts of debris generated. This paper proposes recovery strategies for some of the most badly damaged sites in the city through material reuse and transformation, one of the goals of which ...
Vocabulary in EFL teaching materials for young learners
Vocabulary is a key factor in successful language acquisition and as thetextbook is central in the teaching of English, ideas behind vocabularyinput in teaching materials should be based on research findings. Thepresent study is an analysis of seven teaching materials used for younglearners in Sweden. The results show that only a limited amount of ...
Mikrowellenpyrolyse von carbonfaserhaltigen Kunststoffen als Recyclingoption
Challenges in establishing a circular economy of carbon-fiber-reinforced plastics (CFRP) arise in particular from the necessary but problematic separation of the fiber from the matrix. The pyrolysis process is a possible technology for composite separation that has already been industrially implemented. A further development is microwave-assisted p...
Substitution modelling in life cycle assessment of municipal solid waste management.
Published in Waste management (New York, N.Y.)
Life cycle assessment (LCA) is gaining importance worldwide in guiding waste management policies. The capacity of co-products such as recycled materials and recovered energy to avoid primary production of equivalent products largely determines the environmental performance of waste treatment technologies. Estimating the reductions in resource use, ...
BIN-CT: Urban waste collection based on predicting the container fill level.
Published in Bio Systems
The fast demographic growth, together with the population concentration in cities and the increasing amount of daily waste, are factors that are pushing to the limit the ability of waste assimilation by Nature. Therefore, we need technological means to optimally manage of the waste collection process, which represents 70% of the operational cost in...
Recycling of Cerium and Lanthanum from Glass Polishing Sludge
Published in Polish Journal of Chemical Technology
To examine the efficiency of La and Ce recycling processes from the sludge, two major methods were used, namely leaching and precipitation. The findings suggest that 12% of La and 24.2% of Ce were contained in the sludge. The sludge was leached in an optimum condition of 6N HCl at a temperature of 70°C with a 3g/50 mL solid/liquid ratio for 3 h to ...
The impact of collection portfolio expansion on key performance indicators of the Dutch recycling system for Post-Consum...
Published in Waste management (New York, N.Y.)
The recycling network of post-consumer plastic packaging waste (PCPPW) was studied for the Netherlands in 2017 with material flow analysis (MFA) and data reconciliation techniques. In comparison to the previous MFA of the PCPPW recycling network in 2014, the predominant change is the expansion of the collection portfolio from only plastic packages ...
