“…dust. The highest As concentration was found in wood (C3; 44.6 mg/kgTS) and originated likely from wood preservatives (Loferski, 1999). The overall highest Hg concentration was found in vacuum cleaner bags (C4; 160 μg/kgTS).…”

“…Additionally, humus presented significantly higher concentrations of Mo and V than all other organic fractions. The Sb content in animal bedding (Y6) (4.0 mg/kgTS) was three to 13 times higher than in the other organic fractions, probably due to wood preservatives as this fraction consisted mainly of wood chips which can origin from recycled wood (Dodoo et al, 2014;Loferski, 1999). Cat excrements (Y5) presented a significantly higher Al and Cs content than the other organic material fractions, which may be due to attached cat litter, which typically consists of aluminosilicate minerals like clay or zeolite (Jha and Hayashi, 2009).…”

Physico-chemical characterisation of material fractions in residual and source-segregated household waste in Denmark

Physico-chemical waste composition data are paramount for the assessment and planning of waste management systems. However, the applicability of data is limited by the regional, temporal and technical scope of waste characterisation studies. As Danish and European legislation aims for higher recycling rates evaluation of source-segregation and recycling chains gain importance. This paper provides a consistent up-to-date dataset for 74 physico-chemical parameters in 49 material fractions from residual and 24 material fractions from source-segregated Danish household waste. Significant differences in the physico-chemical properties of residual and source-segregated waste fractions were found for many parameters related to organic matter, but also for elements of environmental concern. Considerable differences in potentially toxic metal concentrations between the individual recyclable fractions within one material type were observed. This indicates that careful planning and performance evaluation of recycling schemes are important to ensure a high quality of collected recyclables. Rare earth elements (REE) were quantified in all waste fractions analysed, with the highest concentrations of REE found in fractions with high content of mineral raw materials, soil materials and dust. The observed REE concentrations represent the background concentration level in non-hazardous waste materials that may serve as a reference point for future investigations related to hazardous waste management. The detailed dataset provided here can be used for assessments of waste management solutions in Denmark and for the evaluation of the quality of recyclable materials in waste.

“…Froidevaux and Navi 13 and Kránitz et al 14 provided results showing that the physical and chemical properties of wood change due to the ageing and decay effect caused by the long-term effects of light, heat and humidity. Loferski 15 summarized the ageing effect of the wood structures of ancient buildings. However, the study of Froidevaux, Sonderegger and Loferski did not address the effects of ageing and decay on the fire performance of wood.…”

The degree of ageing, the combustion kinetic performance and the change law of the combustion characteristics of ancient pine were experimentally investigated using thermogravimetric analysis, calorimetry experiments, component analysis experiments and gas chromatography-mass spectrometry analysis. The results show that the hemicellulose, cellulose, lignin and resin contents of the ancient pine decreased by 4.78%, 3.87%, 1.39% and 0.63%, respectively. The volatile content of the ancient pine decreased by 7.37%, while the ash content increased by 5.02%. The terpenes in the ancient pine were almost decomposed, and the calorific value of the ancient pine decreased by 21.54%. The ignition point of ancient pine was 19.83°C lower than that of the fresh pine. The activation energy and heat of the pre-charring stage of the combustion of the ancient pine were 1.37 times and 0.51 times those of the fresh pine, respectively. In contrast, the activation energy and heat of the charring stage of the combustion of the ancient pine were 0.66 times and 1.2 times those of the fresh pine, respectively. The ignition time and peak time of the ancient pine were shorter, and the heat release rate, smoke production rate, specific extinction area and CO production rate were higher than those of fresh pine.

“…Also, it provides high thermal insulation and low electrical conductivity. In addition, samples obtained from hundreds of different species show different features and this situation can be seen even in the different parts of a tree (Loferski, 2001). Nevertheless, it can be damaged by factors such as moisture, the sunlight at different wavelengths, fire and organisms -409 - (Budakçı et al, 2016).…”

Non-destructive test techniques are becoming increasingly important for assessment and maintenance. These techniques are very useful for assessment of materials such as wood, whose performance can vary considerably depending on the conditions of use. It is possible to estimate some mechanical properties of a material by determining the movement of energy through the material with the help of these techniques. In this study, it was investigated whether the wood material could be tested nondestructively by the heat energy produced by a source. The correlations between the thermal conductivity and mechanical properties of Scots pine (Pinus sylvestris L.) and sessile oak (Quercus petraea L.) woods were investigated. The thermal conductivity (TC), density, modulus of rupture (MOR), compression strength (CS), and modulus of elasticity (MOE) values of samples were measured according to the related standards and these values were correlated with each other. The linear and multiple regression tests were employed to determine the correlation between thermal conductivity and mechanical properties. The results showed that there is a very strong correlation between thermal conductivity and both density and MOR values. However, the correlations between TC and both MOE and CS were moderate. The results of this study suggest that the thermal conductivity value can be used to estimate the density and some mechanical properties of wood.
