“…3. Interestingly, when oxygen is present the first step of the degradation of the polymer fraction ends at a slightly higher mass fraction (around 0.60, compared to 0.55 in pyrolysis) but no shift to lower temperatures is observed as occurred with PVC [11]. Furthermore, the second step is delayed from 450 8C on, and finally the char residue totally disappears.…”

“…From Figure 3 it is clear that the presence of oxygen accelerates the thermal decomposition of SRF, as it occurs with other materials [11][12][13][14], producing the decomposition at lower temperatures. Figure 1 represents the pyrolytic decomposition of the SRF.…”

The thermal decomposition of a Solid Recovered Fuel (SRF) has been studied using thermogravimetry, in order to get information about the main steps in the decomposition of such material. The study comprises two different atmospheres: inert and oxidative. The kinetics of decomposition is determined at three different heating rates using the same kinetic constants and model for both atmospheres at all the heating rates simultaneously. A good correlation of the TG data is obtained using three n th order parallel reactions.

The constant increase in the production of electronic devices implies the need for an appropriate management of a growing number of waste electrical and electronic equipment.Thermal treatments represent an interesting alternative to recycle this kind of waste, but particular attention has to be paid to the potential emissions of toxic by-products. In this study, the emissions from thermal degradation of printed circuit boards (with and without metals) have been studied using a laboratory scale reactor, under oxidizing and inert atmosphere at 600 and 850 ºC. Apart from carbon oxides, HBr was the main decomposition product, followed by high amounts of methane, ethylene, propylene, phenol and benzene. The maximum formation of PAHs was found in pyrolysis at 850 ºC, naphthalene being the most abundant. High levels of 2-, *Corresponding author. E-mail: ja.conesa@ua.es.

Emissions of PCDD/Fs and dioxin-like PCBs were quite low and much lower than that of PBDD/Fs, due to the higher bromine content of the samples. Combustion at 600 ºC was the run with the highest PBDD/F formation: the total content of eleven 2,3,7,8-substituted congeners (tetra-through heptaBDD/Fs) was 7240 and 3250 ng WHO 2005 -TEQ/kg sample, corresponding to the sample with and without metals, respectively.
