The transitions and reactions involved in the thermal processing of binary mixtures of polyethylene and poly(ethylene-co-vinyl acetate) copolymers with different concentrations of a foaming agent (azodicarbonamide) were studied using differential scanning calorimetry (DSC). The effect of ZnO as a kicker…

A study of seawater intrusion under controlled laboratory conditions using multicomponent heterovalent chromatography is presented. The aim was to understand the influence of several variables on hydrogeochemical transport, especially on gypsum precipitation and cationic exchange. In addition, the study aimed…

The use of numerical values for the chemical components of waters from an aquifer as input data for factor analysis is shown to be sometimes more convenient than the use of the logarithms of these figures. Factor analysis was applied…

The different transitions and reactions involved in the thermal processing of ternary EVA-PE-ADC mixtures, with different concentrations of polyethylene (PE) and azodicarbonamide (ADC), used as foaming agent, have been studied by means of differential scanning calorimetry (DSC).
The effect of…

A comparison between different emission rates of various pollutants obtained from various wastes is presented. The studied wastes were the following: polyethylene (PE), tyres, sewage sludges, polyvinyl chloride (PVC), cotton textiles, polyester textiles, meat and bone meals (MBMs), varnish wastes,…

The thermal degradation of samples of used cotton fabrics has been investigated using thermogravimetric analysis (TGA) between room
temperature and 700 °C. Experiments were carried out with about 5 mg of sample in three different atmospheres: helium, 20% oxygen in…

This paper studies the effect of two different parameters on the different fractions obtained in the catalytic pyrolysis of HDPE using HZSM-5. On one hand, the influence of the heating rate on the results obtained has been studied by selecting…

The decreasing costs and increasing availability of electronic products of all kinds, including mobile phones, audio and video equipment, and personal computers and their accessories, coupled with advances in technology that rapidly make these products obsolete, foretell a growing disposal…

A wide kinetic study has been carried out under different conditions in TG and TG–MS for each material, at different operating conditions. Runs were carried out at three different atmospheres: N2, N2:O2 4:1 and N2:O2 9:1. In addition to the…
