Immobilization of Electric Arc Furnace dust toxic elements within the matrix of concrete based products


Sikalidis C., Mitrakas M. and Tsitouridou R.


Electric Arc Furnace Dust (EAFD) generated through the production of carbon and alloy steel products is classified as environmentally hazardous waste mainly because of its relatively high levels of Pb, Cd and Cr. The aim of the present work was to investigate the effect of the EAFD addition on the...

Modification of the mechanical properties of rubbers by introducing recycled rubber into the original mixture


Varga CS. , Miskolczi N., Bartha L. and Palot?s L.


In our experimental work the opportunities of improving of mechanical properties of rubbers and their composites have been investigated. On the one hand the reuse of milling product of recycled rubbers (recycled crumb rubbers) has been studied and the effects of the filler and compatibilizers...

Estimation of microclimatic data in remote mountainous areas using an artificial neural network model-based approach


Chronopoulos K.I.,. Tsiros I.X, Alvertos N. And. Dimopoulos I.F


An artificial neural network (ANN) model-based approach was developed and applied to estimate values of air temperature and relative humidity in remote mountainous areas. The application site was the mountainous area of the Samaria National Forest canyon (Greece). Seven meteorological stations were...

Analysis of the evolution in current biomass to energy strategies, policy and regulations in Spain


San Miguel G., Servert J. and Canoira L.


Global warming is one of the most serious challenges facing humankind as it has the potential to dramatically modify the living conditions of future generations. In order to reduce the emission of greenhouse gases, most countries are implementing regulations aimed at reducing their dependence on...

A comparative study of human thermal comfort conditions in two mountainous regions in Greece during summer


Kamoutsis A., Matsoukis A., Chronopoulos K. and Manoli E.


Human thermal comfort conditions were determined in two mountainous regions of Greece, Gerania mountains (MG) in east continental Greece, and mountainous Nafpaktia (MN) in west continental Greece. Both regions are unexploited with considerable tourist potential. Four sites in each study region were...

Discarded tyre rubber as concrete aggregate: a possible outlet for used tyres


Mavroulidou A. and Figueiredo J.


Discarded vehicle tyres constitute one important part of solid waste which had historically been disposed of into landfills. Recent EU policies on the Landfilling of Waste (Council Directive 1999/31/EC) have however put a ban on the landfilling of whole or shredded tyres, creating an imminent need...

Evaluation of postfire restoration in peri-urban forest of Thessaloniki, Northern Greece


Spanos I.A., Ganatsas P.P. and Tsakaldimi M.N.


Postfire plantation results and pattern of natural revegetation process were monitored for six years after wildfire in the artificial Pinus brutia forest of the suburban park of Thessaloniki, northern Greece. Some flood-preventing treatments and plantings took place on half of the burned area...

Decentralized aerobic composting of urban solid wastes: Some lessons learned from Asian-EU cooperative research


Karagiannidis A., Theodoseli M., Malamakis A., Bilitewski B., Reichenbach J., Nguyen T., Galang A. a... View all


Composting of organic solid wastes is gaining in importance worldwide, in the frame of integrated municipal solid waste management and, in particular, the diversion of biodegradables from landfilling. At the post-consumer stage, this can be achieved by composting practices ranging from large-scale...
