Cements to replace ordinary portland cement (OPC) are currently being studied due the high environmental costs of OPC production. One viable alternative is alkali-activated cements, which can be made from pozzolanic materials such as stone wool fiber waste (SW). At present, SW most used insulation material in world, and disposal recycling it an challenge its fibrous nature low density. In prese...

The inevitable depletion of mineral resources, the constant deterioration of the geological and mining conditions for the development of mineral deposits and the restoration of raw materials from mining waste by recycling are all urgent problems we face today. The solution to this problem may ensure: a considerable extension of raw material source; decrease of investments in opening new deposit...

In this study the effects of different levels of industrial wastes on growth traits and metal accumulation in aerial portions were determined for Populusxeuramericana clone I-214. The experiment started in April 2003. Scions of Populusxeuramericana clone I-214, were grown outdoor near Pisa (Italy), in lisimeters filled with soil naturally present in the land around the experimental site, were d...

This study examined the efficiency of different organic waste materials as NPK fertilizer, in addition to the risk for leaching losses related to shower precipitation in the first part of the growing season. The experiment was tested in a pot trial on a sandy soil in a greenhouse. Six organic fertilizers were evaluated: liquid anaerobic digestate (LAD) sourced from separated household waste, ni...
