Analysis and interpretation of the leaching behaviour of waste thermal treatment bottom ash by batch and column tests
Autor: Giulia Costa, Martina Di Gianfilippo, R Gavasci, Francesco Lombardi, Iason Verginelli
Publikováno v: Waste Management. 56:216-228
This paper investigates the leaching behaviour of specific types of waste thermal treatment bottom ash (BA) as a function of both pH and the liquid-to-solid ratio (L/S). Specifically, column percolation tests and different types of batch tests (inclu

Publikováno v: Journal of Contaminant Hydrology. 183:99-108
In Situ Chemical Oxidation (ISCO) based on the Fenton's process is a proven technology for the treatment of groundwater contaminated by organic compounds. Nevertheless, the application of this treatment process to methyl tert-butyl ether (MtBE) is qu

Quality evaluation and improvement of mechanically–biologically treated municipal solid waste in view of a possible recovery
Autor: R Gavasci, M Di Lonardo, Francesco Lombardi
Publikováno v: International Journal of Environmental Science and Technology. 12:3243-3254
This study aimed to identify possibilities to improve the quality of the stabilized biowaste coming from the mechanical–biological treatment of municipal solid waste produced in Rome for possible recovery rather than landfilling. The waste sampled
