Refuse-Derived Fuels (RDFs) are segregated forms of wastes obtained by a combined mechanical-biological processing of municipal solid wastes (MSWs). The narrower characteristics, e.g.

Lipidic carriers are efficient vehicles preserving drugs during cell administration. Several production processes of lipidic nanoparticles were developed to reduce mean size at nanometric level, enhancing homogeneity and process replicability. However, lipidic aggregation has always been considered a huge drawback in terms of high polidispersity and instability.

Sludges differed in that they had been conditioned - at the flocculation stage of wastewater treatment - either with Ca-based inorganics or with polyelectrolytes. Combustion was efficient for both sewage sludges under all the operating conditions tested.

In order to reach the irreducible saturation the experiments have been run with sweeping water velocities outside the range of validity of the Darcy's law. The size of the glass beads was varied in the range between 2 mm and 5 mm.

The gelling reaction has been carried out using as crosslinking agents either Cr(III) or Al(III) cations. By using Cr(III) the gelation time, which has been measured for a range of xanthan and/or Cr(III) concentrations, is of the order of the hour.
