3-Activity on prototype 1

 

One hundreds eight (108) pellets made of waste and reagents were moulded, pressed and previously characterized by SEM-EDS and XRPD. For each type of waste, several pellets were piled up to test the propagation of the combustion.

The combustion was ignited with the W coil ( https://www.facebook.com/video.php?v=1477981719136053&set=vb.1477802025820689&type=2&theater), or with an oxyacetylene torch

(https://www.facebook.com/video.php?v=1480086798925545&set=vb.1477802025820689&type=2&theater).

 

 

The SHS combustion was applied satisfactorily to :

  1. Friable fibres

  2. Linoleum

  3. Fibre-cement

 

After the SHS combustion the pellet towers were analyzed by SEM and XRD. In figure 1 is reported the SEM image of friable fibres before the SHS treatment.

The end products (Figure 2) are granular silicates and oxides, (e.g. granular forsterite), reusable as abrasive, refractory or ceramic second raw material, or, at worst as aggregates.
