Both steps of pyrolysis were catalyzed by Portland cement. However, prior to second step of pyrolysis, the pyrolysate of each sample was separated into volatile combustible liquid and a paste like organic material. The organic paste was used as feedstock for second step of pyrolysis and converted into oil and highly combustible gas.

The new batch pyrolysis plant in Studsvik is built primarily for treatment of uranium containing dry active waste, 'DAW'. Several other waste types have been identified that are considered or assumed suitable for treatment in the pyrolysis plant because of the possibility to carefully control the atmosphere and temperature of the thermal treatment.
Both steps of pyrolysis were catalyzed by Portland cement. However, prior to second step of pyrolysis, the pyrolysate of each sample was separated into volatile combustible liquid and a paste like organic material.
