Abstract
A method for separation of heterogeneous products included in household waste (HW) comprises separating the products in a fractionation vessel containing a liquid. The waste includes components, of which at least some are capable of floating in the liquid. The components are exposed to a first essentially horizontal force (P) in a first direction (D) enforced by a flow of the liquid in the fractionation vessel and to a second essentially horizontal force (P) in a second direction (D), which is substantially different from the first direction (D). The combined impact of the forces (P; P) on the components spreads the components and leads them to at least two collection areas. Products of varying buoyancy may thus be treated separately.
