ABSTRACT:
The invention manufactures mechanical strong objects from a mixture of a plurality of fractions, which together have a high filling grade by accommodating them in plastic, preferably a thermosetter of the low viscosity type. The plastic is preferably resistant against leaching as defined in the Concept Bouwstoffenbesluit, when pollutions in the fractions are present. Finally the invention gives objects with good mechanical properties at low cost price, because of the relatively small use of plastic (to only 8 volume % or less) and the favorable mechanical properties of strongly densified waste, residual or filler materials. Coloring of the objects is possible and the surface can be very smooth. Fibres or residues of fibres containing waste materials can improve the obtained products still further.
