PCT No. PCT/FI95/00383 Sec. 371 Date Jan. 21, 1997 Sec. 102(e) Date Jan. 21, 1997 PCT Filed Jul. 3, 1995 PCT Pub. No. WO96/02590 PCT Pub. Date Feb. 1, 1996Waste plastic material is treated so as to make possible its utilization as a binder component in road surfacing materials, as a fuel, or for other desirable purposes. The waste plastic material is made at least partially fluid by mixing it with a solvent. The solvent is waste fats produced in refining or by treating animal and/or vegetable fats, crude fatty acids obtained as byproducts of refining fats, or fatty acids or pitch obtained by distilling hydrolyzed fats. The solvent is typically mixed with waste plastic material in the ratio of less than 1:2, preferably about 1:3, and at a temperature of between about 150 DEG -250 DEG C.
