Abstract: The present invention provides an integral system for recycling post consumer motor-oil plastic containers. Oils and especially motor-oil, physically attaches to its HDPE (high density polyethylene) containers demanding a unique recycling process. As described by this patent, oil-contaminated plastic containers are thermally drained and mechanically freed from their labels and aluminum sealing rings. Unlabeled containers are further shredded through oil-free flake-cutting process, in which, plastic melting is minimized, thus preventing oil to be trapped inside the plastic structure. A hot water bath of sulfonic acid and/or detergents, containing the shredded flakes, is subjected to a very high turbulence in the absence of air (water sealed), which induces liquid cavitation.
