Abstract: The present invention relates to a method for removing ink and/or a foreign material different from ink from the surface of an article, wherein at least a part of the surface of the article comprises a polymer selected from the group consisting of polyolefins, polystyrene, melamine polymers, polyvinyl chloride, polyethylene terephthalate, polyamides and mixtures thereof, the method comprises the following steps: i) providing an ink imprinted article and/or an article having a surface covered at least partly by a foreign material different from ink; ii) contacting the article provided in step i) with an acid having a pKa in the range from -10 to 7 having a minimum concentration of 1 wt.-% for solving the ink and/or the foreign material different from ink or their degradation products in the acid; iii) separating the acid and the therein dissolved ink- and/or foreign material different from ink or their degradation products from the article to obtain a deinked article and/or an article with a surface free from foreign material. Furthermore, the present invention refers to the use of the method for the recycling of polymers.

Abstract: The present invention relates to a method for removing a foreign material from the surface of an article comprising the following steps: i) providing an article having a surface covered at least partly with a foreign material; ii) contacting the article provided in step i) with a cleaning medium being an acid having a pKa in the range from -10 to 7 having a minimum concentration of 1 wt.-% and with a carrier medium having a density different from the density of the cleaning medium to obtain a mixture comprising the foreign material solved and/or dispersed in the cleaning medium, the carrier medium and the article free from the foreign material; iii) allowing the mixture obtained in step ii) to separate to obtain a heterophasic emulsion comprising at least a first phase comprising the carrier medium and the article free from the foreign material and a second phase comprising the cleaning medium and the foreign material solved and/or dispersed therein; iv) separating the phases obtained in step iii); and v) separating the article free from the foreign material from the carrier medium. Furthermore, the present invention relates to an installation for carrying out the inventive process.
