Technical features

A process for the recovery of titanium dioxide from waste paper containing iron, after forming sheets of decorative paper, comprises using an aqueous non-oxidising mineral acid. The liquid extraction agent phase is separated and the organic residue is oxidised pyrolytically to form CO2. Extraction takes place at a temperature above 50 °C, especially above 75 °C, at the boiling point of the acid. The non-oxidising mineral acid is hydrochloric acid. Oxidation takes place at 500-850°C. After the residue is removed, the extraction agent is treated to recover the acid. The waste paper contains an impregnated resin, and is boiled with a strong base. The extraction takes place in a reactor.

Die Avalanche-Methode

Zur Identifikation von Entwicklungs- und Vertriebspartnern oder Lizenznehmern bedienen wir uns eines einzigartigen Ansatzes. Wir nennen ihn „avalanche“ – die Lawine.

Kurz gesagt ist die Lawine eine selbst-organisierende, webbasierte Umfrage in der jeweiligen technischen Community. Auf diese Weise gelingt es uns in kurzer Zeit, einerseits relevante Informationen über Ihre Innovation und deren wirtschaftliche Perspektiven zu gewinnen und andererseits Ihre Idee einer Vielzahl möglicher Partner zur Kenntnis zu bringen.
