Objective Objectives and content World-wide, 600.000 tonnes of acid activated clays are produced annually. 60 % of these are consumed in the food industry, for refining of edible oils and fats, (bleaching earth), while the rest are used in various other industries, like mineral oil industry, chemical industry and in environmental applications. For the production of activated clays high quality bentonite raw materials are treated with inorganic acids, like HCl or H2SO4. The most important problems related to the production of activated clays are (a) the use of inorganic acids, causing serious environmental problems, due to the residual acidity and the metal cations contained in the effluents (b) the selection of special quality and expensive appropriate raw materials, as not all types of bentonite are amenable to acid activation. In order to eliminate the disadvantages of the current industrial practice the application of an innovative technology based on the treatment of natural acid clays and bentonites by organic acids is proposed to be examined. The industrial objectives of the proposal are: to develop an innovative, cost effective and environmentally friendly technology for the treatment of natural acid clays and bentonites by organic acids. to produce high surface area materials from natural acid clays and bentonites of similar or superior quality to those produced by the inorganic acid treatment. to exploit the natural acid clay deposits found in various parts of Europe which have remained so far unexploited. to study the amenability of low quality bentonites to organic acid activation. The expected achievements are: enhancing the competitive position of the European companies in a 240 MECU market, exploitation of mineral resources in the EU, development of an environmentally friendly mineral processing technology for the long term protection of the ecosystem and the health of the human population. The generic nature of the project will allow application of the results to a wide number of natural acid clay and bentonite deposits. As case studies, samples from representative deposits in Greece, Italy and Germany will be processed. The project consortium is highly complementary as it comprises three of the most important bentonite and clay producers in Europe and world-wide, three of the biggest acid activated clays consumers in Europe (end-users), one academic institute highly experienced in industrial mineral processing and effluent treatment and one research institute expert in the physicochemical characterisations of the products involved. The proposed project is highly consistent with the European materials research work programme. An advanced process with low environmental impact and at lower cost will be developed to produce high quality industrial products for existing and new applications.
