Obiettivo Objectives and content The objective of this industrial research project is to develop low cost 'by-product' fillers as a replacement for high cost "primary" fillers, in a range of industrial products where neither the production specification nor the end use demands a high-grade filler product. The source of the 'by-product' fillers will be the mineral residues of crushed rock aggregate quarries. The residues from two major rock types (siliceous and calcareous) will be assessed and will be upgraded by a novel particle size-reduction process and by the application of suitable beneficiation techniques. Mineral fillers are used in a wide range of commodities and are fine grained materials (<2mm) which are mined specifically for that purpose ('primary' fillers) e.g. kaolin and calcium carbonate. Primary sources are used because applications such as communications paper and household paints require a mineral, which has a high brightness level and good rheological properties. Such fillers are marketed at a relatively high cost, as the total production costs, i.e. extraction and processing, have to be recovered by the operator. However, many applications such as packaging paper, marine paint, plastics, membranes, ceramics, tires and electrical cables, as well as a number of construction materials such as asphalt, porous concrete and lightweight concrete blocks do not require fillers of such a high grade. The aim of this project is to develop 'by-product' mineral fillers for these markets. During the production of crushed rock aggregates large volumes of mineral residue (10% to 25% of total output) are generated, much of which is fine-grained and generally creates problems to the environment. This potentially valuable resource is substantially unused and it is essential that optimum use is made of these residues to meet sustainability criteria and improve the profitability of quarry operations throughout the EU, whilst creating added value products. This project will concentrate on the production of lowcost 'by-product' fillers from these fine mineral residues, as a cheaper alternative to the high-cost primary' fillers. The products, which will be investigated, are industrial paints, low-grade paper, asphalt and lightweight concrete blocks. The project includes 2 quarry operators (representing the two major quarried rocks types - siliceous and calcareous), 3 end users (industrial paint; packaging and toilet paper; asphalt, and lightweight concrete blocks), 1 equipment supplier (novel grinding equipment) and 3 research organisations. Four of the industrial partners are SMEs. Emphasis will be placed on the marketing aspects and a marketing Consultant will be retained for the duration of the project. The Tasks will be as follows: Task 1 Field/Sampling Studies Task 3 Laboratory Scale Tests Task 5 Product Development Task 7 Marketing Study Task 9 Techno-economic EvaluationTask 2 Residue Evaluation Task 4 Large Scale Continuous Tests Task 6 Evaluation of Products Task 8 Re-evaluation of Quarry Practices The economics are highly favourable and it has been estimated that the production of around 400,000 tons per annum of 'by-product' filler would generate ECU 32 million/annum for the quarry operators and provide a saving of over ECU 10 million/annum for the user industries. These are conservative figures as they represent, within the EU, only 0.5% of the residues produced each year and only a 2.7% replacement of the 'primary' filler market. The Producers will need to increase the number of employees and the users should be able to maintain employment at the present level. The partners in this project would wish to participate in the Thematic Network - "TRAWMAR". The Brite-Euram m areas covered by the proposal are 1.3.2.L 1.3.3.M and 1.3.1.S.
