The Process-Advantages

The previously described FAR technology demonstrates that it is possible to transform ash, of different types and constituency, into a valuable building material with attractive economical and, no less important, ecological advantages.

The most attractive aspect of the process is the possibility to mix ash with different industrial waste materials utilising the inerting effect of the base-matrix (the ash).

A practical example is represented by the backfilling of mines. During the processing of the basic material, mine waste and water can be added. The complex structure, insoluble in water after hardening, fulfills the necessary quality requirements of the backfilling.

In addition it is possible to solve specific and expensive waste problems. The process developed for this application reduces costs by more than fifty per cent.

Also the "normal" basic product, which can be mixed with hardcore from demolished buildings etc., offers new marketing opportunities due to it's suitability for road building projects.

The foundation of the process is a controlled treatment system developed over long years of research. At the heart of this technology is the temperature control of different exothermic processes by means of specially developed interactive elements. The specific characteristic of the process offers the possibility of avoiding the co-mon, however quite complicated, measurment of chemical influencing factors (e. g. the effect of free-lime content).

The treated ash, after a process of about 50 minutes only, is ready for transportation and for storage in silos. The product can be subjected at any time subsequently to a final variable treatment, depending upon the proposed usage of the product.
