Recycling and upgrading of bone meal for environmentally friendly crop protection and nutrition

Exploitable results

The IPR-protected PROTECTOR zero emission process upgrades the food industrial and agricultural by-products into high added value and safe biological crop protection, plant growth promotion and natural fertilization products for environmentally friendly horticultural soil and soil-less cultivation. Hog origin animal bone meal is left over from the food industry which, after thermal treatment up to 850 ºC (carbonization), contains high concentrations of contamination free P and Ca minerals. The porous structure of bone char offers to the microbes a protected niche when introduced into soil. This product, therefore (called 'animal bone char' or 'ABC'), can be used as a carrier for biological control agents or other beneficial microorganisms, whilst delivering P and Ca for plant growth. Terra Humana Ltd. is one of the leading international companies in the area of carbonization, solid state fermentation and formulation science and technology; it provides an original source of combined scientific knowledge and industrial engineering base. The specific bone char thermal treatment technology developed and designed by Edward Someus is the only one known on the international market which can produce the bio specific bone char solid carrier. The integrated bone char and biotech processing technology is also the only one known on the international market with specific performance. The production and use of animal bone charcoal for biotechnological solid carrier is a highly innovative carbonization method and product. The PROTECTOR is the only known technology system, where solid carrier thermal treatment and biotechnological systems are built together. As Animal Bone Charcoal (ABC) carrier development and Solid Substrate Fermentation and Formulation (SSFF) technology innovative developments run in parallel, a coherent link has been structured between the two tasks. Therefore, the production of such innovative solid carrier or carriers requires advanced knowledge, special care and considerations, in depth scientific and technical understanding and tests. During the PROTECTOR applied scientific RTD programme prime and second best natural soil microbial strains compatible with Animal Bone Charcoal for (1) mobilization of the phosphorus mineral content of the ABC carrier for plant uptake and (2) positive biocontrol effect have been successfully selected. Innovative Solid Substrate Fermentation and Formulation (SSFF) technology has been developed and optimized. During the applied scientific RTD and application oriented optimization, the PROTECTOR products have been successfully multiple tested for several years under different climatic, soil and agro-industrial true value production conditions in Hungary, Israel, Italy, Germany and The Netherlands. The EU relevant permitting field tests have been completed at the end of 2008.The results have clearly indicated the positive PROTECTOR efficiency under different field condition. The PROTECTOR open ecological field Application Permit has been received in 2009.
