Petru Rareş nr. 2We present a new ecological and economical alternative to landfill or incineration ofwastes, issued in the last years named mechano-thermal treatment. The procedure consists inmill mechanical processing, completed with sterilization due to high temperature produced byfriction heat released.So, many shortcomings, as infectious potential generated by the landfill storage orglobal warming and atmospheric pollution associated with incineration can be avoided. Byapplying this procedure the waste become environmentally safe product, compatible withnatural biotic cycle, unrecognizable (as odor and aspect) and can be used as fertilizers orcombustibles 1-3 .The application of the method means, essentially, in water evaporation, contractingvolume, lowering weight and thermal sterilization of the infected waste materials, due to hightemperature achieved by friction heat generated by mechanical crushing.In this paper, to prove the application and effectiveness of the procedure, we usedifferent raw materials (fish, meat, plant debris) and different work conditions, in a specialelaborated laboratory installation. We analyze the evolution of some significant parameters ofthe final processed products vs. raw waste: weight, density, caloric power and the microbialcontent.Experimental results show a very low humidity, doubling density, 40-50% weight loss, meancaloric power close to coal caloric power and complete sterilization. The characteristics ofthe final products demonstrate the possibility of successful application of this cheap and nonpollutanttechnique.1. Holliday M.G., Ford M., Burrell P., Gould F.K., Br. J.
