Abstract :This thesis discusses the implementation of a new way of urban waste management in terms of its non-aggressive and productive destination, at low energy costs and with high reuse of byproducts. It is based on scientific foundations established by thermodynamics, classical field theory and empirical disciplines that deal with properties of chemical elements and with technologies of calorific capture from remote sources. Aiming at the transformation of any form of condensed matter, it is primarily interested in the so-called infectious waste, because they have greater virulence, infectivity and concentration, and wastes of type "skin-scissoring-piercing", which are objects and instruments containing corners, edges or rigid and acute protuberances capable of cutting or drilling. Nevertheless, the model also applies to all types of waste, with the exception of radioactive waste for obvious safety reasons. Present work proposes an industrial system to recycling waste based on pyrolysis induced by plasma and guided by the proposed theory of caloric fields under controlled entropy.
