The main feature of modern methods of waste processing is their one-cycle nature. TheRoman Club «Comе on» jubilee report of the analysts, in 2018 stresses that, despite the development of engineering in the field of waste processing, theamount of wastes in the world is not decreasing, even in the developed countries such as the USA, Sweden, Germany and the United Kingdom, where waste processing is effectively handled. Burning the wastes that can be burnt still remains the most radical way of getting rid of them while gettingash as another kind of waste. Other wastes, one way or another, are ultimately not processed. In particular, this refers to pre-structured in materials post-operational waste. One of the ways out is the creation of technologies for multi-cycle processing of such wastes, which becomes an important factor in saving natural resources. The main limitation in such technologies can be the integral entropy of each subsequent method of processing such wastes. It is the criterion that reflects the ability to receive from a particular waste some ready products at asucceeding stage of its processing. It has been shown that each subsequent stage of post-exploitation waste processing may become the last one if the total expenditure ofa certain quality energy does not result in a new commodity product with useful qualities. Environmental engineering has only some of such multi-cycle processing technologies at its disposal. However, it is possible to systematically combine separate technologies that, in the form of a single technological cluster, will make it possible to consistently change the state of each post-operational waste, bringing it to the state of a ready product
