The work is devoted to the extremely urgent problem of public and industrial infrastructure dynamic development through the innovative recycling technologies design and implementation, which leads to significant material and energy resources savings. It should be noted that in the work, the authors expand the range of "recycling" concept application (reuse, renewal, processing of materials or structures elements) and give it a broader and more universal meaning, which in general covers a wide variety of current trends and different industry problems. 

The work in the completed view reflects the results of fundamental and unique research. In particular, the development, integrated research and implementation of new resource-saving and energy efficient recycling technologies – re-use of composite materials for construction and building structures repair, public and industrial infrastructure buildings and facilities, including road and airfield infrastructure objects, which are extremely relevant in the conditions of the President's national air transport capacity renewal program, as well as the search for ways to rationally solve strategic industrial problems by integrating new development of recycling technologies.

The work contains the theoretical and experimental investigations results, which generally indicate the developed recycling technologies efficiency. It is noteworthy that the main results are protected by low Ukrainian patents for utility model, as well as, which unambiguously indicates the uniqueness of the development, by a Ukrainian patent for a wine. Developed technologies advantages are proved on the basis of various buildings and structures variant design and complex comparative analysis of technical and economic characteristics (mass, labor intensity and production cost and installation, consumption and cost of materials, etc.).

Technical and economical indicators of composite materials designs developed with the suggested recycling technologies use were compared with the analogous characteristics of the common and widely spread solutions and structures designs. As a result, the efficiency of the suggested composite constructions was established in comparison with traditional solutions, which is reflected in lower materials and products consumption, in particular, steel, concrete, composites, cement, etc. On average, an efficiency of close to 30% is achieved in each case. This will result in a reduction of the project cost price, its competitiveness and economic efficiency.
