Project summary

One of the most significant problems of modern civilization is purification of environment from solid household and industrial waste, in particular, utilization of polyethileneterephthalate (PET) unfit to natural decomposition [1].

The subject of this project is development of the prospective way of solving this problem i.e. methods of utilization of certain kinds of solid industrial and household waste, in particular, PET, dusty ashes of thermoelectric power stations (TEPS), gravel production waste, various industrial slags, wood sawdust and other waste materials with manufacturing on this base novel composite materials with advanced consumer characteristics. The offered family of composite materials on the base PET matrix (PETMC) consist of PET with function of binding matrix and one or several filling materials from the list of mentioned above solid waste materials [2]. The latter ones determine significantly basic mechanical, electrical, physical-chemical and other functional properties of PETMC.

The most significant feature of this project is utilization of not the primary PET but the secondary one. It is used in the form of fine-milled used articles made of PET (bottles, glasses and so on) or PET-articles production waste. Extermination of such waste is now one of the most significant problems of environment protection since natural decomposition of PET is impossible and utilization of this material for any purpose does not have yet any principal solution. PETMC solves this problem.

The novel materials of PETMC family are produced by mixing of mentioned above components followed by heating and compaction of the mixture in the mould under elevated temperature and high enough pressure [3,8,9,10]. It results in manufacturing various purpose goods The goods of PETMC obtained by this method have high strength and hardness (at the level of soft steel or copper), high wear resistance, very low water absorption, low thermal and electric conductivity. With respect to this combination of properties, such materials seem to be very prospective for producing wares for building industry [4,5,6,7], mechanical engineering, electrical and some other fields of industry.

The essential feature of PETMC materials is its extreme cheapness because the components making them are household and industrial waste [11]. That is why, the offered project opens new outlooks in solving the problem of both utilization of solid waste and development of resource-saving technologies.

Functional properties of PETMCs are forming in dependence on their breakup, temperature and pressure of their pressurizing. These dependencies are the subject of detailed studies being the main content of this project.

Scientists and specialists that represent participant institutions in the project have long-term experience in creation of new composite materials of various composition and destination. Their works is well known in Russia and abroad. It proves high scientific level of project executives’ team and vouches for its successful realization.
