1.  The Invention


Title                             Recycling MaterialS from Hard PU AND LWC

The problem the inventor(s) wanted to solve

Inventor propose a model of recycling isolating materials, made of hard polyurethane and lightweight concrete, with aggregates containing expanded glass. The scope of the aforementioned model is to plan production processes without waste.



Use of recycling construction and isolation materials in civil construction present one of the very important method for efficient sustainable use of materials and energy. Results indicate characteristics of density, compressive strength and thermal conductivity   are changing in dependency of the type and part of waste as well as the type and part of fresh binding components.



A new binary composite is created with new characteristics of density, compressive strength and thermal conductivity, which is conformed with Rules on heat protection and energy efficiency use in buildings and  can be used for heat protection and efficient  use of energy in buildings.

Fields of application

Construction, energy efficiency.



Method shows great possibilities for increasing use of construction waste isolating materials from hard polyurethane and lightweight concrete with aggregates containing expanded glass in order to benefit from better use of available capacity of existing construction waste.


Stage of development. Pre-production.
