The paper presents the results of design and research work aimed at producing ultracomposite lightweight aggregate (UCLA) as a result of combining waste from different sources. The developed production technology allowed to utilize waste from thermoplastic polymers (PET) with mineral waste from combustion processes, and to produce a lightweight aggregate that can be widely used in construction. During the development of the technology to produce a new, ecological aggregate, the physical properties of thermoplastics and their high viscosity in the molten state were used. As a result of a properly conducted thermal treatment in specially designed conditions, a composite in the form of granules corresponding to an aggregate fraction of 2 – 8 mm was produced. Different types of lightweight aggregates made with various fine-grained mineral fillers – by-products of combustion – were obtained, the basic properties of which were studied and presented.
