The work presents a new approach to the copolymerization and co-processing of industrial organochlorine waste (OCW) resulted in the production of vinyl chloride at Karpatnaftochim LLC, Kalush, Ukraine, and liquid wood pyrolysis products (LWPP) generated by the activated charcoal production at Perechyn Forestry and Chemical Plant, LLC. Kalush, Ukraine. This article highlights studies of the composition of the raw materials and the properties of the resulting products.

The beginnings of warm mix asphalt are connected with the use of foamed asphalt in the ‘60s of the last century. Asphalt foaming occurs by contact with water or water steam that can be entered mechanically or under pressure. The foaming effect can be also obtained by the adding of zeolite to the asphalt mixture which causes the lower viscosity of the asphalt, better workability and adhesiveness of the mixture to the aggregate in lower temperatures. Presently, synthetic zeolites Aspha-Min and Advera are used for reducing the processing temperature.
