Over 3000 million tons of waste management are generated annually, out of which 25%-30% are Construction and Demolition Waste (CDW). Construction and Demolition Waste (CDW) is generating major issues regarding logistics, provision, and environmental impact. The European Commission, by its Waste Framework Directive, is requesting to increase the recycling rate of the weight by 2020. Since actual material separation techniques require manual quality control and sorting, which is dangerous because workers suffer from...

Recycling of asphalt is an important technological process applied worldwide. The strategy is to use as much milled, ripped or broke asphalt material into the new mixture. With the correct technological design, the maximum appreciation of this material is achieved. Due to the dominant use of asphalt mixtures in pavements, it is important to address the possibilities of their recycling. At present, a sufficient amount of reclaimed asphalt with good potential for further use is available in Slovakia. The problem is ...

The present study has been dedicated on the removal process of heavy metal ions from electrolyte solutions by using methods of electroflotation and subsequent filtration in a multi-component system with the presence of various surfactants of different nature. The research was conducted in a five-component system comprising ions of iron (II), nickel (II), copper (II), plumbum (II), and zinc (II) (the total concentration of metal ions is 200 mg/l). The research was conducted in a highly concentrated electrolyte solu...

Taking into consideration limited financing of waste processing industry in Russia, refuse derived fuel production is becoming a promising course to decrease MSW landfilling at minimum cost, as the method allows safe energy recovery in existing cement kilns and precalciners. For its part, the cement industry pursues a lower level of fuel expenditure, which accounts for about 20% of total production cost. In this regard, fossil fuel substitution for fuel from waste is a mutually beneficial solution, linking the int...

Waste disposal and management is one of the urgent issues faced by mankind at the current stage of development. Waste car tires pose a significant threat to the environment, which makes their efficient processing particularly important, as the volume of this type of waste generated each year worldwide is estimated at more than 10 million tons, of which 1 million tons are produced in Russia. A review of the car tire, wood, textile, and plastic pyrolysis products is presented. The products of pyrolysis include pyrol...
