According to global market analysis, annual production of polymer composites is expected increase by an average 6%, reaching a volume 13-14 million tonnes 2024, primarily in the building industry and mechanical engineering sectors. Recycling can be achieved through secondary use or recycling solid waste. In Russia, about 160 out 343 producers are engaged recycling, with focus on thermoplastics....

Recently in Thailand, the recycling process of waste printed circuit board (WPCB) has retained a large volume of nonmetallic fraction (NMF), which has entered the industrial waste stream and awaits an appropriate treatment to be suggested. The aim of this paper was to assess environmental impacts of the recycled nonmetallic fraction from waste printed circuit board in Thailand, using the ReCiPe...

Purpose – The purpose of this paper is to focus on optimization of recycling of concrete from lightweight aggregates containing expanded glass and hard polyurethane (PU) and on the issue of importance of environmental management in constructions, to produce the new combination using rest, construction waste of concrete from lightweight aggregates and hard PU new raw components of concrete from ...

Spray-drying, which has been used for commercial production of functional ingredients from several fruits and vegetables, has not yet been studied for sweetpotato processing. Thus, the objective was to determine the effects of viscosity reduction of sweetpotato puree with alpha-amylase, maltodextrin (MD) addition, and inlet air temperature on the physicochemical characteristics of spray-dried s...

In view of the ever depletion sources construction materials, there is a need to explore feasibility using palm kernel shells and glass as replacements for natural crushed aggregates in Portland cement concrete. Concrete specimens produced with 25% partial replacement coarse aggregate varying percentages recycled powder pozzolana were tested their workability, compressive strength, tensile stre...

Ceramics and glass ceramics based on industrial waste have been widely recognized as competitive products for building applications; however, there is a great potential for such materials with novel functionalities. In this paper, we discuss the development of magnetic sintered glass ceramics based on two iron-rich slags, coming from non-ferrous metallurgy and recycled borosilicate glass. The s...

Portugal, with 210,422 tonnes of glass recycled in 2011, did not attain the target for glass (227,060 tonnes), and this happened probably due to three factors: the reuse of this material since glass is a durable material, non-declaration of glass received by MRF (Material Recovery Facilities) and nondeposition in the specific stream. In 2011 were produced in Portugal, 5.159 million tonnes of Mu...

At the southeastern part of Sweden, old art and crystal waste glass has been identified as a hazardous waste due to high weight concentrations of Pb (32.398%), Cd (0.085%), and As (1.976%). The reduction-melting technique was used to investigate the extraction of these trace elements from powder waste glass of particle size < 1 mm. Following a factorial design technique, the experimental result...
