The article discusses the types of various dusty iron‑containing waste generated in metallurgical and foundry production. Rational waste processing technologies are considered. The analysis of the chemical composition of iron‑containing waste, morphology and particle size is presented. Variants of processing and use technology that are acceptable for the conditions of the Republic of Belarus are proposed.

Plastic waste has been a major issue regarding waste in the world today. Plastic production in the world has reached 8300 million metric tons (Mt) from 1950 to 2015 and of about 6,300 Mt turned into waste. The development of industry and technology is often accompanied by the emergence of environmental impact issue. Encompassed plastic waste in nature causes problems, as it can drift from the land and fill the oceans around the world. Various plastic waste processing technologies have been introduced. Recycling plastic waste into goods, fuel oils and asphalt mixtures are things that have been done enormously. This research aims to make composite materials from used plastics, clay materials, and charcoal. A qualitative experimental method by heating the plastic waste below 270°C. Then, it is mixed with additional materials and casted the composite into a mold to form test specimens. Mechanical testing has been carried out to evaluate the composite. The results show that a composite material comprises plastic waste, clay and charcoal can provide maximum tensile strength of 14.59 N. The tested composite material is found to be 34.20% stronger than the material made of only plastic waste.

Volatile Organic Sulfur Compounds

The emission characteristics of volatile organic sulfur compounds (VOSCs) released from food waste processing plant were detected with cold enrichment-GC/MS. Four main sections of the plant including unloading room, crushing chamber, hydrothermal reactor and aerobic fermentation reactor were selected as sampling points. Results showed that the concentration of VOSCs of the four main sections were 0.085, 0.235, 1.175 and 0.245 mg/m3, respectively. Compared with other stages, the level of VOSCs of hydrothermal reactor was relatively high, and methyl mercaptan (MeSH) was the most abundant compound at this section. In order to remove the pollution of MeSH, modified activated carbon was used as the adsorbent. The influences of modified conditions, such as drying temperature, H3PO4 concentration and impregnated time on adsorption were investigated. Results showed that the amounts of acid groups and BET surface area of activated carbon had a significant impact on the adsorption capacity. When the drying temperature was 70°C, the H3PO4 concentration was 15% and the impregnated time was 3.0 h, the adsorption capacity of MeSH achieved the maximum value of 22.068 mg/g.
