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.

High-Risk Biodegradable Waste Processing By Alkaline HydrolysisBiodegradable waste is by definition degraded by other living organisms. Every day, meat industry produces large amounts of a specific type of biodegradable waste called slaughterhouse waste. Traditionally in Europe, this waste is recycled in rendering plants which produce meat and bone meal and fat. However, feeding animals with meat and bone meal has been banned since the outbreaks of bovine spongiform encephalopathy (BSE). In consequence, new slaughterhouse waste processing technologies have been developed, and animal wastes have now been used for energy production. Certain parts of this waste, such as brains and spinal cord, are deemed high-risk substances, because they may be infected with prions. Their treatment is therefore possible only in strictly controlled conditions. One of the methods which seems to bear acceptable health risk is alkaline hydrolysis. This paper presents the results of an alkaline hydrolysis efficiency study. It also proposes reuse of the obtained material as organic fertiliser, as is suggested by the analytical comparison between meat and bone meal and hydrolysate.

An important direction of forming an effective system for recycling waste of various genesis is to optimize the processes of their treatment using the latest information resources. The paper deals with theoretical studies of directions for the systematization and optimization of anaerobic waste processing technologies using ontological tools based on information resources. Significant scientific support to biochemical research is provided by electronic bioinformatics databases such as KEGG, BacDive, and EAWAG-BBD, etc., which provide access to a collection of graphical representations and text descriptions of metabolic or signal pathways, schemes of regulation of biological processes, information about the organism. They cover various aspects of bacterial and archaic biodiversity, information on microbial biocatalytic reactions and biodegradation pathways of mainly xenobiotic chemical compounds. Also, in the course of work based on analytical data of electronic databases of bioinformatics, in particular, the interaction of necessary ecological and trophic groups of microorganisms, biochemical simulation of anaerobic waste processing with biofuel production was carried out. Keywords: waste disposal, bioinformatics database, anaerobic fermentation, biofuel.
