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. The paper provides a description and calculations for a process system that can be used to dispose of waste tires by their st...

Climate change is a global problem and carbon sequestration is one of the possible ways to reduce it. After application of organic matter to the soil, most of the carbon is mineralized and released into the atmosphere where it becomes a part of the greenhouse gas. Biochar is also an organic matter but it contains carbon in a form that is mineralized slowly (hundreds to thousands years). In addition to these complex compounds, it also contains readily available carbon and also aromatic substances which may be toxic...

The results of the studies have shown that the total C reserves of the dark coniferous forest phytomass of the southern taiga in the south-eastern part of the Western Siberia vary from 75.8 to 129.0 t/ha in secondary birch forest and from 48.9 to 110.5 t/ha in fir forests. The analysis of the production process in dark coniferous forests of the southern taiga done using such parameters as absolute value of the C biomass growth, specific annual production of wood and efficiency of assimilation apparatus work, has d...
