Nowadays, along with creating materials with enhanced mechanical characteristics, it became important in the light of ecological problems, to design eco-friendly materials capable to disappear with time after fulfilling functions, in other words to develop biodegradable mechanically strong materials. The chemistry and technology of biodegradable polymers is one of the most important and rapidly developing fields of modern polymer science. A lot of biodegradibel polymers (BPs) were created mostly for medical applic...

One of the significant problems in terms of the mining impact on environment is abandoned (due to various factors) deposits and tailings accumulated on landfills. In addition, one of the most important resources for the development of mining is the inclusion of raw materials (as non-industrial stocks) in the economy. There are two ways to solve these problems: a) to achieve economic profitability of the deposit by improving the technologies of extraction and processing of basic raw materials, and b) to develop inn...
