The mining method selection for underground mining is one of the most important decisions when designing a mine. This selection depends on the mining-geological, mining-technical and economic factors. The mining method selection for underground mining can be described as a multi-criteria decision-making process, as several factors are involved in the selection process. In this paper, a methodology for rational and optimal mining method selection for underground mining of metallic mineral resources has been developed. First, a rational selection of the four best-ranked mining methods for underground mining is performed using numerical methods (Nicholas' approach and the modified approach of Nicholas, i.e., UBC selection of mining method). This is followed by the optimal selection of underground mining method using multi-criteria decision-making methods (ELECTRE, PROMETHEE, AHP, and integrated AHP-PROMETHEE) and by comparing the obtained rankings, the optimal mining method is selected.

Municipal solid waste management is still one of the major environmental challenges at a national level, and although with national and regional waste plans in place, the Republic of North Macedonia with its eight regions has only one standard landfill active, and at least 54 non-standard municipal landfills and hundreds of dump sites and old landfills. In the light of the soon expected regional establishment of an integrated and self-sustainable waste management system in the eastern and north-eastern regions, to increase awareness by the local population and hospitality enterprises for source separation schemes of organic waste, as largest producers of organic waste, Goce Delcev & Hellenic Mediterranean Universities together with Municipality of Katerini, Municipality of Yermasoyia and Municipality of Probistip launched joint project co-funded by EU, Utilizing pay-as-you-throw Systems and Autonomous Composting Units for Biowastes Management in Touristic Areas (BIOWASTE). This paper aims to present the environmental benefits of the project implementation and scaling up process that was developed, aiming to expand the BIOWASTE project processes in the whole Municipality of Probishtip.
