Opis:
Theoretical background: The strategies for the development of the European Union presented at the beginning of the new century portrayed bioeconomy as a modern concept of ensuring the sustainable and dynamic development of EU member states and bioeconomy itself became an important area of interest to the EU authorities. At present, the development of bioeconomy is a significant element of implementing the economic development strategies of respective EU member states.Purpose of the article: This article aimed to examine the international competitive position of Poland in the bio-based products trade on the common EU market in comparison to other member states of the EU.Research methods: The competitive position in bio-based products trade was evaluated based on the following indicators: balance of trade, Poland’s share in EU exports and imports, trade coverage ratio, import penetration ratio, relative export orientation ratio, intra-industry trade intensity ratio, and export specialisation index. Groups of bio-based products identified based on an official classification of products according to CPA, version 2.1, consistent with NACE. The analysis was based on data derived from the Eurostat database for the years 2008–2017.Main findings: The surveys imply that in 2008–2017, the competitive position of Poland improved mostly in the Forestry, Wood products, Paper and paper products, and Food sector, and in particular in the Tobacco products sector, which has been in line with the bioeconomy development strategy of the European Union.

Opis:
This paper quantitatively shows the effect of run-of-mine (ROM) feed grade on flotation plant capacity, and also the combined effects of different feed grades and the size reduction alternative combinations on the project economics. Project economics are defined as CAPEX and OPEX The project profitability was estimated based on a “Cash Flow Model” along the life of the mine, which is ten years. The parameter for tracking project return or profitability is called NPV and IRR (internal rate of return), respectively. These parameters are standard parameters for control of project return in all engineering studies. In the scope of the study, there are a series of case studies including three different comminution alternatives in combination with three different ROM feed grade alternatives. Therefore, the nine case studies were compared based on economics which resulted from different equipment combinations and as well as the different types/amounts of process consumables. Among all the cases, Case 1 (Conventional circuit with 0.1% feed grade) gave the lowest CAPEX whereas Case 9 (High Pressure Grinding Rolls_HPGR circuit with 0.3% feed grade) gave the highest CAPEX. OPEX wise, Case 7 (HPGR circuit with 0.1% feed grade) produced the lowest whereas Case 6 (Semi-Autogenous Ball mill Crusher_SABC circuit with 0.3% feed grade) gave the highest value of OPEX. The NPV of the HPGR circuit with 0.3% feed grade case was found as maximum, which showed the quantitative effect of feed grade and equipment combination on flotation plant economics.
