The European Green Deal is the new strategy for economic growth adopted by the European Commission (EC) in late 2019. One of the most important tasks in the realisation of this strategy is the mobilisation of the industry for a clean and circular economy (CE). Currently, the European Union (EU) is in the process of transformation towards a CE model, which was announced in 2014. The CE assumes a transition from a linear model based on take–make–dispose to a circular model, in which waste, if it arises, becomes a valuable resource. At the same time, it is recommended to use raw materials (RMs) more efficiently and to recycle them. The EC underlines that both changes in the management of mineral resources in individual member states and their effects should be monitored. Therefore, in 2018, the EC pointed out issues related to RM management as important elements of the monitoring framework in transformation process towards CE. The paper presents strategic directions aimed at sustainable and circular RM management in the EU, with a strong emphasis on the key elements of sustainable development—environmental, economic and social. Moreover, the importance of mineral resources management in the EC in the context of transformation towards the European Green Deal and CE is presented, and the results of selected CE indicators related to the RMs, and indicators that present sustainable RMs management are discussed. The core of the paper is presentation of a set of recommended actions which should be taken in coming years with strong emphasis on the implementation of the sustainable development (SD) principles. RM management faces a number of challenges, primarily in achieving increased levels of critical raw materials (CRMs) recycling, as well as the greater involvement of stakeholders themselves and awareness raising in the field of SD and CE among enterprises operating in the RMs sector. Currently, all member states are working together to accelerate the transformation process in the area of CE and the European Green Deal, e.g., by implementing national CE programs. A great opportunity to accelerate the transformation process is the new financial perspective for projects under the balanced and circular management of RMs—Horizon Europe, which plans to finance the new projects on RMs management and recycling.
Municipal waste management has been an area of special interest for the European Commission (EC) for many years, especially in the transformation process towards a circular economy (CE), which is a priority of the European Union’s (EU’s) economic policy. This paper presents the overview of the Polish waste management system (WMS) and the CE-related tasks indicated in the Polish CE Roadmap. Despite the fact that Poland is one of the countries that generates the least waste per capita (329 kg in 2018) in the EU (489 kg), it still has problems with adapting the levels of municipal waste recycling to European requirements (34.3% in 2018, EU average 47%), which result from the lack of sufficient infrastructure for waste management and the insufficiently developed public awareness and behaviors. The current paper presents an inventory of the recommended actions, which support transformation towards CE in municipal waste management. These actions have been grouped into six core principles of circularity, indicated in the ReSOLVE framework: Regenerate, Share, Optimize, Loop, Virtualize, and Exchange. In each of presented areas, recommended tasks and actions were identified that should be taken by governments and residents themselves, such as landfill remediation, use of selected municipal waste fractions for economic purposes, sharing products with co-users, waste recovery, remanufacturing products or components, virtual solutions in everyday life to reduce the amount of generated waste, or replacement of household appliances by items with a higher energy class. An implementation of specific actions indicated in the paper could positively influence transformation towards CE in Poland. Because the presented examples of actions are model solutions, they can also be used in other countries and regions.
The arousal level of words presented in a Stroop task was found to affect their interference on the required naming of the words’ color. Based on a dual-processes approach, we propose that there are two aspects to activation: arousal and subjective significance. Arousal is crucial for automatic processing. Subjective significance is specific to controlled processing. Based on this conceptual model, we predicted that arousal would enhance interference in a Stroop task, as attention would be allocated to the meaning of the inhibited word. High subjective significance should have the opposite effect, i.e., it should enhance the controlled and explicit part of Stroop task processing, which is color naming. We found that response latencies were modulated by the interaction between the arousal and subjective significance levels of words. The longest reaction times were observed for highly arousing words of medium subjective significance level. Arousal shaped event related potentials in the 150–290 ms time range, while effects of subjective significance were found for 50–150, 150–290, and 290–530 ms time ranges.
Affective meaning of verbal stimuli was found to influence cognitive control as expressed in the Emotional Stroop Task (EST). Behavioral studies have shown that factors such as valence, arousal, and emotional origin of reaction to stimuli associated with words can lead to lengthening of reaction latencies in EST. Moreover, electrophysiological studies have revealed that affective meaning altered amplitude of some components of evoked potentials recorded during EST, and that this alteration correlated with the performance in EST. The emotional origin was defined as processing based on automatic vs. reflective mechanisms, that underlines formation of emotional reactions to words. The aim of the current study was to investigate, within the framework of EST, correlates of processing of words differing in valence and origin levels, but matched in arousal, concreteness, frequency of appearance and length. We found no behavioral differences in response latencies. When controlling for origin, we found no effects of valence. We found the effect of origin on ERP in two time windows: 290–570 and 570–800 ms. The earlier effect can be attributed to cognitive control while the latter is rather the manifestation of explicit processing of words. In each case, reflective originated stimuli evoked more positive amplitudes compared to automatic originated words.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
