The research studies waste generation and waste management from a sustainability perspective in three areas: separate waste collection, food waste, and textile waste from fast fashion. It analyses environmental, economic, behavioural, technological and social factors together, within the framework of the circular economy, resource efficiency and climate protection. The analyses use observed and survey data and quantitative methods.

This research field focuses on the interrelations of political economy and economic reforms mostly in the post-Soviet region, with particular emphasis on institutional change, the role of democratic institutions, the impact of populist leadership, and the challenges of European integration.

The research presents a new measurement framework, the Rhetorical Environment Framework (REF), for studying political communication. Its core idea is that political actors’ communication is not a series of isolated messages but can be understood as a persistent yet open rhetorical environment. The framework measures two observable properties of this environment (its frequency and its intensity) separately and then interprets them together. The measurement is theory-driven, modular, and applicable to any actor, issue or domain. The procedure relies on human coding and LLM annotation with a validated, pre-specified protocol.
