Nowadays, dealing with organic waste (or biowaste) remains a global phenomenon. Especially developing countries worldwide generate more than 50 percent organicwaste. In the European Union (EU) with a share of 34%, biowaste is a dominantfraction of the municipal waste (EEA, 2020). Therefore, separate collection at source and environmentally sound treatment of biowaste are of key importance. An intensive optimisation of biowaste separate collection is needed to balance demands of municipal representatives and households’ needs. Based on the mixed-method approach we developed a MCDA model complemented by expert-based weighting assessment and combined with the GIS localisation tools aimed at the optimisation of biowaste container locations that reflects various spatial conditions, preconditions for the localisation of containers and its cost intensity. We concluded that changing the density of containers, distance between the address point and container, and selecting container locations that respect the habits of households and demands of the collection technology significantly affect the total and collection costs. We confirmed that the decreases in the total costs were not significant for maximum walking distances of over 95 m, and would approach zero for distances of over 230 m. When the maximum walking distance exceeds 268 m, 40% of all inhabitants would not participate in the system as it would be inconvenient for them. A recycling campaign is needed to increase their willingness to participate in the system. We provided arguments for decision-makers how to balance convenience of the biowaste separation system and collection costs by proper localisation of biowaste containers.

During recent decades, the debate on how to sustain urban mobility has accelerated. Transport decision-making has been more reflective of sustainability issues and quality of life in cities; this process has especially accelerated with the setting of modern urban mobility planning concepts, substantially focusing on transport demand regulation and management, and Sustainable Urban Mobility Plans taking over the role of cities’ primary transport-related strategic documents. The approaches to sustainable mobility visioning and planning differ within cities, as do their key stakeholders’ opinions. Our research aims to reveal the main shared viewpoints on the preferred paths towards sustainable urban mobility. We use the Q method, which is a statistical method to study subjectivity. It enables determination of characteristic shared viewpoints on a particular subject. A qualitative analysis assessing subjective opinions is combined with the quantitative approach of a factor analysis of statements ranked by respondents. The study was undertaken on 36 carefully selected stakeholders situated within the Czech Republic. Our results indicate that even stakeholders sharing the same definition of sustainable urban mobility may substantially differ in regard to their ideas on how to achieve it. Furthermore, we show that some of the attitudes expressed and measures appreciated by our respondents would not be recognised as sustainable by environmentalists. There is still a wide gap between sustainable mobility theory and its implementation in practice. All these findings represent barriers to sustainable mobility development in urban areas. Therefore, the paper also conveys relevant policy implications.

The generation of recyclables in the Czech Republic has long been under the European average, but the proportion from municipal waste as a whole has been growing over the past few years. Previous research in the Czech Republic mainly focused on organizational or situational factors explaining recycling performance in municipalities. This study focuses on individual characteristics that are connected, among other things, to ongoing demographic changes. Currently ongoing sociodemographic development in the Czech Republic, as well as other developed countries, influence a broad range of aspects of social life, including waste generation and its structure. This paper aims at quantifying the relation between the sociodemographic characteristics of municipality inhabitants and recyclable generation. For this purpose, 13 variables describing inhabitants, households, and housing in 4897 Czech municipalities were selected that could influence the generation of recyclables according to foreign studies. Data were analyzed using multidimensional linear regression. Even though the resulting model only explains 9%, it is statistically significant and implies that sociodemographic variables can help explain recyclable generation. From this point of view, important variables are average household size, share of tertiary educated people, share of family houses, purchasing power per person, percentage of people employed in agriculture, and sex ratio. To increase the explained variability and emphasize local differences in recyclable generation, we also used geographically weighted regression (GWR). GWR results show that, to understand waste generation (at least in the Czech Republic) on a municipal level, it is necessary to also consider spatial effects and regional specifics.
