Are cities taking action against urban overheating? Insights from over 7,500 local climate actions

One Earth, Год журнала: 2024, Номер 7(5), С. 848 - 866

Опубликована: Май 1, 2024

Mitigating urban overheating is vital to create livable futures. Research on heat mitigation plentiful, while knowledge about the actual measures local governments are implementing limited. This study examines 7,500+ actions by 2,500+ cities under two flagship programs of European Commission. The analysis reveals that cities' strategies pivot around green- and water-based technologies (66% actions) mildly leveraging permeable reflective surfaces (35%) rarely solar shading wind control (8%) or stimuli-responsive/smart systems (2%). Hundreds (1) indicate extreme as a hazard growing intensity and/or frequency, (2) located in hot-summer climatic zones, (3) will experience increasingly frequent heatwaves, (4) host numerous population not reporting any precaution. Moreover, show limited familiarity with combinatorial approaches little attention specific vulnerable groups. Prevention, awareness, social justice should receive more attention.

Circular economy and entrepreneurship in Europe: An analysis of the impact of cultural factors, regulatory framework and rate of entrepreneurship

Environmental Technology & Innovation, Год журнала: 2024, Номер 35, С. 103656 - 103656

Опубликована: Май 6, 2024

The aim of this work is to delve into the phenomenon circular economy (CE) enhance understanding contextual factors that foster its development. We study how countries' cultural values, regulatory frameworks and rates entrepreneurship, affect transition more economies. model proposed tested through a binomial logistic regression analysis sample European small medium-sized enterprises (SMEs), shows such firms are likely adopt CE actions when located in entrepreneurial societies, with individualistic feminine less stringent environmental regulations. Additionally, evidences scale effect, but not an experience CE. Several practical political implications outlined.

Microstructural Investigations Regarding Sustainable Recycling of Ceramic Slurry Collected from Industrial Waste Waters

Sustainability, Год журнала: 2024, Номер 16(3), С. 1123 - 1123

Опубликована: Янв. 29, 2024

Ceramic slurry wastes have a significant hazardous potential when dumped. Their recycling as raw material is sustainable approach for the development of nature-friendly applications. The microstructure and mechanical properties play key role in success this recycling. samples resulting from wall floor tiles production facility were analyzed. mineral composition was investigated by XRD combined with mineralogical microscopy SEM coupled EDX spectroscopy elemental mapping. ceramic contains: quartz, kaolinite, mullite small amounts lepidocrocite. Quartz particles sizes range 5–100 μm kaolinite has around 1 to 30 μm. Iron hydroxide crystallized lepidocrocite finely distributed among aggregates. It makes unable be reused technological process because glaze staining risk, but it does not affect cohesion. Thus, cylindrical prepared at progressive compactions rates follows: 1808.55; 1853.46; 1930.79 2181.24 kg/m3 dried. Thereafter, subjected compression test lower strength 0.75 MPa density higher 1.36 density. compaction enhances binding ability. Young’s Modulus slightly decreases increasing due local rigidizing. This proves ability which properly embeds quartz into coherent resistant structure. fractography analysis reveals that fracture starts on internal pores low throughout layer high compactness. observed indicate proper clay-based binder ecological buildings, avoiding exploitation new clay quarries. Also, might utilized brick production.

An unsustainable rate of resource production and consumption is evident in urban environments. The absence innovative approaches conjunction with the exponential urbanization expansion global population will inevitably result substantial environmental consequences. There are two emerging alternatives: circular economy (CE) metabolism (UM). integration these principles into novel methodology casts doubt on linear model contemporary economic systems, which includes extraction, production, utilization, disposal. In development a distinctive framework known as metabolism, current study has illustrated application principles. We design this to motivate planners decision-makers investigate, develop, supervise ecologically sustainable cities. Scholars from variety academic disciplines, intrigued by intricacies planning, design, administration, can foster interdisciplinary collaboration (CUM) region.
