A novel densified mixture design algorithm was used incorporate high quantity fly ash rice husk as an eco-binder. Results showed specimens with added exhibited improved mechanical strength, dynamic modulus elasticity rigidity, lower drying shrinkage while ones PP reductions compressive strength modulus.

The objective of this article is to assess the carbon footprint across Continuous Deep Mixing Method (CDMM) life cycle, considering its implementation in context sustainable, zero-emission, and decarbonising construction. Amidst global climate change challenges greenhouse gas emissions construction sector, CDMM emerges as a potentially effective solution mitigate environmental impact. This study aims address gap existing scientific literature by evaluating aspects application, with focus on identifying primary emission sources. research extends beyond conventional materials include energy consumption from equipment transportation, offering holistic view technology’s analysis identified cement major source for CDMM, underscoring potential an alternative traditional geotechnical methods, line integrated design solutions meeting growing social expectations sustainability. added value comes data derived actual project, enabling realistic assessment CDMM’s impact resource efficiency.

Energy policy has a significant impact on the state of environment and, therefore, residents’ health and life expectancy, especially in highly urbanized areas. Reducing emissions is currently one necessary actions that must be taken at scale individual countries to ensure sustainable development. The article aims identify best ways shape energy by evaluating development scenarios for air protection their environmental impact. realization goal based data included three groups: (1) Economic factors, Health Demographic factors; (2) Clima-e related economic losses, Renewable sources electricity, heating, cooling, Premature deaths due exposure fine particulate matter (PM2.5), impacts pollution, Population change; (3) balance crude rates national level, GDP per capita purchasing power PPS, GDP, principal components; covering 36 EU 2019 2021. study proposes an advanced methodology assessing strategies integrating Technique Order Preference Similarity Ideal Solution (TOPSIS) Bayesian networks (BN) incorporating them into multicriteria decision-making (MCDM) support system. TOPSIS model BN allowed illustration features many criteria identification relationships between scenarios, allowing selecting way develop policy. results showed 60.39% chance achieving success extending residents five years. At same time, most favorable path was scenario promoting activities aimed reducing pollution introducing renewable produce used lighting preparing domestic hot water urban By presenting possible probability success, it achieve practical level country European cities also city inhabitants, as presented authors this study.
