“…The scarcity of natural resources is a developing worry in many places in the world; on the other hand, rapid population growth and growing industrialization are putting significant strain on the world’s scarce resources, resulting in shortages in many areas [ 55 ]. Further, around 1.3–1.8% of the world’s fossil fuel consumption is attributable to the manufacturing of nitrogen fertilizers [ 56 ].…”

Wheat (Triticum aestivum L.) is a strategic agricultural crop that plays a significant role in maintaining national food security and sustainable economic development. Increasing technical performance considering lowering costs, energy, and environmental consequences are significant aims for wheat cultivation. For drylands, which cover approximately 41% of the world’s land surface, water stress has a considerable negative impact on crop output. The current study aimed to assess the environmental aspects of chemical fertilizer in combination with compost in dryland and irrigated winter wheat production systems through life cycle assessment (LCA). The cradle-to-farm gate was considered as the system boundary based on one tone of wheat yield and four strategies: D-C (dryland with compost), D (dryland without compost), I-C (irrigated with compost), and I (irrigated without compost). Based on the results, the highest and lowest amounts of wheat yield were related to the I-C and D strategies with 12.2 and 6.7 ton ha−1, respectively. The LCA result showed that the I strategy in comparison with other strategies had the highest negative impact on human health (49%), resources (59%), ecosystem quality (44%), and climate change (43%). However, the D-C strategy resulted in the lowest adverse effect of 6% on human health, 1% on resources, 10% on ecosystem quality, and 11% on climate change. Utilizing a combination of fertilizer and compost in dryland areas could ensure a higher yield of crops in addition to alleviating negative environmental indicators.

“…Additionally, the conservation of essential raw materials such as fertile clay (0.9 MT), iron ore (0.3 MT), coal (0.18 MT), limestone and additives (0.07 MT), and natural wood becomes feasible, translating into substantial savings of vital natural resources-no small feat for a country grappling with resource constraints. Furthermore, this conservation effort implies a diminished need for energy in the extraction of natural resources [64].…”

Findings from the study reveal that Construction and Demolition Waste (CDW) in Bangladesh mainly consists of concrete (56%), brick (15%), mortar (9%), metal (6%), and ceramics (6%). However, the exact constitution may differ depending on the structure and type and structure of building. Additionally, the collective CDW produced in Dhaka, Chittagong, Khulna, Rajshahi, Barisal, and Sylhet totals 3.71 million tons (MT). The WGR of construction and demolition waste is assessed through regression analysis. The mean WGR for Construction and Demolition activities in the fiscal year 2022–2023 are notably recorded at 64.68 kg/m2 and 1626.97 kg/m2, correspondingly for the twelve city corporations of Bangladesh. Unfortunately, a substantial portion of this waste is inadequately disposed of in landfills. The study highlights the potential for entrepreneurial initiatives in recycling materials like concrete, brick, mortar, metal, ceramics, and timber, leading to reduced CO2 emissions and energy consumption. The estimated economic value of recycling concrete, brick and mortar in major cities is approximately 104.5 million USD and 0.45 MT of CO2 reduction from recycling brick and metals from major cities. These findings provide crucial quantitative data for government bodies and industries aiding in developing strategies for CDW management in Bangladesh.

“…The rising global energy demand has intensified concerns about a potential energy crisis ( Semieniuk et al, 2021 ; Bhuiyan et al, 2022 ; Farghali et al, 2023 ). While conventional fossil fuels remain dominant, they pose significant challenges due to their finite availability and associated environmental consequences, particularly greenhouse gas emissions ( Kalair et al, 2021 ; Arzaghi and Squalli, 2023 ; Wang and Azam, 2024 ). Solar energy, an environmentally friendly and sustainable option, is attracting increasing attention ( Guney, 2016 ; Zou et al, 2023 ).…”

With escalating energy demands, solar power stands out for its abundance and renewable advantages, presenting a paramount sustainable solution. Herein, we tactically incorporate phase change material (PCM) into solar energy systems, resulting in substantial enhancements in energy storage and utilization. Through numerical simulations, the thermal dynamics and phase change processes associated with various heating methodologies are investigated, aiming to achieve optimal thermal performance and energy efficiency. Detailed analysis of temperature dynamics within the PCM under two distinct heating methods reveals pivotal thermal fluctuations in both the PCM and water during heat release. The results indicate that bottom heating promptly induces rayleigh convection, resulting in a uniform temperature and a stable phase interface, which are desirable for heat transfer. In contrast, central tube heating concentrates heat transfer in the upper PCM layer, leading to an uneven phase interface and thermal stratification. Configurations with two horizontally aligned heating tubes result in a 36% reduction in melting duration compared to the single central tube setup, highlighting enhanced efficiency. Additionally, the bottom heating approach demonstrates improved energy storage efficiency in both the initial and second heating cycles. These findings highlight the potential of PCM-integrated combined heating systems for solar energy capture, confirming their efficiency and practicality in addressing modern household energy demands.
