Effect of microwave pretreatments were studied under three microwave power levels of 160, 320, and 480 W for an exposure time of 60 s. Drying time during convective drying without microwave pretreatment was 5.5 h, which was decreased by 18.2%, 27.3%, and 36.4% at microwave powers of 160, 320, and 480 W respectively. Moisture content of mace decreased from 45.66 ± 1.14% to 6%. under various drying conditions. The two-term exponential model fitted the drying data under optimized conditions. The drying efficiency and exergy efficiency of the microwave assisted drying of mace was observed to be 29.53% and 26.74%, respectively. The values of economic attributes indicated the benefit cost ratio of 1.9 and payback period of 2.1 years. The sustainability index and environment destruction coefficient of the system was determined to be 1.10 and 2.41, respectively. Waste energy ratio, environmental impact factor and improvement potential of the developed drying process was 0.72, 1.52, and 0.46, respectively. The study concluded that microwave at optimal power of 320 W can be utilized for commercial production of mace with better retention of essential oil, oleoresin and color.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mineral carbonation (MC) of fly ash (FA) using acid mine drainage (AMD) can reduce CO2 and the negative environmental impact of FA including AMD from coal mining activity. The present study examined the direct carbonation (DC) of FA using pure water and AMD in a 600 mL autoclave pressure reactor. A preliminary study was conducted to observe the leaching behavior of FA in water and AMD. DC was conducted to determine the effect of solid-to-liquid ratio (0.2 and 0.5 g mL−1), stirring speed (100 and 400 rpm) and CO2 pressure (1–4 MPa) on the carbonation performance. The maximum calcium carbonate content in the carbonated FA was 4.33 wt% with a 60% conversion of calcium to CaCO3 for DC with pure water. The electricity required by the process was 18.9 kWh t−1-CO2, corresponding to 0.019 t-CO2 emitted t−1-CO2 fixed in FA. DC using AMD was effective and the maximum CaCO3 content in FA was 6.68 wt%. This was due to the additional calcium content and enhanced calcium extraction provided by AMD. The actual CO2 uptake capacity was 29.4 g-CO2 kg−1 fly ash. Studies on AMD as a reaction solvent for MC are few but can improve the carbonation performance of FA. Hence, the method can be viable for mining industries to mitigate negative environmental impacts and generate additional revenue through carbon credits.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ep.14545","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It calculated the Green Development Power Index (GDPI) using an objective weighting method and analyzed the spatial and temporal evolution of the GDPI in the western region from 2000 to 2020. The results of the paper showed that: (1) The level of green development power in the western region generally showed a progressive distribution pattern, with higher values in the north and west, and lower values in the south and east. The overall level of green development was positioned between the levels of stronger and strong development power. (2) From 2000 to 2020, the average values of the GDPI in the western region were 0.612, 0.613, 0.615, 0.610, and 0.594, respectively. The proportions of areas with stronger levels of green development power were 51.2%, 51.3%, 51.3%, 51.1%, and 47.0%, respectively. (3) Between 2000 and 2020, the level of the GDPI in the western region as a whole was in a basically stable state. The strong development power was mainly concentrated in desert Gobi regions such as Xinjiang, Inner Mongolia, Qinghai, and Gansu, which are characterized by lower altitude. In contrast, weaker development power was primarily found in regions like Sichuan and Shaanxi, which experienced rapid economic development, high levels of urbanization, and high population density.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Cyclic voltammetry and galvanostatic charge discharge curves indicate an improvement in the electrochemical behavior, resulting in a marginal increase in the specific capacitance values at higher exfoliation temperatures. The improvement is predominantly due to the change in the structural disorder in the system accompanied by the incorporation of oxygen functional groups which act as electrochemical active species. The exfoliation of wood charcoal at 160 and 200°C yield a specific capacitance of 6.23 and 12.24 F/g at a current density of 0.01 A/g. The ESR values representing the overall resistance of the system are observed to be 6.07 Ω for 200°C as opposed to 10.41 Ω of the bare material, making the material more conducting. The drastic change in the structural morphology along with the optimal amount of oxygen functional groups can be the reason for this behavior. The acquired results offer useful information for investigating the possibilities of fabricating supercapacitors with wood charcoal by tuning the defects of the system.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, limited resources began to decrease rapidly. The destruction on the natural environment, environmental pollution and the effects of global warming have reached alarming levels. On the other hand, the need for raw materials and energy continues to increase. At this point, it is extremely important to meet today's needs in a sustainable way, without causing environmental pollution and without consuming limited resources. In order to meet the need for sustainable building materials, studies on the use of plant biomass in the production of building materials are increasing due to reasons, such as having low environmental impact, low cost, and renewable. Since building materials produced from plant biomass are largely biodegradable, they also contribute to the prevention of environmental pollution. In this context, the plants examined in the study were examined in detail in an order from woody plants to herbaceous plants and from plants commonly used in architecture to less commonly used plants.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gas-chromatography methods were used to monitor CH4 and soil CO2 emissions, while assessing dry matter, carbon content, and carbon fixation capacity of tomato organs throughout the growth period. Additionally, a system for evaluating the net ecosystem carbon budget of facility tomatoes was developed based on net primary productivity. Results indicated reduced CH4 and soil CO2 emissions with decreased irrigation and nitrogen application. Dry matter, carbon content, and carbon fixation of tomato organs initially increased with reduced nitrogen and irrigation but then declined. The W2N2 (80% ET0-192 kg·ha−1) treatment showed maximal values for dry matter, carbon content, carbon fixation, net primary productivity (NPP), and gross primary productivity (GPP). Findings suggest a positive net ecosystem carbon budget under reduced water and nitrogen conditions, indicating carbon absorption.

Given the substantial demand on water resource during anaerobic digestion (AD), this study investigated the feasibility of substituting pure water with sewage as the main water source for AD using six diverse lignocellulosic wastes (rice straw, vinegar residue, cattle manure, sheep manure, napkin, and office wastepaper) as feedstocks. The results showed that the methane production of lignocellulosic waste + raw wastewater (WW) during AD increased by at least 5% compared with the control groups. Specially, the cumulative methane yield of napkin mixed with the WW reached to 218.3 mL/gVS with the increase of 47.8% compared with the control group (147.7 mL/gVS). The results indicated that the relative abundance of characteristic bacteria and methanogenic archaea during AD was closely related to the kinds of feedstocks and water source. The addition of WW increased the relative abundance of bacteria and archaea in the digester, which might be the main reason for the higher methane production with the addition of WW. Treated wastewater and reclaimed water had a relatively neglectable impact on the microbial community structure in AD. This study not only saved water resources in AD but also provided a strong reference for resource utilization of sewage and organic solid waste.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
