Furthermore, the utilization of <em>Sargassum</em> compost could offer a cost-effective alternative as a soil amendment, especially in the face of rising fertilizer costs.

Over the past few years, there has been a growing recognition of the potential of agricultural crop waste in mitigating greenhouse gas (GHG) emissions and promoting global carbon neutrality. Despite lacking practical management options, open-field burning of crop residue contributes significantly to greenhouse gas emissions and air pollution. This challenge may be addressed by producing biochar through the pyrolysis of agricultural crop residues. A biochar application in agriculture can contribute to reducing global warming through the sequestration of atmospheric carbon and reducing greenhouse gas emissions from the soil. As part of the life cycle assessment of biochar, the yield and greenhouse gas emissions during its production are critical factors, which emphasize the importance of selecting a production method suitable for producing biochar. The objective of this paper is to present a comprehensive overview of the environmental and agronomic advantages associated with biochar, along with a detailed analysis of its life cycle assessment (LCA). Furthermore, it provides an overview of how biochar can facilitate local energy production and contribute to sustainable resource management within the nexus of agroecosystems, environment, and energy.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"19 ","pages":"Article 200173"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49747907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the study aims to investigate the correlative influence of consumer ethical beliefs (e.g. idealism and relativism), environmental ethics, moral obligation, and willingness to use green products on green consumption. We draw on self-identity theory and the theory of planned behavior. A convenience sampling technique and analyzes from 262 responses were applied through structural equation modeling. The results disclose that idealism, relativism, environmental ethics, moral obligation and willingness to use green products have a positive influence on green consumption. In addition, environmental ethics and moral obligation relatively influence the willingness to use green products.

This article reviews diverse metal recovery technologies, including adsorption, electrocoagulation, chemical precipitation, resin adsorption, extraction, membrane separation, and electrodeposition. Most studies successfully transfer Cu<sup>2+</sup> or Ni<sup>2+</sup> from electroplating wastewater to intended metal carriers in lab-scale technologies, thus purifying the wastewater and concurrently enriching desired metals. However, these studies primarily focus on lab-scale heavy metal enrichment and purification, often yielding a mixture of metals with impurities or concentrated salt solution. The importance of reutilization of the recovered metal mixture or metal salt solution, largely unexplored in existing research, is pivotal for sustainability. We propose that future works prioritize pilot-scale experiments, emphasizing reutilization strategies for recovered materials. Consequently, a comprehensive environmental impact evaluation of metal recovery from electroplating wastewater could be made via life cycle assessment, underscoring the importance of reuse in this process.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"19 ","pages":"Article 200170"},"PeriodicalIF":0.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49748456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
