However, evaluating the ”greenness” of a manufactured product is a complex task due to data availability, varying definitions of ”green” products, and diverse environmental impacts. This research addresses this challenge by identifying, classifying, and prioritizing Key Performance Indicators (KPIs) to assess green manufactured products, specifically within the Indian manufacturing context. A systematic approach was employed, incorporating Pareto analysis and the Full Consistency Method (FUCOM) to identify the most significant KPIs and assign them priority. Industry, academia, and customer perspectives were considered, resulting in distinct priorities. Industry experts prioritize economic aspects, while academia emphasizes health and safety. Customers focus on air quality and greenhouse gas emissions. This diversity of perspectives underscores the need for businesses to tailor their sustainability strategies to meet evolving customer demands while considering economic implications. The study identifies 30 vital KPIs crucial for evaluating green product manufacturing, encompassing dimensions like waste management, energy efficiency, workplace safety, and societal compliance. By considering these KPIs, businesses can make informed decisions to improve sustainability, reduce their environmental footprint, and align with consumer expectations. The findings provide a roadmap for businesses and policymakers to develop more effective strategies, targeting diverse stakeholder groups and promoting the production and use of green products. This research contributes to the growing body of knowledge in sustainable manufacturing and serves as a valuable tool for manufacturers in India and beyond, aiding them in navigating the complexities of manufacturing green products and meeting the rising demand from environmentally conscious consumers.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"3 1","pages":"Article 100114"},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949736124000411/pdfft?md5=9ba3dcfdd281aa8cb40d9aa71230f8ee&pid=1-s2.0-S2949736124000411-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141842899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a structured questionnaire and volunteer farmers (N = 595), we investigated the potential for adoption of BSF larvae composting technology for sustainable agricultural waste management in Greater Ahafo-Ano. Almost all surveyed farmers declared they generated a significant amount of biowaste on their farms and were willing to learn how to use the BSF-based technology to transform it into value-added products. The waste generated was mainly disposed of in pits at Ahafo-Ano South-East (56.2%), by composting at Ahafo-Ano South-West (34.9%) and by sale at Ahafo-Ano North (34.4%). Across the three districts, awareness of the BSF was very low – 14.5% in Ahafo-Ano South-East, 14.1% in Ahafo-Ano South-West and 0.5% in Ahafo-Ano North. However, high acceptance of the technology was recorded. It was found that about 8% of farmers surveyed in Ahafo-Ano South-East had already tried BSF farming on a small scale.

In contrast, the waste treatment option of the foundation concrete contributes substantially to the sustainability performance of the examined scenario. The sustainability performance of these technologies could be enhanced by the operation of dedicated concrete and composite materials recycling facilities close to wind parks, following cross-sectoral approaches.

A significant rise in global temperature at the end of the century is estimated to be 2.4 °C, which necessitates action. The growth of energy needs urges scholars/researchers to think about developing suitable solutions. The key goal is to achieve zero-net emissions by 2050 in accordance with the goals outlined in the Paris Agreement (Climate Accords). To accomplish this, it is vital to have a strong strategy that initially includes high emissions reduction goals and addresses the challenges of global warming on our planet. Therefore, by 2050, the global energy strategy aims to eliminate emissions from the energy industry to zero. It is worth noting that most energy of the energy consumed comes from transport, power generation, industry, and buildings. The use of renewable technology is a method that is widely recommended to eliminate such challenges. Solar energy has two main technologies: solar photovoltaic (PV) and concentrating solar power (CSP), which have great potential in fulfilling energy needs. This work provides insight into solar energy technology’s role in global decarbonisation and towards net-zero emissions by 2050 through wide deployment and energy yield. The perspectives of solar energy technologies can save the environment by reducing emissions and energy supply, lowering energy bills, and creating job opportunities.
