Green Chemistry & Technology Letters [eISSN 2455-3611] aims to publish the latest developments in various domains of green chemistry, green engineering and technologies, and related education and government policies. Journal prefers articles that explore various dimensions of design principles of green and sustainable chemistry and engineering.
Journal encourages researchers to publish new and experimental forms of research, replication studies, and even failed and negative results. It publishes two issues in a year in January and July.
Designing with a 'Life Cycle Thinking' Approach
Life-cycle thinking is an approach that considers the entire life cycle of a product or system, from raw material extraction and manufacturing to use, disposal, and beyond. It aims to assess and minimize the environmental, social, and economic impacts associated with all stages of a product's life. Applying life-cycle thinking in engineering activities involves considering the following aspects:
- Design Phase: During the design phase, engineers can incorporate life-cycle thinking by considering the potential impacts that different design choices may have throughout the life cycle of the product. This includes evaluating the selection of materials, manufacturing processes, energy consumption, and waste generation. By optimizing the design for sustainability, engineers can reduce the environmental footprint of the product.
- Material Selection: Engineers can assess the environmental and social impacts associated with different materials and choose those with the least harmful effects. This includes considering factors such as resource depletion, energy consumption, emissions, and toxicity. Additionally, they can explore alternatives to virgin materials, such as recycled or bio-based materials, to minimize the use of finite resources.
- Manufacturing and Production: Life-cycle thinking in engineering activities involves optimizing manufacturing processes to reduce energy consumption, waste generation, and emissions. Engineers can explore techniques like lean manufacturing, energy-efficient technologies, and process optimization to minimize the environmental impact of production.
- Use and Maintenance: Considering the use phase of a product is crucial in life-cycle thinking. Engineers can design products that are energy-efficient, durable, and require minimal maintenance. This can involve incorporating energy-saving features, developing efficient operating procedures, and providing clear instructions for maintenance and repair.
- End-of-Life Management: Engineers can plan for the end-of-life stage of a product by incorporating strategies such as recycling, remanufacturing, or designing for disassembly. By considering the ease of material recovery and recycling during the design phase, engineers can facilitate the transition to a circular economy and reduce waste generation.
- Stakeholder Engagement: Life-cycle thinking also involves engaging with stakeholders such as consumers, suppliers, and regulators to understand their expectations and concerns regarding the product's life cycle. This engagement can lead to valuable insights and identify areas for improvement in terms of sustainability and social responsibility.
By incorporating life-cycle thinking into engineering activities, engineers can make informed decisions that consider the broader impacts of their work.
This approach promotes sustainable development, reduces environmental burdens, and contributes to the creation of more environmentally friendly and socially responsible products and systems.
