Concept
Circularity refers to an economic model that prioritizes the continuous use of resources by creating closed-loop systems where waste is minimized, and materials are reused, repaired, or recycled. This approach aims to decouple economic growth from resource consumption, fostering sustainability and reducing environmental impact.
Relevant Fields:
Concept
A circular economy is an economic system aimed at eliminating waste and the continual use of resources through principles like reuse, repair, refurbishment, and recycling. It contrasts with a traditional linear economy, which follows a 'take, make, dispose' model, by promoting sustainable practices that extend the lifecycle of products and materials.
Concept
Resource efficiency is the practice of using the Earth's limited resources in a sustainable manner while minimizing environmental impact and maximizing economic benefits. It involves optimizing the use of materials, energy, and water throughout the lifecycle of products and services to reduce waste and emissions.
Concept
Sustainability is the practice of meeting current needs without compromising the ability of future generations to meet theirs, emphasizing a balance between economic growth, environmental health, and social well-being. It involves adopting strategies and practices that promote resource efficiency, reduce waste, and support long-term ecological balance.
Concept
Waste management involves the collection, transportation, processing, recycling, and disposal of waste materials to minimize their impact on the environment and human health. Effective Waste management strategies are crucial for sustainable development and require the integration of technology, policy, and community engagement.
Concept
Life cycle assessment (LCA) is a systematic method for evaluating the environmental impacts associated with all stages of a product's life, from raw material extraction through to disposal. It provides a comprehensive framework to identify opportunities for environmental improvement and supports decision-making for sustainable development.
Concept
Industrial Ecology is an interdisciplinary framework for designing and operating industrial systems as living systems interdependent with natural ecosystems, aiming to optimize resource use and minimize environmental impacts. It emphasizes the closing of material loops and the symbiotic relationship between industries to create sustainable industrial processes.
Concept
Cradle to Cradle is a sustainable business and ecological design philosophy that encourages the creation of products with the full life cycle in mind, promoting innovation that supports human and environmental health. By envisioning a closed-loop system where waste serves as raw material, it aims to eliminate the concept of waste entirely and encourages continuous material reuse.
Concept
Concept
Product life extension involves strategies to prolong the useful life of products, thereby reducing waste and maximizing resource efficiency. This approach can significantly contribute to sustainability by delaying the need for resource-intensive manufacturing processes for new products.
Concept
Eco-design is an approach to product development that prioritizes environmental considerations throughout the entire lifecycle, from raw material extraction to disposal. It aims to minimize negative environmental impacts by integrating sustainable practices and materials without compromising on functionality or quality.
Concept
The Axiom of Foundation, also known as the Axiom of Regularity, is a principle in set theory that ensures no set can contain itself, establishing a well-founded hierarchy for sets. It prevents infinite descending chains of sets, facilitating a structured and non-circular understanding of set membership relationships.
Concept
Concentricity refers to the condition in which two or more circles or circular features share the same center point, ensuring uniform distribution and alignment around a central axis. This is crucial in engineering and manufacturing for ensuring precision and balance in components like gears, bearings, and rotating machinery parts.
Concept
Roundness is a geometric property that describes how closely the shape of an object resembles a perfect circle or sphere. It is a critical parameter in various fields, such as manufacturing and geology, where precision and natural formation analysis are essential.
Concept
Geometric tolerance is a system used in engineering and manufacturing to specify the allowable variation in form, profile, orientation, location, and run-out of a part's features. It ensures that parts fit and function together correctly, even when there are slight deviations from the exact dimensions.
