Life Cycle Assessment

Definition

Life Cycle Assessment (LCA) is a systematic process for evaluating the environmental impacts of a product or material throughout its entire life cycle, from raw material extraction to production, use, and disposal. This comprehensive approach helps identify opportunities for reducing negative impacts and promotes sustainable practices in various industries, particularly in the context of nanotechnology.

5 Must Know Facts For Your Next Test

1. LCA provides a framework for assessing the environmental impacts associated with each stage of a product's life, helping businesses make informed decisions about materials and processes.
2. In nanotechnology, LCA can uncover specific environmental risks and benefits related to the use of nanomaterials, which may behave differently than conventional materials.
3. LCA results can influence regulatory frameworks by highlighting the need for guidelines that ensure safe and sustainable development of nanotechnology applications.
4. Conducting LCA can help companies identify cost-saving opportunities by optimizing resource use and reducing waste throughout the production process.
5. The application of LCA in nanotechnology is crucial for promoting sustainable innovation, as it encourages responsible choices in material selection and product design.

Review Questions
