Review Questions

• How does raw material extraction impact the sustainability of nanomaterials?
  • Raw material extraction plays a critical role in the sustainability of nanomaterials by determining how resources are obtained and their environmental consequences. Unsustainable practices can lead to depletion of resources and ecological harm, while responsible extraction methods can promote conservation and sustainable use. The balance between obtaining necessary materials for nanotechnology applications and maintaining ecological integrity is essential for achieving long-term sustainability.
• Discuss how life cycle assessments can be used to evaluate the effects of raw material extraction on nanomaterials.
  • Life cycle assessments (LCA) provide a comprehensive framework to evaluate the environmental impacts associated with raw material extraction for nanomaterials. By analyzing each stage from extraction through production, use, and disposal, LCA helps identify areas where improvements can be made. This process highlights potential negative effects such as energy consumption, emissions, and waste generation resulting from extraction methods, guiding stakeholders towards more sustainable practices.
• Evaluate the ethical implications of raw material extraction in the context of developing new nanotechnology applications.
  • The ethical implications of raw material extraction in nanotechnology development involve several dimensions including environmental justice, resource equity, and social responsibility. Evaluating these aspects reveals how certain communities may suffer from environmental degradation due to extractive industries while others benefit from technological advancements. Moreover, addressing issues such as labor rights, fair trade practices, and transparency in supply chains is crucial to ensure that raw material extraction contributes positively to society while supporting innovations in nanotechnology.
