Study Notes
- Sustainability meets present resource needs without harming the environment or compromising future generations. It balances nature and making beneficial choices for people and the planet.
Pillars of Sustainability
- Economic sustainability supports long-term financial growth while considering environmental, community, and social factors.
- Social sustainability ensures the well-being of people and communities by promoting equity, human rights, access to education and healthcare, and decent work. Focus on positive social impacts of actions and systems on individuals and society. It emphasizes "putting people first" in development.
- Environmental sustainability uses natural resources responsibly to meet current needs while preserving the environment for future generations.
Material Extraction Considerations
- Aerospace materials like titanium and rare earth elements are found in limited quantities. Over-extraction depletes these materials, impacting future generations.
- Mining and extraction damage the environment via habitat destruction, biodiversity loss, soil erosion and contamination, water pollution, and air pollution.
- Extraction in remote areas endangers local communities by pollution, disrupting livelihoods, health risks, and damage to the local ecosystem.
Manufacturing and Fabrication Considerations
- Manufacturing and metal fabrication are very energy-intensive processes, which contributes to greenhouse gas emissions. Efficient manufacturing techniques can reduce energy use.
- Traditional manufacturing generates waste like material scraps, off-cuts, and chemical byproducts. Optimized designs and manufacturing processes are essential to minimize waste.
Launch and Operations Considerations
- Aircraft and spacecraft require vast fuel amounts, causing significant greenhouse gas emissions and air pollution. Improving fuel efficiency is a major focus.
- Lightweight materials reduce fuel needs, aerodynamic design optimizes flight, and alternative fuels are being explored to increase fuel efficiency.
- Space debris is created when launching spacecraft, so sustainable launch practices and debris mitigation strategies are necessary.
