Study Notes

Need for Sustainability

Population growth leads to environmental degradation through over-exploitation of resources.
Sustainable development is essential to restore and protect the ecosystem from environmental degradation.

Sustainable Civilization

Sustainable civilization incorporates principles that ensure balance between economic growth, social well-being, and environmental protection.
It's a shift from exploiting natural resources to managing them responsibly for future generations.

Three Dimensions of Sustainability

Environmental, economic, and social aspects are interconnected and crucial for sustainable development.

Sustainable Development: Decision Making

Decision-making should consider environmental, economic, and social impacts, balancing resource use with sustainable practices.

Sustainability: Problems

Current unsustainable practices threaten the planet's resources and the well-being of people.

6Rs Principles

Reduce, Reuse, Recycle, Refurbish, Redesign, and Remanufacture are key principles for driving resource efficiency.

Circular Economy

Circular economy focuses on restorative and regenerative principles, emphasizing closed-loop systems that minimize waste and maximize resource utilization.

Sustainable Development Goals (SDGs)

Global goals adopted by the UN in 2015 aim to eradicate poverty, protect the environment, and ensure prosperity for all by 2030.
The 17 SDGs are interconnected, meaning actions in one area impact others.

Cleaner Production (CP)

A tool to achieve SDGs, CP aims to minimize environmental impact throughout production processes.

Industry 4.0
