The United Nations Sustainable Development Goals (SDGs) are a collection of 17 global goals designed to be a "blueprint to achieve a better and more sustainable future for all." Chemistry plays a crucial role in achieving many of these goals.
Detailed Explanation
The Sustainable Development Goals (SDGs) were established by the United Nations as a universal call to action to end poverty, protect the planet, and ensure prosperity by 2030. These goals serve as a framework that nations and organizations can use to orient their efforts and policies toward sustainable development. Chemistry significantly contributes to these goals by providing solutions in various areas like health, energy, and environment.
Examples & Analogies
Imagine a community approaching a problem like pollution. The SDGs act like a community map that shows everyone where to direct their efforts. Just as a community might mobilize resources to clean up pollution or improve education, chemistry intersects with these goals by offering scientific solutions to make clean water, better health, and green energy possible.
Chemistry's Role in Clean Water and Sanitation

โ SDG 6: Clean Water and Sanitation:
- Chemistry is vital for water purification (e.g., chlorination to kill bacteria, chemical coagulation/flocculation to remove suspended particles, advanced membrane technologies for desalination and removal of microscopic pollutants).
- It's also involved in wastewater treatment, breaking down pollutants before water is returned to the environment.
- Understanding the chemistry of pollutants (like heavy metals, organic compounds) is essential for detecting and removing them.
Detailed Explanation
SDG 6 focuses on ensuring availability and sustainable management of water and sanitation for all. Chemistry contributes significantly to this goal by providing methods to purify water. For instance, chlorination involves adding chlorine to water to kill harmful bacteria, and coagulation helps remove particles that cloud the water. By understanding the chemical nature of pollutants, chemists can develop effective systems to treat waste and ensure that only clean water is released back into nature.
Examples & Analogies
Think of chemistry's role in water purification like a filter for a pitcher of water. Just as the filter cleans out impurities, chemical processes in water treatment remove harmful elements, ensuring the water we use for drinking and bathing is safe and clean.

โ SDG 7: Affordable and Clean Energy:
- Chemistry is central to developing renewable energy technologies:
- Solar Cells: Chemical processes are used to manufacture silicon and other materials for photovoltaic cells that convert sunlight into electricity.
- Batteries: Advanced battery chemistry (e.g., lithium-ion, solid-state batteries) is crucial for storing intermittent renewable energy (solar, wind) and powering electric vehicles.
- Hydrogen Fuel Cells: Chemical reactions between hydrogen and oxygen in fuel cells produce electricity with water as the only by-product.
- Biofuels: Chemical conversion of biomass (plants, algae) into liquid or gaseous fuels.
Detailed Explanation
SDG 7 aims to ensure access to affordable, reliable, sustainable, and modern energy for all. Chemistry plays a pivotal role in developing technologies that harness renewable energy sources. For example, solar panels rely on chemical processes to convert sunlight into usable energy. Similarly, batteries made with sophisticated chemistry can store this energy for later use, while hydrogen fuel cells generate energy by combining hydrogen and oxygen, creating only water as a by-product. These innovations help reduce reliance on fossil fuels and lower carbon emissions.
Examples & Analogies
Imagine charging your phone. Just as your device needs a connection to a power source, the energy industry needs new ways to 'charge' our society sustainably. Chemistry acts like a technician enabling various energy sourcesโlike sunlight and windโto be harnessed efficiently and stored safely, helping keep our devices powered without harming the planet.
