Why is Recycling Important?
Resource Conservation
Finite Resources: Many materials come from finite resources like metal ores, oil, and trees. Recycling reduces demand for virgin raw materials, preserves natural habitats from mining and extraction, and extends the lifespan of existing resources.
Energy Savings
Lower Energy Requirements: Recycling typically requires much less energy than producing from raw materials:
- Aluminum: 95% energy reduction vs. extraction from bauxite
- Steel: 60% energy reduction vs. making from iron ore
- Paper: 40% energy reduction vs. making from wood
- Glass: 30% energy reduction vs. making from sand/limestone
Waste Reduction
Landfill Diversion: Recycling reduces the amount of waste going to landfill. This reduces methane emissions from decomposing organic waste, preserves valuable land, and decreases the need for new landfill sites.
Greenhouse Gas Reduction
Climate Benefits: Lower energy use and reduced extraction means fewer emissions. Recycling 1 tonne of aluminium saves approximately 9 tonnes of CO₂. Less deforestation from reduced paper demand also preserves carbon-absorbing forests.
