State four waste minimization techniques.

1. Source reduction: This involves reducing the amount of waste generated at the source by using less material or finding alternative materials that generate less waste.

2. Recycling: Recycling involves collecting and processing materials that would otherwise be thrown away and turning them into new products. This helps to reduce the amount of waste that ends up in landfills.

3. Composting: Composting organic waste, such as food scraps and yard waste, can help reduce the amount of waste sent to landfills. Composting also produces nutrient-rich soil that can be used in gardening and landscaping.

4. Reuse: Reusing items instead of throwing them away can help minimize waste. This can involve repairing items, donating them to others in need, or finding creative ways to repurpose them for a different use.

1. Source reduction: Reducing the amount of waste generated at the source, such as using reusable products, reducing packaging, and designing products for durability.
2. Recycling: Processing and transforming waste materials into usable materials, such as recycling paper, plastic, and metal.
3. Composting: Decomposing organic waste, such as food scraps and yard waste, into a nutrient-rich soil amendment.
4. Energy recovery: Incinerating or gasifying waste to generate energy, such as electricity or heat.
