2.3.1 Recyclable products Glass Plastic Metals
2.3.2 Products that use recycled materials
2.3.3 Disassembly Tertiary recycling
2.3.4 Types of recycling Primary Same as reusing a product eg. refilling plastic bottle Secondary Taking something apart and making something else eg. making a pair of jeans into a bag Tertiary When products are broken down and reformulated eg. plastic bottles into fleece fabric
2.4 Rethink
2.4.1 Is it possible to approach design problems differently? More sustainably? How?
