Early packaging

In prehistoric times, leaves, animal skins or gourds were used to store and transport items. A little later, clay pots and straw baskets were used. In about 2500 BCE, the Egyptians invented glass. It was expensive, so only the rich could use it. They learned how to blow glass to make jars. Around 100 CE, paper was developed in China. This is the oldest example of flexible packaging. Chinese people used paper to wrap medicine and make parcels of tea. In the 1300s, wooden barrels became popular for transporting water and dried foods.

• How were these packaging materials used?

• Why was paper special?

• Who invented glass and paper?

Why are clothes so hard to recycle?

Most recycled bres that are used for clothing come from old bottle tops, not old clothes. Why is that? Most clothes are a mix of yarns and accessories. Even a T-shirt that is 100% cotton contains threads, dyes and labels that are made from di erent materials. Labels, zips and buttons must be separated. is makes the process of sorting clothing slow and di cult. It needs skilled people or specialised equipment to identify the di erent materials. Only 1% of our clothes are currently recycled into new textiles. Scientists are experimenting with other ways to use the bres from clothes, including using it to make glue and building materials. ey are also trying to make all material for clothing more sustainable.

4 Use the Top tips to write a research question that will help you to find solutions for sorting textiles for recycling.
