Food supply chains are usually linear. This means food moves in one direction, from the field where it is grown (start) to the plate where it is eaten (end) with waste generated at all the different steps along the way.
1. POTATOES Annual waste in British households: 5.8 million whole potatoes
2. BREAD Annual waste in British households: 24 million slices of bread
3. MILK Annual waste in British households: 5.8 million glasses of milk
4. BANANAS Annual waste in British households: 1.4 million edible bananas
5. SALAD Annual waste in British households: 178 million bags of salad

The Reducing Food Waste at Home bitesize course from Zero Waste Scotland is designed to give users a comprehensive understanding of food waste and why it matters in as little as 15 minutes.
A circular economy is a system that operates in a circular way rather than in a straight line. There is no waste because any ‘waste’ or ‘by-product’ is used as a product in the system.
The purpose of food production is to feed people. We need to eat all the food we produce including the wonky fruit and veg.
If the food can’t be eaten by people for example orange peels, it should feed livestock, fish and insects, which we can then eat as a source of protein. The animal poo can then go back into the soil to help fertilise new crops. Any food not suitable for feeding animals should be composted and then returned to the soil to help grow more food.
Moving to a circular production system reduces waste and increases profitability for the farmer.

Wool demonstrates the circular economy in action perfectly. Wool is produced by sheep every year removing and storing carbon from the atmosphere. As wool grows on the sheep each year it is a renewable resource, wool products are long lasting and the fibre is biodegradable meaning wool can be returned to the soil, helping new grass to grow, to feed more sheep and produce more wool.
Wool can also support biodiversity where the sheep are managed well and wool products don’t shed any micro plastics.
In contrast, synthetic fibres like polyester are made from non-renewable fossil fuels, they produce carbon during their production and they shed micro plastics throughout their lifespan. Synthetic material clothing also tend to have shorter lifespans than wool products – they are kept for shorter times and washed more frequently.
