While we produce about four billion tonnes of food annually, it is estimated that 30-50% of this never reaches our plates. Of the food that does reach us, some western societies throw away up to a third of all food purchased. This has enormous implications for the global environment, from wasting the water used to grow the food to adverse effects on climate, land and biodiversity. The drivers behind these phenomenal levels of food waste are complex and include food pricing, logistical and storage issues.
There is an urgent need for legislation to enforce separate food waste collections, not only to ensure it was diverted to anaerobic digestion or composting, but also as it led to greater self awareness around food waste.
