There is a growing awareness in Western industrial nations of the continuing problem of food waste. Restaurants offer to wrap up leftover food or cook meals using ingredients that are close to their use-by date. Consumers are now also more willing to buy less attractive looking fruit and vegetables, and thereby avoid goods being simply thrown away. In other areas, the issue of waste prevention is also becoming more important. People are now increasingly questioning the sense of so much plastic packaging. The first supermarkets have started selling unpackaged goods in large containers to customers who bring their own forms of packaging with them.
