In the suburb of Hanoi, the collection of food waste for feeding pigs has been practice for many years. Food waste is collected from restaurants, resident zones in the city within the distance of 10 to 15 km. Farmers pay for food waste from 200,000 – 300,000 up to 500,000 VND/year for restaurants or even 2 - 4 million VND per month for big restaurants and hotels. Food waste is sorted and cooked, and then mixed with concentrates or maize/cassava meal. According to farmers, feeding pigs using food waste could avoid the pressure from increase in the feed cost, and therefore, the benefit increased. However, this method is more suitable with medium scale production. A farmer who kept 200 pigs said that he could save 60% on feed costs from using food waste.
