At present, there are more than 2,600 restaurants in Sanya. The kitchen waste in Sanya has taken an increasing proportion in the living garbage with no less than 50 tons of kitchen waste daily produced.
The kitchen leftovers, thought to be a good source of digestible energy and high-quality proteins, often end up as feed for livestock such as pigs and chicken, as a supplement to their diet.
"We usually pay restaurants a few hundred yuan every month since they discharge more kitchen waste, " said Miss Lin, a kitchen waste collector living in Hailuo Village.
However, experts said kitchen leftovers were a source of infection for animals, which, in extreme cases, could result in contamination of meat or eggs and cause illness among people who consume livestock products.
Besides, many people still worry about this kitchen waste will be sold to the black market as cooking oil by some illegal processors due to the potential profits.
At present, the relevant department in Sanya is stepping up efforts to set up a kitchen waste treatment centre to handling the kitchen waste.
