Kitchen waste for pigs included rice, noodles, beans, snacks, flour food, canned food and flavoring which the pigs could eat.

Kitchen waste would be sold to pig farmers by the public tender. The sanitation team collected kitchen waste and delivered to the collecting center every evening, and the pig farmers would come to get in the next day. For the sake of safety, kitchen waste had been heated with high temperature of 950C for more than one hour and fed pigs afterwards.

In order to understand the using situation of kitchen waste, we visited Refu farm in Zhongli.
Mr. Zeng, the owner of farm, said that since kitchen waste of Taipei was divided into for compost and for pigs, the quality was better than the others. There were 18 farms attending the tender this year. The competition was intense. The price of one bucket had been raised from 60 NTD to 260 NTD.
Kitchen waste was used to feed black pigs. If one pig had eaten five kilograms of kitchen waste, it would grow one kilogram of meat. Moreover, if the pigs ate kitchen waste, they would have better resistance against diseases because kitchen waste included a lot of acid substances.
Owner Zeng said that when cooking kitchen waste, there was a coat of oil which would be the best material of making Bio-Diesel.

After visiting the farm, we found the excrement of pigs could be the natural compost. And after sewage treatment, the excrement water could be so clean that we could use it to wash hands, Mr. Zeng said.
Most citizens did not know how to distinguish kitchen waste “for compost” from “for pigs”. They always made them as for compost, so the recycling ratio of “for compost” to “for pigs” was 8:2.
Now TDEP brought up the idea of “can’t be eaten is for compost, can be eaten is for pigs”. In other words, the idea of “may eat or not” was the judgment standard. They hoped to raise the recycling ratio of kitchen waste for pigs.
