There are also some cities and counties that leave recyclable materials unsorted (kitchen scraps excepted), auctioning off entire batches to reduce manpower costs. The Taipei City Government began doing this in 2002, adding revenues of NT $ 60-70 million a year to the city treasury.
也有些縣市對資源回收物（不含廚餘）並不分類整理，而是全部統一標售以節省內部人力設備成本，如台北市 2002 年之後就採取這種作法，每年依舊能為市庫創造 6、7 千萬元的鉅額收入。
