To Kau Wan

To Kau Wan (Chinese: 倒扣灣) is a bay on the north shore of northeast Lantau Island, Hong Kong. Contaminated soil from Penny's Bay was transferred here for thermal desorption to separate the volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) along with cement immobilization of metal contamination from Penny's Bay. The oily residue was transferred to the Chemical Waste Treatment Center in Tsing Yi for incineration (particularly for dioxins and dioxin-like compounds).^{[citation needed]}
