On 1st April, the team of Project CFL in Chengdu and Gudrun Zecha, representative of BOKU, went to Xingrong Hazardous Waste Treatment Co. Ltd. and conducted WFL break experiment there. By imitating the usage of collection boxes in daily condition, they tested the break percentage during WFL disposal, in order to assess the anti-break ability of the collection boxes. According to the experiment, the collection boxes made by Chengdu team achieved a zero break result, which approved the rationality of the design of the collection boxes. The collection boxes used in Chengdu was made by pasteboard with anti-break baffles in the opening, referring to the design of WFL collectors in EU.
