Thanks for the support from ECF plastic recycle center of TKO and WTS. We send compactor truck weekly to their center to pick up plastic bottles. Since Hong Kong has high land and labor cost, there is no reasonable to perform sorting and baling in urban area. Therefore, we use compactor truck to pick up around 50,000 bottles each time ( 1.5 metric ton ) back to factory in N.T. Then we use optical sorting machine to sort the plastic bottles.
