Come April 1 and a landmark pay-as-you-throw scheme aimed at reducing waste kicks off following many months of waiting. The Municipal Solid Waste Charging Scheme has been passed for awhile and its implementation is overdue, given the amount of waste disposed at landfills each year. Environment Secretary Tse Chin-wan and his predecessor who initiated the charging scheme knew it would need the public to change their habits. First, do these cleaning workers need to check whether all the bags in an estate's storage areas are legal - that is, government designated bags purchased from approved outlets? Unless it is better clarified, April 1 could turn out to be April Fool's Day for those serving in the frontline.
