The image of a woman carrying a reusable bag and some plastic containers has become familiar at a traditional market in Linh Nam Ward in Ha Noi’s Hoang Mai District. On average, each Vietnamese household uses around 1kg of nylon bags per month. More than 80 percent of these bags are discarded after single use, with a minimal proportion being properly processed. "I bring these plastic containers to hold various types of food when buying meat or fish instead of using single-use plastic bags given by the sellers", said Mrs. Nguyen Thi Hien, a 35-year-old woman from Nam Du Street.
