A green group is urging manufacturers to take responsibility for the problem Mooncakes are not only bad for your health it also appears they are a hazard to the environment. Green group Friends of the Earth estimates that more than three million mooncake tins, weighing more than 750 tonnes, are dumped into landfills every year. And this means that Hong Kong taxpayers have to spend about $620,000 to dispose of them, the organisation's director, Mei Ng, said yesterday. 'However, if those wasted tins could be recovered and recycled it could earn $150,000 and save the metal waste from our landfills,' said Ms Ing. 'We will launch a 'Moon-kick Action' to urge cake manufacturers to take up their recycling and waste-reduction responsibilities. 'Producers taking back their own packaging waste would not only help to reduce waste but also boost their corporate integrity.' Friends of the Earth recently contacted five of the largest mooncake manufacturers and was told that none of them had any plans to recycle the tin boxes. A survey by Chinese University in which 1,033 people were interviewed found that 66.1 per cent would return their empty boxes if the producers were willing to recycle them. And half of the respondents said they thought manufacturers had the biggest responsibility to recycle used products. Legislator Choy So-yuk, who is the chairwoman of the panel on environmental affairs in the Legislative Council, has written a letter to Hong Kong's largest mooncake manufacturer, Maxim's Group, to highlight the responsibility of producers on this issue. However the bakery, which runs more than 300 shops in Hong Kong, had made no commitment to a recycling programme, according to the spokesman. 'It's a natural response [of Maxim's] as there are no rules in Hong Kong to enforce producers' responsibility,' he said. The group suggested that cake producers issue a cash coupon for every returned tin box in order to encourage consumers to recycle.
