A survey of shoppers has found more than 70 per cent believe some food packaging is unnecessary, while a green group says more than 80 per cent of snacks sold in the city's supermarkets are overpackaged. Greeners Action, which sampled 117 commonly available snacks in supermarkets in September, considered 96 to be overpackaged. These products, including biscuits, chocolates, chips and candies, contained 'redundant' individual packaging, the group's executive director, Angus Ho Hon-wai, said. 'For example, in a pack of 100 biscuits, the biscuits are wrapped separately in batches of three or four, and a plastic plate is also supplied,' he said. The group, which polled 898 shoppers outside supermarkets, found only 14 per cent prefer to buy products with individual packaging. Seventy-six per cent said they threw away packaging immediately, and only 6 per cent said they recycled it. 'It proves that the manufacturers are causing unnecessary wastage,' Ho said. The group urged manufacturers to use simple packaging that would do less damage to the environment. Ho said that of the 23 companies they sent their petition to, only five had responded. 'Not one of them wanted to change their existing policy,' he said. 'Some cited hygiene reasons, some said snacks can be kept longer in individual packages.' But Ho said these explanations did not stand up to scrutiny because the same companies were also producing family-sized snacks with just one layer of packaging - which he recommended shoppers buy. He said shoppers could store the snacks in plastic boxes or reusable bags when they could not finish the whole pack. According to statistics from the Environmental Protection Department in 2008, Hong Kong disposes of 9,453 tonnes of solid waste per day, of which 20 per cent, or 2,000 tonnes, is packaging, including food and drinks packaging.
