Last month's scandal over sales of tainted lard from Taiwan has been a source of bitter satisfaction for Hong Kong's handful of biodiesel producers. It's helped shine a spotlight on a warped market that encourages restaurants and catering operations to sell used cooking oil at higher prices to unscrupulous dealers, only to have it return to local kitchens in the form of lard or other oil and fat mixed with "gutter oil".
The choice is obvious when recyclers are offering commercial kitchens as much as HK$91 for a 15 kilogram barrel of used cooking oil, says Steve Choi Sau-yim, executive director of biodiesel company Dynamic Progress International.
