BASF has won an order to supply diesel particulate filters for over 2,500 Hong Kong transit buses, marking the first large-scale commercial use of diesel particulate filters in the city as part of a diesel retrofit program.
Beginning in spring 2008, BASF’s DPX Max filters will be installed on vehicles from Hong Kong’s four major transit bus operators - Kowloon Motor Bus, Citybus, New World First Bus Services and New Lantao Bus.
BASF’s DPX technology has already been proven on tens of thousands of trucks and buses, and earned the first US Environmental Protection Agency Urban Bus Retrofit certificate.
Kane Shum, principal engineer for KMB, and Paul Li, head of operations and engineering for CTB and NWST, said that they conducted extensive field trials before choosing the filters, which can cut emissions of particulate matter, or soot, by more than 85 per cent.
Diesel vehicles are the main cause of street-level air pollution in Hong Kong. Hence the Hong Kong government has instituted a number of initiatives to combat the problem, including the diesel retrofit program aimed at reducing emissions.
BASF Catalyst’s distributor in Hong Kong, Consolidated Parts and Accessories Sales Centre (a member of Dah Chong Hong Holdings), will supply the filters for the buses and provide maintenance services.
