Tuas is a largely industrial zone located in the west of Singapore. The Malaysia-Singapore Second Link that links Singapore and Malaysia is also located there.

It is largely reclaimed land, the purpose at the time for a site to build industry during the same time Jurong was being built up. It is also quite far away from residential area and especially far away from the main commerical district of Singapore. This was the main reason it was chosen to site industry and therefore some semblance of heavy industry can be found in Tuas, although not as much as Jurong Island. For this reason of being far away from commerical and residential areas, two of Singapore's four incinerators are found in Tuas, namely Tuas Incinerator and Tuas South Incinerator.
