The wood is used for temporary construction, packing cases, concrete shuttering and similar uses. In the Philippines it is also used for house construction, particularly for sides, ceilings and partitions. The wood is stronger and more durable than most other Sterculia wood. The seeds are eaten as nuts (although they may be slightly poisonous when fresh), and they are the source of an oil which is used for illuminating and painting. The flowers and leaves have medicinal value. The trees are planted for shade, and sometimes used as stakes for sirih ( Piper betle L.). The rind of the fruit was formerly used in dyeing baths for batik.

S. foetida occurs in primary and secondary forest, often on river banks and on coral sandstone rocks along the coast, up to 1000 m altitude. The heartwood is pinkish and has a pungent smell. The density is 495-600(-760) kg/m3at 15% moisture content.
