STOMPer Irene is frustrated with the smoke emitted from the refinery at Johor, as she says this causes serious air pollution.
Says the STOMPer:
"There is serious air pollution in Punngol due to the refinery at Johor.
"It is pollution, day and night, for us Punggol residents."
STOMP found that it is standard practice for refineries to release exhaust gases to protect pipes from over-pressurisation. This controlled burning of waste gases is known as 'flaring' and the resulting smoke is a mixture of water and carbon dioxide.
