Oil refinery greenhouses CO2 pipeline

A project to reduce the carbon dioxide emissions from oil refineries by using the gas as "fertiliser" in commercial greenhouses has been so successful it is being extended. The project, which adds new meaning to the term "greenhouse gas", is the first in the world. It distributes CO2 from Shell's Pernis refinery outside Rotterdam to 400 greenhouses, saving a large amount of natural gas each year, which is equivalent to 170,000 tonnes of CO2. » original news
