Greenhouse Gas Advantage (Steel Pallet)

How does a lightweight steel pallet compare against any plastic pallet on the Co2 carbon dioxide emissions factor?  (With acknowledgement)

A 25 Kg plastic pallet from anywhere costs about 150 Kg of greenhouse gas to produce because approximately 6 Kg of Co2  is produced to make 1 Kg of HDPE.  This does not include additional Co2 cost of any embedded steel.

It takes about 2.88 Kg of coal to produce 1 Kg of steel.  An equivalent lightweight steel pallet costs about 72 Kg of greenhouse gas, HALF that of plastic.  The steel in this case is less than 1mm thick.

Steel Wins.
