Sydney City Council recently decided that the best way to stop trucks backing into bins and containers at a storage depot was to put in a pair of 125 x 125mm  bollards. Simple but effective, the bollards do their job as a safety barricade. And being made of recycled plastic they will continue to stand tall for years to come, whatever the ground conditions. The material in each bollard is equivalent to 2500 plastic bags saved from  landfill.
