Grain silo bag circular economy feasibility study

Grain silo bags are made from multi-laminate LDPE plastic and used by grain farmers to temporarily ‘bulk’ store harvested grain (e.g. Up to 300 tonnes in each bag). These bags can be 3m in width, up to 100m long and weigh as much as 180kg (of plastic material).

There are no local manufacturers of the bags with all bags being imported from overseas, and currently the bags are not recycled by grain farmers – but there is growing pressure for this to change. 

This Grain Silo Bag Circular Economy Feasibility Study and Report was commissioned by Grain Producers SA to find a Circular Economy recycling solution to disposal of waste plastic grain silo bags.

This study was supported with funding from Green Industries SA's Circular Economy Market Development Grant program.
