Major Australian recycling company SKM Recycling says millions of tonnes of recyclables are destined for landfill if it collapses, warning of a "major crisis" if China stops recycling Australian waste.

SKM Recycling, which is contracted to more than 30 Victorian councils, is facing liquidation as creditors claim they are owed millions of dollars. 

The company has warned the Government there is the potential for an additional 400,000 megatonnes of recyclables being sent to landfill per year if the major recycler ceases business.
