Farmer floats idea for shipping container grain storage

Grain Central, November 21, 2016

FACED with a shortage of storage space in local silos and a surplus of low-value grain, a southern Queensland livestock and cropping farmer is exploring the novel solution of setting up a home-grown, on-farm grain storage facility using shipping containers.

Queensland farmer, Charles Nason, believes 20-foot shipping containers like this, stood on their ends, could make effective on-farm storage facilities.

Queensland farmer, Charles Nason, believes 20-foot shipping containers like this, stood on their ends, could make effective on-farm storage facilities.

Charles Nason hit upon the idea of standing 20-foot shipping containers on their ends to create a simple, cost-effective way of storing the grain on his Roma farm Banoona in a season when other options have become limited.

“I was going to deliver barley to Roma but, because there were no deliveries of barley, the decision was made by GrainCcorp to use the shed for wheat,” he said.

“Most if not all of the few depots accepting barley east of here are full or near full so there are very few options to deliver.”

Mr Nason considered a number of other on-farm storage alternatives:

– Silo bags: “good short term option but pigs, mice and birds are an ongoing threat”;

– Pads: “similar to silo bags – constant supervision required”;

– Silos: “all manufacturers booked out till next year”;

– Mesh silos: “mesh is no longer available”;

– Hole in the ground, possibly lined and covered: “getting grain back out may be an issue”.

So, the idea of using 20-foot ‘bulka’ containers that could be stood on their ends and filled through a hatch in the top may be the answer Mr Nason has been looking for.

“Containers are sealable so that solves the weevil issue and thus can be permanent storage,” he said.

“If you had a 40ft container you would need an 80ft auger, so you are realistically restricted to a 20ft container to stand up.

“It would need some modifications to fill, empty and access. Before you fill it up you must cut an access hatch in the bottom so you can get an auger in to unload it.”

Mr Nason said a 20ft container was about two-thirds the price of a 40ft, so the cost per tonne of storing grain would be higher with the smaller container.

“A 20 ft ‘bulka’ container would only be about 80pc fillable. A 20ft holds 35 tonnes and a 40ft holds 70t, assuming it is full when upended.

“Normal silos are about $200 per tonne to store grain but a ‘bulka’ container – at a cost of $3500 divided by, say, 30 tonnes when 85 per cent full – is about $120 per tonne, plus freight.”

Mr Nason said with cattle worth feeding, many cattle producers were considering ways to store cheap wheat, barley, oats, and even downgraded pulses.

“Most do not have storage, but containers offer a cheaper and more available option to silos,” he said.

He said a limitation of the container concept, apart from the need to have an auger, was that producers would need access to a crane to stand the containers on their ends.

    Yes, a difficult year to have the additional on-farm storage required. Just a thought regarding the comment … “containers are sealable so that solves the weevil issue”. Most older shipping containers are not “gas-tight”, due to gas leakage through the floor, damaged walls, vents and particularly gas leakage around the doors seals. So if you plan to fumigate, carry out repairs and modifications that give you confidence the container is actually going to be sealable, “gas tight” for an effective fumigation. Great to see new ideas put forward, well done. As always, be extra careful with safety when trying new ideas.
