Storage project

Sustainable storage solutions for South America

t Milling and Grain we are always looking for innovative and sustainable storage solutions to champion. We are forever reminded that by 2050 the global population will have risen to over nine billion people, with this in mind durable storage solutions are vital for ensuing food supplies are kept safely and that farmers and distributors can get the highest value from each crop yield, simultaneously decreasing waste and increasing the economic worth. Argentinian silo bag producers Ipesa are no strangers to such innovation; they have announced that they will be sending two representatives to attend Sustainable Intensification 2016 in Rio de Janeiro, with a view to provide upwards of 900,000 farms across Brazil with their silo bags, and to further discuss storage concerns with farmers and distributors. Ipesa have addressed the need for an inexpensive, yet viable alternative to steel silos, the silo bags not only boast a decent capacity – averaging 200 tonnes in the standard 9 ft by 200 ft silo bag – but the low cost and ease of maintenance essentially allows the farmers to regain control of their crop. The good quality yield, low maintenance, control and good economics of the silo bag means they can be hailed as the practical solution to crop storage problems. We spoke to Juan Martin Dedeu, Ipesa’s Commercial Manager, about the benefits of the silo bag system above the more traditional steel silo. 78 | April 2016 - Milling and Grain

The hermetic ‘air tight’ system

Firstly, he revealed the difference in the way in which the grain is stored. The grain within the silo bags is stored in a hermetic ‘air tight’ system; where as the grain in the steel silos are stored in an atmosphere with air circulation. Mr Dedeu told Milling and Grain, “The main difference between both storage systems is that in the steel silo the grain is stored in an atmosphere with air circulation and in the silo bags it is a modified atmosphere an air tight system – a hermetic system. The grain consumes oxygen and gives off

carbon dioxide when inside the hermetic bag – in this modified atmosphere insects and fungus, starved of oxygen, cannot grow – the grain is dormant and will be kept in that condition until you open the bag. The lack of oxygen and high level of carbon dioxide will kill
