From idea to innovation

A sturdier film to hold dry horse feed, plastic film instead of net around silage bales to maintain the fodder’s nutrient content and a handbook that shows the preservation process in bales – these innovations might never have seen the light of day, if it had not been for the collaboration between Trioplast and the Swedish University of Agricultural Sciences, SLU.

Our collaboration with Trioplast has been running since the 1970s, but it was perhaps around 2000 when the Field Science Network was started by a number of international companies, including Trioplast, that cooperation became more organized,” says Rolf Spörndly. He is a research director at the Department of Animal Nutrition and Management at SLU, and a guru in his field. Developing innovative ideas for new smart products and solutions has always been high on Trioplast’s agenda.

Among other things, SLU performs stretch film trials on bale ensilage for Trioplast. The anonymized tests are conducted in real-life environments in the fields of one of the many farms designated for research and trials within SLU’s operations. The tests on silage bales and the various plastic grades are performed over a period of 3-12 months. SLU researchers measure, among other things, possible weight losses and chemical changes, check the density of the plastic and make visual inspections to see if there is mould on the lining. “Using this approach, Trioplast can then show scientifically and statistically reliable results from lab analyses. These are impartial results presented by our researchers that show how well the plastic ensures that the feed value is as high as possible,” says Rolf Spörndly.
