The packaging industry is still the biggest purchaser of plastic products, accounting for almost 40 per cent. However, large producers and retail chains have long since begun to rethink their packaging policies and aim for more recycling. The research group Chemie und Verfahrenstechnik von Verbundwerkstoffen (chemistry and process engineering of composite materials) at the Faculty of Forest Sciences and Forest Ecology at Göttingen University has now succeeded in developing a novel process, based on its many years of experience in the field of renewable raw materials. The results are that three-dimensional moulded forms can be produced from “granulated” popcorn. The great advantage of this granular material is that it comes from renewable biological sources, is environmentally friendly and sustainable. It is therefore an excellent alternative to the polystyrene products used previously.
"This new process, based on technology developed in the plastic industry, enables the production of a wide range of moulded parts," explains the head of the research group, Professor Alireza Kharazipour. "This is particularly important when considering packaging because it ensures that products are transported safely which minimises waste. And this has all been achieved using a material that will even be biodegradable afterwards." In addition, the new popcorn products have water-repellent properties, which opens up new avenues for future applications.

Stefan Schult, Managing Director of Nordgetreide, which holds an exclusive licence, adds: "Each and every day we pollute our Earth with an ever increasing amount of plastic waste that will be a burden on our eco-system for thousands of years. Our popcorn packaging is a great sustainable alternative to polystyrene which is derived from petroleum. The plant-based packaging is made from the inedible by-products of Cornflakes production and can actually be composted after use without any residue."
The licensing agreement for the packaging sector was brokered by MBM ScienceBridge GmbH, a wholly owned subsidiary of the University of Göttingen Public Law Foundation. According to Dr. Jens-Peter Horst, CEO of MBM ScienceBridge GmbH, this agreement is exemplary for the successful transfer of innovative, academic research with a high impact on a sustainable transformation of the packaging industry.

Nordgetreide GmbH & Co. KG is a medium-sized company with a presence throughout Europe and many years of expertise in the efficient processing of maize, wheat, barley and rice.
