Changing fixed patterns of thinking: finding a replacement for EPS foam
At IKEA we believe that being big comes with a responsibility. That is why we decided to develop a more sustainable packaging solution than the widely used EPS foam, in hope that our initiative will drive the home furnishing industry towards better packaging solutions.
Expanded polystyrene (EPS) foam has been extensively used all around the world for many years. It is a cheap, durable, lightweight and easy to form material. But it is also an oil-based product that is often not recyclable on an industrial scale. EPS foam often ends up in nature where it is not degradable, instead atomizing into small parts which are possibly harmful to humans and animals.
Still, there was a big resistance regarding phasing out EPS foam packaging, both internally and at many suppliers. It was hard to grasp why IKEA should replace a material with many good qualities that had been used for a long time. To convince the skeptics, we set out to develop a new recyclable material that was equally as cheap and easy to use as EPS foam.
Applying existing solutions to a new context
Together with many co-workers and suppliers IKEA began a journey to find a new and better packaging solution. The material selected had to be cheap, possible to recycle many times and compatible with the recycling systems used by most countries today. IKEA solved this by using fiber-based materials like corrugated paper and molded paper for the new packaging solution.
To keep the durable and lightweight properties of the EPS foam, IKEA decided to use a honeycomb construction made of the fiber-based materials. A honeycomb is a mass of hexagonal cells inspired by the constructions built by honey bees to contain larvae and store honey. It has been used by IKEA for many years as a core material in things like doors and board based products. The turning point in the development process was the realization that the honeycomb construction could be used in a different context. It could be used as a recyclable shock absorber in the new packaging solution; making it light, yet strong.
Replacing EPS
It took four years to phase out EPS foam in almost all IKEA flat packs and replace it with the new recyclable packaging solution. The change from EPS foam to fiber-based materials means that IKEA has reduced the use of EPS foam by 8000 tons per year. This equals more than half the volume of the Empire State Building. The decision to change filling material in IKEA flat packs is valid for all packaging except for appliances. At the moment IKEA is too small in this segment to be able to affect the global industry.
“We are working on a more sustainable solution even within this field. Phasing out EPS foam is a step towards changing the packaging solutions throughout the home furnishing industry and making them more sustainable,” says Peter S Larsson, Packaging Sustainability Leader at IKEA of Sweden.
