The packaging industry is now more than ever craving material solutions that will have an actual positive impact on issues relating to resource deficit, waste, and pollution. All issues important to tackle and which Refour is born to take part in.

Replace: Wasting our trees has major consequences for our biodiversity and with this our climate. With RE-4 we offer corporations to change their path and replace all non-circular paper-based (multi-material) packaging. A path where no trees are harmed but protected, just like the food we package, thanks to RE-4’s combined protective properties of plastic yet foldable properties like paper.

Re-4 is produced as roll stock equal to paper rolls, developed as a drop-in solution to offer an easy replacement for our customers. It can run on current customer equipment with only a few minor alterations, this way likewise ensuring that the customer can uphold its current capacity.

Reduce: RE-4 is based on a unique mono-material composition, which is primarily a mix of air and minerals often at a rate of around 50% and 20% respectively, leaving only a reduced amount of PP used. It’s combined in a redefined foaming process, which offers several benefits, all contributing to a close to 40% reduced carbon footprint (flat-rate average) compared to conventional equals. Due to its mono-material yet multi-layered structure, we can mix in PP recyclate and thereby, reduce the need for virgin raw materials and the amount of waste ending up at incineration or landfill.

Our reduced use of raw materials and cheaper filler in form of minerals, allow us to offer RE-4 at a 40% lower cost price (flat rate average) compared to conventional equals. As follows, we can eliminate the trade-off many companies are often faced with of being either eco-conscious or cost-effective.

Reuse: RE-4 is strong enough for reuse and can go in the dishwasher again and again and again. Encouraging consumers to refill their bottles or reuse their cereal boxes as kitchen storage.

Recycle: RE-4 is a certified mono-material and can keep its mono structure even after being mixed with recyclate, guaranteeing 100% recyclability. RE-4 fits into current recycling infrastructures. Closing the loop with RE-4 will be an easy task; with its mono-structure yet hybrid function it can both follow the current PP stream and be detected as its own category with, among others, the NIR technology.

Mono-materials are often easier to label, collect, sort, and recycle, which streamline the recovery and recycling process and with this lower-end-of-life costs for the companies when the new Extended Producer Responsibility schemes become effective.

Altogether, RE-4 contributes to reducing CO2 emissions, waste pollution, extraction of virgin materials, deforestation, and the costs of making the sustainable choice. Creating a win-win situation for our planet and for our customers’ bottom lines.(2)

When going shopping, look for the RE-4 stamp. We have added a RE-4 stamp to all packaging made from the Refour material. This way, making it easy for you to choose purpose-driven brands and help our planet one product at a time.

By choosing products with the RE-4 stamp, you support our mission to help stop climate change. Every time you chose a RE-4 stamped product, you will have contributed to saving our trees, lowering CO2 emissions, and pushing for a circular economy.

Earth Overshoot Day, the day on which the planet’s annual resource budget is surpassed, is arriving sooner each year. In order to change the course of this progression, we need to act now and work towards a more sustainable future. One key transition is moving away from the take-make-waste linear model we are currently living by and moving to a circular economy.(3)

There are several positive outtakes from moving to a circular economy, but perhaps the two most important ones, are the benefits it will have for human health and our planet. According to the Ellen Macarthur Foundation a circular economy could, for Europe alone, cut our CO2 emissions in half by 2030, coming close to EU’s target of cutting emissions with 55 percent. In turn, this would contribute to saving the lives of 290,000, otherwise lost to air pollution every year.(4)
