Cellulose fibres are emerging as a sustainable option for wrapping everything from foods to electronics.<\/p>\n

By<\/em><\/strong> \u00a0Helen Massy-Beresford<\/p>\n

Attention supermarket shoppers in Belgium, France and Luxembourg: a test to cut waste from plastic packaging of foods is coming to nearby stores.<\/p>\n

Retailers Carrefour and U-Group plan to sell yoghurts, cheeses, fruit juices, biscuits and other items in packaging made of cellulose fibres, which come from wood or other plant-based materials.<\/p>\n

Market moves<\/strong><\/p>\n

In total, 30 to 60 stores in the three countries will start featuring the environmentally friendly wrappings on 13 types of food by the end of this year.<\/p>\n

Carrefour and U have teamed up with food producers, packagers and researchers in a project that received EU funding to help get green packaging materials into stores.<\/p>\n

\u2018Without market uptake, bringing sustainable products to shelves is no more than wishful thinking,\u2019 said Frank Gana, chief executive officer and co-founder of a Paris-based environmental consultancy named (RE)SET.<\/p>\n

It leads the EU project, which is called\u00a0R3PACK<\/a> and runs for three years through May 2025.<\/p>\n

The goal is for the industry players in the initiative to replace a significant portion of their plastic packaging with fibre-based versions. Food producers such as Candia and packagers including Thiolat \u2013 both also based in France like Carrefour and U \u2013 are committed to the goal and leading the effort.<\/p>\n

The test that will start later this year in Belgium, France and Luxembourg is due to be extended to thousands of stores in the three countries by the time the project wraps up.<\/p>\n

Packaging piles<\/strong><\/p>\n

Europe\u2019s pile of packaging waste comes from far more than food items. From takeaway coffee cups to boxed-up electronics, Europe generates nearly 190 kilogrammes of packaging per person each year \u2013 or 84 million tonnes in total in 2021.<\/p>\n

Plastic packaging is a particular threat because, although some is recycled, much ends up in the ground, rivers and seas. In 2021,\u00a0almost a fifth<\/a> of the EU\u2019s packaging waste was plastic.<\/p>\n

In addition to replacing plastic packaging, the R3PACK team is seeking to make some wrapping reusable.<\/p>\n

\u2018For some products it will be nearly impossible to replace plastic,\u2019 said Gana. \u2018In some cases, it\u2019s easier to make reusable packaging.<\/p>\n

While consumers, authorities and businesses alike want to reduce single-use plastic packaging, finding a suitable replacement is a big challenge precisely because of the material\u2019s qualities: it is light, cheap to produce and can protect the contents inside from oxygen, moisture and water.<\/p>\n

One solution is to cover cellulose- or paper-based packaging with lamination or coating \u2013 or a combination of both \u2013 to bridge the gap with plastic\u2019s useful qualities.<\/p>\n

Swedish breakthrough<\/strong><\/p>\n

Anna Altner can attest to the challenges \u2013 and breakthroughs \u2013 in the field of sustainable packaging.<\/p>\n

She is the founder of a Swedish startup called Yangi, which\u00a0developed cellulose-based packaging that can compete with plastic economically.<\/p>\n

That\u2019s because the company\u2019s manufacturing process is less\u00a0energy- and water-intensive than those of other makers of cellulose-based packaging and because the final product, like plastic, is versatile.<\/p>\n

The process is called \u201cdry forming\u201d and relies on air instead of water to separate the fibres, which come from sustainably managed forests in Scandinavia.<\/p>\n

\u2018We are much more price competitive, compared to plastics, than existing solutions,\u2019 said Altner. \u2018Plastic is so cheap, there is no paper solution that can compete with it.\u2019<\/p>\n

The company\u2019s processing breakthrough came in another EU-funded research project that she led. The\u00a0project<\/a> ran from April 2021 until the end of 2023.<\/p>\n

Under the new processing method, pulp is fed through a mill to separate the fibres. Air is then introduced to separate them further into single fibres.<\/p>\n

With a continuous air-circulating system, the fibres are then formed into fluffy pads that are laid on a formation line. Heat and pressure are applied, creating a rigid 3D packaging made of cellulose.<\/p>\n

The method not only saves water but also consumes less energy than current manufacturing methods for cellulose packaging \u2013 no small consideration for manufacturers amid high energy prices.<\/p>\n

The new packaging could be used for everything from takeaway salad bowls to blister packs for electronics. What\u2019s more, it can be recycled in existing paper-recycling arrangements.<\/p>\n

Greener frontiers<\/strong><\/p>\n

In December 2023, EU governments\u00a0agreed<\/a> to amend European legislation on packaging waste to increase the reuse of packaging and make all of it recyclable.<\/p>\n

That ties in with the European Green Deal and EU drive towards a more\u00a0circular economic model<\/a> in which resources find their way back into the economy for reuse instead of being discarded.<\/p>\n

\u2018We\u2019re seeing the same trend towards tightening regulations on packaging globally, even if Europe is ahead,\u2019 Altner said.<\/p>\n

For his part, Gana of (RE)SET said that tackling plastic packaging could help pave the way for deeper across-the-board cooperation in Europe to green the economy.<\/p>\n

\u2018If you want to run a marathon, you need to start with a 10K,\u2019 he said. \u2018Packaging is a good first step.\u2019<\/p>\n
