The adoption of the Packaging and Packaging Waste Regulation (PPWR), retailers and brand owners are under increasing pressure to reduce their environmental footprint.
The regulation sets ambitious targets for packaging waste reduction, recyclability and responsible use of resources. Paper carrier bags meet the highest standards. They are made from renewable raw materials sourced from sustainable forest management and are reusable and recyclable.
But that’s not all: the kraft paper and paper carrier bag manufacturers are constantly working to conserve resources, minimise environmental impact and increase product quality at all stages of the production process – and they have been doing so long before the PPWR came into force.
“Saving resources has a long tradition in our industry,” says Elin Gordon, Secretary General of CEPI Eurokraft. “The concept of sustainability was introduced in the early 18th century in connection with the responsible use of wood as a resource. And this principle still defines how we operate today.”
The primary raw material for kraft paper is wood fibre, mostly sourced from sustainably managed European forests. In these forests, trees are selectively harvested, primarily removing dead, weak or misshapen ones to support healthy growth. This practice supports the objectives of the EU Deforestation Regulation (EUDR).
FSC® and PEFC™ certifications also ensure the traceability of the raw materials and confirm that they originate from responsibly managed, deforestation-free sources. Adding to that, the kraft paper industry relies on process waste from the timber industry such as wood chips and thinning wood – this way, no part of the tree is wasted.
”This no-waste principle is continued throughout the production of kraft paper and paper carrier bags,” explains Gordon. “Wherever possible, materials are utilised and recycled.” One example is that internally generated biofuels, such as black liquor, are used in the mills’ energy mix.
Kraft paper production is highly energy-efficient. A large proportion of renewable energy sources is being used, while the reliance on fossil fuels is decreasing. According to a study by RISE, in 2021, biofuels accounted for 92% of all fuels consumed for kraft paper production, with 78% being generated in the mills during the production process.
Additionally, the mills produced 59% of their own electricity requirements. Of the purchased grid electricity consumed by the mills in 2021, 29% was identified as “green” electricity. In addition to energy, water is used efficiently and responsibly in the papermaking process. Most pulp and paper mills are strategically located near abundant water sources.
In Europe, the majority draw primarily from surface water – rivers and lakes account for 87% of their intake. Groundwater provides another 12%, while only 1% comes from public water supplies. Since the 1990s, the industry has reduced the average water intake per tonne of paper by approximately 40%. Modern paper mills treat and reuse process water multiple times before returning around 90% to its source in a clean state. The remaining 10% either evaporates, remains in the product or is retained in solid waste.
