Blue Ocean Closures changes the world with wood fiber-based screw caps

Imagining the sheer number of plastic caps used globally each year is a daunting task. From bottles and milk cartons to beauty products, hygiene items, and pharmaceutical containers, an estimated 2.2 trillion plastic caps are produced annually. This staggering number highlights both the environmental challenge and the immense potential for Blue Ocean Closures’ innovative wood fiber-based screw caps, developed in Säffle, Sweden.

“We are already collaborating with major global companies excited about our product,” says Lars Sandberg, CEO and Founder.

“Well-known brands like Coca-Cola, Absolut Vodka, and L’Oréal have set ambitious internal targets for reducing plastic use and improving recyclability to lower carbon emissions.”

Lars Sandberg’s career has been shaped by his passion for forestry and the potential applications of wood-based resources. Originally from northern Sweden, he eventually settled in Värmland, attracted by opportunities to work with leading companies in the forestry, pulp, and paper industries, including Stora Enso, Tetra Pak, and Billerud.

"Our goal is to replace as much plastic as possible"

“In recent years, I’ve become increasingly focused on reducing reliance on plastics and fossil-based materials by developing bio-based alternatives. I find it incredibly rewarding to be involved in the entire process—from a concept to a fully realized product.”

In 2021, Sandberg launched Blue Ocean Closures after acquiring the rights to a promising technology for producing durable, recyclable fiber-based products.

The technique involves pressing wood fibres together in a dry process. It is the high density of the fiber material that gives it its unique properties.

“There are others using similar techniques for hangers and trays, but we are currently the only ones able to manufacture highly sophisticated shapes. Our screw caps, made from the same fibers as paper, can be recycled in the same way. Our goal is to replace as much plastic as possible, and it’s encouraging to see other companies working toward the same mission.”

Operations in Säffle, Värmland

Leading industrial groups, including Alpla Group, Rottneros, and Glatfelter, have invested in Blue Ocean Closures, recognizing the technology’s potential early on.

In 2024, the company scaled up production and launched its first products on the market.

“The feedback has been overwhelmingly positive. We’ve been told that our screw caps match or even surpass the functionality of their plastic counterparts, especially in terms of torque performance. For the global brands we collaborate with, functionality is non-negotiable.”

The decision to establish operations in Säffle was deliberate. While most of the company’s 25 employees are based in Karlstad, a 45-minute drive east, Säffle offers a rich industrial heritage in fiber-based manufacturing. Proximity to Karlstad University, with its focus on green transition and bioeconomy research, and membership in clusters like Paper Province and IUC Steel & Engineering, provide valuable networks and foster collaborations.

“Säffle’s long-standing tradition in fiber product manufacturing and the investment support we received through Region Värmland were decisive factors. The local talent pool, especially skilled operators and engineers with backgrounds in the pulp and paper industry, has been a tremendous asset.”

Collaborative environment

Sandberg acknowledges the advantages of launching a startup with extensive industry experience, even as he navigates the new challenges of entrepreneurship.

“Statistically, entrepreneurs with significant industry expertise often drive groundbreaking innovations. This applies not only to our work but also to other successful companies in Värmland, such as Woodtube in Säffle and Biosorbe in Sunne.”

“It´s important that we collaborate to sustain the region’s unique innovation climate. Startups play a critical role in creating jobs, fostering new skills, and generating knowledge. It’s vital that we work together to maintain Värmland’s reputation as a hub for innovation.”
