It is about 20 cm long, looks and feels like raw pasta, and Suvi Haimi is hoping it could help save the oceans. The founder of Sulapac, a Finnish biocomposites startup, on Tuesday at the Slush startup conference unveiled an eco-friendly, fully biodegradable straw, which it hopes to market globally in partnership with Stora Enso, the Finnish pulp and paper company.
As lawmakers call time on plastics – thanks in no small part to the wave of public outrage unleashed by David Attenborough’s Blue Planet, and the European Parliament’s vote to ban certain single use plastic items in October – the market for bio-based alternatives is growing. “We had already seen a lot of interest in plastic alternatives, but this accelerated after the vote,” says Seppo Parvi, chief financial officer of Stora Enso.
For Stora Enso, working with startups like Sulapac is a form of future-proofing. Biocomposites and other new ventures account for around 7% of Stora Enso’s annual sales, or around €700m. Parvi is expecting this to double to 15% within the next few years. And so, in May it started working with Sulapac to create biodegradable caps and closers for drinks, before expanding to straws – which they plan to bring the market in the second quarter of 2019.
“We had a vision to save the oceans and the straw was one of the most visible plastic pollutants so we decided to focus on that.”

Sulapac is one of a number of startups racing to grab market share. Founded in 2016 by Suvi Haimi and Laura Kyllonen, Sulapac makes a number of packaging and other items from biocomposite – a combination of wood pulp and natural binders. These are designed to break down within 29 days in an industrial composter, around the same rate as a piece of wood, and will also biodegrade if they wind up in the sea.
Other European startups are exploring different materials.
In London Skipping Rock Labs, founded four years ago, has created an edible plastic packaging based on seaweed. The company, founded by Pierre-Yves Paslier and Rodrigo Garica Gonzalez, began with edible ‘capsules’ of water and this summer launched a line of ketchup sachets which it is trialing with 10 London takeaway restaurants and JustEat, the food delivery service, ahead of a a commercial launch next year.
There’s a snag, though: shelf-life. After just a few days the Skipping Rock Labs product – known as Ooho – will start to shrivel. It can tear easily and cannot be resealed, which makes it less attractive to potential clients like hotels, where there’s a big market for small toiletries. limited to instantly consumed products, such as drinks at festivals or fast food sachets.
Startups are finding that it’s often easiest to conform to existing systems and use cases. One of Sulapac’s advantages is that its material can be used in the same machines currently used to extrude conventional plastics, so that no extra capital investment is needed by companies if they switch, and a similar range of containers can be produced.
There’s also the challenge of cost.
Biodegradable alternatives to plastics are still much more expensive. A Sulapac straw costs more than three times as much as a plastic one, around the same as a paper straw. Haimi says that in time, with greater production volumes, biocomposites could become cost competitive with plastics, but that will not happen soon. For now though, much of Sulapac’s work is with luxury brands such as Chanel, whose customers can more easily absorb the high packaging costs.
Israeli startup Tipa, meanwhile, is tackling the issue of flexible packaging, such as the wrappers around coffee, fresh produce and snack bars. While rigid plastic containers are often at least partly recyclable, flexible packaging, which is not made of pure plastic polymers but a blend of materials, is much more difficult to reuse.
Founded in 2010 by Daphna Nissenbaum and Tal Neuman, Tipa had created a bio-based film that will compost fully in six months in an industrial composter. The material has been used by companies such as Ekoplaza, the Dutch supermarket, which made headlines in February for creating a completely plastic-free aisle in its stores.
There are still many questions about bioplastics, with some environmentalists concerned that while materials may degrade in an industrial composter, not all of them will break down in environments such as the ocean and could still be harmful to wildlife. Others question the eco-credentials of these materials given the amount of energy used to manufacture them, and their potential to divert farmland away from the production of food.
Nevertheless, with plastic bans likely to come into force across Europe within the next three years, companies and investors are sensing an opportunity. Tipa raised a $11m series-B funding round at the end of 2017, from investors including GreenSoil Investments, the Israeli agrifood tech venture capital company, and Horizons Ventures, Hong Kong billionaire Li Ka-Shing’s VC fund. Sulapac received €1m in seed funding from Lifeline Ventures, Arden Venture and Tekes and a €2m grant from the EU’s Horizon 2020 fund. It is planning to raise a series-A funding round in 2019.

Insider view: Minsk as a startup hub
Ruled since 1994 by autocratic president Alexander Lukashenko, Belarus has a curious mix of Soviet-era feel and tech entrepreneurialism. The tax-free Hi Tech Park, founded in 2005, has helped Minsk make a name for itself in games and AI. Yury Melnichek gives us the lowdown.
