Sulapac Ltd.


Sulapac® is a fully biodegradable and microplastic-free material, primarily made of wood and plantbased binders. Plastic product manufacturers can use Sulapac® with their existing machinery, making sustainability an easy choice.

The company was founded in 2016 in Helsinki, Finland by two biochemists, Dr. Suvi Haimi and Dr. Laura Tirkkonen-Rajasalo, who set out to find a solution for the world’s plastic waste crisis. Utilizing their expertise in biomaterials Suvi and Laura came up with a sustainable and beautiful alternative to plastic. Sulapac’s first patent was approved in 2016 and today the portfolio consists of several material alternatives and a ready-made collection of products. Sulapac® is suitable for variety for applications   rom cosmetics packaging and personal care items to clothing hangers, straws and more. The greatness of the innovation lies in the combination of a unique material and production technology readily available: Sulapac can be used as raw material on existing injection molding or extrusion lines.

A Holistic Approach to Sustainability

Sulapac is safe and circular by design meaning the company has taken a holistic approach to sustainability by carefully considering the entire value chain and life cycle of a product. Sulapac’s raw materials are safe for people and the environment: Sulapac is 100% microplastic-free and biodegrades fully into CO2, H2O and biomass in a similar time frame as a piece of natural wood of same size. The raw materials are sustainably sourced and the wood ingredient in the compound comes mainly from industry side streams. In the recipe development the goal is to maximize the plant-based content in order to reach carbon neutrality.

The Sulapac Premium and Universal materials for injection molding are 100% plant-based.
Sulapac is recyclable via industrial composting, which is a way to close the organic cycle. Mechanical recycling is also a feasible option, as soon as the volumes of Sulapac waste increase. Preliminary tests have shown that Sulapac can be recycled up to 6 times. Chemical recycling via pyrolysis is currently under investigation.

Sulapac believes that replacing plastic is just one part of the solution to the plastic waste problem and encourages everyone to commit to each of the 4 Rs: to reduce, reuse, recycle, and replace plastic. “We want to challenge all organizations and individuals to approach sustainability in a holistic way. The prevention of microplastic pollution is one aspect and we are happy to share our expertise on this topic.” – Maija Pohjakallio, Sustainability Director, Sulapac
