Biobased materials



​A broad mastery of biomaterials and processes

More than 100 specialists at VTT are engaged in developing biobased material solutions. Our extensive research and development extends to natural and man-made fibres, nanocellulose, biopolymers, composite and foam technologies. We serve clients from the idea generation stage through laboratory and pilot stages all the way to market-ready applications. We also support customers with techno-economic viability studies and product safety controls.

Cut weight, cut cost, add value today

VTT serves its customers with lean, science-based R&D process and an economical way to develop new applications for biomaterials. In addition to lighter weight, we develop material applications delivering higher strength and added functionality.

VTT’s ability to demonstrate and pilot new bio-composite and high bulk fibre products—as well as our knowledge of and relationships within other industries—drives huge value for our customers.



Functional fibres

​Fibres with desired properties give efficiency to processing and add value to the end product. VTT can help you in tailoring your fibres to suit to your processes and increasing functionality to your fibre materials. 
Whether you want to increase fibre performance in your current process and products or to create completely new fibre based products, VTT expertise is on your service.

​ ​​​

​​​Tailored pulps for different end products

Besides understanding the importance of size, conformability and surface characteristics of particles with respect to end-product performance, we also can evaluate the processing options for achieving the required property combinations

​ ​​​

​ ​​​


Foam forming platform

Foam forming enables a step like change in the resource-efficiency for various product sectors including paper, paperboard, tissue, non-woven and even construction and insulation industries. We have extensive expertise in biopolymers, composites, foam structures, fibres. We are strong on process, with testing and pilot production facilities across the value chain—from raw materials to end products.

​​​​Fibre webs with novel features

VTT brings novel features to fibre webs by novel technologies and by introducing novel raw materials: increase in strength, good barrier properties, unique level of mouldability.


​​​Fibre upgrading

VTT has combined its expertise in chemical pulping, enzymatic and mechanical treatments: Fibres with high purity and proper polymer chain length can be produced from paper grade pulp, and even from recycled and waste material.

​ ​​​

​​​Acoustic elements

The new materials are developed by combining VTT’s knowledge of natural fibres, acoustic engineering and foam forming production technology. Foam forming enables the production of acoustic materials: wet fibre foam creates a porous structure with the open air pockets needed for sound absorption.

​ ​​​

​​​Fibre cushion for packaging

Strong competence on unit processes such as forming and drying are basic in developing new fibre-based products. One example is lightweight material for replacing EPS in the cushioning of different packaging needs.

​ ​​​

​​​Thermal insulation

VTT is developing technologies to use bio-polymers and wood fibre in thermal insulation materials: environmentally friendly, renewable raw-materials and cost-efficient production processes.
