High-consistency enzymatic fibrillation (HefCel) is a cost-efficient way to produce cellulose nanofibrils – Join the consortium for up-scaling the technology



Cellulose nanofibrils (CNF) are promising bio-based materials for numerous applications, either as a replacement of oil-based materials in existing products, potentially with added functionality, or in generating completely new type of materials and products. VTT is looking for partners for up-scaling of the HefCel technology.

VTT turns discarded textiles into cellulosic man-made fibers 



70,000 tonnes of textiles is thrown away in Finland each year, and most of it is currently burned to energy. Around one third of the discarded textiles are made of cotton. Hence there is a huge and underutilized source of cellulosic raw material in Finland only. VTT coordinates a project called The Relooping Fashion Initiative that aims at modelling and demonstrating how closed-loop recycling of discarded textiles into new material can be done. The partners of the project; Ethica, Suez, Helsinki Metropolitan Area Reuse Centre, Seppälä, Pure Waste Textiles and Original Repack, represent the whole closed-loop value chain, and participate in a unique pilot production experiment in Valkeakoski, Finland.

BIORUUKKI pilot centre – a unique innovation and demonstration platform for bio- and circular economy technologies 



Bioruukki pilot centre is one of VTT´s most significant investments this decade. Bioruukki offers extensive possibilities for demonstrating how bio-based or recycled raw materials can be converted into various products, such as fuels, chemicals or materials. With the gradually expanding Bioruukki centre, VTT continues to invest in its ability to help companies to accelerate the commercialisation of their new bio- and circular economy innovations.

There is room for making paper stronger by improving bonding between fibres



The strength of paper is largely controlled by the bonds between individual fibres in paper. The stronger the bonds are the stronger is the paper. Strong bonding is a key for reducing the basis weight of paper products, saving fibre raw material and reducing the energy consumption in paper and board production. Results have shown that the bonded area can actually be surprisingly low and the bonds very weak.

New concepts for recycling of construction and demolition wood waste



Construction and demolition (C&D) wastes arise from renovation, construction, and demolition of buildings, roads, and bridges. Recycling of these materials is an essential component of sustainable building by reducing environmental impact of materials production, saving landfill space, reducing degree of incineration, and offering a raw material base for new materials. Together with three SME partners, VTT develops and demonstrates novel cost-effective solutions for a higher recovery of C&D wood waste.
