Success Stories

EcoBuild has several success stories to share, find out more by scrolling down this page. 

Fire protected surfaces (Pre study)

Challenge:

Are there any sustainable alternatives to conventional fire retardants?

EcoBuild’s contribution:

A concept for fire retardants of surfaces with films consisting of nanoclay and nanocellulose developed at the KTH [1] has been tested through a direct application on wood. The purpose was to evaluate the application method.

Results

Fire tests show an extended time for ignition when wood surfaces has been surface treated in lab scale with clay and nanocellulose. A direct application is reasonable from an industrial perspective, however, more work needs to be done before the concept is ready to be up-scaled. Funding for continued research has recently been approved.

Performance of a new water-based fire retardant in wood based panels

Challenge
Current solution for fire proofing wood based panels are often solved using toxic or eco-unfriendly systems. Leaching of these systems may also impact the surrounding environment.

EcoBuild’s contribution
Spray-on treatment in pilot scale as well as producing the boards to be evaluated. Ecobuild also performed small scale fire tests as well as environmental assessment using life cycle analysis of the different formulations and putting them in perspective to existing benchmark products.

Results
The treatment formulation shows improved results both in terms of fire retardancy and mould resistance as well as positive outcome of the LCA compared to the benchmark products. Furthermore application by spray-on gave better distribution of the treatment compared to dipping fibres in solution.

An attractive boat deck

Challenge
Many boat builders have asked for environmentally uncontroversial alternatives to teak decks, with retained technical and aesthetic properties.

EcoBuild’s contribution
Within the EcoBuild frame, SP and two Norwegian companies have taken promising research results on furfurylated wood all the way to a successful industrial implementation.

Results
After the launch of Kebony Maple Boat Deck the demand on all their fufurylated wood products has increased dramatically, and the production is now covered by orders for a long time ahead.

High value furanic compounds from residue streams

Challenge
To demonstrate to Swedish industry the possibility to take bioprocessing of wood and agricultural residues from “concept” to “delivery” (demo scale).

EcoBuild’s contribution
Provide links to ongoing projects where furanic components can play a significant role (e.g. BioCoilCoat).

Results
Demonstrated extraction of chemical compounds (furans, sugars, acids) from biomass at demo-scale. Use of filtration and ultra-filtration in pilot scale to fractionate/separate compounds. Lab scale conversion to intermediate furan compounds.

A coil coating system with less environmental impact

Challenge
SSAB Tunnplåt who until now have used large volumes of paints made from petroleum feedstock wanted an alternative with less environmental impact.

EcoBuild’s contribution
EcoBuild has enabled a follow up on promising research findings at KTH on reactive biobased diluents all the way to industrial implementation.

Results
The results led to a full scale industrial implementation. For SSAB this means that a large share of their production now is coated with a paint that is much more environmentally benign, due to a decreased amount of solvents.

Increased content of biobased chemicals in coil coatings

Challenge
European sheet steel industry is annually using 180 000 tonnes of paint for their coated products. The challenge is to meet the market driven demand of increasing the content of ”green carbons” in the paints, whilst maintaining the properties.

EcoBuild’s contribution
Development of polyesters based on renewable furan chemical building blocks and put into perspective through sectorial development within the Furu2Furan-project and its subprojects.

Results
It has been shown in pilot scale that the content of “green carbons” can be significantly increased in coil coatings.

Development of wood fibre composites with IKEA

Challenge
WPC materials for furniture applications were already tried by IKEA. Improvements were needed regarding mechanical properties and visual appearance, which became the focus for the development work within EcoBuild.

EcoBuild’s contribution
The material was optimized for various injection moulded products by influencing and controlling the wood-plastic interactions. The injection moulding process was adapted to give the desired appearance of the surfaces.

Results
Wood fibre composites are now used by IKEA in some products and the use is expected to grow.

CelluNova – textile fibres from forest resources

Challenge
Current cotton production is not sustainable, neither environmentally nor socioeconomically. This calls for a development of new, environmentally sound high quality textile fibres from wood cellulose.

EcoBuild’s contribution
EcoBuild brought together key operators from several industrial sectors in the project ”CelluNova” for joint development of textile fibres from forest feedstock.

Results
New fibres with very good properties were spun. The project has led to several spin offs such as the H2020 project Neo Cel and the research programme Mistra Future Fashion.
