Division of Building Materials - EnWoBio
Development of biobased concepts for the construction sector
Hybrid and composite approaches to materials, products &construction
EnWoBio – Engineered Wood and Biobased Materials Laboratory:
New bio-composites: building materials refined from renewable resources based on wood or natural fibres and biopolymers or recyclable thermoplastics
New natural wood modification: new concepts based on combined mechanical-hydro-thermal procedure to obtain e.g. higher surface hardness, abrasion resistance, dimensional stability as well as increased decay resistance.
Physico-chemical and moisture analysis of bio-based building materials:Moisture sorption; fungal decay resistance, dimensional stability, mechanical performance and insulating capacity of bio-based materials
Engineered wood products for the construction market: Development of new bio-based products to enhance energy and cost efficient building processes. Engineered wood products (EWP) to support the needed societal development.
LCA and ecological-socio-economical aspects of biobased building materials: A proactive activity to draw a strategic roadmap for sustainable innovations for biobased building materials.

3Andreas Falk, ERA-Can workshop June 7-8. 2016 Bath
Interest in material combinations and hybrid approaches
Material properties and material choices
are of increasing importance today, having effect on energy production,
maintenance needs and life span of structures
Growth and urban densification
requires efficient construction processes
Building construction
is undeniably responsible for a big share of the emissions from society

4Andreas Falk, ERA-Can workshop June 7-8. 2016 Bath
Interest in material combinations and hybrid approaches
Horizon 2020
Increasing environmental concern i society
Material industrial interest
Drop on the pulp- and paper market calls for consideration of new markets
Timber industry mainly produces low-refined products (not much EWPs)
Swedish construction market
Suffering from ever increasing building costs, asking for increased efficiency

5Andreas Falk, ERA-Can workshop June 7-8. 2016 Bath
Interest in material combinations and hybrid approaches
New products with newly developed, innovative functions and/or
combinations
Reduced consumption of energy and material resources
More out of the utilised products and components in terms of rationality,
time- and economy-related efficiency and high performing supply of functions
Combinations of existing material properties to get more and improved
functions out of the products we manufacture.

6Andreas Falk, ERA-Can workshop June 7-8. 2016 Bath
Bio-based materials
are in focus to increase the use of not only timber but also wood in different form
and other bio-based material sources of local and regional importance
Hybrid concepts
are studied as an approach to decrease the environmental footprint
of built structures and to increase the adaptability of structural systems
Building technology development
makes almost anything possible, but what is reasonable?

Considering hybrid
• Hybrid as concept: a matter of synergy
• Targeting: Environment Society Economy
• Materials in use versus utilisation of materials

To conclude:
Elements and systems with multiple functions
• to create more with less, synergies
Functions as driving factors when choosing and refining materials
• Fire, Sound, Load bearing, Architectural functions, etc...
Level of refinement
• Considering production costs, embodied energy and waste
