11. New Trends and Regulations in Europe
• city of Amsterdam declared mandates for new housing to
use biobased materials, beginning in 2025
• 20% of new housing projects must be constructed with
wood or other bio-based materials
• a detached house has to be 80% bio-based, and buildings up
to ten stories can be just 65% bio-based material. Housing
over ten stories must be at least half bio-based content.

15. Circular Operational Concepts
Value chain collaboration, co-creation, partnerships,
platforms, practical business models or operational
concepts that improve circularity at organisational level

16. Efficiency and processing
High process and material efficiency, cost-competitiveness,
optimised use of wooden raw materials by machinery and
treatment methods

17. ➢ For the surface treatment no chemicals are needed so that the overall purity of the
product is improved and remains
➢ Public acceptance and awareness for alternative treatment methods of wood can be
achieved by façades and other visible applications
➢ Culturally distinctive techniques can be re-vitalised as novel circular approaches
Old technologies can support
circular innovation
• Carbonisation by charring under defined
conditions can alter properties and can
achieve wonderful wooden designs
Why is it a good practice?
➢ Cascading usability of the material is
enforced: fully recyclable and reusable

18. Why is it a good practice?
➢ use of 100% untreated recycled wood is technically possible and
provides a high added value to recovered wood because products are
completely recyclable and can be disposed and collected at recovery
centers.
➢ Some producers of insulation fibre boards collect used panels to be
processed and reused in the same application.
➢ Wood-fibre boards known for low volatile organic compound emission
ratings and for improving indoor air quality
Reuse of low-density fibre-
boards for insulation use
• Engineered wood products produced by
interacing of wood fibers with small amount
of binders

19. Why is it a good practice?
➢ Bath modules are highly efficient. Building materials in bigger sized formats can be
used, which would not be possible at a common construction site.
➢ Bath modules enable to add storeys to the roof in metropolitan areas, as they only
have to be lifted in and connected on site. This makes reuse of buildings more feasible.
➢ Bath modules provide better social acceptance for building projects as they shorten
the construction site time and thereby relieves traffic and residents.
Ready to install modules for
wood construction
• Construction of individual bathroom modules
combining power distribution, ventilation and sanitary
facilities
• Some companies produce modules in pop-up
factories on site

20. Reuse and Recycling
Reuse and Recycling concepts and design approaches in
line with the Circular Economy concept

21. ➢ Modular design approach and embedded smart sensors can prevent decay and
prolong the product life span
➢ Digitalisation concepts and tools like apps for wood sharing are innovative approaches
that improve consumer perception and behaviour
A new life for old windows and
doors
• Recovery of wooden windows and doors made
possible by new circular design approaches
Why is it a good practice?
➢ Real upcycling of wood enhances and enhancing
the product lifetime
Source: MSORA

22. Why is it a good practice?
➢ Recovery of resources in buy-back systems can be well-controlled, which also provides
options enhancing the quality of the product
➢ Buy-back can still be named innovative and a new circular approach. Test loops will
need to confirm feasibility of the method in the near future.
➢ Buy-back can be a financially viable option while the quality of the back-received
furniture can be better controlled.
Reuse, recycling and
refurbishment of furniture
• Buy-back schemes for furniture as solution for
viable collection and retrieval
• Companies buy-back the products for % of the
sales price
Source: Green Furniture Concept

23. Why is it a good practice?
➢ Local recycling volumes of wood are increased on local level
➢ Furniture applications provide a good lifetime span so that the resource efficiency
can be highly improved
➢ Increasing the public acceptance of post-consumer fibers within furniture is very
important because these products are well-known and identified as high value
wood-based consumer goods
Upcycling in furniture value chains
• More and more designers establish start-ups
that produce furniture from locally recovered
wood
• Collection system needs to be in place

24. Waste and Side stream Utilisation
Added value to waste and side streams and new value chain
opportunities.

25. Why is it a good practice?
➢ Utilisation of high percentages of side-stream material from woodworking
industry enables a further stage of re-use and cascading and as a result small
parts from the tree can be used in the pencil industry.
➢ The use of energy and emissions from the production process is minimised
through optimised processing that reduces the number of usual multi-production
steps.
Pencils made resource-
efficiently
• Company produces pencils and crayons from three
granulates achieved by binding and recycling spruce
fibres with polymer matrix
• Special developed co-extrusion process joints all pencil
materials

26. Why is it a good practice?
➢ The use of pine wood waste and side streams in added value, innovative
and profitable products
➢ Replacement of fossil material (plastic) with renewable material in the
composite products
➢ Reduction of greenhouse emissions
Antibacterial composite material
from wood side streams
• Fibres from pine wood possess antibacterial compounds, that
provides added value to the fibre-reinforced biocomposites
• Antibacterial property of the pine fibres are exploited in
biocomposites designed for toys and materials for construction
interiors.

27. Why is it a good practice?
➢ Recycled material use provides high circularity advancement with improved raw
material use and availability of side streams for production of components such as
wooden insulation panels
➢ Sustainable solution with reduced emissions and a long lifetime of wood-based
buildings due to better recycling options
➢ Improves consumer awareness of more sustainable prefabricated housing options
Circularity in manufacturing
pre-fabricated houses
• Insulation material generated from sawdust in
production process presents profitable product with
resource and energy savings

28. • Access to diverse forest resources is a core strength
• Wood-working industries gain a more central role in
regional economy
• Transition towards circularity supported by
incentives from public bodies
• CE concept is realised in reuse and recycling and
resource efficiency by good actor collaboration,
adaptation and standardization of processes and
new business models
Strong potential for green industrial growth and business model innovations with a wide
diversity of forest resources
Central-Eastern macro-region

29. • Large portfolio of high value-added products due to
recycling and waste management
• Support by effective policies
• Consumer awareness is addressed by new
responsibility schemes
High value-added production integrating effective reuse and recycling steers innovation
Central-Western macro-region
