Research
Recycling / Upcycling
Upcycling is the reuse of plastics for higher use applications. This can be done by
removing plastic parts from discarded products, or by processing plastic waste into a
valuable raw material.
Biopolymers
The term biopolymers has two meanings and in practice they often go together.
Polymers of biological origin are often called biopolymers, however polymers that
are biodegradable are also called biopolymers.
Smart Materials
In this topics research and development is performed for smart or sensory
materials. For instance the use of sensor technology in textile applications.
Examples include protective clothings and seatbealts.
Biocomposites
Materials that are made out of natural fibres like hemp, flax, wood etc. and
(bio)polymers.

SUITABLE CORE MATERIALS
1) Fibre insulations mats:
• Sheep wool
• Celluose-insulation
• Flax or hemp mat

2) Foam plates
• Recycled PET foam
commercially available. Not suited for
insulation but for high performance
construction panels and windmill bladed
• Paper foam

• BIO FOAM
Commercially available. Is a foam produced
from PLA granules that can be produced in
different densities. As a blowing agent, CO2
is used. It is Cradle to Cradle certified.
• PLA honeycomb
Commercially available. Is a foam produced
from PLA granules that can be produced in
different densities. As a blowing agent, CO2
is used. It is Cradle to Cradle certified.

3) Other core plates
• End grain Balsa wood
Balsa has a superior compression strength.
Local forming of the sandwich should take
place by milling the balsa core and
subsequently hot pressing of the facing.
• Paper honeycomb
Paper honeycombs are very common in the
furniture industry, like they are applied in the
doors cabinets and closets.
These honeycombs are cheap and come in
many varieties to fit the requirements.
Forming of the sandwich should take place
by milling or cutting out the honeycomb
locally and subsequently the hot pressing of
the facing.

Suitable top foils to improve weather resistancy and fire resistancy
• Geopolymer as binder for woodfibre or for natural fibres
• BIO PA11
