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. www.stendenpre.com

BIOMIMICRY FOR BUILDING MATERIALS BIOPREG a thermoplastic biocomposite reinforced with natural fabric Fully biodegradable anf 100% recyclble As stiff as glasfibre composite but two times greener 5 times stronger then soft wood C18 The first high performance biocomposites for structural applications Suitable for outdoor applications Resistant to water, chemicals and sunlight (UV) Can be cutted, sawed drilled and painted, printed and glued
Color samples
DESIGN PROPERTIES Textiles can be painted and printed. Textures, sheets and foam can be pressed within one step. Thin sheets can be folded and cutted
Two processes for BIOPREG: filmstacking and mixed textiles
PROPERTIES Different polymers are possible: PP PLA, PET, PA Properties are comparable to High pressure laminate (TRESPA) Very robust and impact resistant.

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.
