Technology
Our cutting-edge patented technology extracts both 'long' and 'short' bamboo fibers, transforming bamboo into a sustainable bio-fiber for crafting lightweight materials in high-performance composites.
Why bamboo?
Bamboo fibers are both renewable and sustainable, thereby gaining significant interest as alternative to conventional fossil materials such as steel, aluminum, glass, and carbon fibers. It is easily available due to its abundance in the world when compared to other commonly used natural fibers in the market. Additionally, bamboo sequesters a high amount of CO2 during its growth phase, which is stored in the culms and the extensive root network.

Fire resistant
For our customers we develop products that requires their demands. In Automotive fire resistant or retarding is very important. Bambooder has developed a 100% biobased + fire resistant composite.
Moisture resistant
The reduced moisture absorption in bamboo can be attributed to the hydrophobic nature of lignin. Bamboo fibers contain approximately 30% of lignin. Characterized by aromatic rings and an amorphous structure, lignin is deposited in cell walls and intercellular spaces after the formation of cellulose and hemicelluloses, providing additional resistance to compressive forces. With its composition of aromatic rings and aliphatic chains, lignin enhances water resistance, making it more effective in repelling moisture when compared to cellulose and hemicellulose
How it works
Frequently asked questions
The raw material needed for the production of short fiber(s) (mats) comes from short bamboo chips. The bamboo chips are by-products obtained during the production of the input material needed for long fiber production and during long fiber production itself. Hence, no bamboo is wasted in our production process and we are able to fully utilize the bamboo culms.
The high growth rate and biomass yield of bamboo result in a large CO2 uptake. The CO2 that is taken up by the plant is stored in both the culms as well as the extensive root network. This attributes to a CO2 uptake during its growth phase up to 50t CO2/ha/y. The fiber production process of Bambooder only consumes electricity and no polluting chemicals are used. The electricity used is sourced 100% from European wind energy, resulting in a very low CO2 emission during the process. The process combined with the CO2 uptake result in a negative carbon footprint of our fibers after the extraction process.
Bambooder does not yet apply sizings to the fibers to enhance the interfacial adhesion of fiber and matrix. We are currently developing a novel biobased sizing together with the Luxembourg Institute of Science and Technology that will improve the interfacial adhesion of the fiber and matrix and improve the thermal stability of the fibers.
The fiber volume fraction of the long fiber yarns can be controlled according to the requirements of the customer. Standard, bambooder aims at is a fiber volume content of 95%. But bambooder can also produce prepreg yarns and generate a 50% fiber volume fraction.
Semi-finished products derived from the yarns (textiles/UD-tapes) can be processed into composites with commonly achieved fiber volume fractions just like any other glass or flax fiber textile or UD tape.
Short fiber mat thermoplastic prepregs are available with a fiber volume content between 30 and 70% depending on requirements for specific applications. For thermoset applications, the fiber volume content can be in the same range depending on the required performance for certain applications.
Bamboo is easily available due to its abundance in the world when compared to other commonly used natural fibers in the market. Over 30 milion hectares of bamboo are readily available. Bamboo has a growth phase lasting 6 to 7 months wherein the culms grow at a rate up to 1m/day. The growth phase is followed by a maturing phase wherein the culms gain strength. Generally, bamboo is harvest after 3 years with a yield of almost 40 t/ha/y. Additionally, bamboo sequesters a high amount of CO2 during its growth phase (up to 50t CO2/ha/y), which is stored in the culms and the extensive root network.
The fundamental fibers are tube-shaped cells with thickened walls, generally consisting of four layers around a central opening. Each layer is made up of semi-crystalline cellulose microfibers embedded in a hemicellulose/lignin matrix at a specific angle.
