What does
?

Production service provider
Support in the use of natural fibres through customised solutions – from determining your needs to practical implementation in production.

Production of natural fibres.
High-quality natural fibres are produced from plant residues to replace synthetic materials in a sustainable way and to enable a wide range of applications.

Development of innovative technologies
Efficient processing of our renewable raw materials is implemented by avoiding unnecessary work steps, which significantly reduces environmental pollution in new products.
Global demand
meets sustainable material solutions.
time-saving
low-emission
cost-reducing
Agricultural residues are emerging as the resource of the future:
The cutting-edge GROW-Tech technology enables the production of natural fibers that are processed without the need for retting or drying and are 70% longer than conventional alternatives. This breakthrough offers a more efficient and sustainable solution for industries such as construction, automotive, and textiles, where high standards for quality, performance, and environmental sustainability are essential.
Global challenges demand climate-smart solutions.
High volume of residues
Each year, 140 billion tonnes of agricultural residues are generated globally, with the majority left unutilized, posing a significant strain on the environment and natural resources.
Limited fossil resources
The availability of fossil raw materials is declining, while their lifecycle continues to cause growing ecological harm. Developing alternative solutions is essential to maintain product quality and sustainability.
Untapped agricultrual residues potential
Agricultural residues have the potential to be valuable raw materials for new, sustainable products. Their thoughtful utilization is key to replacing fossil resources in the long term.
Severe environmental pollution
Burning or landfilling agricultural residues raises CO₂ emissions and accelerates climate change. Effective waste conversion solutions remain largely underexplored.
Growing demands
Stricter environmental regulations and growing consumer demand for ecological products are forcing companies to find new solutions that meet sustainable standards.
Lack of scalable alternatives
Existing approaches, such as burning agricultural residues to generate energy, are inefficient, produce emissions and offer little economic added value.
Intelligent solutions for global industrial challenges:
Innovative processing technology for natural fibres from agricultural residues
GROW-Tech technology reduces processing steps from 10+ to just 4.
It processes agricultural residues such as leaves and stems into high-quality natural fibers.
No need for chemicals for retting or bleaching.
A scalable automated process saves time, costs and resources.
Environmentally friendly solution: minimises water consumption and CO2 emissions.

Substitute for mineral wool
NatStruct develops sustainable material alternatives for Teckentrup, a leading door and gate manufacturer. As part of a three-year project, the team has developed and established a proprietary testing procedure. Initial results show that regional material solutions are not only possible, but can also be successfully implemented with strong partners. The project is funded by the ‘research allowance’.


Sustainable PU foam
In collaboration with the University of Applied Sciences in Kaiserslautern and the EU project ‘BIOMAT-Testbed’, NatStruct is working on a more sustainable alternative to PU foam for doors and gates. Integrating this into existing products is a particular challenge that the team is actively addressing. The project is also financed by the ‘research allowance’.


EU ‘Save the Planet’ call
NatStruct is participating in the EU’s ‘Save the Planet’ initiative together with L’Oréal, P&G and the University of Applied Sciences in Kaiserslautern. The focus is on using the prototype for innovative fibre separation and testing procedures to pave the way for future-oriented, sustainable solutions.


Long-fiber production: Pioneering research for the future
NatStruct is working with the renowned Jülich Research Centre and Professor Ulrich Schurr to further develop fibre separation processes. The prototype is used for tests with native and exotic plant species such as date palms to set new standards in materials science.
Target ARR: €24 million within the next 5 years
