Current projects

 

Junior research group

Young scientists from the Fraunhofer WKI and the TU Braunschweig are working together to develop solutions for sustainable buildings.

 

Crash-barrier system made from wood

Crash barriers provide a crucial contribution towards safety in road traffic. In Germany, these are predominantly comprised of steel or reinforced concrete. In collaboration with project partners, we are developing a sustainable alternative: a crash-barrier system made from indigenous wood species. It needs to be compatible with existing systems, just as durable and financially competitive.

 

Green Water

The Fleete (canals) of Hamburg's inner city were once full of life. Today, they are mainly unused and lacking in vegetation. The designers Beate Kapfenberger and Martha Starke would like to breathe new life into the urban waterways. With the support of the Fraunhofer WKI, they are developing floating islands which can carry plants and which are made from a robust and lightweight bio-material.

 

Sustainable building products from industrial waste

The global construction industry devours enormous quantities of fresh raw materials, in particular in the production of concrete. How can resource efficiency be improved? In collaboration with our project partners in Germany and China, we are developing sustainable concrete building materials and high-performance construction elements on the basis of construction/demolition waste and plant-based production residues. 

 

Lightweight sandwich element with recycled balsa wood

Using a stand-up paddleboard as an example, we are developing a lightweight-construction sandwich element using renewable raw materials. For the core, we are using balsa wood from disused wind-energy rotor blades, thereby offering a solution for their high-quality reutilization (cascade utilization). The outer shell will be made of natural fiber-reinforced bioplastics.

 

Ecological insulating materials and components for Chile

In this project, we will develop insulating materials from Chilean plants and largely unused plant “waste“ that accumulates in Chilean agriculture, forestry and timber industry. In this way, we contribute to sustainable forest management and to improving the environmental balance of the construction industry in Chile and open up new value creation opportunities.

 

Bio lightweight building board for the interior construction of ships

Due to the fire-protection requirements, solely non-regenerative materials such as aluminum or foam glass have been used up until now for interior fittings in ships. In this project, we are developing a non-combustible lightweight board made from plywood which is suitable for cabin construction in ships and which is, furthermore, much easier to work with.

 

Glimmer-protected wood-fiber insulation

Wood fibre insulating materials are good for the environment, but currently only reach building material class B1 (normally flammable). In building classes 4 and 5, they may therefore only be used with an approval in individual cases. We are developing a climate protection system for sustainable wood fibre insulating materials to improve their building material class and expand their market potential.

 

Long-term behavior of wood hybrid systems for sustainable buildings

In the establishment of sustainable construction methods for the future, wood plays an important role as a building material made from renewable raw materials. The native properties of wood can at present restrict the utilization of this sustainable material in construction projects. In order to compensate these typical wood properties, innovative hybrid systems can be advantageously applied.

 

Fire-safety in public facilities

What fire-safety requirements exist for products such as textiles, furniture and mattresses in public facilities? How can the requirements be fulfilled in the most environmentally friendly and health-compatible way possible? In this research project, we are developing a concise guideline with defined recommendations for purchasers.
