Material & wood chemistry


What does wood have to do with chemistry – well: simply everything! Wood is a heterogeneous mixture of biopolymers (cellulose, hemicellulose, lignin) as well as organic and inorganic extractives. In the application of wood, chemicals are used that wet, soak, digest or modify it. Environmental influences and use lead to degradation or contamination, emissions and leaching, and even if you leave wood alone, it exudes its scent. This raises many questions about the interaction of wood with the environment. We help to pose the questions correctly and to find understandable answers in practice.

Innovative products and processes

When redesigning materials, products or processes, chemical parameters change for bio-based raw materials such as wood, as well as for relatively homogeneous materials such as plastics. For example, by-products occur through conversion or oxidation, which can lead to emissions, leaching or visual defects. Changed polarities cause fogging of surfaces or lead to changed sorption behaviour. Our analyses are as unique as the problems that arise. Inspired by normative processes and the current state of research, we establish tailor-made analyses and support you from development through to quality assurance.

Ingredients and extractives

Wood, bark, energy crops, agricultural residues, residues from food production and other renewable raw materials are the basis of the biorefinery. The targeted extraction of phytochemicals can be of great benefit since it shortens complex synthetic routes in the chemical or pharmaceutical industry. For reasons of sustainability, macromolecules such as starch, flavourings, waxes or resins as well as tannins and lignin are also obtained and increasingly used as technical products such as pressing aids or binders. The evaluation of raw material potentials is key to all these applications in terms of quality and quantity. We provide the appropriate analytics and support you with engineering.

Our services


Product and process engineering

We develop new sensors and analytics based on cross-industry innovation, e.g. for wood drying, production of wood-based materials (particleboard, fibreboard, MDF, OSB, WPC), pellets and briquettes.

Process water in pulp and paper production

In cooperation with ÖZEPA members, we develop analytical methods e.g. for complexing agents, Sizing agents (ASA), bleaches (residual peroxide), or extraneous materials such as minerals and heavy metals.

Insulation without side effects

Insulations usually have a high surface area and corresponding emission behaviour. We provide analytical support for your product development and support engineering right through to perfect insulation.

Wood quality

In many products, chemical wood properties such as resin, fat, acids or sugar play a role. We support you in the selection of wood type or quality range.
