Hackathon – Hardwood and process optimization of regional value chains in timber construction

Hackathon – Hardwood and process optimization of regional value chains in timber construction

digitize wood and the Institute for Entrepreneurship and Innovation Science (ENI) are organizing a hackathon on the topics of hardwood and process optimization in timber construction from May 23-25, 2023. The aim is to develop new ideas and concepts for the regional value chain in timber construction against the background of climate change. In the future, fewer softwoods and more hardwoods will be usable for timber construction. Since these differ greatly in some respects, the value chain as a whole must be reconsidered and adapted.

Info and Registration

Target groups and previous knowledge

The hackathon is open to all interested parties and is also offered as a course for students of the University of Stuttgart. (For students of the Uni Stuttgart the registration in Campus is already closed).

Previous knowledge of coding or wood construction is not required, much more curiosity and interest are needed and the willingness to work in interdisciplinary teams and get involved with the topic.



Date: May 23 – 25, 2023

Language: German / English

Registration: required via eventbrite

Timber construction

It is obvious that the construction industry must also become more climate-friendly: it is currently responsible for about 40% of global resource consumption, 40% of energy consumption and 50% of waste. An ecological alternative to the conventional steel-concrete buildings we use is timber construction. This is because wood is renewable and binds CO2 as it grows, which is stored in the stem – even when the wood is used as beams in a house, for example. In addition, it is regionally available and can be recycled.



In recent decades, spruce trees have been the main species grown for economic use in the forest, as they grow quickly and their wood has excellent properties for timber construction. The entire value chain in timber construction has therefore been geared towards the processing of softwood.

However, as a result of climate change, spruce stands in Germany are suffering major damage. Heat, drought and pest infestation are causing the trees to die, calling for what is known as forest conversion. This means that in the future, many different tree species will have to be planted in order to increase biodiversity and thus make the forest more resilient.

In the future, this will mean that fewer softwoods and more hardwoods will be usable for the timber construction industry. However, since hardwoods and softwoods differ greatly in some respects, the value chain as a whole needs to be reconsidered and adjusted. For example, hardwoods cannot easily be sawn with the same saw as softwoods because they are much harder. Transportation and logistics of different woods also need to be organized.

Therefore, for the hackathon, these are some of the questions that arise:

- What are the differences between hardwoods and softwoods and what are the impacts at which point in the value chain?

- Which effects represent a problem and can be dealt with within the hackathon through a solution concept?


Process optimization in timber construction

Robotics and automation offer great potential in timber construction to make building more efficient and to meet the need for 400,000 missing apartments per year in Germany alone, while also making up for the shortage of skilled workers. However, the introduction of new technologies also poses a number of problems: In Baden-Württemberg, there is the peculiarity that woodworking companies have an average size of ten people. This means that the investment and training costs of automation are usually too high for them.

For the hackathon, therefore, these questions arise, among others:

- How can small businesses benefit from robotics and automation?

- Are there opportunities to network with each other, to pool resources?

- How can data exchange be organized?



Institute for Entrepreneurship and Innovation Science (ENI)

The institute promotes entrepreneurship in research and teaching with a cross-faculty approach that brings together theory and practice. This includes, among other things, the interdisciplinary connection between technology, science and management as well as the cooperation with internal and external partners, e.g. Technology Transfer Initiative, ARENA2036, STARTUP-AUTOBAHN, Cyber Valley, Gründermotor, quer.kraft e.V., etc. The institute is a member of the Faculty 10 for Economics and Social Sciences, as well as a co-opted member of the Faculty 7 for Mechanical Engineering.
