Circular economy in practice: Giving materials a longer life
Trade fairs are known for their inspiring exhibition stands and impressive spatial designs. At the Construction Services unit of Helsinki Expo and Convention Centre, exhibition stand construction is based on maximising the use of the same structures and materials across multiple events. The work focuses on reusing materials, reducing material waste, ensuring safe working practices, and continuously improving operations.
Building trade fairs and exhibitions requires materials, structures and expertise. The aim of the Construction Services of Helsinki Expo and Convention Centre is to make the most efficient use of existing structures, further develop material reuse practices, and identify new ways of working that support the long-term development of event production.
"When exhibition stands and displays are dismantled at the end of events, any materials that remain fit for use are recovered and utilised in new construction projects whenever possible. Our goal is to give materials as many life cycles as we can," says Jari Hallamaa, Production Manager at the Construction Services unit of Helsinki Expo and Convention Centre.
How Helsinki Expo and Convention Centre develops exhibition stand construction in line with circular economy principles:
1. Extending the lifespan of structures
Structures used at Helsinki Expo and Convention Centre events are designed to be reused at as many events as possible:
- Custom-made furniture is carefully documented so that it can be utilised in future events.
- Framed wall elements, support posts, wall panels and profile structures are reused across multiple events.
- Materials recovered from dismantled structures are utilised as efficiently as possible in new projects.
2. Reducing Material Waste Through Smart Design
A significant share of material efficiency is achieved already during the planning phase:
- Construction Services uses digital design tools, precise measurements and material optimisation methods to minimise material waste.
- In profile-based construction, the same structures can be reused across multiple events, reducing the need for new materials.

3. Continuously Evaluating Material Choices
Operating practices and material selections are continuously developed based on experience and new solutions:
- Construction Services uses water-based paints and continuously evaluates new materials for both timber construction and graphic production.
- Material choices take into account factors such as intended use, lifespan and opportunities for reuse in future projects.
4. Expertise and Safety Create Successful Events
Skilled professionals are at the heart of exhibition stand construction, and safety is an integral part of everyday operations:
- The Construction Services unit of Helsinki Expo and Convention Centre offers practical training opportunities for students specialising in surface treatment. This year, for example, ten students are working at Habitare.
- Staff receive training in recycling and waste management practices.
- New technologies, such as robotic measurement systems, are used to support both safety and efficiency.
- According to an employee survey, workplace safety is regarded as one of the greatest strengths of the Construction Services unit.
