Research

The goal of this thematic research and development project is to build national competence in Estonia for the sustainable use of currently underutilised wood species and wood-based materials in construction. The project identifies engineering parameters for lesser-used wood types and develops sustainable production and building technologies. It also explores new applications for production residues, following circular economy principles in both design and technological development.

The project focuses on underutilised wood resources, including:

  • Hardwoods such as aspen, alder and birch.
  • Beetle-damaged and storm-fallen softwoods.
  • Industrial residues like CLT/glulam offcuts and veneer scraps.
  • Demolition timber suitable for reuse.
  • Modified and composite wood materials developed through chemical or thermo-mechanical treatment.

1. Mechanical valorisation of low-value and underutilised wood

This research topic focuses on enhancing the structural, physical and durability performance of underutilised hardwoods and beetle-damaged softwoods. Through material characterisation, mechanical testing, chemical and thermo-mechanical modification, and the development of engineered wood technologies, the project aims to unlock new construction applications for overlooked wood resources. The work results in engineering parameters, design guidelines and demonstrator elements enabling their safe, efficient and long-term use in buildings.

2. Circular use of industrial and demolition waste

This topic investigates the reuse and upcycling of wood residues, offcuts, and demolition timber in structural products and architectural applications. The project develops non-destructive assessment methods, separation and sorting techniques, circular design strategies, and detachable joints that support material recovery and multiple lifecycles. The goal is to minimise waste, extend the lifespan of wood resources and create low-carbon, resource-efficient material streams for industry.

3. Digital solutions for sustainable and circular design, production and construction

This research topic develops digital tools and workflows that enhance the utilisation of emerging wood materials and circular construction systems. This includes numerical simulation models, thermo-mechanical analysis, design configurators, generative design methods and integrated parametric pipelines supporting mass-customised, adaptable structures. The digital methods ensure better material efficiency, traceability and optimisation across the entire value chain—from resource modelling to production and assembly.
