Short answer

Integrate strategies for timber reclamation and reuse into design and construction projects by advocating for policy changes, developing new grading standards, and fostering collaborative supply chains.

Field: Sustainability
Source: Journal of Cleaner Production (2025)
Method: Qualitative research through systematic interviews.
Evidence: Strong effect

Reclaimed timber from existing buildings can be effectively repurposed into mass secondary timber (MST) products, but requires new supply chains, deconstruction skills, and certification standards to overcome current barriers. This sustainability research insight is drawn from a 2025 study published in Journal of Cleaner Production. Using Qualitative research through systematic interviews., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Integrate strategies for timber reclamation and reuse into design and construction projects by advocating for policy changes, developing new grading standards, and fostering collaborative supply chains.

Mass Secondary Timber: Unlocking the Circular Potential of Reclaimed Building Wood

Journal of Cleaner Production · 2025

Key Findings

01There are minimal technical barriers to salvaging structural timber; challenges lie in deconstruction time, logistics, reconditioning, and the absence of an established reuse supply chain.
02Developing a value chain for reclaimed timber is feasible and presents significant opportunities for sustainability.
03Policy, legislation, and standardized grading/certification methods are crucial for facilitating timber reclamation and reuse.

Application

Design takeaway

How to apply

When specifying materials for new builds or renovations, actively seek out suppliers of mass secondary timber or investigate the feasibility of salvaging timber from the project site or nearby demolition sites.

Project actions

01Investigate local demolition sites for potential timber salvage opportunities.
02Research existing standards for grading and certifying reclaimed timber, or propose new methods.

Method & Evidence

AimWhat are the key barriers and opportunities for salvaging structural timber from existing UK buildings and repurposing it into mass secondary timber (MST)?

MethodQualitative research through systematic interviews.

ProcedureConducted interviews with key stakeholders across the UK timber construction supply chain, including demolition contractors, to identify challenges and potential solutions for salvaging and repurposing reclaimed timber.

ContextConstruction and demolition waste management, circular economy in the built environment, UK timber construction sector.

Variables

IV["Stakeholder perspectives on barriers and opportunities for timber reclamation."]

DV["Identification of strategies for salvaging and repurposing timber.","Assessment of the feasibility of developing a circular value chain for timber."]

CV["Geographical focus (UK construction sector).","Type of material (structural timber elements)."]

Strengths & Limitations

Strengths

+Addresses a critical gap in current practice regarding timber circularity.
+Involves key industry stakeholders, providing practical insights.

Limitations

Access to demolition sites for direct assessment might be restricted. Developing new grading systems requires significant technical expertise and testing.

Reliability & validity

The validity of the findings relies on the representativeness of the interviewed stakeholders. Reliability could be enhanced through triangulation with existing data on construction waste and timber markets.

Think critically

To what extent can current deconstruction practices be adapted to facilitate timber salvage, and what innovative technologies could aid in the efficient reconditioning and grading of reclaimed timber?

Design Principles

"Prioritize material circularity by designing for deconstruction and establishing robust systems for the recovery and repurposing of valuable building components."

This research highlights a significant opportunity to reduce construction waste and promote a circular economy within the building sector. By understanding the challenges and proposing actionable strategies, designers and engineers can advocate for and implement more sustainable material sourcing practices.

What This Means for Your Design

We can reuse wood from old buildings to make new wood products, but we need better ways to take buildings apart carefully, fix up the old wood, and create a system for selling and using it.

Paragraph starter

This research by Godina et al. (2025) highlights the significant potential for repurposing timber from existing buildings into mass secondary timber (MST). While technically feasible, the widespread adoption of this practice is hindered by logistical challenges in deconstruction, the need for reconditioning processes, and the absence of a structured supply chain and certification for reclaimed timber. The study emphasizes that policy and legislative support, alongside the development of grading and certification methods, are critical for establishing a robust circular value chain for timber construction.
