In the world of construction, the concept of radical acts of repair is gaining traction, and Sydney-based studio Second Edition is at the forefront of this movement. Founded in 2021, the studio aims to reduce construction and demolition waste by exploring innovative ways to salvage and reuse materials. In this article, we delve into the challenges and opportunities of material salvage and reuse, as well as the importance of collaboration and observation in the construction industry.
The Financial Viability of Material Reuse
One of the key challenges in material salvage and reuse is making it financially viable. According to Shahar Cohen, one of the practice founders, it's a balancing act that requires careful documentation and knowledge of material destinations. While reclaimed materials can be cost-neutral compared to purchasing new, the labor cost to process them often exceeds the initial savings. To address this, Second Edition focuses on building efficiencies into other aspects of the business, allowing them to invest more time in material reuse processes.
Repurposing Kitchens and Other Components
When it comes to kitchen renovations, Second Edition takes a critical lens to the waste generated by frequent replacements. Amy Seo, the other practice founder, explains that older kitchens without carcass systems are often easier to work with, as the structure itself is worth retaining. Modern joinery production, however, can make it challenging to match and repurpose existing components.
Appliances, surprisingly, are another item that can be easily repurposed. Second Edition salvages appliances that are barely five years old and still perfectly usable, finding new contexts for them in their projects.
Complications in Disassembly and Reuse
Full demolition, often requiring mechanical processes, can complicate material salvage. Hand or slow deconstruction becomes cost-prohibitive, and the willingness of clients to invest in deconstruction is crucial. Second Edition's success in salvaging materials from a North Bondi house built by Robert Plumb Build is attributed to their close relationship and genuine interest in deconstruction.
Retroactively embedding salvaged materials into a design is another challenge. Seo emphasizes the importance of considering material reuse early in the design process to avoid rework and client resistance.
Scaling Render and Terrazzo Methods
Second Edition has experimented with renders and terrazzo made from crushed stone offcuts, a bespoke method at this stage. Cohen believes that these processes can be scaled and replicated, but finding the right contractors for crushing and screening is essential. Precision is critical to ensure the material performs properly as a render.
Overstock and Seconds Materials
Surry Hills Terrace, a recent project, utilized overstock and seconds materials, which are often easier to work with due to organized suppliers and known quantities. Seo highlights the importance of considering material quirks, such as color variation, to ensure successful detailing and installation.
The Materials Bank and Appetite for Reuse
Second Edition runs a materials bank, accepting sourcing requests. Cohen notes a significant growth in the appetite for reuse, but resistance still exists, primarily from clients who prefer new materials due to perceived performance and warranty concerns. Mid-range finish levels are where reuse becomes financially viable, and builder liability is a concern that can be addressed through education and understanding.
Collaboration and Knowledge Sharing
Collaboration and knowledge sharing are vital to Second Edition's practice. Seo emphasizes the importance of close relationships with builders and subcontractors, as well as direct communication with them. Paying attention to what's already out there and translating it into design is a key part of their process.
Future Waste Streams to Investigate
Second Edition is focused on two waste streams: papers and plastics, and metal offcuts. While they've made progress with marble, timber, and brick, the potential for repurposing plastic waste and utilizing metal offcuts for small fixtures and fittings is significant. The recycling process for metal offcuts is carbon-heavy and often involves shipping offshore, making direct utilization a more sustainable approach.
Advice for Integrating Material Salvage and Reuse
To those interested in integrating material salvage and reuse into their work, Second Edition offers valuable advice. Seo suggests speaking to clients early and emphasizing the potential for value addition, both aesthetically and narratively. Early communication with builders is also crucial to ensure everyone is on board, avoiding surprises and rework.
