The emergence of circular and bio-based materials play a significant role in building transformations due to their unique properties, renewability, and low environmental impact. As the construction industry seeks ways to mitigate its environmental footprint, low-carbon materials offer compelling solutions to reduce reliance on conventional, resource-intensive materials.

With increased focus on regenerative and circular economy principles, new types of materials are being integrated into transformation and adaptive reuse projects to reduce embodied carbon, promote healthier indoor environments and increase material circularity. For instance, bio-based products made from hemp, straw and wood have been used for centuries and are often breathable, humidity regulating and significantly minimize toxicity from artificial glues, binders and coatings.

Circular and bio-based materials also play a crucial role in reducing construction waste and promoting resource efficiency. Since they are often biodegradable or recyclable, they minimize landfill contributions compared to synthetic materials. For instance, wood fiber insulation, cork panels, and plant-based composites can be repurposed or composted at the end of their life cycle. In addition, by utilizing locally sourced materials, transportation emissions are also reduced, further lowering the environmental impact.

The aesthetic design potential of circular and bio-based materials contribute greatly to their growing popularity in building transformations. Architects and designers appreciate the unique textures, colors, and natural patterns that materials like rammed earth, reclaimed timber, and plant-based panels bring to interior and exterior spaces. Moreover, by incorporating recirculated and biobased materials, building transformations can embrace bioregional and biophilic design principles, fostering spaces that are functional, regional and emotionally enriching.

Despite their many benefits, the use of biogenic materials in building transformations faces certain challenges, including durability concerns, regulatory hurdles, and cost implications. Some biogenic materials may require additional protective treatments to ensure longevity, particularly in harsh climates. Additionally, building codes and regulations in many regions are still adapting to the use of alternative materials, posing barriers to widespread adoption. However, as research and innovation in biogenic materials advance, new techniques are emerging to enhance their structural performance and fire resistance, increasing their viability in diverse construction scenarios.
