This research transforms wood waste into bio-based protection agents for construction timber. Using green extraction methods and enzymatic modification, natural compounds are isolated and enhanced to replace toxic chemical treatments. Laboratory testing confirms their antimicrobial, antioxidant, and weather-resistant properties, supporting sustainable wood protection and circular economy principles.

This research tackles concrete’s carbon footprint by replacing Portland cement with locally sourced natural pozzolans. By calcining and testing South Island geomaterials, the work demonstrates a low-cost, carbon-free alternative that maintains strength and durability while reducing emissions and construction costs.
