Agreka Build is a climate tech company reimagining the future of construction and agriculture through circular innovation. We transform agricultural waste—specifically wheat straw, one of the world’s most abundant and underutilised residues—into high-performance, regenerative building materials. Our flagship product, WHEATEX™, is a natural fibre insulation board made entirely from 100% waste wheat straw, without a drop of synthetic binder. It’s carbon-negative, breathable, biodegradable, and designed to meet modern performance standards while restoring ecological balance across the value chain. By bridging material science, rural supply chains, and sustainable design, Agreka Build is not only decarbonising buildings but creating new economies rooted in zero waste and climate resilience.
Hello, I'm Antoinette Oni—an award-winning architectural designer and CEO of AGREKA Build, where I lead the development of WHEATEX, a circular, bio-based insulation made entirely from waste wheat straw. With over a decade of experience in architecture and sustainability, my work focuses on regenerative design and material innovation.
I’m passionate about decarbonising the construction industry, tackling fuel poverty, and shaping a healthier, more equitable built environment through climate-positive design.
