Our Commitment to Waste Reduction
At KOROK, we focus on reducing waste and being environmentally responsible. Our efficient manufacturing processes and thoughtful product designs help us provide reliable, high-performance solutions.
Reducing Waste
Made to Order
Our panels are manufactured to order, ensuring minimal waste. This custom approach means minimal off-cuts and no unnecessary waste, as each panel is designed to fit specific job requirements perfectly.
Fully Reusable
KOROK panels are designed for reuse. They can be taken down and reassembled multiple times, making them ideal for reconfiguring warehouse or retail spaces. This reusability significantly enhances their ecological friendliness, reducing the need for new materials and minimising waste.
Fully Recyclable
When a KOROK panel reaches the end of its life cycle, it doesn’t need to end up in a landfill. The panels can be disassembled for recycling: the concrete core is crushed and repurposed, and the steel casing is recycled. This closed-loop process ensures that our products contribute to a sustainable future.
