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.

Environmental Product Declarations (EPDs)

We are proud to announce the completion of our Environmental Product Declarations (EPDs), a testament to our commitment to transparency and sustainability. One for our Galv panel and one for our Colour panel.

What is an EPD?

An Environmental Product Declaration (EPD) is a certified, independently verified summary of a product’s environmental impact over its entire life cycle. It evaluates:

• The materials extracted from the earth.
• Energy used in the production, transportation and installation.
• The environmental impacts of using, disposing, or recycling the product.

The EPD covers a range of environmental indicators, including the potential for carbon emissions, air and water pollution, and depletion of natural resources. Based on international standards (ISO 14025 and EN 15804 for building materials), our EPD is independently verified, making it a trusted and reputable source of information. It is recognized by industries, companies, and governments, and is often specified in tender documents and contracts.
