Welcome to Grodan Is Stone Wool Recyclable? Yes! How Grodan and Walker Environmental Solved a Waste Management Challenge

Designed to Grow

More than 50 years ago, we noticed a tiny plant growing in a piece of abandoned stone wool on a building site. Just as it's designed to do, nature had found a way to grow. And it inspired us to design a system to support it – a smarter, soilless way of growing that we evolve, explore and refine continuously. A system that promises high yields of consistent, high-quality fresh food and medicinal crops to feed and treat the world's growing population.

Grodan and Signify collaborate to conduct low-energy tomato cultivation research with an expected savings on heat-input up to 40%

The trial started September 2023 at Botany and will explore principles of low energy growing under fully dimmable Philips LED lights. Focus will be on plant transpiration and nutrient uptake in a 260 m2 department fitted with active air de-humidification. This year's strategy is built on the knowledge gained from last year's successful tomato trial by Signify. By modelling the expected crop development and performance, both Grodan and Signify expect to reduce up to 40% on heat input by dimming the lights based on crop needs, energy prices, and outside light conditions.
