Not at all.
One of the most common questions we’re asked is about leaching — especially when people are growing food. It’s a fair concern. If we care about soil health, we need confidence in the materials that surround it.
Independent laboratory testing under EU soil and groundwater regulations assessed the material for heavy metals, PAHs, PCBs and mineral oil hydrocarbons. The results were either extremely low or below detectable levels, all comfortably within strict environmental limits, including standards applied to soils used on children’s playgrounds
What this reinforces for us is that when flexible plastic waste is transformed into a dense, rigid, long-life structure, its environmental behaviour changes. It is no longer subject to constant abrasion or movement. Instead, it becomes stable infrastructure designed to remain in place for decades — keeping existing material safely in circulation rather than allowing it to fragment or be discarded elsewhere.
