Comparative research reveals that the WAVE method is not the cheapest weed control method (chemical weed control is cheaper). But the same research shows that WAVE is certainly the most effective and environmentally friendly method of controlling weeds. By contrast with other weed control methods, WAVE is able to suppress the weed level instead of merely controlling it. WAVE is certainly a cheap method over the long term, as the weed pressure declines and less weed control then has to be done.
As WAVE does not damage paved or semi-paved surfaces, costs are saved moreover on repair work to these surfaces. WAVE’s added value lies not only in the fact that it provides qualitatively good weed control, but also that this is done in the most environmentally friendly and sustainable way.
