Do you know where we can source a chemical free weed killer for commercial landscape maintenance company?

The only chemical-free weedkillers are physical methods, such as hoeing or flame-weeders. The latter are available on a commercial scale but they use fossil fuels too. There are weedkillers based on acetic acid, which is a concenrated form of vinegar.
These alternatives physically destroy or burn the foliage of weeds which may recover, especially perennial weeds.
