Municipal weed control can be damaging for the environment when herbicides are used. It can also create damage to the infrastructure when it is done mechanically. Heatweed technologies has developed a system that uses sensors and super heated water to kill the weeds. It also kills the root system so weed control can be done less frequent which saves money on maintenance. The sensors detect the weeds and determine where the water should be sprayed. Energy use is minimized by this focused approach.
