Perhaps by composting and recycling his own green wastes he would reduce his own need to use more additional nasty stuff. Burning and charring might be releasing even meaner stuff. Hopefully over time by reducing the chemical load maybe he get away from it almost entirely. Just thought.

Burning them would produce a smoke containing dioxins. Such pesticides may block the Composting process by killing the compost organisms. # What about the possibility of 1: Air dry the green waste to about 15% moisture content 2: Gasify the dried biomass 3: Cool the gases to about 250 F to 300 F, to allow re-formation of dioxins. 4: Filter the gasifier gas output through a bed of char, to capture any residual dioxins # Output products could be as follows: 1: A clean and safe fuel gas 2: Some clean char, suitable for garden use 3: A Waste Stream of char, contaminated with dioxins that could be treated further for dioxin destruction. This would be a costly process, but at least it has the potential to eliminate the Community health hazard.
