[Stoves] LPG import in India

[Crispin Pemberton-Pigott]

The offgas idea is fine but there aren't many uses for it dispersed in rural Namibia. Wood is expensive to haul and there is little they cam do with a lot of heat in the Kalahari or Namib deserts.

The chemistry lesson is interesting. I was not aware that the dioxin was not a principal ingredient of defoliants. The stuff contains TCDD dioxin. Why is it in there? By accident?

Even better if the energy from the pyrolysis offgas can be made use of.

I have seen large areas sprayed with dioxin to kill it – whole farms of it. Namibia is about the last place on earth where it is possible to apply agent orange. There are about 50,000 tons of it left and someone has to eat it….I guess…

Well yes but the intention was presumably to  spray it with synthetic auxins,  to trigger unregulated growth in the angiosperms. These were 2,4,5 T  and 2,4 D in agent orange but it was a cheaply manufactured formulation and the dioxin was an unintended high  contaminant of the mixture (apparently there is always some dioxin produced in the synthesis but  agricultural formulations had much less). I had the job of applying 2,4,5,T in my youth.
