My understanding is that dioxins and furans, being halogenated, are a byproduct of burning the halogenated plastics - PVC, etc.
For PP and PET, there are no such halogens present and thus any products of incomplete combustion will be hydrocarbons (nothing worse than what is produced from the low temperature combustion of cigarettes...

How naive am I being?

Ooow, I did this last winter for the rabbit-proof perimeter with Black locust poles.  Thinking I was pretty smart, I considered testing my innovation by letting them sit for a hunnerd years, then filing for a patent...

In previous years I have juiced my Yacon (another inulin loaded tuber,), then boiled it down to a syrup (which has a lovely rich earthy taste.)  As last winter I lost the majority of the Yacon growing tips to some hard frosts the thought occurred this year that I could try the same process with Jerusalem artichokes (as they're known in these parts.)  I haven't done it yet but will hopefully find some time before the end of winter.  

Just tried to access the website for the first time in a while and was greeted with a strange prompt specifying that as I could't be reached through my saved email, it must be changed.  That's weird as I haven't blacklisted permies@permies.com and come to think of it, I haven't seen any of the dailyish emails for a while so I checked and the last one I got was on the 3rd Oct.  I had to change to an email that I don't really check regularly before I could even access the site to query why this has happened?
Any suggestions?  TIA

I've been collecting the thistle down to use in the rendering of my RMH, gives a really smooth finish.  
It got me wondering if it could be used as insulation for quilts and such..

They're going to hate on me anyway, may as well obtain a yield!

What a great way to get the word out about RMH.

10,000 people saw your video and maybe one or two may build one.

You can include me in the headcount.
Andrew's 13-part series was invaluable for the construction of mine..

Our dear friend entropy...

While being a very willing proponent for the RMH, I notice that there is a dearth of resource on the emissions with regards to products of combustion at high temperatures, specifically nitrogen in its varied oxidation states.  An appropriate analogy would be to make would be with the modern diesel emissions standards - while there is little visible smoke, as the diesel engine is running lean (and thus hot) NOx are greater than the cooler gasoline (or petrol for UK folk) engine.  In recent times, this has been modulated with ADBlue.
Is there any useful information out there on this issue?
