<div dir="ltr">Helo Dr.Thomas and Tom Reed<div><br></div><div><br></div><div style> According to the published report , the charcoal obtained by slow pyrolysis ate lower temperature are not as effective as biochar made at high temperature .This can be due to the partical size .Let us see how your experimental results can agree with this or not .Experiemnetal results can solve this problem well</div>
<div style><br></div><div style>Thanking for sharing your expert views before experiments rather than afer the results obtained , as most here usualy share resukts here , also analyse this along with other.This list with very large list member , some lIke TOM and Dr. Thomas are realy not only have good practical experience , as they gained after travel a long distance participating seminars , conferences but also they find time ,to share the knowledge here.Thus the new comer here to this list can learn very quickly from the well madem from valuable debate , some are realy very critical too, conventional</div>
<div style><br></div><div style> Very glad that Thamos Reed as active as used to be like TOM Reed to make the list debate very dynamic one , online , colaborative , multimedia.Thanking all the team work who make this possible as an well organised globalised forum , as not the topic has relevant trend , but also the we can all make the small bioenergy from waste as more practical too </div>

Most people think Charcoal has to be made in heated kilns, but you can be in business today much more simply. Once lit, dry fuel will auto-pyrolyse using the burning cellulose to pyrolyse the 20% lignin which converts to charcoal.</span></div>

With a 1.5V fan you can get a really beautiful, intense, clean burn. Without the fan, you still get a pretty clean upper gas flame and a can full of charcoal. </span></div>

I’m a soil fanatic and want to know more. I was delighted to see that you recommend mixing biochar with compost. I’m going to a three-day compost school at the Rodale Institute in Kujtztown, Penn., later this month. I already spray our pastures with raw milk, molasses, liquid fish, liquid kelp and several other amendments. I’m delighted with the results. I have a number of friends that use compost tea very successfully and while I’ve sprayed a little tea, I’ve not done much because I’ve not had any confidence in my ability to make good compost.<u></u><u></u></span></font></p>
