Hi All, I haven’t contributed to this group yet, but am following because we have a group in Idyllwild, Calif, where we are exploring ways to ecologically thin the forest to reduce the risk of wildfir

Thanks Tom, certainly research has happened over the last 50 years, although none of it really seems to contradict what I said, as it was at a base level. I guess that it is not so surprising that a w

Hi Kevin, I first heard of PFAS about 25 years ago when they were found to be polluting a lake near an Air Force base in Michigan. They were used in fire fighting foam and in Teflon non-stick cookware

The colloidal solution is intended to suspend extremely finely-ground BC. It was mentioned in one of the Science Direct studies. I have not yet gotten into this topic in detail because it's a little o

Hi Rob You have to do an adsorption test with a biochar to convince people. Use a local University if you dont have the facilities. REgards Stephen

#pfas #pfos

I know of effective treatment systems involving biochar used to enhance phytoremediation of PFAS. In such a system, rapid adsorption by biochar and relatively slower rhizodegradation contribute to the

Stephen, That's great.......Your feedback causes me to ask more questions.... 1. Does the charring process itself destroy PFA substances in the biosolid phase ? 2. How, when and where would you deploy

#pfas #pfos

Hello Rob. I assume you are talking about water filtration? Make sure you take a BC that works for your problem. I doubt you'll find one BC that works efficiently on lead and on PFAS at the same time.

I am working in Vermont on PFAS -- we have a huge problem for a small state. The company I am working with uses activated charcoal (not biocarbon) in a colloidal suspension. The company told me they p

Hi Mike The group of pople I work with have done a lot of work on moping up PFAS with biochar and I have developed some proprietary hardware to breakdown the PFAS that is in the biochar. Regards Steph

does the manure charring. process degrade PFAS....? PFAS. are called forever chemicals... if so, do manure char makers validate/verify this...? Sent from my Verizon Wireless 4G LTE smartphone
