I agree.

I was simply referring to the tendency of industry to compromise quality 
and safety in favor of big profits from converting questionable biomass 
material, possibly industrial waste of some kind into biochar,
selling it for as much as possible and wussing out if it results in 
pollution affecting end user or the environment. Don't know what 
materials these might be but with a little research you might find 
materials that might be otherwise be landfilled or stored on site 
somewhere long term resulting in offsite pollution...

Can municipal waste, i.e. garbage, paper, cardboard, landscape 
trimmings, leaves and the like be processed into biochar then used 
alongside mulch and compost, also produced in municipal or county 
landfills, in municipal, county, state and federal landscape plantings 
in parks, along highways and around buildings?

I am a big advocate of making and using biochar as long as it is done
using processes that recycle most or all the flammable gases and emits 
little or no smoke; this for the sake of the person making the biochar 
as well as for everyone else downwind and the environment. Of course 
uncountable numbers of wood stoves are used each year, most of which 
pollute. Still, it would be good to set a precedent by promoting clean 
biochar making from the start. So, are there homebrew stoves that can 1) 
produce space heat when needed 2) cook food or heat water 3) make 
biochar. Seems water heating and biochar making could go hand in hand,
using water heating coils with storage in tanks overhead by convestion;
gravity flow for deliver when and where needed.

Biochar is a miracle material but making it is no trivial matter.
