[QUOTE="Fowler VF, post: 6454914, member: 57664"] Our biochar is a co-product of gasification of virgin wood chip. The chip is "cooked" in a reactor vessel with a limited amount of air, gas comes off as Carbon Monoxide and Hydrogen and leaves behind a small amount of carbon as the biochar. Typically we would see around 2 to 3% of weight of the incoming wood ending up as char. We could produce a lot more char by adjusting the process times and the gas production, but for us the gas is the main focus. We use the gas to run engines for electricity production. The char comes off as a fine powder/ granule, think of agricultural lime, only filthy black. The char will still burn, its carbon, so we have on times used it as a fuel in biomass boilers. As has been stated, the particle size isn't important, its the massive surface area on a micro scale that is its key. In soil it provides a huge surface area for bacteria etc to shelter in and work from and also gives micro pores for adsorption of nutrients. Zeolites have similar properties, in another life I did trial work on adding zeolites to composts and chicken manure to improve nitrogen retention. Zeolites are a volcanic rock formation, and have a long history in agriculture.
