The Wood Ash
There are two types of wood ash generated at the wood fired cogeneration power plant. Bottom or boiler ash is the ash
produced by furnaces after combustion; it is coarse and has very high carbon content. The fly ash is captured in the
plants multi clones and stacks and is finer in texture with finer carbon particles. The fly ash and the bottom ash are
mixed via screw conveyers at the plant and quenched with water before it is delivered to WAI's disposal site where the
mixed wood ash is stockpiled, uncontaminated with any other materials ready for recycling. Wood Ash Industries mixed
wood ash is highly alkaline with a pH of approximately 11.5, very high in carbon content and can potentially be
substituted for many carbon applications as well used in agricultural land applications.
There is a relatively high BTU content in the mixed ash which will facilitate wood ash reburning in smeltering and
similar applications that require carbon injection.

HIGH CARBON WOOD ASH
Biochar
Biochar is basically carbon produced from the pyrolisis of wood or other materials at temperatures that will produce a carbon by product. The wood ash that WAI receives on site contains 35% biochar produced by pyrolisis during combustion of wood and bark. It is suitable as a natural supplement to condition soils. It contains micronutrients, minerals and organic potash that supplements lawn, vegetable and plant growing needs. It has a high pH suitable for acidic conditions and also works well for odour and slug control and can be effectively used in composing. The high carbon wood ash material has been approved by the Ontario Ministry of Environment for agricultural land application.
Once burned Biochar is resistant to decomposition that will improve crop yield and sequester carbon in soils that will last for ages. When carbon is introduced to soils a resin is secreted by the carbon that reacts with the plants root system that increases the plants capability to absorb nutrients. Biochar when used in conjunction with nitrogen fertilizers increases crop yields and mitigates the release of nitrous oxide thus reducing the greenhouse effect The addition of Biochar prevents fertilizer runoff and leeching, allowing the use of less fertilizers, retains moisture, replenishes exhausted soils and fosters growth of soil microbes essential for plant absorption.

Rethinking biochar
High carbon wood ash is available in its present raw state, screened as per specifications and or powdered (crushed)
as per end user need and specifications. WAI is strategically located close to highway and rail access and can ship in
bulk within Canada and the United States. The high carbon wood ash is sold as a raw material under the classification
of a soil amendment from the disposal site.
WAI is presently seeking end users and strategic partnerships with a view to distribute high carbon wood ash in bulk
and smaller bagged quantities as a value added product. WAI encourages potential investors to contact us for future
product development.
