background-color: transparent; color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-style: normal;">I am thinking, if we ran the flue gas through water as a filtration process prior to discharge, could capture and reclaim those metals from the water later on, while treating the water to recycle back into the system and this would provide another waste product we could sell rather than simply discharging the waste into the environment.<span style="background-color:transparent;"> This is my own personal concept. I have yet to see a filtration system that integrates the water component but it makes sense to me and I think there is massive economic potential in developing a system like this. It would be a boon for the Universities to help develop a project of this nature. If it works we could launch it world wide to improve upon existing systems. </span></div><div style="font-size: 16px; background-color: transparent; color: rgb(0,

It still poses a risk to the Grand River and Erie in terms of nitrate/phosphate issues and it poses a risk to our wells. According to the report: Toronto's Future Weather and Climate Driver Study, we can anticipate 80% more rain in June and 50% more in August by 2040. </span></div><div style="font-family: arial, helvetica, sans-serif; background-color: transparent; font-style: normal; color: rgb(0, 0, 0); font-size: 16px;"><span style="background-color:transparent;"><cite style="color: rgb(0, 128, 42); font-family: arial, sans-serif; font-style: normal; white-space: nowrap; font-size: 14px !important;"><span id="yiv8674972746misspell-10"

style="background-color:transparent;">If these heavy rain periods over lap with our growing seasons or thaw periods, nitrate pellets might not stay in place if erosion happens. Pellets will wash to the lowest land points where water gathers in vernal ponds,
marshlands or tributaries and they can dissolve at higher concentrated levels in pools of water. That's just common sense. This could create issues of crop damages or environmental damages in low lying areas if the concentrations end up being too high. This risk can be mitigated if we apply nitrates/phosphate products at the beginning of a drip irrigation system rather than a direct field application. Also, bumping up wetlands in low lying areas help a great deal since natural wetlands can process 80 to 90% of nitrates and phosphates naturally. If we mandated the placement or protection of natural wetlands on farm fields in the lowest lying areas it is a good investment on protecting our groundwater supply, the Grand River and Lake Erie for the long term. </span></div><div style="font-family: arial, helvetica, sans-serif; background-color: transparent; font-style: normal; color: rgb(0, 0, 0); font-size: 16px;"><span style="

I also believe the current burning process can be improved upon if we integrate water filtration of the flue gas prior to discharge with the water reclamation crafted in. By building the better system of sludge to aggregate processing in Waterloo Region, with the Universities, with the assistant of the Water Quality Network and Ontario Stone and Gravel, the Ministries we could create an amazingly marketable product to showcase to the world. Integrate sewage treatment with water source protection, habitat creation, aggregate production, energy production and the offset of environmental
toxins. It's all
good. It's all there. I can see it. We just need the political will and money to make it happen. </span></div><div style="font-family: arial, helvetica, sans-serif; background-color: transparent; font-style: normal; color: rgb(0, 0, 0); font-size: 16px;" class="yiv8674972746yui_3_7_2_77_1377265968630_536"><span style="background-color:transparent;"><br></span></div><div style="font-family: arial, helvetica, sans-serif; background-color: transparent; font-style: normal; color: rgb(0, 0, 0); font-size: 16px;" class="yiv8674972746yui_3_7_2_77_1377265968630_536"><span style="background-color:transparent;">Build it right, the money will happen.
