David: Our company ...

David:

Our company manufactures, installs and commissions biodigesters.

We convert everything that goes in to valuable products.

The digestate has value. Water that is removed is used for "A" Grade irrigation water...or we are able to quite simply take the treatment one step further and produce potable drinking water.

Some digestate is used as mulch and the remainder is used as fertilizer.

In one case we press the digestate and produce a reasonably dry pellet that is then used to fuel a gasifier and to produce electricity. In one case the heat from the gasifier is used to heat a controlled atmosphere green house to grow vegetables all year around. In another case we use the heat in a kiln to dry timber for immediate use, much faster than air drying.

We use Solutek to "super charge" the entire system. Solutek could be used as a standalone solution to clean and clarify effluent, this gives once again "A" Grade irrigation water.
