A Green Power House Grows in Cellulose Valley 
It is February in Montana, with nighttime temperatures dropping to around 20 F, but on this sunny morning, it is closer to Hawaii in the soaring interior of Algae Aqua-Culture Technology's Green Power House (TM). Standing over 40 feet high, the spaceship-like building is filled with light from its four, clear polycarbonate walls that taper upward toward a pagoda-like cupola. On its concrete floor are eight algae ponds, arranged like petals of a flower around most of its 5000 square foot floor space, and within these ponds grow the blue-green algae, (actually cyanobacteria), that harvest the nitrogen and carbon dioxide available in such abundance from the sky and from the nearby industrial processes of a functioning lumber mill--the F. H. Stoltze Land & Lumber Company (Stoltze). But what is rising here is not just a standard greenhouse, but an Earth House, a place where the struggling timber industry may find a new future by growing not just trees for lumber, but new soil grown from the residual biomass of its timber operations--new earth and organic soil amendments that will help recarbonize the carbon depleted soils of the Earth--all the while removing excess carbon dioxide from the air and helping industries to profitably reduce their greenhouse gas emissions.

F. H. Stoltze Land & Lumber Company (Stoltze) has been a fixture in the Flathead Valley for more than 100 years. A family owned firm, they've thoughtfully stewarded their lands and employees, growing trees the right way, and harvesting them in good time. With a view to their long-term future, however, they are always seeking innovations that will help them grow and thrive in a changing economy. At their mill site between the towns of Columbia Falls and Whitefish, they have recently provided major assistance to a small, new, cutting-edge business, Algae Aqua-Culture Technology (AACT), that is racing to return Stoltze and the forest industry to the forefront of technological innovation. "The AACT technology is clearly one of the most promising opportunities to help build, preserve, and diversify Montana's forest products industry economic strength in the renewable energy field," said Chuck Roady, Stoltze Lumber VP. (Stoltze has been very active in their own right, and Stoltze has just signed an agreement with Flathead Electric Cooperative to provide 2.5 Megawatts of power to the local power grid with a wood-fired, biomass generator.)

AACT has almost completed an innovative wood chip to energy and fertilizer processing plant that will initially employ about 9 people. As stated in a July, 2011 issue of BioCycle Magazine, AACT's proprietary process uses a greenhouse-based algae growth system and an anaerobic biodigester to transform a blend of the wood waste and algae into large amounts of highly valuable organic fertilizer and soil amendment. It will also produce high-value methane for power generation. Beyond that, the Green Power House is a wonderful antidote to Montana winters, since it provides a Maui-like, moist, year-round, low energy cost, off-grid, fossil-fuel-free, growing solution for high value organic crops.
AACT's Green Power House process offers an entirely new profit center to the forest and agriculture industries--make
money year-round by "growing" new soil. AACT's process has already
attracted the interest of the U.S Department of Commerce, and AACT
was one of five small- to medium- sized U.S. companies featured at the
recent Asia-Pacific Economic Cooperation Event in Honolulu.
is the story of how one set of the dreamers and doers in Western
Montana's Flathead Valley are helping to pave a new future for
Montana's "Cellulose Valley." It is a dream born out of
recognition that there
has to be a better way to produce jobs and energy--a better way that
replenishes the Earth and sustains the natural resources we so depend
on. The story of AACT is an example of the growing potential to
re-power the Flathead for a new energy economy.
AACT was started by "dreamers" Paul Stelter, co-owner of Alameda's Hot Springs Retreat and its geothermal hot water wells, as well as horticulturist Michael Holecek and Michael Smith, an animation, physical simulation, artificial intelligence and computer modeling engineer. The three experimented for a year with growing algae from Alameda's geothermal wells, but eventually realized the wells didn't have enough hot water to run a major biofuel production operation.
about this time I met Stelter, Smith, and Holecek. In trading stories
of our business efforts, Holecek noted that algae can also be
converted into fertilizer. This struck a chord. After sharing my
background having grown up in a timber industry family and having
seen the zealous desire farmers and foresters had for their piece of
the renewable energy revolution, the exciting realization for the
partners was that generating both fertilizer and energy from waste
cellulose and algae could be the value added revenue stream that was
desperately needed by timber companies and farmers alike. Shortly
thereafter in 2009, Mayre Flowers of Citizens for a Better Flathead,
as the Director of the three-day conference on Re-Powering the Flathead for a New
Energy Economy, introduced Smith to Stoltze's Chuck
Roady and Paul McKenzie. The three eventually agreed that the
innovative technologies that AACT was developing might allow Stoltze
to convert its waste wood resources into new heat and energy
resources for its plant and new product lines that would be less
affected by boom-and-bust economics.
