Impact Bioenergy creates portable food digester

April 9, 2014, Seattle, Wa. – Seattle-based Impact Bioenergy
has created a unique technology that enables institutions and campuses to
generate energy from their own food scraps and paper products.

The company has developed a proprietary portable bioenergy
generation technology, called model AD185, which eliminates the need to
transport waste by processing it on-site. The technology uses anaerobic
digestion to extract biogas from the feedstock. Nutrient-rich compost is the
ultimate end-product, after the biogas has been extracted. The AD185 requires
less than 400 square feet of ground space. An energy storage unit (320 square
feet) can be added for peak demand cycling. The equipment fits in an urban
setting and includes features like gas lighting to visually engage passers-by
with a compelling illustration of the energy value of food scraps. The system
is pre-fabricated and can be installed in a single day with simple connections
to building wiring, water, and sewage systems.

The novel and unique aspects of the design include a
skid-mounted food waste recycling and preparation system, digester, and power
production unit. The AD185 is rated for a waste input of 1,000 lbs. per day
(peak 2,000 lbs. per day) with 48-day

residence time. It is a completely portable bioenergy plant
that can be configured for electrical output or biogas supply to an existing furnace
or boiler. Electrical output on a base-load 24-7 basis is 11.7 kW, with peak
output at 35.1 kW. Odor is captured and treated with state-of-the-art odor
control technology including biofiltration, carbon filtration, and atomizing in
a fully enclosed system.

Impact Bioenergy has offices in British Columbia,
Washington, and Oregon selling localized bioenergy technology, representing a
paradigm shift in both waste management and renewable energy production.
Impact’s systems eliminate the costs and environmental impacts associated with
the disposal and hauling of organic (carbon-based) wastes to distant landfills
by converting them into heat, electricity, vehicle fuel, and soil amendments
on-site at their point of generation. Impact’s line of bioenergy units is
manufactured in the Pacific Northwest to ensure quality, value, and support for
local business. In addition to bioenergy products, Impact offers waste
diversion and energy consulting services. Impact’s Chief Operating Officer
Connor Folley states, “Impact’s technologies provide a rare opportunity for
organizations and communities to reduce costs and their environmental impact.
We empower our customers to simultaneously ‘Do Good’ for the planet and their
bottom line.”
