Green Logs are fireplace logs made from compressed Giant
King Grass, and are said to have a very low carbon footprint
As winter tightens its icy, gloomy grip on the Northern
Hemisphere, many of us are turning to our fireplaces or
wood-burning stoves for physical and psychological warmth.
Unfortunately, however, burning wood releases carbon into the
atmosphere – a conundrum for people who want to minimize their
CO2 footprint but still stay warm. U.S. company VIASPACE Green
Energy, however, has just started selling a product that it
claims will provide customers with fire fodder, while being
almost carbon-neutral: fireplace logs made from compressed Giant
King Grass.
VIASPACE’s Green Logs are made from grass grown and
processed at the company's facilities in China. They incorporate
a natural wax binder and fire starter, light in less than three
minutes, burn for up to five hours, and are said to have a heat
output similar to that of wood... but how are they low-carbon?
“If the plant is burned, carbon dioxide is released into the
atmosphere,” CEO Dr. Carl Kukkonen told Gizmag. “However, it is
exactly the same amount of carbon dioxide that was removed from
the atmosphere during growth, and the next crop will absorb the
same amount of carbon dioxide.”
Trees also absorb CO2, of course, but they grow much more
slowly than Giant King Grass – whereas a tree takes decades to
reach maturity, the grass can be harvested every four to six
months. Kukkon admitted that fossil fuels used to process and
transport the product do add some excess carbon to the
atmosphere, but the same can be said about other heating fuels
such as wood and coal.
“We believe that Giant King Grass can play a very important
role in clean energy for the world,” he said. “Green Logs are a
first product and the place where we can touch consumers
directly. Giant King Grass can be burned in power plants to
generate clean electricity and can be used to produce nonfood
cellulosic biofuels such as ethanol and green gasoline.”
The first shipment of logs is mainly going to retailers who
want to see how the product sells, although some cases are
available direct to consumers on
Amazon and
eBay. Unfortunately, they're not yet quite as cheap as wood
– a pack of six 5-lb (2.27-kg) logs will cost you US$22 or
$29.95, plus a substantial shipping fee.
