Abstract:
Eutrophication and climate change are major global problems. The sea weed
Laminaria digitata
and the reed
Phragmites australis
have the potential to absorb nutrients and CO
2
during growth, as well as being a source of renewable energy in the form of biogas. The aim of this study was to evaluate
Laminaria digitata
and
Phragmites australis
concerning biogas production and nutrient recycling using a two-stage pilot scale process. The plant has a total volume of 430 L and consists of a hydrolysis bed and an up-flow anaerobic sludge blanket reactor (UASB). Two experiments were performed; one with
Laminaria digitata
as the sole substrate and one with a mixture of
Laminaria digitata
and
Phragmites australis
. Frozen substrates were placed in the hydrolysis bed and digestion was performed at 305 K during 70 days for
Laminaria digitata
and 100 days for the mixture of
Laminaria digitata
and
Phragmites australis
. The methane yield achieved was approximately 170 L kg
−1
volatile substances (273.15 K, 101.3 kPa) in both experiments. These results suggest that
Laminaria digitata
can be efficiently digested in larger scale and has the potential to contribute to a future sustainable energy mix, considering its relatively high methane yield when anaerobically digested as the sole substrate. Digestion of
Phragmites australis
needs further development to make use of its full potential.
