Bio Gas - Duckweed..
A tiny aquatic plant with enormous potential for agriculture and environment.
Lemnacaeen are one of the fastest growing plants organisms in the world.
Throughout the world, and particularly in Asia, farmers have harvested naturally produced aquatic plants for a number of purposes including animal feed, green manure and for their family feed resources. The best known of these include the free floating plants; water lettuce (Pistia), water hyacinth (Eichhcornia), duckweed (Lemna) and Azolla and some bottom growing plants.
Duckweed need less space then any other cultivated plant on earth. For same harvest yield they need only 20% space of that of corn and in comparison to soja it even is only one tenth!

Because it's high content of proteins (33-40%, fibre rate 5%-15%) duckweed suits perfectly as fodder plants. Duckweeds proteins do have higher concentrations of trace elements, essential aminoacids, Lysins and Methionines as most other plants proteins - resemble animals proteins better then any other. Duckweed from heavy metal free waters are without hesitation fit for human consumption.
Under optimal conditions they double their space within less then 2 days.

So 1 m2 can cover 1 ha within about 14 days.

Water Cleaning Ability

Duckweed is optimal for biological agricultural and communal sewage purification.

Concentrations of 20-60 mg/l NH4N will be processed without any problem.

Resolving and denitrification of NH3 up to 73%.

Up to 42%-67% of total Nitrogen,
mainly Ammonium and 56%-95% of Kjeldahl Nitrogen, (Kjeldahl-nitrogen:

Total Kjeldahl Nitrogen is concentration of total N as total amount of organic bound N and Ammonium-N; TKN = org.N + NH4-N; [mg/L].

up to 75% of total Sulphur

up to 9 kg salt/ha/d and up to 93% suspended organic substance will be taken out of the water per day.
