[Digestion] Water hyacinth

[Anand Karve]

Dear Alex,
we used a 1000 litre digester and introduced into it about 20kg
macerated water hyacinth once every day. It took our system about
three days to consume the daily dose of 20 kg water hyacinth and we
obtained daily about 600 litres biogas. The biphasic system is still
being tested.
Yours
A.D.Karve
