<div dir="ltr">I have the following suggestion: Biphasic digestion, in which the first phase (anaerobic) converts the water hyacinth into lactic acid. The lactic acid is then fed into the regular anaerobic digester. This would be an ideal solution for not only
water hyacinth, but for all biodegradable material. One need not even segregate the feedstock, as the non-digestible matter would remain in the first phase, which can be periodically opened and cleaned.

Hi Alex and other Listers<br>
<br>
I have an article on the digestion of hyacinth that I downloaded years ago.<br>
Anyone interested in it, please email me and I will send you a copy.<br>
<br>
Kind regards<br>

Dear Dr. Karve,<br>
<br>
Could you share any loading rates or retention times related to water<br>
hyacinth?<br>
<br>
Also, currently the coast of Mexico is in the middle of a massive seaweed<br>
bloom, and it is clogging up all the beaches and ports of the coast. Has<br>
anyone ever worked with a sea weed? Obviously it would a high salt content,<br>
and I suspect some undigestable portions, but maybe the energy production<br>
could break even with efforts to clean up the area. Any thoughts or<br>
experiences?<br>
<br>
Best,<br>
<br>
Alex<br>
