      I haven't had any trouble with water hyacinth springing up again after composting.  Although I've never put my compost into a lake.  Crocodiles and hippos impede the harvesting and care needs to be taken, such as using a long pole with an adapted end to scoop the Hyacinth out.  A strong boat that hippos can't flip over would be important.
      The briquette making still goes in some areas, but not very strongly to my knowledge.  The machines are a pretty big chunk of capital and are not the simplest things in the world, paper is not a large commodity, it is a lot of work to make them, and the groups which make them have difficulty selling them to people.  Personally, we make briquettes from just the paper without a machine and really like them.  We read about it in the Footsteps magazine by Tear Fund UK.   It works well for us because we get a lot of scrap paper, it isn't something that can be utilized everywhere in Malawi.

      Dear Cathy and all,

      Remember, Richard Stanley, the guy who was trying to introduce the low
      density briquettes made from partially composted agricultural waste.  While
      we were in Malawi he also came up with some briquettes made from water
      hyacinth.  Seems as if they would have worked but,

      The story I heard was there were several objections:
      1.  It was too dangerous to harvest the weed because of crocodiles etc.
      (What isn't dangerous in Malawi?)
      2.  The seeds did not break down in the partial composting process and
      someone was afraid if the briquettes were transported far and wide the seed
      would be spread.  (Probably a legitimate objection)
      3.  and, What about environmental damage if all the weed was harvested?  (I
      thought the weed was causing environmental damage)

      Has anyone heard of further progress with this briquette activity?

      Also, there was a problem in the lower Shire with the weed because of the
      demise of hippos.  It seems the hippos were the only creature strong enough
      to break trails through the stuff once it got established.  Without the
      hippos the water was stagnating,  losing oxygen, causing fish to die.  Any
      further word about the lower Shire?

      To anyone of you who might be interested in that water hyacinth problem
      that Christine's news mentioned   (probably no one, right?)....

      We watched hyacinths take over one of our nearby reservoirs in Blantyre.

      Manual removal is pretty easy.  It would take lots of man power but Malawi
      should have that, if it has money available to pay people.  It may not cure
      the problem entirely but once the major push to get this take-over by the
      plant is under control a smaller, consistent effort should be able to
      contain the continuing problem.
