The following is a list of IGA/P's that I am currently working on or will implement in the future.
1) Production of paraffin from heating and condensing plastics
2) Solar-ovens: keywords to search for "Kenya solar cookers" is by far the best results with google search.
3) Recycling paper: check out cardsfromafrica.com, and organization based out of Rwanda which produces greeting cards to be sold online. Atleast this is a great fine-arts project at minimum.
4) Paper jewelry: A trend for many fund raisers in schools and community groups is making paper jewelry, this can be done almost with no cost. To find more information, try researching "triangle paper beads, and paper beads", the process takes some refinement but I have found local groups that are willing to give much needed insight into the production of the jewelry.
I hope this may provide some grounds for the reader to kick-off a great IGA/P. GL.!
