is the site for collaborative solutions in sustainability
reduction and international development
through the use of sound principles
and appropriate technology
and the sharing of wisdom and project
information. It is a wiki
, a type of website which allows anyone to add, remove, or edit content. Registration is encouraged but not required for contributors.
Appropedia has been described as an "appropriate technology wiki," but it is much broader than that - it is a green wiki, and a wiki for all matters of international development and aid. But most importantly, Appropedia is an open site for stakeholders to come together to find, create and improve scalable and adaptable solutions. For more about our motivation, see Appropedia:Mission.

CCAT natural paint project
. The Campus Center for Appropriate Technology
(CCAT) at Humboldt State University
in Arcata, CaliforniaW
is completely remodeling the inside of their building. When all of the construction is finished the entire interior of the house will need to be painted. As an ENGR 305
project, Spring 2007, Andrea Lanctot
and Jill Anderson
have decided to make all the interior paints from scratch using safe natural ingredients.
The project has four main goals. The first is to research natural paint ingredients, recipes, and techniques. The second is to make several of the recipes and test the paints for color, durability, and texture. The third is to choose paints from the tests for the new CCAT house and apply them to the interior. The last goal is to test the final application with the test of time. See natural paint basics for background research on ingredients, types and advantages/disadvantages of natural paint.
