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's Vermicomposting Bin
. I am very excited to be posting directions for building your very own home vermiculture
bin! The methods employed will produce a bin appropriate for a household of 3-5 people and should last a number of years if constructed properly. There of course are many types of bin designs out there and I wanted the creative opportunity to design my own. In looking for ideas in a gardening magazine, I noticed a pentagon shaped planter for gardens whose shape I really liked. A pentagon is also practical because compost is less likely to get stuck in the corners as often happens in normal square shaped boxes, preventing the organic materials from cycling properly. I decided to make a two-part stackable bin so that using the finished compost would be easier. Once the compost is processed it is easy to take off the top section, dump the compost in the garden, and put it on top to be filled again. The partitioned design is also improves aeration to speed up the composting process. Aeration is also provided by the holes drilled in the sides of the bin. The bottom of each bin section is finished with wire mesh to keep the compost in place. The holes of the wire mesh are large enough to allow worms and microbes to enter the system and speed up decomposition. The top is simple plywood cut to size with a brass handle and L-brackets to keep the lid in place. The bin was lastly finished with natural organic linseed oil as a sealer for endurance in the elements and general durability. I hope you enjoy!
