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!
Appropriate technology (AT) is technology that is designed with special consideration to the context of its use - including environmental, ethical, cultural, social, political, and economical aspects of the community it is intended for. With these goals in mind, AT proponents claim their methods require fewer resources, are easier to maintain, and have less of an impact on the environment compared to techniques from mainstream technology, which they contend is wasteful and environmentally polluting.
The term is usually used to describe simple technologies proponents consider suitable for use in developing nations or less developed rural areas of industrialized nations. This form of "appropriate technology" usually prefers labor-intensive solutions over capital-intensive ones, although labor-saving devices are also used where this does not mean high capital or maintenance cost. In practice, appropriate technology is often something described as using the simplest level of technology that can effectively achieve the intended purpose in a particular location. In industrialized nations, the term appropriate technology takes a different meaning, often referring to engineering that takes special consideration of its social and environmental ramifications.
