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!
Greywater, sometimes also spelled as graywater, grey water or gray water, is all of the effluent water from a household, such as water discharged from lavatories (bathroom sinks), bathtubs, showers, clothes washers, and laundry trays. Greywater is not wastewater from a sink used for food preparation, or water closet (toilet) wastewater.
The water leaving our homes carries nutrients and value. It may also contain pathogens, and/or harsh chemicals and care should be taken with it. However, it is not a great risk compared to blackwater (sewage).
Redirecting the water we use for tasks such as showering allows us to reclaim some of that value to grow plants and recharge the water table. It may be necessary to choose our soaps and detergents more carefully, if we use the greywater for watering and fertilizing plants.
