This system is used to compost large amounts of yard and kitchen wastes in a short period of time. Composting is a natural biological process where bacteria, fungi and other organisms decompose organic materials such as leaves, grass clippings, and food wastes.
Compost can be made by five different methods: holding units, turning units, heaps, soil incorporation, and worm composting. Holding unitContainers or bins that hold yard and garden materials until composting is complete.
With a substantial input of labor, a large volume of yard waste can be composted in a relatively short time (3 weeks to 6 months). Worm compostingFood wastes can be digested by red worms (red wigglers) placed in a bin with shredded and moistened newspaper, corrugated cardboard, peatmoss or sawdust. Choose a 3-foot-square site for your holding unit and pound the four wooden or metal posts into the ground 3 feet apart, at the corners of the square. A wood and wire three-bin turning unit can be used to quickly compost large amounts of yard, garden and kitchen wastes. Fasten a 9-foot length of hardware cloth to the back side of the bin, with staples every 4 inches around the frame. To complete the bin, nail the 16-x-24-inch pieces of plywood onto the base and sides at each end. To reinforce the bin, stagger nails at least every 3 inches wherever plywood and 2 x 4s meet.


Attach the hinges to the inside of the back of the bin at each end (on the 2 x 4), and the corresponding undersides of the back edge of the lid frame, so that the lid stands upright when opened. The unfinished bin should last for at least five years; finishing the bin with varnish or polyurethane will protect the wood and prolong the life of the bin. It is a good idea to put wet bedding material into the bin outdoors and wait until all the water has drained out (one to two hours) before setting the bin up indoors.
Heap composting is similar to turning-unit and holding-unit composting except that it does not require a structure (Figure 6). Incorporating food wastes into the soil well below ground surface is the simplest method for composting non-fatty food wastes.
Figure 7Soil incorporation is a useful composting technique if you need to dispose of small amounts of food waste. The method of composting selected will depend on when finished compost is desired, the materials to be composted, and the space available for composting.
Generally, every pound of food waste to be composted per week will require 1 square foot of surface area.
Lightly file each wire along the cut edge to ensure safe handling when opening and closing the bin. Insert the horizontal slats, six per bin, between the dividers and into the vertical slots. Cut the 4-x-4-foot sheet of exterior plywood into one 3-x-3-foot piece on one of the three bins, and attach each to the back, top board with two hinges.


If the heap will be turned, vegetable and fruit scraps can be added (check with local authorities for ordinances that may be in effect for composting). While composting occurs naturally, the process can be accelerated and improved by human intervention. Using the carpenter's square, or measuring between opposing corners, make sure the bin is square. A wire-mesh bin made without posts is easy to lift and provides access to finished compost at the bottom of the pile while the compost at the top of the pile is still decomposing.
Excess moisture will drain off most materials when they are placed into the composting bin; however, peat moss may hold too much water. Every three to six months, move the compost to one side of the bin, and add new bedding to the empty half.
Using the carpenter's square or measuring between opposing corners, make sure the bin is square, and tighten all bolts securely.
Fasten a 9' long piece of hardware cloth securely to the back side of the bin with staples every 4" around the frame.
