1. A modular system for composting organic waste materials comprising a plurality of self-contained modular containers including a first modular container and a plurality of second modular containers for holding predetermined amounts of said organic waste materials for substantially the entire composting period, said plurality of modular containers having a size such that a relatively uniform temperature profile may be maintained within each of said plurality of modular containers, said first modular container holding said predetermined amount of said organic waste material which has been composting for a first period of time and said plurality of second modular containers holding said predetermined amounts of said organic waste material which have been composting for a plurality of second periods of time, said plurality of second periods of time being progressively shorter than said first period of time, each of said first and said plurality of second modular containers including air inlet means and exhaust means whereby air may be circulated through said predetermined amounts of said organic waste materials in each of said first and said plurality of second modular containers, temperature measuring means for measuring the temperature in said first and said plurality of second modular containers, interconnection means for selectively interconnecting said first modular container with a selected one of said plurality of second modular containers based upon said measured temperature of said selected one of said second plurality of containers being less than said temperature of said first modular container by a predetermined temperature difference, and circulation means for circulating ambient air separately through said first and said selected one of said plurality of second modular containers and for alternatively circulating ambient air through said first modular container and circulating said air from said exhaust means of said first modular container to the air inlet means of said selected one of said plurality of second modular containers, so as to accelerate the composting of said organic waste material in said selected one of said plurality of second modular containers.
