The concept of avoiding disposal costs is a form of savings that can be used to justify investing in larger scale vermicomposting systems.  Oregon Soil Corporation's website states: “Our 300' High Technology Reactor is capable of handling 2000 tons of organic food waste per year. This results in an annual landfill cost savings of $70,000. At the same time constantly producing a valuable product that can be sold and utilized as valuable plant growth media or soil amendments.” See: http://oregonsoil.com/products.php
