Knowing what large scale vermicomposting is would help you decide on which path you should go. This new venture would require not just a part of your time (unlike with small scale worm composting) but it would ask for much attention from you.
Commercial vermicomposting systems have been established to make the process faster and easier. If you are used to home based composting which requires only of a worm bin, shredded newspapers and Red Wiggler worms, this time, you need machineries that will help you achieve your goals. Basically, to determine what commercial vermicomposting is, you will have the word "business".
There are two types of systems in this area. First is the windrow system and the other one if flow-through bed system. Both are effective in terms of getting as much Red Wiggler worms as possible. The only deciding factor on your part is your available fund and other resources.
For the windrow system, a mechanical harvester is a must so you can harvest the end product of worm composting. You can expect around 1.5 tons of compost everyday but you are to have a big building to accommodate the system.
Flow-through bed system on the other hand gives you the ease in harvesting because the need to separate the Red Wiggler worms from the vermicompost has been eradicated. It is also good in the sense that the nutrients in the byproduct are not harmed or reduced as the worms go through the process. You can have as much as 700 lbs of wastes per week depending on the size of your system.
These two systems determine what large scale vermicomposting is. They come in different sizes and prices but they are surely effective when you want worm composting to be your business.
