Composting for large scale operations
By adding EM to a composting process you can expect the following benefits:
-
more uniform heat, and therefore more efficient composting
-
more complete breakdown of materials -shorter composting time
-
higher quality compost...more energy...higher growth index
How to use EM in composting
EM can improve both aerobic systems and anaerobic systems.
The Christchurch City Council is the best example of a large scale aerobic system (read report). They introduce EM into the initial shredding process, by adding it to the water 1:1000 dilution. This ensures that the green waste is innoculated right at the start of the composting process. They will apply further EM if required to control odours.
Large scale anaerobic compost (similar to making pit silage), is practised by an increasing number of Vineyards in Marlborough and Canterbury. They are converting thier grape marc into good quality compost and returning this to their soils in the vineyard. Good examples of 100 cubic metre plus composting are Seresin Estate, Marlborough and Sherwood Winery, Waipara (read report on compost comparision using EM).
EM-A is usually added to the compost at 3-4 litres per cubic metre, in addition some rock phosphate and elemental sulphur will enhance the breakdown.
