Getting Ready!


The progress on the new ASP composting floor continues and is nearing completion. Soon we’ll be loading it and composting. We were able to test the air flow last week and the results showed an air throughput exceeding the Green Mountain design specification by 30%.

Our demonstration ASP zones continue to do well, we’ve completed 51 batches since February. Air is mostly comprised of 78% nitrogen and 20.9% oxygen and the average internal oxygen reading of our test zones is 18.05%. We will have no problem maintaining the aerobic composting process with the increased air throughput of the new floor.

When we get the zones loaded and in process we will invite you for a visit.
