Iíve recently bought a property where they had been using wheelie bins to collect and compost humanure. It looks like the contents of the bins have not broken down and remain smelly sludge. Some of the bins are dated as far back as 2013! Iím assuming this is due to lack of proper aeration (and potentially material as they used sugar cane mulch) as there are no vent pipes or drainage inside the bins.
Is there a way to safely compost the contents? If I dumped them all out (while wearing a hazmat suit ;) ) and mixed with straw or wood shavings and left them alone for a couple of years would this remedy the issue? Thereís about 7 bins that need to be dealt with and Iím on 30 acres so I have enough room to cordon off a toxic waste area.
Any help and advice would be gratefully appreciated as Iím not entirely sure what to do with them. Thanks!
