Extract: There are two problems, bioaerosols and smelly organic chemicals. Open windrow composters are prolific sources of airborne bioaerosols, mould spores. They occur naturally and, at low concentrations at least, for most of us our immune systems cope well with them. However, for the unfortunate few, those with allergies or immune systems impaired by cancer or transplant therapies, these spores can cause serious illnesses such as Farmer’s Lung or aspergillosis.
