In situations where windrows could become saturated from excess rainfall and/or snowmelt which creates anaerobic conditions, ComposTex prevents those conditions and the unpleasant odors associated with them.
While we are not aware of research that would explain how ComposTex can reduce the “release” of odors even though the fabric is permeable to gases, we do have a few customers successfully using ComposTex for that purpose. Two theories regarding the ability of ComposTex to prevent the release of unpleasant odors are:
- ComposTex’s tightly bound matrix of polypropylene fibers acts as a filtration media which captures odor molecules, and/or the water vapor containing these molecules.
- By protecting the surface of the windrows from the wind, ComposTex is also preventing dust and/or odors from being transported away from the windrows.
- Is there a certain side of the fabric that should be facing up or down?
- While there’s both a shiny and a rough (ie. fibrous) side of ComposTex, there’s no measurable difference in terms of water shedding between these two different sides. However, putting the shiny side down will reduce the amount of compost ingredients that could stick to rough side. and also provides some additional friction (grab) between the cover and the anchors used to hold the cover down. Having the rough side facing up also provides some additional friction between the cover and whatever anchors or weights that are being used to secure it from the wind.
