Non-woven cover for containing and abating odiferous organic emanations

An odiferous organic compounds containment system comprising:

• a) decaying organic material;
• b) a odiferous organic compounds cover oriented such that at least a portion of the decaying organic material is covered by the odiferous organic compounds cover, wherein the odiferous organic compounds cover has an inner surface and an outer surface and comprises:
• i) a thermoplastic non-woven layer having a first side and a second side and comprising thermoplastic fibers, wherein the first side of the non-woven layer forms the inner surface of the cover, and wherein the first side of the non-woven layer has a contact angle with water greater than about 70° and is non-wicking, non-wicking being defined as having a water vapor transmission of less than 1000 g/m2/24 hours as measured by ASTM E-96 standard, and wherein the thermoplastic fibers have a diameter;
• ii) a UV barrier layer on the second side of the non-woven layer comprising a UV blocking polymer, wherein the UV barrier layer has a layer thickness, wherein the UV blocking polymer blocks at least 50% of UV(C) energy, wherein the UV barrier layer has a thickness of between one to three times the diameter of the thermoplastic fibers of the non-woven layer, and wherein the UV barrier layer comprises discontinuities forming microchannels through the layer thickness;
• and,
• iii) an odor mitigation layer on the UV barrier layer on the side of the barrier layer opposite the non-woven layer, wherein the odor mitigation layer has a layer thickness, wherein the odor mitigation layer comprises a UV translucent polymer wherein the UV translucent polymer transmits at least about 60% of UV(C) energy and anatase titanium dioxide, wherein the odor mitigation layer comprises discontinuities forming microchannels through the layer thickness, and wherein the odor mitigation layer forms the outer surface of the cover.
