NOVELTY - Odoriferous organic compound cover has inner surface (111) and outer surface (133), comprises: thermoplastic non-woven layer (110) having first side and second side and comprising thermoplastic fibers where the first side of the non-woven layer forms the inner side of the compost cover and is non-wicking; a UV barrier layer (120) on the second side of the non-woven layer comprising a UV blocking polymer, an odor mitigation layer (130) on the UV barrier layer comprising a UV translucent polymer and the odor mitigation layer forms the outer surface of the compost cover.    USE - The odoriferous organic compound cover is useful: in the odoriferous organic compounds containment system cover, to block, adsorb, and break down a portion of the odors emanating from the composting organic and inorganic waste; and to cover decaying organic materials (all claimed).    ADVANTAGE - The odiferous organic compounds cover can control odorous fumes and pathogens developed during decomposition of the waste, provides appropriate gaseous exchange and water vapor transmission to provide an optimal aerobic environment and provide operational reliability, product quality, minimum investment and operating cost.    DETAILED DESCRIPTION - Odoriferous organic compound cover have an inner surface (111) and an outer surface (133), comprises: a thermoplastic non-woven layer (110) having a first side and a second side and comprising thermoplastic fibers, where the first side of the non-woven layer forms the inner side of the compost cover and has a contact angle with water greater than 70 degrees and is non-wicking having a water vapor transmission of less than 1000 g/m2/24 hours as measured by ASTM E-96 standard; a UV barrier layer (120) on the second side of the non-woven layer comprising a UV blocking polymer which blocks at least 50% of UV(C) energy, the UV barrier layer has a thickness of 1-3 times the diameter of the thermoplastic fibers of the non-woven layer and comprises discontinuities forming microchannels though the layer thickness; and an odor mitigation layer (130) on the UV barrier layer on the side of the barrier layer opposite the non-woven layer, where the odor mitigation layer comprises a UV translucent polymer which transmits at least 60% of UV(C) energy and anatase titanium dioxide and comprises discontinuities forming microchannels though the layer thickness and where the odor mitigation layer forms the outer surface of the compost cover. An INDEPENDENT CLAIM is also included for odiferous organic compounds containment system comprising: (a) decaying organic material; and (b) the odiferous organic compounds cover oriented such that at least a portion of the decaying organic material is covered by the odiferous organic compounds cover    DESCRIPTION OF DRAWING(S) - The figure illustrates a cross-section representation of the odoriferous organic compounds cover.
