Textraw consists of:
65 %+ polypropylene, a photodegradable polymer;
25 %+ of calcium carbonate;
<1 % heavy-metal-free inorganic pigment
< .5% HALS (light stabilizer);
Photodegradation consists of a gradual crazing and powdering of surface material as the molecular structure of the polymer breaks down under the influence of ultraviolet (UV) radiation. The powder consists of its basic molecular elements, which are
• Carbon Dioxide
• Iron Oxide
• Calcium Carbonate
• Nitrogen Oxide
• Ammonium Compounds
These elements occur naturally in the environment, and are non-toxic.
The environmental considerations, then, depend primarily on proper use. We do not recommend that Textraw be used in areas subject to flooding, wash-out, or heavy water run-off, such as under down-spouts.
On steep slopes, a tackifying agent such as Stay Put should be applied annually. And wherever possible, border edges should be installed between traffic areas and Textraw installations. Because of its negligible profile, Textraw is very wind-resistant. An application of Stay Put, however, will assist in either blowing or vacuuming leaves from the surface.
When Textraw has reached the end of its lifecycle, clean material may be recycled. Alternatively, Textraw may be incinerated.
These considerations should be weighed against similar factors regarding alternative mulches: The energy cost of semi-annual harvesting and distribution in the case of pine needles. In addition to energy, the loss of habitat associated with the harvesting of cypress wetlands. The heavy-metal contamination of shredded rubber, or arsenic leaching to groundwater from shredded pallets.
