                                   Compost as Cure-Ail
    Compost as soil amendment. Compost as pollution filter. Compost as disease control.  And
    now most recently, compost as erosion control. Is there anything compost can't do? Managers
    and employees at Filtrexx International, LLC are pleased that the use of compost's newest
    application has spread. The company's full-time business is using compost to prevent erosion
    along highways, at construction sites, and other transportation and building locations.

    There are many advantages of using compost-based tools over conventional erosion control
    methods. In the first place, compost is simply more effective at controlling erosion than many
    other technologies. "Compost, when properly installed in long filter berms, has been shown to
    work better than silt fence in keeping both suspended and settleable solids out of water sources
    moving on the surface," says Rod Tyler, manager of Filtrexx.

    Not only does compost do the job better than other materials, but it also has a variety of positive
    environmental qualities: it is natural, renewable, locally made, bio-based, and easily vegetated.
    The compost that Filtrexx uses comes from  a number of different feedstocks, including yard
    trimmings, biosolids, and food scraps, reports Tyler, and complies with the standards set forth
    by the  U.S. Composting Council.

    Compost also has benefits involving time and money. Generally, the installation time for
    compost-based tools is less than traditional tools. Filter socks, for instance, can be filled off site,
    saving time  in the field. Although the upfront cost might be greater than traditional tools, the
    overall price of compost-based tools can be less. Both compost filter berms and filter socks can
    be easily vegetated and incorporated into the landscape when the job is completed, so removal
    and disposal is unnecessary.

    Unfortunately, most people  are generally unaware of compost-based tools and often look at  price
    over performance but Tyler hopes that Filtrexx's erosion control tool  box will become as
    accepted as many other common best management practices currently in use. He envisions  a
    very steep growth curve for erosion control with compost over the next 5 to 10 years.
