An erosion, sediment and pollution control product comprises a rice hull filler material which has been heat treated sterilizing the rice hull filler material and increasing the pollutant affinity of the rice hull filler material; and a containment member containing the rice hull filler material and allowing fluid to flow through the containment member and the rice hull filler material. The containment member is a geotextile which may include cellulose based threads treated to be hydrophobic.

A compost filter sock assembly comprising a filter sock and compost filter anchor system comprising one of i) an interconnected series of compost filter sock anchors alternating on the downstream and upstream side of the filter sock, wherein the compost filter sock anchors are interconnected with strapping between adjacent compost filter sock anchors on opposed sides of the filter sock such that the strap traverses the filter sock; or ii) a downstream wooden stake having a fin coupled thereto that extends laterally on both sides of the wooden stake.

A bio-friendly water flow control system can include a portable structure adapted to contain organic waste material. The water flow control system can be configured for deployment outdoors to guide water flow to limit erosion. A portable structure of such a system can include a sheath that is configured to contain waste material within an interior of the sheath. The portable structure may be configured to allow a flow of water into the interior of the sheath. The portable structure may include a waste material that includes processed palm frond particles. The portable structure may be configured to absorb a weight of water at least 50% greater than a dry weight of the portable structure.

System consisting of a pierced box-type outer casing made of nets of natural and biodegradable materials which, positioned on eroded coastlines, allows the incident wave motion to pass through, though trapping the suspended and transported particles inside the box, favoring the replenishment of the coast. The outer box is filled with horizontal net sheets with holes of different dimensions, ie with the size of the holes in the sheets that decreases from top to bottom. The bottom is the lower part of the box, positioned on the shore line.

A compost filter netting comprises plastic netting formed in a tube having a diameter of 6-36 wherein the plastic netting includes netting openings of - and configured to be filled with compost to form a compost filter sock, wherein the linear length of the compost filter sock is not less than 93% of the linear length of the originally manufactured empty compost filter netting. A method of forming a compost filter sock using the compost filter netting and the compost filter sock made thereby is disclosed. The compost filter netting substantially eliminates the problem of miscalculation of shrink rate that is problematic for in field applications.

A Composite Filter Sock Assembly includes a Compost Filter Sock and Secondary Tubular Seam Filling Device configured to be wedged beneath the compost filter sock on an upstream water runoff side of the compost filter sock, whereby the compost filter sock provides a pinning pressure to the Secondary Tubular Seam Filling Device and wherein the compost filter sock has a nominal diameter of 2-12 times a diameter of a tubular element of the Secondary Tubular Seam Filling Device. The Tubular Element may be least partially filled with a swell-able material such as sphagnum peat moss and may include a fastening mechanism on an exterior surface configured to facilitate coupling to a mesh tube of a compost filter sock.

A system for stabilization of a shoreline includes a plurality of stakes and a flexible sheet switchable between an open configuration and a folded configuration. The sheet has a first edge and a second edge, and each edge includes a channel in which an anchoring rope runs through. An organic material is disposed in a body region of the flexible sheet when the sheet is in the folded configuration. The first edge and second edge are secured to the plurality of stakes by the anchoring ropes.

A fiber block system suitable for check dam applications is described that comprises a central section flanked by two shorter wing sections. Each section comprises a fiber block enclosed in a sleeve of mesh. The fiber block, mesh, and ties can be made of coir fibers.
