  • Water- and oil-absorbent medium comprising milled sphagnum, sphagnum moss, and/or sphagnum peat
    Patent number: 6890651
    Abstract: Sphagnum, sphagnum moss, and/or sphagnum peat is milled to create a multitude of sphagnum, sphagnum moss, and/or sphagnum peat particles substantially all of which have a size less than about 850 microns. Particles of milled sphagnum moss have been shown to retain excellent water and oil absorption capabilities until particle sizes become smaller than 180 microns.

  • Medium and method for binding chlorine gas
    Patent number: 6555007
    Abstract: A fiber-based medium and method for binding chlorine gas utilizes sphagnum, a fibrous wetlands plant that is commercially available in dried form as sphagnum moss and sphagnum peat moss. It has been discovered that sphagnum moss is capable of binding up to 10% of its dry weight in chlorine gas, making it significantly more effective than activated carbon as a binding medium for chlorine gas. Sphagnum, sphagnum moss, and sphagnum peat moss each possesses the ability to bind chlorine gas.
