| Number | Title | Issue Date |
| 6749660 | Solid-chemical composition and method of preparation for the anaerobic bioremediation of environmental contaminants coupled to denitrification This invention concerns the formulation and preparation of ammonium- and urea-free solid-chemical compositions for the anaerobic bioremediation of environmental contamination using the biological process of denitrification. The composition includes nitrate salts and... | 06/15/2004 |
| 6436164 | Process for granule production An agglomeration process by which granules are formed by the steps of: (a) injecting polymer having sufficient viscoelasticity; and (b) impacting particles on the polymer at the injection point. The present invention is advantageous because it overcomes the problems of ... | 08/20/2002 |
| 6372007 | Organic compost The present invention relates generally to organic compost used to treat soil. The compost serves as a source of plant nutrients, improves soil structure, encourages the growth of beneficial microorganisms and can be used as a vehicle in the formulation o... | 04/16/2002 |
| 5965117 | Water-bouyant particulate materials containing micronutrients for phytoplankton Water-buoyant compositions comprising a source of micronutrients for photosynthetic phytoplankton growth are useful for stimulating photosynthetic phytoplankton growth in ocean areas devoid of such growth when deployed on ocean surfaces as floating partic... | 10/12/1999 |
