Definitions

  • the present invention relates to a substrate for carrying either waste mitigation agents or odor mitigation agents and more particularly to a substrate on which substances effective in the degradation, mitigation and dispersal of waste materials, such as oil degrading microorganisms or odor neutralizing compositions, can be carried, maintained and delivered to a waste site.
  • Waste handling and treatment is a rapidly growing field in which new, environmentally safe treatment means and methods are continually sought. Waste is found in a number of locations varying from oil spills on the high seas to toxic landfill dumps to human wastes.
  • landfill is a shorthand term for municipal garbage dumps, toxic waste dumps, oil field waste pits, as well as land contaminated by runoff from materials stored on the land.
  • One age old problem that arises in these waste areas is malodorous vapors arising from wastes.
  • a more recent problem commonly encountered in treating all wastes is the lack of a means for transmitting modern treatment agents to the waste site.
  • Such oil degrading microorganisms are generally anaerobic, and become ineffective upon exposure to oxygen in the air. It is therefore difficult to deliver such microorganisms to the location of the oil spill on the surface of the water without diminishing their effectiveness in the process. Similarly, in the degradation of landfills and chemically polluted soil, it is difficult to deliver agents that degrade such waste materials without diminishing their effectiveness in the delivery process.
  • Waste mitigation in landfills is further complicated by an inability to distribute waste treating microorganisms evenly throughout the landfill.
  • a waste mitigation agent is difficult to apply to a landfill where the agent is not visible to the naked eye and thorough mixing into the landfill is nearly impossible to obtain.
  • Applying a waste mitigation agent to a landfill evenly is easily accomplished when the waste mitigation agent is bound to an environmentally sound substrate.
  • the substrate may be visibly distributed evenly in the required amounts to the landfill to be treated.
  • the buoyancy of a carrier that is, its ability to serve as a flotation medium, can profoundly affect its ability to serve as a substrate in waste mitigation.
  • Effective substrates for waste mitigation substances for use in liquid environments must not only serve as carriers for such substances (e.g. , micro- organisms, chlorophyll and the like), but also exhibit controlled buoyancy such that an appropriate portion of the surface area containing the waste mitigation substance maintains an appropriate contact with the atmosphere and with the liquid.
  • odor neutralization it is desirable that the treated substrate project and maintain as much of the odor neutralizing compound as possible above the surface of the liquid in order that the compound can neutralize the odors in the vapor space of a waste receptacle.
  • the treated substrate should float so that organic wastes such as fecal waste and vomitus deposited into the waste receptacle become coated with the treated substrate upon deposit.
  • the treated substrate float lower, thus projecting and maintaining as much of the oil consuming anaerobic microorganisms as possible below the surface of the floating oil.
  • This floating posture ensures that the microorganisms are kept from exposure to the oxygen containing environment above the surface of the water which would kill the anaerobic microorganisms, while maintaining the anaerobic microorganisms within the floating oil.
  • aerobic microorganisms may be developed which will devour or modify oil spills.
  • the treatment method of the invention should be equally applicable to both aerobic and anaerobic microorganisms.
  • odors carried by the winds are objectionable to both the workers at the treatment facility and to those who live or travel in the area surrounding the facility.
  • Odor control at these facilities where aeration ponds and clarifier systems are used must be accomplished without reducing the capacity of the treatment system and without plugging the operating equipment.
  • the odor mitigating agent must be effectively delivered to the odoriferous waste itself.
  • bed pan contents as well as vomitus are a constant source of malodorous vapors with which both the patient and the workers must contend.
  • waste odors can create discomfort and detrimentally affect the performance of medical duties.
  • waste odors can create discomfort and embarrassment, thereby compounding the misery of illness.
  • odor control agents used in these circumstances must be compatible with the eventual municipal waste collection and treatment system.
  • waste products are normally deposited into receptacles, such as a toilet, which contain liquid, usually water, for carrying the waste to a sewer or septic system.
  • organic waste disposal devices include portable toilets, in-ground campsite toilets, marine toilets, as well as aircraft, train and motor vehicle toilets. All of these traditional organic waste collection systems present odor control considerations which must be addressed by means which will not cause difficulties in the ultimate waste treatment facility.
  • chlorophyll the green photosynthetic extract from plants
  • Several animal litter formulations employ chlorophyll and a variety of porous substrates.
  • Conventional animal litter substrates include clays, corncob grits, comminuted popcorn, and chopped paper.
  • the primary purpose of animal litter is to absorb and contain animal urinary and fecal waste. Once the odor defeating agent contained on the litter sinks beneath the surface of any liquid present, the odor controlling ability of the litter is defeated.
  • Conventional animal litter is therefore unsuitable for use in neutralizing odors in liquid containing waste receptacles, such as toilets, because the substrate rapidly absorbs water and sinks.
  • Cork is a particularly effective, environmentally safe substrate material for odor and waste mitigation purposes, and can be treated with such substances as oil consuming microorganisms, chlorophyll, dyes and fragrances.
  • Cork is the elastic, tough outer tissue of the cork oak. When cork is finely comminuted into particles, it exhibits the ability to become coated and the cells impregnated with a thin layer of chlorophyll, in the case of odor neutralizing compositions, and then retain the chlorophyll on the surface of the cork particles and in the hollows of the cork cells.
  • finely comminuted cork exhibits the ability to adsorb microorganisms including anaerobic bacteria, and then retain the microorganisms and maintain their effectiveness.
  • the cell structure of cork may be utilized such that microorganisms may be stored in the interstices of the cork particles.
  • a coating impervious to air can be applied to cover various sized dosages of the anaerobic bacteria-cork combination such that these oil-mitigating microorganisms can be delivered to the oil-spill area.
  • nutrients for microorganisms may also be applied to the cork and within the cells of the cork to allow storage of the bacteria-cork combination for substantial periods of time within this coating impervious to air.
  • Cork particles are especially suited for use as an odor or waste mitigation substrate as they exhibit sufficient buoyancy such that the amount of surface area projecting above or below the liquid can be selected and controlled depending upon the application. For example, in odor neutralization applications which require high flotation on the liquid, the cork particles should exhibit sufficient buoyancy such that the surface area of the cork particles which projects from the liquid contained in the waste receptacle is at least as great as the surface area which resides within the liquid. In treating floating waste, such as an oil spill, the treated substrate should float with a majority of the substrate below the fluid surface.

La flottabilité du substrat est telle que la superficie des particules du substrat sortant du liquide contenu dans le conteneur à déchets est au moins aussi grande que la superficie des particules restant dans le liquide. Dans un mode de réalisation préféré, le composé neutralisant les mauvaises odeurs est de la chlorophyle et le substrat est du liège. Le diamètre moyen des particules de liège est de préférence inférieur à un millimètre. La composition peut éventuellement comprendre un additif parfumant adsorbé sur les particules du substrat. Pour la dégradation de substances résiduaires, un microoroganisme est adsorbé sur un substrat particulaire. Dans le mode de réalisation préféré où la substance résiduaire est du pétrole, le microorganisme est une bactérie anaérobie et le substrat est du liège. Le diamètre moyen des particules de liège est de préférence inférieur à un millimètre.
