Biological waste disposal

Wastes contaminated with aniline may be Hsted as RCRA Hazardous Waste, and if disposal is necessary, the waste disposal methods used must comply with U.S. federal, state, and local water poUution regulations. The aniline content of wastes containing high concentrations of aniline can be recovered by conventional distillation. Biological disposal of dilute aqueous aniline waste streams is feasible if the bacteria are acclimated to aniline. Aniline has a 5-day BOD of 1.89 g of oxygen per gram of aniline. 

Landfarming Landfarming is a waste-disposal method in which the biological, chemical, and physical processes that occur in the surface of the soil are used to treat biodegradable industrial wastes. Wastes to be treated are either apphed on top of the laud which has... 

The laboratory operator must make a careful examination of all wastes that will be generated and, from this, work up a waste disposal system. Some wastes may be compatible and could be disposed of together. Others could react and thus cause problems. Flammables must be given special attention. Certain biological wastes may be very hazardous even in small quantities. Special rules apply to radioactive materials, even in the small amounts used for investigative purposes. 

Fomites Some pathogens may be absorbed into clothing or bedding causing these items to become infectious and capable of transmitting the disease. Others may contain vectors (e.g., lice, ticks) that pose a transmission hazard. Deposit items in an appropriate biological waste container and send to a medical waste disposal facility. 

Fomites Clothing or bedding may become contaminated with spores. Deposit items in an appropriate biological waste container and send to a medical waste disposal facility.

Cresols may be disposed of by landfill, land applications, biological waste water treatment, or incineration. In an activated sludge system, cresols exhibit a 96% reduction of the chemical oxygen demand and a biodegradation rate of 55 mg of oxygen/g-hour. Cresols may be disposed of in a rotary kiln incinerator with a temperature range of 820-C-1600-C and a residence time of seconds. Cresols may also be disposed of in a fluidized bed incinerator with a temperature range of 450 C-980 C and a residence time of seconds (HSDB 1989). 

According to Alternative Biowaste Elimination Technologies, LTD (ABET), the WR technology is a novel process that nses alkaline hydrolysis to liquify or dispose of biological waste (animal tissue) from research and clinical facilities. 

The vendor claims the enzyme solution is produced through a biological process and is nonhazardous. Enzyme solution is reused until the end of the project, when it can be injected into a nonhazardous waste disposal well or processed through a wastewater treatment facility. All information is from the vendor and has not been independently verified.

Hazard Identification. The process of determining whether exposure to a particular substance at any dose can cause a response in a biological organism and, if so, the type(s) of response is called hazard identification. Hazard identification typically involves doses of a substance that are much higher than would actually be experienced in routine exposures of the public, including exposures resulting from waste disposal. Once the hazardous nature of a substance is determined, the results are documented and the hazard identification process need not be repeated for other applications. 

A positive result of TDF use in waste wood boilers is that facilities are able to bum sludge and waste wood more successfully, decreasing the likelihood of solid waste disposal problems. Results from a series of waste wood boiler performance tests using ASMS codes concluded that use of TDF supplementally in hog-fuel boilers enhances combustion of wood waste, and enables disposal of biological sludge in conjunction with wood waste without necessitating use of other fossil fuels such as coal.2 No applicable environmental limits were exceeded during these tests.2...
