Household waste solid

Septic Tank Untreated liquid household wastes (sewage) will quickly clog your absorption field if not properly treated. The septic tank is a holding tank in which this treatment can take place. When sewage enters the septic tank, the heavy solids settle to the bottom of the tank the lighter solids, fats and greases partially decompose and rise to the surface and form a layer of scum. The solids that have settled to the bottom are attacked by bacteria and form sludge. 

WAS Waste activated sludge, mg/L. The excess growth of microorganisms which must be removed from the process to keep the biological system in balance. Wastewater The used water and solids from a community that flow to a treatment plant. Storm water, surface water, and groundwater infiltration also may be included in the wastewater that enters a wastewater treatment plant. The term "sewage" usually refers to household wastes, but this word is being replaced by the term "wastewater". 

Municipal solid waste incinerators (MSWIs) are a robust treatment method for very different mixed waste types of different origin. The typical MSWI handles waste of a calorific value between 9 and 13 MJ/kg. They are the key technology for the treatment of integral household waste in countries such as Denmark, Sweden, the Netherlands and Germany. Some 7% of this integral household waste consists of plastics. Treatment of... 

The feasibility is discussed of producing energy from household waste. Plastics represent only 7% of all municipal solid waste, but this represents 30% of the... 

Dechlorination of mixed plastics from household waste, after separation from municipal solid waste, and co-injection with coal into a blast furnace for pig iron production. The aim is to replace pulverised coal in this process (www.vinyl2010.org). 

A great proportion of plastics end its lifetime as a part of the overall solid waste stream where they represent roughly 10 wt%. The typical distribution of plastics in household wastes is shown in Figure 3.1 [3]. The main components are polyolefins low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE) and polypropylene (PP), accounting for about 67% of the total amount of plastic wastes. Other important components in plastic wastes are polystyrene (PS), poly (vinyl chloride) (PVC) and poly (ethylene terephthalate) (PET). 

Prior to the erection of the pilot plant at Velsen, a small test reactor consuming up to 60 kg/h of solid waste was installed at Neunkirchen next to an incinerator, which was to prove feasibility of solid waste gasification. During 2 1/2 years of test runs amounting to about 10 000 hours, all kinds of materials were charged to this reactor. For instance rubber, plastics, wood, used lubricating oil mixed with household waste. A reasonable gas composition could be maintained for any length of time ...

Parera et al. (2004) were the first to compare the extraction efficiencies of SCCPs from sediment using MAE and Soxhlet and showed extraction recoveries to be comparable [29]. Using ASE, Tomy et al. (1999) found recoveries of MCCPs in the range of 79-108% in spiked sodium sulfate (a surrogate for solid samples) [16]. Marvin et al. (2003) also used ASE for extraction of SCCPs in sediment surrogate recoveries of greater than 75% were reported [20]. Nilsson et al. (2001) also applied ASE to the extraction of household waste and found greater than 90% recoveries of MCCPs [30]. 

All waste batteries are considered RCRA solid waste except those that are returned to the manufacturer for regeneration, reused as an ingredient without reclamation, reused as a substitute, or returned as raw material. The largest percentage of disposed batteries are part of household waste and therefore exempt from regulation. The remaining waste batteries must be determined by the...

Criteria for municipal solid waste landfills, as promulgated in 40 CFR 258, limits bulk or non-containerized liquid waste placed in a sanitaty landfill to (a) household waste (other than septic... 

The presence of a gasification unit opens up possibilities for the gasification of all kinds of organic wastes, such as solid waste, plastics, sludge, rubber wood and household waste (Schwarze Pumpe, 2002). 

Disposable diapers are the third largest single consumer item in landfills, and represent about 4% of solid waste. In a house with a child in diapers, disposables make up 50% of household waste. Disposable diapers generate 60 times more solid waste and use 20 times more raw materials, like crude oil and wood pulp. The manufacture and use of disposable diapers amount to 2.3 times more water wasted than cloth. Over 300 pounds of wood, 50 pounds of petroleum feedstocks, and 20 pounds of chlorine are used to produce disposable diapers for one baby each year. Disposable diapers contain traces of dioxin, an extremely toxic by-product of the paper-bleaching process. It is carcinogenic chemical, the most toxic of all cancer-linked chemicals.

U.S. Environmental Protection Agency (ERA) The Municipal Solid Waste Factbook http // www.epa.gov/epawaste/index.htm (accessed November 3, 2010). An electronic reference manual containing information about U.S. household waste management practices including the complete text of EPA s regulations for municipal solid waste landfills. 

North of the assessed drill in the former stone quarry there is an illegal dump of solid household waste. The composition of waste dump as well as the migration of possible contamination are not known and more detailed information is not available. However, the extended analysis of water in the drill did not detect the leak of contaminants from the illegal dump into the hydrogeological col-... 

The major (nonhazardous) solid waste provision in RCRA is the prohibition of open dumps. This prohibition is implemented by the states, using EPA criteria to determine which facilities qualify as sanitary landfills and may remain open. EPA was required to revise the sanitary landfill criteria for facilities that receive small quantities of generator hazardous waste or hazardous household waste. In general, the new criteria require liners, leachate collection, groundwater monitoring, and corrective action at municipal landfills. 

Solid adhesive waste from the home such as hardened paper or wood glue is usually disposed of with the rest of the household waste. 

In determining the degree of hazard of a waste, it is reo nized that a listed hazardous waste is generally of greater concern than a liquid or soUd industrial waste. These are in turn of greater concern than other solid wastes. Municipal and organic wastes are considered medium concern contaminants due to their putrescible nature (production of methane and other landfill gases). Household wastes may contain hazardous materials (e.g., batteries, medical wastes, paints, etc). 

Mixed plastics waste appears to be well suited for use in energy recovery, either as a co-eombustion fuel in a power plant designed for solid fuels, or as the sole fuel in speeially designed plants. This paper reports test results on the co-combustion of mixed household plasties with eoal. The tests were performed in a bubbling fluidised bed low-pressure steam boiler. The results show that both inorganic and organic total specific emissions were lower for mixed household plasties than for coal. Tabulated data are presented. 3 refs.
