Household refuse, often considered merely waste for disposal, is being considered as fuel for utility boilers [1] , for chemical feedstock for pyrol­ ysis to produce fuel gas and oil [2,3], and as media for anaerobic digestion by bacteria to produce methane [4]. Previous chemical analyses of this por­ tion of municipal solid waste were directed only at incineration [5] . The organic portion of ...

As the generation of industrial wastes increases, waste treatment is steadily becoming a serious economic and environmental issue. Existing waste has mainly been treated by landfilling after incineration. A shortage of landfill sites necessitates waste management alternatives other than traditional incineration and landfill. This paper focuses on a cost-benefit analysis that evaluates the econo...

Modem municipal waste combustors (MWC's) process approximately 100 million tons of refuse each year in the United States, Europe and Japan, producing 30 million tons of ash. The incineration process has the effect of concentrating the toxic heavy metals normally present in municipal refuse. As a result, the ash may require treatment to reduce the quantity or the mobility of heavy metals within ...

Mr. Nowak's paper finally puts European incinera­ tor practice in its proper perspective. It is interest­ ing to note that incineration is selected for the dis­ posal of refuse for the same reasons in his country that are usually used in our country. Perhaps the decision to generate steam from refuse in this country will follow thei r decision process. Mr. Nowak has pointed out that burning ref...

Solid waste management is challenging in Phnom Penh city, Capital of Cambodia. The only one formal treatment taken is the final disposal of mixed waste into an open dumpsite. The current study analyses the physical and chemical characteristics of municipal solid waste disposed of in the dumpsite to assess their suitable handling methods. The current study found that the major compositions of wa...
