Off-site disposal of regulated medical wastes remains a viable option for smaller hospitals (those with less than 150 beds). However, some preliminary on-site processing, such as compaction or hydropulping, may be necessary prior to sending the wastes off-site. Compaction reduces the total volume of solid wastes, often reducing transportation and disposal costs, but does not change the hazardous characteristics of the waste. However, compaction may not be economical if transportation and disposal costs are based on weight rather than volume. Hydropulping involves grinding the waste in the presence of an oxidizing fluid, such as hypochlorite solution. One advantage of hydropulping is that waste can be rendered innocuous and reduced in size within the same system. Disadvantages are the added operating burden, difficulty of controlling fugitive emission, and the difficulty of conducting microbiological tests to determine whether all organic matters and infectious organisms from the waste have been destroyed. On-site disposal is a feasible alternative for hospitals generating two tons per day or more total of solid waste. Common treatment techniques include steam sterilization and incineration. Although other options are available, incineration is currently the preferred method for on-site treatment of hospital waste. A properly designed, maintained, and operated incinerator achieves a relatively high level of organism destruction.
Incineration reduces the weight and volume of the waste as much as 95 percent and is especially appropriate for pathological wastes.
On the basis of above passage please answer the following question
One disadvantage of the compaction method of waste disposal is that it
