Provided is cement burning apparatus 1 comprising a dryerfor drying high-water-content organic waste of which water content is 40 mass percent or more, in which combustion gas extracted from outlet portions or ceiling, portions of preheater cyclonesA toD of a cement kilnis fed to the dryer. As the dryer, a grinding-type flash dryer, which directly contacts the combustion gas G with the high-water-content organic waste W while grinding it, can be used. In addition, the apparatusfurther comprises a coarse powder separatorfor separating coarse powder from the combustion gas extracted from the range described above, and the combustion gas G from which dust is separated by the coarse powder separatorcan be fed to the dryer, and the dust concentration of the gas fed to the dryermay be adjusted to 0.05kg/Nmor more and 0.35kg/Nmor less.

Cement burning apparatus and method of drying high-water-content organic waste

A cement kiln from which its brick lining has been removed, or a rotary dryer for cement production is used as a fermentation treatment apparatusfor converting waste matter into compost. The waste matter to be subjected to the fermentation treatment includes city waste contained in garbage bags, and its fermentation treatment is carried out by introducing the waste matter directly into the aforesaid cement kiln or the aforesaid rotary dryer for cement production without tearing the aforesaid garbage bags.

Method and apparatus for fermentation

A method of decontaminating a medium containing polychlorinated biphenyls (PCBs) or dioxins is disclosed. The contaminated medium is brought into contact with hairy roots derived through introduction of an Ri plasmid from,into a plant capable of absorbing, or absorbing and decomposing PCBs or dioxins, or is brought into contact with regenerated plantlets derived from the hairy roots, to thereby cause the hairy roots or regenerated plantlets to absorb, or absorb and decompose PCBs or dioxins.
