Abstract | The present invention provides: a composition for treating debris in order to separate earth and sand from the debris that contains the earth and sand adhered thereto, the composition containing 0.1 to 10 mass parts of a polymer flocculant relative to 100 mass parts of gypsum, in which the gypsum has a BSA specific surface area of 15000 cm2/g or less, and the polymer flocculant takes a form of a powder containing 95% or more of particles having a particle size of 200 μm or less; and a method for treating debris including a treatment step of adding 10 to 100 kg of the gypsum and 0.01 to 10 kg of the polymer flocculant to 1 m3 of the debris containing earth and sand adhered thereto, and then kneading the resultant mixture, and a separation step of separating a kneaded product obtained in the treatment step into the debris and the earth and sand adhered to the debris. According to the present invention, it is made possible to, easily, simply, and efficiently, separate earth and sand from debris that contains the earth and sand agglutinated thereto without exerting a bad influence on the environment, such separation being a prerequisite for the disposal of an enormous amount of debris produced through the mingling of the substances destroyed and torn by strong force of tsunami or the like with the earth and sand carried by tsunami or the like. |
