The invention belongs to the field of environment protection and relates to porous material prepared from solid wastes. The porous material is prepared from, by weight, 50-97% of solid waste parent material, 1-20% of a forming agent, 1-15% of a foaming agent and 1-15% of fluxing agent. By the arrangement, shortcomings that the porous material prepared from existing solid wastes require clay consumption, and the porous material is difficult to control, long in sintering time, high in energy consumption and severe in requirement of process control are overcome; the porous material prepared fromthe solid wastes is widely applicable and adjustable in particle size and shape, volume density, porosity size and percentage of close area of the porosity can be adjusted in a wide range, clay consumption is not needed, and short sintering time is achieved.
