This invention provides granular materials for environmental improvement that, after being introduced into a body of water, initially float to promote the attachment and dispersal of microorganisms, and then naturally sink to improve the bottom sediment. [Solution] This granular material is formed by mixing a base material containing iron powder and carbon powder with a lightweight porous material derived from plants and then press-molding it. The granular material has a fine void structure inside, and initially floats on the water surface or near the surface due to the buoyancy of the void structure and the lightweight porous material derived from plants. After a certain period of time, as water is absorbed due to the stagnation of the water and the iron powder oxidizes, the specific gravity increases and the material sinks. Without using any special power or equipment, it can gradually achieve both "diffusion and microbial attachment in the surface layer" and "improvement of water and sediment quality in the bottom layer" simply by being added. Furthermore, by using recycled materials such as used hand warmers as the base material, it is possible to provide a resource-recycling material with a low environmental impact.
