SOLID WASTE MANAGEMENT IN SMALL MUNICIPALITIES: THE CASE HISTORY OF PIRAÍ (RJ), BRAZIL© IWWG International Waste Working Group (10/2007)

Municipal Solid Waste includes commercial and residential wastes generated in municipal or notified areas, in either solid or semi-solid form excluding industrial hazardous wastes, but including treated bio-medical wastes (MoEF, 2000).

The latter is an aquatic marine plant, often commonly termed seaweed, which grows on the seabed meadows in spring and summer, shedding its long linear leaves, having turned from their original green colour to brown, in the autumn. Tons of these leaves are washed up by the waves on the shoreline. The layers of this seaweed along the shore at times reach the height of two metres, often being mixed with relevant amounts of sand.
