Abstract

The accelerated demographic growth, the increase of the purchasing power of the population and the cities development, contribute to the building sector being responsible for a big part of impacts caused in the environment. In addition to consuming non-renewable energy and natural resources, it alters the landscape and generates a large volume of waste, a reflection of inefficient management. The objective of the work is to elaborate a civil construction waste management database, targeted do entrepreneurs and environmental consultants, to the Hotel Chain from Gramado/RS. The data were collected in four different hotel enterprises, which are in construction, located in Gramado/RS, through the filling of a check list. The information about the waste have been detected by the Cargo Manifest of Waste provided by the Companies, and so being posted in an Excel spreadsheet. As results, the generation quantitative data (total of 760.1718 t and 747.3 m³) shows that the waste from type B was the most expressive (726.2648 t e 460.4 m³), corresponding to 95.53% and 61.60% of the waste generation, respectively and classified (11 of 23 kinds). Related to the storage and packaging, the waste from type A are placed in the soil, the waste from type B and C in stalls, bags or boxes that are covered and identified by color and type, and the ones from type D, according to technical standards. The results provide subsidies to a sustainable management of the waste to the entrepreneurs and environmental managers with data close to reality for the preparation of Waste Management Plans. The efficient management depends on right activities in the building site, looking not only for profits with the waste, but also the reduction of costs of the destination ant treatment, trough the reuse and recycling, projecting always the social, environmental and economic axis of sustainability.
