With the increase of Brazilian economic growth and, consequently, the level of construction activity, the generation of residues from this sector is an important problem to be solved. Alternatives to recycle these residues, often in the composition of new materials, and developing models and management tools have been studied in several papers presented to the technical means in order to mitigate the effects caused by the impact of construction on the environment. However, the absence of public policies that consider the generation, handling and disposal of these wastes as a real problem, are still the biggest obstacle in the adoption of sustainable practices. This paper presents the general aspects of the management of waste generated by construction operations and demolition works to reform the Palestra Italia Arena (Allianz Parque) in the city of São Paulo by means of activities of recycling and reuse of these materials on the construction site of the works. The management of the demolition wastes produced in the construction work allowed significant economic gains, reducing transportation costs and acquisition of natural raw materials. The great part of the total amount of waste produced could be characterized as Class A. [ABSTRACT FROM AUTHOR]

Industrial sand is used as raw materials in glass industries, foundry, ceramic, chemical, paint, plastics and many others. The Brazilian largest reserves are located in the states of Sao Paulo and Minas Gerais. The largest deposits and operating mines in Sao Paulo State are located in the Analandia and Descalvado municipalities. The aim of this paper is to characterize the segment of industrial sand countrywide emphasizing the spatial distribution of reserves, the level of production and production facilities, and both the technological and environmental challenges related to sand mining and processing. It also includes estimates for the industrial sand production from 2012 to 2030 and compares to the existing reserves. The desire to know the main challenges and prospects of industrial sand production in Brazil has guided the research presented in this article [ABSTRACT FROM AUTHOR]
