One of the main inequalities in Brazil is related to electricity access and distribution. On average, 99.7% of the population have access to some type of energy, varying from 99.1% to 99.9% among the Brazilian states. However, 600 thousand Brazilians still have no access to electricity. This paper aims to relate the distribution of electricity to s...
Construction and demolition (C&D) waste comes from engineering activities.

In homes that have instantaneous gas heaters to heat water, cold water is wasted in the first seconds of using hot water fixtures. This waste is caused due to the large lengths of piping between the hot water fixtures and the heater that feeds them. The water in such pipes suffers thermal losses over time. When turning on the fixtures, this drinkin...
