• Abstract:

  The search for renewable energy

  sources in Brazil encouraged the cultivation and

  expansion of sugarcane cultivation. However,

  this expansion, on a largescale, reduced dependence on fossil fuels and caused several environmental problems. In industrial

  processing, to produce ethanol and / or sugar, there is production of by-products

  (waste) such as bagasse, ash, washing water, vinasse, etc., and the sewastes were

  improperly disposed of, polluting water resources and rendering areas agriculture. In

  this way, research has emerged to reduce the pollution caused the environment by

  these residues, through the creation freecycling and reutilization processes, mainly for

  vinasse that is produced with greater proportion. In view of this important issue, this

  review aimed to highlight the residues from the sugar-alcohol industry, as well as the

  losses and benefits that these cause to the soil-plant-atmosphere system and to the

  environment. An alternative to minimize the impacts is the reuse of these in several

  sectors with adequate management, such as energy generation through bagasse, crop

  fertigation with vinasse, implementation of dry-cleaning systems to reduce the amount

  of waste, etc. In this context, efficient management reduces environmental impacts and

  may allow greater productivity in the sector.
