There is a world concern about greenhouse gases (GHG) emission and it was established on the 21 th Climate Conference in Paris that the global temperature cannot increase above 2°C.Due to climate change concern, there is a growing demand for bioenergy to replace fossil fuels.However, the advantages of bioenergy decrease if it leads to deforestation and/or indirect land use change (ILUC).Considering that, new models for renewable energy production are needed to simultaneously decrease GHG emissions, use land more efficiently and replace large amounts of fossil fuel.Ethanol and livestock integration as happens in the United States (USA) might be a possible solution for a new model of production.Brazil, the second largest ethanol and beef cattle producer in the world, can modify the USA model of corn ethanol and cattle integration for its own circumstances.Brazil uses about 168 million hectares as extensive pasture and about 9 million hectares for sugarcane production.These two products are pillars of the country's economy.This work evaluates the techno-economic and environmental feasibility of sugarcane ethanol and cattle integration, thereby avoiding pasture displacement by sugarcane expansion and the ILUC.Cattle before finished in pasture land can be finished in feedlots fed with sugarcane ethanol by-products (in natura bagasse, hydrolyzed bagasse, molasses, wet yeast plus grains).Intensification of cattle production by integration with sugarcane releases pasture area to produce more sugarcane, without needing more land for cattle production.For this study, six different scenarios were assessed varying relation between sugarcane and cattle area from 0 to 1. System-wide simulations were performed using the Virtual Sugarcane Biorefinery (VSB) model developed by the Brazilian Bioethanol Science and Technology Laboratory (CTBE).Data for the models were obtained from literature and current actual cases of beef cattle/sugarcane integration.The calculated economic parameters are internal rate of return (IRR), net present value (NPV) and payback time (PT).GHG emissions were assessed via Life Cycle Assessment using ReCiPe Midpoint (H) method and the Climate Change impact category.As result, integration decreases overall GHG emissions compared to non-integrated systems and techno-economic feasibility is achieved considering revenues from rental of released pasture area and from carbon credit.
