Abstract: Economic criteria have prevailed in studies on integration of renewable energies. Tons of dangerous emissions are emitted by a biomass fuel, causing negative impacts over atmosphere and health. Current research proposes Pinch Analysis of solar thermal energy and the joint use of biomass (sugarcane bagasse) to produce heat and power in a Caribbean sugar mill; measuring emissions like: carbon oxide C O , carbon dioxide C O 2 , dinitrogen monoxide N 2 O , nitrogen oxides N O x , sulfur oxides S O x , non-methane volatile organic compounds NMVOC, methane C H 4 , and particulate matters, to have a global and clear view of the impacts of biomass as a renewable fuel. Variables like kWh cost, the installation and device area of renewable energy, and greenhouse gas emissions, are analysed to assess the effect on the integration final design, the target of which is to control the use of biomass. It is possible to produce an economically competitive integration design of solar system L C O E t h s o l a r = 0.0636 USD/kWh, L C O E e l e = 0.1392 USD/kWh), zero greenhouse gases emissions ( Δ T m i n r e w = 7 ° C ), and deletion of 378,711.53 t/year of C O 2 and 9567.56 t/year of solid particles. There are many possibilities that can implemented; in one of them, bagasse burning is reduced by 30% and the solar collector network for required power production is reduced by 68%.
