Abstract:
Brazil is a major sugarcane (Saccharum officinarum L.) producer and its production more than doubled over the last decades to meet global bioenergy demands for reducing crude oil dependency and mitigating climate change. With the progressive shift from a burned to a non-burned harvest system, most of the straw presently retained on the soil surface has become economically viable feedstock for bioenergy production. Large-scale bioenergy demand has triggered new approaches to straw management in Brazilian sugarcane fields in fact, straw is a promising feedstock for bioelectricity and cellulosic ethanol in Brazil since has become available in large quantities in the field. Straw can be used as fuel for cogeneration systems of sugarcane mills to increase surplus electricity for commercialization. However, the exploitation of straw potential is still limited due to some challenges related to its agricultural harvesting. In this work, two innovative solution for straw recovery are proposed to increase the quality of the biomass reducing the ash content and simplifying the harvesting value chain. The first possibility evaluated the change of the windrowing process technique, from the traditional one to the belt windrower. The second possibility studied was the baling of the straw biomass directly from the harvesting machine, directing one fan of the cleaning system into the baler that follows the harvesting machine. The two harvesting systems proposed tackle the problem providing a solution at the present bottlenecks. However, further studies will be needed to provide scientific evidence of the solutions proposed by acquiring experimental data during straw harvesting field test
