1. Technical and economic assessment of trash recovery in the sugarcane bioenergy production system
Mechanized sugarcane (Saccharum spp.) harvest without burning has been increasingly adopted in Brazil, increasing trash availability on the field. This study aims at showing the importance of using an integrated framework tool to assess technical and economic impacts of integral harvesting and baling trash recovery strategies and different recovery rates as

2. Impact of sugarcane trash on fertilizer requirements for São Paulo, Brazil
The area under mechanized sugarcane (Saccharum spp.) harvesting is expanding in Brazil, increasing the return of trash to the soil. The main questions regarding this management are: (i) after adopting unburned mechanical harvesting, how long will it take to observe decreases in fertilizer requirements, (ii) what will be the magnitude of this decrease and, (i

3. Contribution of nitrogen from sugarcane harvest residues and urea for crop nutrition
Sugarcane (Saccharum spp.) harvested without burning provides a substantial amount of remains (trash) on soil profiles which can be decomposed and release nutrients contributing to reduce fertilizer needs. The contribution of nitrogen (N) from sugarcane plant residues and fertilizer in sugarcane nutrition was assessed. Plant cane treatments were micro plots

4. Assessment of sugarcane trash for agronomic and energy purposes in Brazil
Due to new possibilities for using sugarcane (Saccharum spp.) trash for electricity generation, and the production of 2nd generation ethanol and others chemicals, the interest for its recovery has increased. However, the question of how much trash can be removed from sugarcane field still needs to be clarified. This study evaluated the amount of dry matter,

5. Subsidies for training of landfill associated Municipalities in the Mountainous Region of Quilombos in Alagoas. / Subsídios para formação de Aterro Sanitário Consorciado em Municípios da Região Serrana dos Quilombos em Alagoas.
The Industrial Revolution has put in place some "dreams". The materials and equipment began to be produced quickly, through the employment of machinery, so different processes craft. The importance of this study is its contribution in the survey data for the municipal managers develops public policies, management of solid waste and its final destination, thr

6. Eficiência agronômica das adubações nitrogenadas de plantio e após o primeiro corte avaliada na primeira soca da cana-de-açúcar / Agronomic efficiency of nitrogen fertilization at planting and after the first harvest, evaluated during the first sugarcane ratoon cultivation
Renewable energy sources will gradually replace non-renewable sources due to economic sustainability reasons and to the rational use of natural resources. Consequently, this study aimed to investigate sugarcane nitrogen fertilization in detail, which may help the country to become a world model in the production and use of renewable biofuels. The current kno

7. Adensamento do palhiço da cana-de-açucar utilizando helicoides conicos / Compaction of sugar cane trash using helical cones
This thesis aimed to show that agricultural producers could widen their role as consumers of agricultural lime - in Brazil, 70% of farmable soil is considered to be acid and require liming - and that such consumption would contribute to its sustainability, providing gains in the economic, social and environmental spheres. In addition, the use of agricultural

8. Analysis of six recovery systems for sugarcane trash / Analise de sensibilidade de seis sistemas de recolhimento do palhiço da cana-de-açucar (Saccharum spp.)
A biomassa é uma fonte de energia renovável, disponível e alternativa. Quando a colheita é feita sem realização de queimada, a biomassa da cana-de-açúcar, na forma de palhiço, é uma das fontes de energia renovável com enorme potencial no Brasil. Todavia, o aproveitamento desses resíduos em larga escala é dificultado pelo alto custo de seu recolh
