Espacialização do banco de sementes de plantas daninhas sob diferentes manejos de cana-de-açúcar em Rio Brilhante, Mato Grosso do Sul

The State of Mato Grosso do Sul is in full growth of this sector, thus the concern about harvesting systems are being studied, and these systems may influence the weed community interference of weeds in the cane sugar. The integrated management tool attached to geostatistics is to avoid productivity losses due to weed interference. The objective of this work was to study the spatial variability of the seed bank of weeds depending on the system for collecting cane sugar (raw and burning). The experiment was conducted in the area of commercial cultivation of the plant ETH Bioenergy S/A Eldorado Unity. Soil samples were taken with auger layer from 0.00 to 0.40 m depth in both cropping systems. The experimental plot was composed by a mesh consisting of 50 points georeferenced with irregular distances. Soil samples were taken to the greenhouse for germination. The number of weed species was analyzed using descriptive statistics and geostatistical techniques. The seeds of B. pilosa, dicots, bitter grass, nutsedge, dayflower monocots and spatial dependence of the seed bank in the collection system with burning of cane sugar. For the system of harvest only the raw sedge species present spatial dependence of distribution in the seed bank. In the harvest green cane enable the mapping of these species through the kriging maps produced, spot applications of herbicides in integrated management of Cyperus rotundus.

Proposta de traçado de alcoolduto ligando a hidrovia Tietê Paraná à refinaria do planalto paulista com uso de avaliação multicritérios e geotecnologias

From the beginning of the century, with the advent of the flex fuel car, successor fluctuations in oil prices and the rise of awareness of the impending shortage of fossil fuels, the alcohol sector begins to reappear in the panorama of national economy making Brasill reaches the point of becoming a leading exporter of this product. Ethanol assumed the role of such importance in Brazilian exports, which Petrobras through the Growth Acceleration Program (PAC) has made investments in the Brazilian pipeline network to better ensure the production of ethanol to major ports. The means of transport in pipelines are safe and inexpensive, but require careful evaluation in its implementation, they may lead to negative social and environmental impacts. Thus, the purpose of this project is to propose the best route for an ethanol pipeline connectin the Tietê-Paraná, leaving the municipality of Santa Maria da Serra (SP), to the Planalto Paulista Refinery (REPLAN), located in Paulinia (SP), belonging to the passage of ethanol export corridor, currently under revelopment. The technique used for the development of the stroke is the association of multicriteria evaluation, the geographical information system (SIG) and geotechnologies. This study presented three possible layouts for the ethanol pipeline, highlighting the best option, in addition, demonstrated the suitability of the area to receive projects of similar nature to a pipeline

To assist the work, developed a project in the company in question in order to analyze and identify applications of concepts of lead time along the supply chain through an exploratory study in order to provide a beneficial outcome to the company through monitoring and performance of its suppliers, which will enable an aid to future decision-making

Utilização do cavaco de madeira como combustível alternativo para a produção de vapor de água em uma caldeira aquatubular com grelha fixa do tipo PIN HOLE

The steady increase in the price of oil and its derivatives, carbon credits, the concern with the environment combined with the precipitation of rain water and lack of water resources that Brazil has suffered in 2014 caused a migration of participation sources of energy in the Brazilian energy matrix. The hydropower sector suffered big drop at 2013 and is suffering so far, contributing thus to the generation and cogeneration of thermal energy using renewable energy sources such as: sugarcane bagasse, wood chips, rice husks, among others. The selling price of the electricity market reached the level of R$ 807, 00 MWh in January 2014 (Source: ANEEL), heating the Brazilian thermoelectric sector. Although thermoelectric use in bulk water as vaporizing fluid to produce electricity and use in various processes, water reuse plans have become an important factor in these industries. The increased use of biomass has been the bagasse which is allied to the sugarcane sector, strong market in Brazil, and consists basically use the rest of sugar cane, sugarcane industries that would play out. The sugar and ethanol industry is very unstable and only lasts for 6-8 months a year, and the remaining time in the period known as between crop that corresponds to the planting and harvesting of sugarcane and then enter the period of vintage which is the constant cane harvesting and crushing it. This instability of the market and the thermoelectric idle period leads the thermoelectric industries to seek other sources of renewable energy, such as wood chips (pine, Eucalyptus, Orange), rice husk, sorghum among others, to not be dependent on alcohol sector. The present work aims to study the use of wood chips as an alternative biomass for burning a fuel that essentially uses bagasse, the thermoelectric in question consists of two boilers that produce together 350 t / h ...

Análise estatística de parâmetros elétricos em usinas sucroalcoleiras do centro-oeste paulista

The industry of sugar cane has become an important contributor to the generation of electricity in Brazil. Currently there are 434 sugar and ethanol plants operating in the country, 23% of the total export electricity to the National Integrated System (SIN), the state of São Paulo has 182 plants and 30% of them export energy to the SIN. The objective of this study is to compare parameters of electrical efficiency in the sugar and alcohol industry. For the study, three plants localized in the midwest region of Sao Paulo state with great potential for production and exporting bioenergy were chosen. Five energy analyzers LANDYS + GYR SAGA were used for measure the electrical parameters. The variables studied were energy consumption (C) and power factor (PF). For the statistical analysis it was adopteda randomized block design in a factorial 3 5composed of three companies and five sectors of energy consumption,in which: reception(1), milling (2), boiler (3), supporting activities / juice treatment (4), and distillation (5), totaling 15 treatments. Each group comprised 192 repetitions (48 hours 4 measurements per hour). It was concluded that there is no interest for the plans to fix the FP and reach a value 0.92, which is considered the ideal power factor.This,because the plants generate their own energy and are not penalized. Regarding the energy consumed, all sectors had significant differences. When comparingsector to sector, the plant called USB showed no significant differences in sectors 1 and 3, and the plant USC, in sectors 1 and 4. Considering the production units of this sector and selling power this type of evaluation is essential to perform this analysis, since the analyzed sectors are most important in the production of sugar and ethanol, and analyze and monitor these parameters, use and consumption energy can provide a greater supply of energy to be commercialized.

Avaliação de sistemas de manejo de palhiço de cana-de-açúcar no campo e na indústria

This work presents and it evaluates the systems of crop of sugar-cane trash for energy ends, through studies accomplished in three industries of sugar and alcohol, of the State of São Paulo, as withdrawal in the field and crop partially integral with separation of the trash in the industry (cleaning the dry). it is Treated of a development of opportunities, because only when there is pulp shortage it is that remembers the energy use of the trash, which presents a larger cost for equivalent ton in energy again that the pulp of the sugar-cane, that already has a very spread trade in the section the sugar and alcohol. Another factor that should be outstanding is the environmental, because the Environmental Protocol exists, sanctioned by most of the producing of sugar-cane, that reduces the period for elimination burned of the sugar-cane before the crop implanted by the Law 11.241 of 2002. However it is important to highlight that the crop of the sugar-cane without it burns her previous, it increases the difficulty in the combat the pest denominated “cigarrinha-da-raiz”, turning necessary the retreat of part of the trash non beneficial for the soil, contributing like this, with the practice of removal of the trash for energy use. Of the obtained results it is ended that the most interesting modality economically, was the separation of the trash in the industry and that for better efficiency, the sugar-cane should go by a double process of blowing for cleaning, pointing out, however, that there was reduction of the capacity of transport of the sugar-cane as adult was the amount of trash partially in the crop integral.

Importância econômica e generalidades para o controle de Telchin licus Drury, 1773 (Lepidoptera: Casttniidae) em cana-de-açúcar

The sugar cane plantation expands its borders each year, throughout the national territory. Thus, increases the amount of biomass that will to be exploited by man in sugar and alcohol produce and also by other organisms, which will have food in abundance. The growth of mechanized harvesting, with the consequent decrease in burning of straw and the expansion of the sucroalcooleiro sector are causing changes into entomofauna in certain areas or regions of sugar cane plantation. One of the new threats to the sugar cane plantations in southcentral region, causing uncertainty and concern to farmers, is the giant worm, Telchin licus, known in Brazil since 1927, in the Northeast of Brazil, is considered a major pest of cane sugar. In 2007 it was first recorded in the state of São Paulo, which accounts for 60% of the country's crops. Whereas until then there is not much information about their management and control, the aim of this review is to gather information on the basis for its control within the context of Integrated Pest Management of cane sugar.
