“…In Brazil´s Central-West region, more specifically in MS State (REIS et al, 2016), the off-season is the best economic option in a multi-criteria analysis (logistics, price, availability, and productivity). However, logistics (storage and transport) is the most significant parameter on the decision, and at the same time a bottleneck on the corn production chain; intermodal transport seems to be the best option for higher efficiency (OLIVEIRA et al, 2015). So, considering the strategic necessity of seed/grain storage, the energy availability from residual biomass (husk leaf and cob) can add value to the producer, contributing to products and co-products storage, other than only energy use.…”

After harvest, usually a significant amount of crop residues are available and part of it can be a feedstock for biomass energy. This paper´s objective is to quantify sustainable residual biomass from corn harvesting, husk leaf, and cob, and its solid-fuel characterization for energy co-generation assessment. The methodology considers geographical distributions of corn production on a municipal basis, at Mato Grosso do Sul (MS) State in Brazil. Residual biomass from corn harvest has its mass fractions and energy characteristics determined via proximate and ultimate analyzes, bulk density, and heating values. Also, assessment of energy and power obtained by using co-generation power plants technology. The conclusions identify that residual biomass from corn harvest (husk leaf and cob) have large amounts available for energy use (~190.106 kg), and a main one geographic micro-region at MS. Its characteristics as solid fuel, i.e., HHV~18 MJ.kg-1 and TMC,db

“…Vários trabalhos têm focado na busca por melhorias na logística brasileira. A maioria dos trabalhos têm utilizado modelos matemáticos de otimização do uso da infraestrutura existente para aumentar a eficiência, como Mapa e Lima (2012); Morales et al (2013);Milanez (2014); Oliveira et al (2015); Lima e Ferreira (2016); Oliveira e Alvim (2017) ;Silva Neto (2018); Coleti e Oliveira (2019), entre outros. Em geral, esses estudos adotam as origens e destinos como critérios previamente estabelecidos e, a partir destes, os modelos avaliam a eficiência ou buscam sua otimização.…”

Determinação da área de influência dos portos na logística de exportação da soja de Mato Grosso

No Brasil, o transporte da lavoura até o porto representa uma parcela significativa no preço final das commodities agrícolas. De forma que o planejamento operacional da logística de exportação de grãos é fundamental para melhor a gestão dos custos. A participação do transporte intermodal na movimentação de cargas não está alinhada com a grande extensão territorial, o que impacta principalmente as regiões mais distantes dos portos marítimos. O objetivo do artigo é construir um modelo para determinação da área de influência dos portos brasileiros na logística da soja do estado de Mato Grosso destinada à exportação. O modelo identificou o porto de destino potencial, segundo os custos de transporte referenciados no espaço. A modelagem adotada pode ser também aplicada para avaliação da dinâmica logística de outros produtos agroindústrias. Destaca-se, que em todas as bacias logísticas delimitadas no estado de Mato grosso o escoamento da soja se dá prioritariamente por mais de um modal de transporte. Assim, os portos que influenciaram a logística no estado têm ligações ferroviárias ou hidroviárias, que são acessadas através de rodovias conectadas às regiões produtoras

“…In the study by OLIVEIRA et al (2013), the origin-destination matrix was used to verify the advantages of using intermodality in the routes used to move sugar produced in the state of São Paulo to export ports. In OLIVEIRA et al (2015), this method was used to estimate the optimal export flows of Brazilian maize produced in the state of Mato Grosso to the main export ports of this cereal. The flow of Brazilian soybean occurs through unimodal and intermodal transport systems already discussed in the studies by SOUZA et al 2016; CORREA & RAMOS (2010), where both studies show the economic gains from intermodality.…”

The last Brazilian agricultural frontier known as MATOPIBA, an acronym for the states of Maranhão, Tocantins, Piaui and Bahia, is a region that has stood out in the scenario of modern large-scale agriculture intensive in capital and technology. However, barriers related to the transportation system, especially regarding the high logistics costs, have been negatively impacting this sector. To optimize the performance of this chain, a model for minimizing transportation costs was developed, using linear programming with an origin-destination matrix. The purpose of this paper was to evaluate whether the use of the North-South Railroad has potential as a new alternative intermodal route for soybean export from the MATOPIBA region, in order to minimize the transportation costs and promote the viability of new ports located in the northeast region of the country. This configuration can also contribute to reduce the overload of Santos Port (SP). Two scenarios were proposed based on the 2016/17 harvest of soybeanwhere the first scenario (A) consisted only of road routes, while the second (B), in addition to these routes, incorporated road-rail and road-water way intermodal routes. As a result, total transportation cost was reduced by 30% in scenario B and about half of all cargo was shipped by the new intermodal road-rail route to the Itaqui Port in the Northeast region. This configuration promotes a more sustainable logistics chain for soy, with more rational use of transport modes and decentralization of investments to other regions.
