Collaborative logistics and eco-efficiency indicators: an analysis of soy and fertilizer transportation in the ports of Santos and Paranaguá

Abstract

The present study aims to investigate the use of collaborative logistics between soybean export and fertilizer import operations in the main logistical corridors in the state of Mato Grosso to the ports of Santos and Paranaguá, aiming to identify, analyze and propose an indicator of eco-efficiency that seeks to reduce the financial and environmental impacts of this practice. For that, two scenarios were analyzed, namely: base and ideal. In the ideal scenario, the entire imported fertilizer load participates in collaborative logistics. The base scenario was defined by applying a questionnaire to 96 drivers working in the ports of Santos and Paranaguá, thus identifying the incidence of trucks that return loaded from the port areas with fertilizers. Comparing the base scenario with the ideal scenario, the potential impact regarding the costs of road transport of fertilizers is around R$ 14,696,509.89 in the port of Santos and R$ 11,806,055.10 in Paranaguá, totaling R$ 26,502,564.99. In the ideal scenario, there was a reduction in CO2 emission during 2018 in the order of 29.48 kg CO2 per ton transported in the port of Santos, with the reduction obtained in Paranaguá was 14.38 kg CO2 per ton.

The Concept of Sustainability in the Brazilian Road Freight Transportation Sector

“…Road transportation is a complementary modality par excellence in different situations of cargo transposition, since it is through trucks that different loads leave the production source and reach the railways, airports or ports [20].…”

Analysis of activities that generate logistical costs in an operation in Brazil to import a containerized cargo: a case study

“…The second group of works consisted of cost data from specific companies, having been carried out based on interviews, questionnaires, and other forms of data collection in the focal companies (Aulin et al, 2019;Duraccio et al, 2015;González-Ramírez et al, 2020;Ishii et al, 2016;Laraswati et al, 2016;Peng et al, 2019;Soliani et al, 2020;Wiratchai et al, 2018).…”

Roteirização de Veículos: Uma Aplicação do Problema do Caixeiro Viajante no Setor de Alimentos

“…De acordo com Chen et al (2019), a seleção de rotas ótimas para a realização de entregas minimiza o custo de transporte em relação ao valor da venda do produto. A redução dos custos deve-se à diminuição da quilometragem rodada, a consequente redução dos custos de manutenção dos veículos, gastos com combustível e maior aproveitamento da capacidade de carga do veículo (SOLIANI et al, 2020). Cattaruzza et al (2017) enfatizam a importância da roteirização para as organizações, uma vez que se obtém benefícios significativos, tanto em relação às despesas operacionais quanto na qualidade da prestação dos serviços.…”
