“…Mineral and vegetable impurities significantly affect the production of sugar and ethanol (Lemos et al 2019 ), as the conditions of each stage of the production process must be monitored and controlled to avoid favoring the selection and development of microorganisms that cause undesirable changes to the final product (Duarte et al 2019 ).…”

Graphic abstract This study aims to identify explanatory factors to increase the agricultural performance of Brazilian and Australian sugarcane mills. The relevance of Brazil and Australia for the sugar industry motivated the development this study based on the most important factors in both countries responsible for increasing the efficiency in sugarcane production. Thus, this study is designed to assess the hypothesis that there are a few explanatory variables that are deeply responsible for the agricultural efficiency in the sugar-energy sector. As a specific objective, it proposes a DEA (Data Envelopment Analysis) model that seeks to optimize the production of Total Recoverable Sugar (TRS) by planted area, and simultaneously, minimizes mineral and vegetable impurities. The sample consists of 82 observations from 32 sugarcane mills. An agricultural efficiency study was performed using the two-stage DEA, in which the evaluated mills according to the level of efficiency in the proposed model. Then, a Multiple Linear Regression Analysis was performed to identify the variables with the greatest influence on the performance of the mills in terms of efficiency. The results revealed six relevant variables for increasing the agricultural performance in the production of sugarcane: rainfall (mm weekly), chopped cane delivery (%), delivery time (h), borer (%), air humidity (%), and rods in raw wine (× 10 5 /mL). Finally, semi-structured interviews with Brazilian and Australian experts in the sugar-energy sector allowed the identification of five other relevant complementary factors that were unavailable in the database: genetic variety, agricultural cultivation activities, edaphoclimatic factors, renewal of sugarcane fields and irrigation system. The results of this study were grouped into the dimensions of environment, yield, and impurities, providing quantification and better understanding of the identified explanatory factors and the agricultural performance in terms of production efficiency, offering fundamental information that enables managers to make decisions and prioritize the aspects that contribute more significantly to the increase in agricultural productivity of the planted area.

“…This technique has the potential to predict resource usage and relative efficiency of DMUs based on their performance. It also has the advantage of measuring the efficiency of multiple inputs and/or outputs using linear programming for aggregating different environmental impacts to construct a comprehensive eco-efficiency indicator [27,[29][30][31]. DEA is a common tool for evaluating the agricultural sector and helping to identify how effectively a farmer can produce a certain level of output by applying to other farmers the levels of available input resources [3,30,10].…”

Program (MAP) introduced the "miracle wheat" in 1954 and spread throughout Asia and Africa in the 1950s and 1960s, and the reform continued with other crops like rice and maize [1,2].The reform has increased agricultural production with the use of new technologies, water management practices, mechanization and inorganic chemicals, and made it possible for farmers to produce more agricultural products at lower costs. However, agrochemical input and natural resource intensification generate the pressure of agriculture on natural resources such as soil

“…Ainda, o aumento de impurezas influencia na perda de ART na torta de filtro, visto que a capacidade do filtro na indústria, leva em conta as impurezas minerais, responsáveis pelo aumento do lodo, prejudicando filtragem do caldo obtido após a moagem da cana-de-açúcar (DUARTE et al, 2019).…”

Primeiramente, devo agradecer aos meus pais, Vitória e Benedito Lemos, por todo o esforço e luta pela minha educação, e por terem me criado com valores de resiliência, trabalho e coragem para sempre alcançar meus sonhos. Ainda agradeço também ao meu irmão, Saulo Lemos, pelos momentos de risada leve e descontração. São minha família e minha base.Agradeço ao meu orientador, Professor Alexandre Pereira Salgado Junior, pela confiança na minha formação, por enxergar minha capacidade melhor que eu mesma, pelos constantes ensinamentos, críticas e conselhos que embasaram minha jornada científica.À Professora Perla Calil Pongeluppe Wadhy Rebehy pelas valiosas conversas, aprendizados e por ser para mim um exemplo de mulher na carreira acadêmica.Agradeço a Henrique pelos anos vividos. Aos amigos que fiz em Araraquara,
