Sugarcane sector has a strong impact as a wealth generator for Brazil. Several authors discuss the importance of quantifying an agro-industrial system. This article aims to analyze the development of the Brazilian sugarcane sector over the past five years and to assess whether the method of mapping and quantification of agribusiness systems (GESis) is a useful tool for analyzing the economic de...
Agricultural and agro-industrial residues (agro-residues) containing high amounts of carbohydrates, such as cellulose and hemicellulose, are produced in large amounts annually worldwide.1,2 Agro-residues are attractive raw materials of biorefinery processes producing value-added products due to their relatively low commercial value, renewability and abundant availability.3 Biorefining of agro-r...
This paper poses and tests a new model of the location of plants that process ubiquitously supplied ‘von Thünen’ inputs such as raw farm output. The new model rationalizes why agro-industry is city-located but resource-oriented. It demonstrates the significance of relative transport costs in agroindustry location. Furthermore, we present a unprecedented direct test/empirical confirmation of est...
Emerging contaminants (ECs) are causing negative effects on the environment and even people, so their removal has become a priority worldwide. Adsorption associated technologies where this process occurs (filtration/biofiltration) have gained great interest, due to its low cost, easy operation, effectiveness mainly in (up 100%) of lipophilic ECs (log Kow > 4). Activated carbon continues be m...
the purpose of this research was identifying mechanisms for the development of human resources in khouzestan sugarcane agro industrial company, iran. this is an applied study and the research method was descriptive correlative. the population consisted of employees working in the sugarcane agro industrial company in the province of khuzestan, iran(n=315). one hundred and seventy five people wer...
Adding value to agro-industrial residues is becoming increasingly important, satisfying needs promote resources’ use efficiency and a more sustainable circular economy. This work performs parametric kinetic study of enzymatic esterification lard tallow with high acidity, obtained by the rendering slaughter by-products, allowing their as feed ingredient increasing market value. After an initial ...
BACKGROUND The plant biomass and agro-industrial wastes show great potential for their use as attractive low cost substrates in biotechnological processes. Wheat straw and corn cob as hemicellulosic substrates were acid hydrolyzed and enzymatically saccharified for high xylose production. The hydrolysate was concentrated and fermented by using Saccharomyces cerevisiae and Kluyveromyces for prod...
