13. Exergy and emergy: complementary tools for assessing the environmental sustainability use of biosolids generated in wastewater-treatment plant for energy-production
Taking advantage of the energy contained in the biosolids generated in a wastewater treatment plant (WWTP) is one of the processes of greatest interest due to the opportunity to obtain an energy resources from a waste. The aim of this research was to analyze the environmental sustainability use of biosolids generated in a wastewater-treatment plant for energ

16. Drum-drying of mango peel and characterization of different varieties
RESUMO A casca da manga, um subproduto da indústria de polpa, é rica em nutrientes, porém com alto teor de umidade. A secagem é indicada para estabilizar o resíduo e o uso do drum-dryer é uma alternativa pouco estudada. O presente estudo avaliou a aplicação da tecnologia para cascas de manga, investigando as condições de processo. O potencial das c

18. Mathematical modeling of whey foam mat drying
ABSTRACT This study aimed to fit mathematical models to whey foam drying processes in different air temperature conditions, to determine the effective diffusion coefficient and to obtain the activation energy. For foam formation, 5.0% Emustab® was added to the serum in mass and subjected to stirring in a domestic shaker for 15 min. After, it was spread onto

19. Traditional sour cassava starch obtained with alterations in the solar drying stage
Abstract After natural fermentation and solar drying, sour cassava starch acquires expansion property. Traditionally, solar drying occurs without protection, and consequently physical contamination can arise. Thus, the aim of this study was to produce sour cassava starch using a low-cost solar dryer to prevent contamination, whilst retaining the expansion pr

21. Influence of the physical characteristics of sand and the crushed filler content on the properties of self-leveling mortars
Abstract The properties of self-leveling mortars (SLMs) in the fresh and hardened state are strongly affected by their formulation. In this study, the influence of three different quartz sands (different physical characteristics) was investigated in SLMs, as well as the replacement of these sands by crushed basalt filler. The tests performed were: spreading,

22. Evaluation of the combined addition of aluminum lactate and calcium carbonate to alumina-based castables
Abstract Calcium aluminate cement (CAC) can induce the development of high green mechanical strength to refractory castables in a short period of time (24 h). However, the production of this hydraulic binder is energy-intensive and releases a large content of carbon dioxide (CO2), which adds to global warming. Thus, aiming to develop an alternative binding s

23. Chemical and antioxidant characterization, sensory and shelf-life analysis of cereal bars with almonds from pequi (Caryocar brasiliense Camb.)
Abstract The study aimed to know how almonds from Pequi (Caryocar brasiliense Camb.), a byproduct of this fruit from Brazilian Cerrado, can be used to improve value to cereal bars. To respond to this question, the study characterized pequi almonds and cereal bars with pequi, and evaluate sensory acceptance. The preparation of cereal bars enriched with pequi
