2. Evaluation of the Properties of LaNiO3 Material Prepared by the Modified Proteic Method for Adsorption of Environmental Contaminants
LaNiO3 material was synthesized by modified proteic method, calcined at 900 °C/2 h in air atmosphere and was applied to remove environmental contaminants. LaNiO3 phase with a perovskite structure was formed in the calcined material, which has a surface area of 22 m2 g-1 and is formed by fine particles agglomerated, with pH of the zero charge point of 7.44.

5. Thermal characterization of soil-cement bricks using mining tailings
Abstract Soil-cement bricks are earth construction materials that have been gaining prominence due to their environmental advantages. The Brazilian Technical Standard NBR 8491 establishes physical and mechanical procedures to characterize these bricks. However, the thermal characterization is an important assessment, since it is related to the building’s t

6. 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

7. Optical sorting technology for waste management from the Boukhadra iron ore mine (NE Algeria)
Abstract Mining processes in the iron ore mine of Boukhadra, Tebessa (NE Algeria) generated thousands of tons of mining wastes every year, which represents a real threat to the environment, leading to hazardous effects for the resident population of the region. The aim of this study is the selective sorting of the Boukhadra mining wastes for valorization. Th

8. Selective formation of neodymium phosphate from iron-neodymium magnet waste
Abstract Neodymium-iron-boron alloy, Nd2Fe14B, is used as a material for magnets. Neodymium is one of the valuable and expensive rare earth elements and is often recovered to reduce costs and environmental impact. Recently, a method for recovering neodymium as neodymium phosphate from mixed solutions was reported. This method was very useful because the main

11. Agro-Industrial Waste Valorization: Transformation of Starch from Mango Kernel into Biocompatible, Thermoresponsive and High Swelling Nanogels
Mango industry processing disposes 40-60% of this fruit as residues, such as peels and kernels. The exploration of bioproducts from these industrial rejects can reduce environmental impact besides of producing high value-added materials. In this scenario, carboxymethyl starch nanoparticles were produced from mango (Mangifera indica L.) kernel starch. These n

12. Chemical Characteristics and Antioxidant Activity of Astaxanthin Extracted from Shrimp Residues Using Soybean Oil
Shrimp residues generated by the seafood industrial processing are generally discarded in the environment without any further treatment, leading to a loss of nutritional value such as proteins, lipids, chitin, carotenoids, and minerals. This practice can lead to environmental problems due to the decomposition of these substances in the air. The objective of
