1. 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

2. Obtainment of a new metal matrix composite from the recycling of UNS S31803 duplex stainless steel by powder metallurgy
Abstract The purpose of circular economy is to maximize resources efficiency. With the increase in consumption of raw materials, energy and waste generation, recycling is necessary for environmental and industrial reasons. Thus, the powder metallurgy, together with mechanical milling, stands as a new method for scraps recycling. This study aimed to produce U

3. New treatments for rare bone diseases: hypophosphatemic rickets/osteomalacia
Abstract Phosphorus is one of the most abundant minerals in the human body; it is required to maintain bone integrity and mineralization, in addition to other biological processes. Phosphorus is regulated by parathyroid hormone, 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], and fibroblast growth factor 23 (FGF-23) in a complex set of processes that occur in the gu

4. Using static, kinetic and metal mobility procedures to evaluate possibilities of coal waste land disposal at Moatize Mine, Mozambique
Abstract Coal mine waste rocks produced during mining and beneficiation can affect the environment due to land degradation and acid mine drainage generation. However, proper characterization and treatment of mineral processing wastes creates options for safe disposal, enhancing the environmental performance. The aim of this study was to use static and kineti

5. HPLC METHOD IMPROVEMENT FOR 4-NONYLPHENOL DETERMINATION IN ANAEROBIC REACTORS: DECREASING SOLVENT CONSUMPTION AND WASTE GENERATION
The aim of this study was to develop a chromatographic method for 4-NP determination in anaerobic batch reactors using low amount of organic solvents and also evaluate 4-NP degradation in the presence of different co-substrates. Chromatographic parameters was improved for stationary phase (C-8 column), mobile phase (acetonitrile/water solution 90:10, v:v), c

6. ECONOMIC MANAGEMENT MODEL OF ELECTRICITY GENERATED FROM BIOMASS IN A PIG FARM
ABSTRACT Faced with the increasing demand for renewable energy, researchers have developed several ways to generate them, such as biogas. Thus, the present study aims to demonstrate the economic viability of electricity generation from biodigesters in a pig farm to contribute to sustainable development by reducing pollution in the environment. Studies focuse

7. AVALIAÇÃO DE ADITIVOS DE FASE MÓVEL E TEMPERATURA NA VIDA ÚTIL DE COLUNAS PARA CROMATOGRAFIA LÍQUIDA DE ALTA EFICIÊNCIA
Buffered solutions, additives, and column temperature are widely used in high-performance liquid chromatography to promote adequate retention of compounds and to improve the chromatographic separation. However, these factors can dramatically reduce the column lifetime. In this work, the effect of column temperature, pH and the salt type and concentration in

8. REUSE OF COLLAGEN AND HYDROXYAPATITE FROM THE WASTE PROCESSING OF FISH TO PRODUCE POLYETHYLENE COMPOSITES
In recent years, the increase in the generation of waste (e.g., bones and skin) from the processing of fish-based food related to the increase in fish consumption and the accumulation of synthetic polymers in the environment are causing major environmental concerns. Hydroxyapatite (HA) extracted from the bones and collagen from the skin of fish processing re

11. Energy Potential of Animal Waste in the State of Paraná (Brazil)
Abstract Animal biomass is a source of energy commonly discarded without or with low utilization, but its availability draws attention to its reuse [1]. The utilization can be carried out in different ways, varying in terms of generation time and efficiency. The use of biodigestion requires a relatively small area compared to landfills or natural composting,
