New approaches are needed to reduce emission of contaminants of emerging concern (CECs). Some sources contribute strongly to such emissions, which has driven the focus of PRESAGE on innovative decentralized wastewater treatment (WWT). An integrated analysis of the behaviour of organic micropollutants (OMPs), antibiotic resistant microorganisms and genes (ARMs/ARGs), pathogens and viruses …
The main goal of this Research Project is to establish the fundamental bases to apply the biorefinery concept to a biological wastewater treatment plant, with generation of bioenergy and high value-added products. Such conception is based on the use of anaerobic reactors as the core technology in a wastewater treatment plant, mainly because this process generates a broad spectrum of organ…
Mass spectrometry is a method for identifying the different atoms that compose a substance. A mass spectrometer bombards a substance with electrons to produce ions, or electrically charged atoms. The ions cross a magnetic field that curves their trajectories in different ways, depending on their mass. The field separates the ions in a pattern known as the mass spectrum. The mass and the c…
The advances of the last few years in the municipal and industrial wastewater biological treatment have been supported by basic and applied research involving mainly the fundamental aspects of the processes and the development of innovative bioreactors. A sound and thorough knowledge of the basic phenomena, together with the development of the engineering of biological reactors have opene…

This study has as main focus the elaboration of a diagnosis and to propose actions for maintenance and improvement of the quality of the waters in an inhabited area within an area of Atlantic Forest, under the domain of the Instituto Terra Luminous (ITL). As it is a place characterized by having a seasonal generation of sewage and by being located in a preserved area, the common sewage tr…
Researches for renewable energy sources is increasing considerably nowadays, due to a possible shortage of fossil fuels in the future. In this sense, a promising alternative for clean energy is the treatment of domestic or industrial effluents using the anaerobic digestion process in bioreactors, in which microorganisms degrade complex organic matter and converts it into biogas, hydrogen …
Vinasse, a by-product of sugarcane processing, is a source of nutrients such as calcium, magnesium and potassium. For that reason, its main destination is the fertigation. However, vinasse has high concentration of solids and organic matter, acidity and a high sulfate content, which can affect the productive quality of the soils. Therefore, the previous treatment of vinasse before its use…

One of the biggest challenges of the Brazilian sugar-energy sector is the management of vinasse from the ethanol production process. Recently, technologies based on the sustainability of this process have been developed where it is possible to simultaneously treat vinasse and recover energy in the form of biogas to supply energy in the plant itself. However, the high concentrations of sul…
It is growing need for the development of new technologies for the production of renewable energy, due to the possible depletion of sources fossil fuel and because they are polluting. Therefore, new methods and technologies for the generation of biofuels have been developed, such as hydrogen. Hydrogen is energy carrier clean, abundant in the universe and renewable, and an effective way to…
Giving the growing global demand for natural resources, associated with the limitations in fossil resources availability, the search for renewable energy sources and feedstocks becomes imperative to maintain the continuous technological development. In this context, the concept of biorefinery applied in the treatment of wastewaters characterizes a promising alternative due to the potentia…

In this context, a promising alternative for clean energy is the treatment of domestic or industrial effluents using the anaerobic digestion process in bioreactors, in which microorganisms degrade complex organic matter and convert it into biogas,hydrogen or methane. …
Sugarcane vinasse, a byproduct of ethanol production, is currently being used as a fertilizer in the agricultural sector in Brazil. However, fertirrigation in excess and for long periods has caused environmental problems such as soil acidification and contamination of ground and surface water, among others. Classical ecotoxicological assays (survival and reproductive endpoints) have been …
The relevance of fundamental research on how a micropollutant is biologically converted into less toxic and persistent chemicals is the first step to apply biochemical knowledge on industrial processes. Even though Tetrabromobisphenol A (TBBPA) is the most used flame retardant worldwide and is often detected in wastewaters and water bodies, its biodegradation is poorly understood. The com…
The production of VFAs from organic wastes and residues by anaerobic fermentation is a promising technology and the use of microbial mixed culture fermentation is encouraged due to its various operational and economic advantages. The main limitation that prevents its industrial applicability is a lack of precise understanding of how different organic fractions are biotransformed into diff…
The application of a biorefinery approach in agro-industrial mills relies on the recovery of the waste and wastewater. For the harnessing of lignocellulosic biomass, a pre-treatment is necessary. However, releasing the monosaccharides present in biomass, like glucose and xylose, implies in the release of phenols and furans, which compose the lignin. These compounds are considered recalci…
