Biomass and vegetation index by remote sensing in different caatinga forest areas

Ciênc. rural (Online); 52 (2), 2022
Continued unsustainable exploitation of natural resources promotes environmental degradation and threatens the preservation of dry forests around the world. This situation exposes the fragility and the necessity to study landscape transformations. In addition, it is necessary to consider the biomass quan...

El compostaje de cáscara de Musa paradisiaca L. para la producción de biogás y biometano como estrategia de preservación de la salud ambiental

A medida que a se avanza en el siglo XXI, los sistemas de energía deben alejarse de los combustibles fósiles y aumentar la capacidad de las energías renovables si se quieren cumplir los objetivos de temperaturas máximas del Acuerdo de París. Sin embargo, debido a los desafíos en la adopción de tec...

Determination of Bioethanol Production from Apricot (Prunus armeniaca) Pomace

Abstract Fruit juice industry generates massive amount of lignocellulosic by-products annually which are excellent raw materials for bioethanol production. In the current study, bioethanol production from apricot (Prunus armeniaca) pomace by Kluyveromyces marxianus was investigated for the first time. So...

Energy Self-Sufficiency Conditions of Ethanol Autothermal Reforming: a Simulation Study

Braz. arch. biol. technol; 64 (spe), 2021
Abstract Natural gas steam reforming is commonly used for hydrogen production. However, research has shown that ethanol autothermal reforming can produce cleaner hydrogen gas efficiently. Despite this, there is a lack of studies on the energy self-sufficiency conditions of the ethanol autothermal reform....

Potential of Alternative Sources for Electric Power Generation in the State of Paraná

Braz. arch. biol. technol; 64 (spe), 2021
Abstract The State of Paraná stands out in Brazil for its hydraulic potential for electricity generation. Furthermore, the State also shows potential for the use of other sources of energy, such as solar energy, biogas and biomass. The study traces the profile of electric energy consumption and compiles...

Optimal Operation of an Urban Microgrid Using Model Predictive Control Considering Power Quality Improvements

Braz. arch. biol. technol; 64 (spe), 2021
Abstract Microgrids have been widely applied to improve the energy quality parameters of a distribution system locally, in addition to ensuring the operation of the system in an isolated manner. The Model Predictive Control (MPC) is a great solution to guarantee the operation of the system considering fo...

Process conditions for a rapid in situ transesterification for biodiesel production from oleaginous yeasts

BACKGROUND: Microbial oils produced by diverse microorganisms are being considered as alternative sources of triglycerides for biodiesel production. However, the standalone production of biodiesel from microorganisms is not currently economically feasible. In case of yeasts, the use of low-value nutrient...

Abstract Around the world there's a rising interest in the installation of renewable energy sources due to their ecological, economical, political and social advantages. In this article is studied specifically the case of the incentive towards the installation of these sources in the state of Parana's ru...

Integration of Renewable Energy Sources to Operate in Microgrids in Rural Zones in Brazil

Braz. arch. biol. technol; 62 (spe), 2019
Abstract In a world where technology is even more essential, quality and reliability of electrical system are fundamental. In Brazil, country where most of the energy is produced thought power plants, the existing distribution network is overwhelmed and the needs for the consolidation of distributed gene...

Evaluation of Global Heating Reduction Potential with the Replacement of Electricity Supplied by the Local Concessionaire Via Solar Renewable Source

Braz. arch. biol. technol; 62 (spe), 2019
Abstract The objective of this paper is to evaluate, through the 100-year Life Cycle Analysis, Global Warming Potential (GWP) and Global Temperature Increasing Potential (GTP) impact categories. It is proposed scenario of replacement of the energy matrix for the supply of electricity by Solar Photovoltai...
