The adequate bioavailability of nutrients to plants is among the various difficulties of the agricultural sector. Thus, the existence of mechanisms for controlled release of the nutrients is essential for planting, as well as novel techniques that do not cause adverse effects. The use of nanotechnology in agriculture can bring many benefits, such as better use of nutrients by plants, reducing waste. Nanofertilizers are an emerging technology and a constantly expanding class of agrochemicals, representing possible solutions to the development of sustainable agriculture. Based on this, the present work aims to update and discuss some relevant topics about these nanomaterials, such as different synthesis approaches, possible mechanisms for the capture of nanofertilizers by plants, and the advantages and limitations of using these materials. Also, an overview of the main literature in the area is presented approaching current studies that use green chemistry concepts.
Oily wastewater from agro-industries can cause severe environmental and public health damages if unproperly treated. The conventional methods have several limitations for the treatment of oily wastewaters since the oil fraction can cause pipe clogging and biomass washout during the biological step. Based on this, the use of lipases can increase the oil removal efficiency of the treatments, minimizing operational problems,and improving the performance of the biological process. Lipases can also be used for the valorization of the oily wastewaters, transforming these waste streams intovaluable compounds, such as biodiesel, lubricants, antioxidant agents, etc. The use of wastes for the production of value-added compounds followsthe circular economy approach, minimizing the generation of residues and potential environmental liabilities. Thus, this study aims to give a general overview of themain topics related to thetreatment and valorization of oily wastewaters using lipases. The main characteristics of oily wastewaters from agro-industries areaddressed, as well as the most used conventional techniques for their treatment. Some relevant information about the enzyme lipaseisalso discussed to give the reader a background about how these enzymes can be applied for the treatment and transformation of oily wastes.
A agricultura 4.0 está atrelada às inovações tecnológicas de alta performance inseridas no segmento agrícola, em que proporcionam autonomia, flexibilidade, aumento de produtividade e entre outros pontos positivos ao produtor rural. Os pilares da agricultura 4.0 estão pautados na integração da computação, comunicação e controle por meio de redes e processos físicos, ou seja, os sistemas ciberfísicos. Nesse contexto, as tecnologias inseridas na agricultura 4.0 são a computação em nuvem, o aprendizado de máquina, a realidade virtual, a inteligência artificial e etc. E é através dessas ferramentas que é possível a obtenção de insights, modelos preditivos, reconhecimento de padrões, imagens de satélite, sensores, hardwares, softwares e entre outros para a visualização de maneira ampla as necessidades da propriedade e a realização de previsões da produtividade da cultura. Diante disso, o Brasil como um dos principais produtores de alimentos do mundo tem papel importante nesse progresso agrícola, pois sua adesão a essas tecnologias possibilitará aumentar a atual performance da produtividade agrícola e a modernização das lavouras em território nacional. Contudo, um grande desafio para a inserção dessas tecnologias inerentes à agricultura 4.0 é a disponibilidade de internet no campo, pois na maior parte é necessário a integração de computadores e sensores através desse recurso. Assim, a presente revisão objetiva abordar as diferentes ferramentas digitais presentes na agricultura 4.0 e como essas tecnologias podem auxiliar no aumento da produção agrícola ao longo dos anos, seja em aumento de produtividade e/ou na tomada de decisões diante dos desafios da lavoura. Por último, também foram apresentados os potenciais e as limitações da inserção dessas tecnologias no contexto do produtor rural brasileiro e de países emergentes.
