No. of bitstreams: 0 Previous issue date: 2018-01-01; PIBIC (Programa de Iniciacao Cientifica da UNESP); The objective of this study was to evaluate the food and water waste in a university restaurant. During the evaluated period, 18,083.08 kg of food were produced of which 17.85% had become solid waste that was disposed in the environment, being that US $...

No. of bitstreams: 0 Previous issue date: 2018-01-01; PIBIC (Programa de Iniciacao Cientifica da UNESP); Restaurants produce large-scale meals, generating large amounts of solid waste, which if not properly managed cause environmental and sanitary problems. Composting is one of the most recommended methods for the treatment of organic solid waste, since th...
The feasibility of using a zinc oxide rich waste (ZnO>95%), dust originated in the brass smelting industrial process, as a raw material to produce targets to be used in radiofrequency magnetron sputtering (RFMS) deposition of ZnO thin films was investigated. The ZnO waste was characterized in terms of chemical and mineralogical compositions and particle size distribution. The targets were prepared by uniaxial p...
Oily sludges are hazardous wastes that contain large amounts of hydrocarbons, water and dissolved solids. A simple distillation procedure was used to fractionate this sludge and isolate a gas phase (10%), and an organic liquid phase (30%) that can be used as fuels. This procedure also separates the water phase from the dissolved solids enabling the independent management of those phases with more appropriated m...
Os resíduos são considerados uma fonte atrativa para a produção de energia, principalmente os de base polimérica. Várias são as técnicas de valorização térmica e energética, como a pirólise, que constituem alternativas com elevado potencial no que concerne à produção de combustíveis alternativos e energia. Estas técnicas, quando aplicadas a resíduos, favorecem a formação de produtos com valor acrescentado. A ut...
