Special solid waste has been observed at Universidade Federal de São Carlos (UFSCar), campus of São Carlos, and the types of waste have been classified under the following categories: dry recyclable waste (DRW), construction and demolition waste (CDW), yard solid waste (YSW) and laboratorial chemical waste (LCW). It was intended to offer the necessary support in order to achieve a proper management of those types of waste, based on the Agenda 21 and on specific local features. First, data was collected from the specialized literature. Then, field research was held at various Brazilian universities, as well as direct inquiry with the people in charge. Finally the present waste management situation at UFSCar was diagnosed, by identifying the generation sections, and the collection, transportation, treatment and disposal procedures applied at the site. Those procedures or the ones being installed at present were analyzed in order to spot their flaws. Results showed that, although CDW is 4properly collected, it is disposed at dumps around the town without special treatment, causing environmental impacts. DRW, paper specially, is collected to be recycled, but the system presents various management flaws. LCW presented a cumulative stock that should be eliminated by a project in implementation phase, consisting in the proper packing and transportation for incineration. Regarding the LCW to be generated, its management must follow source minimization and prevention procedures before being sent to the Waste Control Center serving the whole campus. YSW is partially used at the university restaurant boiler and as forage at the vegetable garden. The remains are disposed at the rural area of the campus. To improve the special solid waste management at UFSCar, it is necessary to increase the quality on the DRW selective collection, to find better methods of packing and possible recycling to CDW, as well as the complete implementation of the project to minimize and treat LCW.
