This work is to show a study, compilation and standardization of laboratory practices taught in Chemistry teaching laboratories of UFMT, which will be suitable according to the principles of Green Chemistry. Analyzing each distinct area of Chemistry, existing practices will be compiled, as well as the development of new researches to cover important topics to build students’ knowledge about the context of Green Chemistry. This work began with a study from experiences already been taught by the teachers themselves, when observing many other similar practices taught by different teachers who chose methodologies and therefore different reagents, glassware, energy sources, which harms a systematic proper collection of waste generated in the lab. In discussions among some technicians and teachers about the practices’ script and the best way to perform them, it was decided that overall classes could have a standardized structure, according to the topics; Name, purpose, theoretical foundation, materials and reagents, procedure and generated waste. The waste generated in practical classes will be highlighted in these work proposals, given the fact that cautions about; segregation, packaging, treatment and disposal are rarely taken into account in the laboratories lessons which were already taught. Topics containing the Green Chemistry principles will be inserted into the theoretical framework when possible, therefore, concerns about atoms economy, energy, and production of hazardous residue, will be discussed and an attempt to raise awareness to everyone involved in class (students, technicians, teachers) regarding disposal, treatment and storage of residue produced, will also be a priority. There is also a proposal for installation of equipment such as infrared and ultraviolet, creating new x practices using these equipment, always seeking to improve the taught classes, as well as a construction project of a single-mode microwave reactor, which will produce less waste in some practices, replacing conventional heating sources for cleaner energy, besides increasing the yield synthesis and extraction and reduce the experimental time. In each teaching laboratory will be placed collectors bottles, that will be from suitable materials and volumes to the type of residue produced more often in that referred laboratory. These bottles are labeled, and by the end of each script practice there is a topic of disposal of residues, which must be followed by students and technicians at the lab, along with the bottle, there will be an identification form for the residue and the person who dismissed, besides the date and amount discarded. Finally electronic and bound handouts will be created, available in General Chemistry, Organic Chemistry, Physical Chemistry, Analytical, Biochemistry and Inorganic Chemistry laboratories, with maximum practice reflecting menus of each discipline always in accordance with the principles of Green Chemistry.
