Solid Waste Treatment Plant Design


The main objective of this course is to prepare the student through the design of a project for the treatment and final destination of waste on a site whose topography is real, in order to apply academic knowledge to a real project built or to be built, which allows you to understand what your future professional life will be like in practice. At the end of this course it is expected that students have recovered knowledge from previous years and acquired new skills for application in the project, namely in the area of geotechnics, geology and sanitary and civil engineering. It is also an objective to promote the students'''' visit to identical works in operation to confront the exposed material, remove doubts and adjust the reality to the acquired concepts.

Teaching method

The teaching method is carried out in theoretical classes and theoretical-practical classes, with the design and execution of an execution project (taken from the real situation) that is attributed to it. The student is continuously monitored, doubts are clarified, knowledge is consolidated, concepts of concept are discussed, challenges are proposed in order to find solutions and the technical approaches necessary for the development of work are transmitted to students, in similarity to future professional life outside the university. The evaluation is continuous with an oral presentation and technical discussion of the execution project conceived in the context of future professional life.

Evaluation method

The evaluation is carried out continuously, contemplating the elaboration of 4 (four) practical work in groups and culminating in the oral presentation and technical discussion on the execution project conceived and obtained results, consolidation of concepts and identification with the professional life to continue abroad from college.

The final classification is obtained by applying the following formula:

CF = 0.40 x PE + 0.40 x TP + 0.20 x DO

Where CF is the final grade of 20 values, PE = execution project, TP = practical work (0.10 each work) and DO = oral discussion
