Prerequisites

Having completed the subject of Matter Fluxes and the Water Cycle.

Objectives

The objectives of this subject are:

  • Critically analyze the waste management cycle in urban environments, including the stages of generation, collection, treatment, recovery and final disposal.

Face-to-face teaching is structured into lectures and problem-solving sessions, which are coordinated to promote the integration and application of course content. Problem-solving sessions may incorporate, when appropriate, new conceptual elements required for the completion of in-class assessment activities.

Both lectures and problem-solving sessions include assessable learning activities, which may be carried out individually or in groups, depending on the specific objectives of each activity.

The course includes the development of a group project throughout the semester. The assessment of this project is based both on process monitoring—through meetings scheduled at the beginning of the course—and on the quality of the final deliverable.

The course also includes a mandatory technical visit. Students who are unable to attend for justified reasons (as defined by the regulations of the School of Engineering regarding exam rescheduling) must complete an alternative assessment activity. This activity is compulsory to pass the course and requires a minimum grade of 5.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment Process and Activities

The course is assessed through the following components:

  • Examinations: Two midterm exams are conducted during the course, each accounting for 38% of the final grade. These assessments cover content addressed in face-to-face sessions (lectures and problem-solving sessions) as well as the technical visit. The second midterm may include content previously assessed in the first.
  • Group project: Accounts for 24% of the final grade and is non-recoverable.
  • In-class assessment activities: These may contribute up to an additional 0.6 points to the final grade obtained from the exams and the group project, with the final grade capped at 10. In the overall calculation, activities associated with the first midterm account for 75%, and those associated with the second midterm for 25%.

The minimum requirements to pass the course are:

  1. First midterm: 5
  2. Second midterm: 3,5
  3. Group project: 5
  4. Overall final grade: 5

Scheduling of Assessment Activities

Examinations are held in accordance with the official degree examination calendar.

In the event of being unable to attend an assessment activity that accounts for more than 20% of the final course grade, or whose completion is mandatory to pass the course, students must comply with the regulations established by the School of Engineering.

Resit Process

The resit process is intended exclusively for students who have not passed the course through continuous assessment.

Midterm exams are considered eliminatory when a grade equal to or higher than 5 is obtained.

During the resit process, the final grade is calculated using the same criteria as in continuous assessment, including the established minimum thresholds.

The group project and in-class assessment activities are non-recoverable.

Review of Grades

For each assessment activity with a weight exceeding 25%, an on-site review session is scheduled, with prior indication of time and location. During this session, students may submit grade appeals, which will be evaluated by the teaching staff. Failure to attend this review session implies waiver of any subsequent review.

For the remaining activities, students have a period of 48 hours from the publication of the grade to request a review.

Here is a clear and academically appropriate translation into English, maintaining the formal and regulatory tone:

Grading

The awarding of the distinction “Matrícula de Honor” (MH) is the responsibility of the course instructors. According to UAB regulations, this distinction may only be granted to students who obtain a final grade equal to or higher than 9.0, and to a maximum of 5% of the total number of enrolled students.

In this course, eligibility for this distinction additionally requires having obtained a grade equal to or higher than 8.5 in all assessment activities and not having required any resit examination.

If the course is not passed because one or more assessment activities do not reach the minimum required grade, the numerical grade recorded in the academic transcript will be the lower value between 4.5 and the weighted average of all grades. Exceptions include the assignment of a “Not Assessed” grade to students who do not participate in any assessment activities, and that the numerical grade recorded will be the lower value between 3.0 and the weighted average in cases where the student has committed irregularities in an assessment activity.

Use of Artificial Intelligence Tools

The use of artificial intelligence tools is not permitted in any assessment activity unless explicitly stated otherwise.

Academic Misconduct: Cheating and Plagiarism

Without prejudice to any additional disciplinary measures that may be deemed appropriate, and in accordance with current academic regulations, any irregularities committed by a student that may lead to a change in the grade will be marked with a zero (0). Assessment activities graded in this way are not eligible for resit.

If passing any of these assessment activities is required to pass the course, the course will be automatically failed, with no opportunity for resit within the same academic year.

Such irregularities include, but are not limited to:

  • Total or partial copying of an assignment, report, or any other assessment activity
  • Allowing another student to copy
  • Submitting group work not fully completed by all members of the group
  • Presenting materials produced by a third party as one’s own, including translations or adaptations, or generally submitting work containing elements that are not original to the student
  • Having communication devices (such as mobile phones, smartwatches, etc.) accessible during individual theoretical or practical assessment tests (examinations)

Single Assessment

Single assessment includes content covered in both lectures and problem-solving sessions and consists of:

The two midterm exams, with the same characteristics as in continuous assessment (68% of the final grade), maintaining the same minimum grade requirements.

An oral assessment consisting of the presentation of a previously assigned topic, followed by a question session on both the presentation and the course content (24% of the final grade). This component is non-recoverable and requires a minimum grade of 5 to pass the course.

The single assessment will take place on the same date as the second midterm exam. If a resit is required, it will be held on the officially scheduled resit date. The same recovery system will be applied as for continuous assessment.

Second and Subsequent Enrollments

Upon request, students may retain grades from assessment activities, the group project, and midterm exams that have been passed.
