Objectives

This course aims to provide students skills in all aspects related to energy recovery; pollution reduction at source; end of pipe technologies for the treatment of effluents and wastes; life cycle assessment (LCA) methodology and its potential applications; environmental, economic and societal sustainability, impacts of products and/or processes.



 

Learning outcomes and competences

1. Technical knowledge and reasoning
1.1 Core engineering fundamental knowledge: energy recovery, reduction of pollution.
1.2. Assessment of potential environmental impacts, associated with a product life cycle; sustainability assessment of products and/ or processes.
1.3 Knowledge in advanced engineering: end of pipe treatments.

2. Personal and professional skills and attributes
2.1 Professional skills and attitudes: to acquire know-how in structuring an LCA study, distinguishing this tool from other analytical instruments and/or environmental management tools; employing eco-indicators; understand the growing influence of the interested parties ("stakeholders"), of international law and current or even future treaties, and the environment in which businesses operate, for instance adding more value to products and/or services, and obtaining competitive advantages; understand the strategic implications for companies in the short to long term, including practical aspects such as the sustainability report, the need to be more proactive in this area, and how innovation and development of a new product or business model can be promoted based on the opportunities created by sustainability.

3. Interpersonal skills
3.1 Teamwork: Coaching and development of teamwork.
3.2 Communication in foreign languages: English.

4. Conceiving, designing, implementing and operating systems
4.1 External and societal context: notions of environmental and economic sustainability.
4.3 Conceiving and engineering systems: concepts of process integration; waste recovery.
4.4. Designing: design of energy facilities; solutions to reduce pollution in industrial facilities.

Eligibility for exams

Attendance to classes according to general rules applied at FEUP

 

Calculation formula of final grade

Distributed evaluation with two tests (T1 and T2) and one report (R).

The test T1 will focus on the first module of EQS, which addresses energy efficiency and thermal engineering. Estimated date: November 19.

The test T2 will focus on the life cycle and sustainability assessment. Estimated date: December 3.

The report R will focus on the life cycle and sustainability assessment. Estimated deadline: December 10.

Final Mark (CF) will be based on the sum of the three components considering their respective weights (CF = 0.5 T1 + 0.2 T2 + 0.3 T3). 

Note: Students have to reach a minimum grade of 10 for CF and 7 out of 20 in the individual components T1, T2 and R.

 

Examinations or Special Assignments

Not applicable

 

Special assessment (TE, DA, ...)

An exam which will cover all of the subjects of the course.

 

Classification improvement

Can be applied to all the components.
