Materials and Recycling

Recommended Prerequisites

Physics and Chemistry.

Teaching Methods

The teaching methods adopted have as main goal the fundamental knowledge of advanced technologies. Thus, in addition to presential formal lessons of key themes that integrate the syllabus, in which will be taught the basic concepts and stimulate discussion on its importance for the future engineers, an attempt is made to pass from the technology to the product. The classes will be supported by visits to industries. Theorico-Practical classes consist of group working on actual technology in analyse and have the objective to develop a critical view. Proactive stance will be encourage.

Learning Outcomes

Acquisition of knowledge to select, monitor and adapt methodologies of recycling to the production of new components or even systems with the quality required. Ceramic or even metallic powders, the powder technology for the manufacturing of ceramic and metal components opens a new perspective to the different recycling waste constituted by powders. The acquisition of skills in powdertechnology is a necessity for recycling. Polymers are one of the causes of the presence of huge amounts of waste, learn to distinguish them from effectively and meet their essential properties to be taken into consideration after their recycling in order to assess its effectiveness for a target application. Composite materials are those who by their origins are more difficult to recycle, thus the knowledge of the possible varieties and their limits before recycling can facilitate the adoption of solutions.

Syllabus

Knowledge of the material to a true Environmental Engineering. Properties of materials and performance in service of the parts/devices/system. Fundaments of science and engineering of materials; Crystalline materials and amorphous versus structural properties; Structural defects versus properties – vacancies, interstitial atoms, substitution atoms, dislocations, grain boundaries, stacking faults. Semi-crystalline materials – the importance of glass transition temperature versus melting temperature. Memory effects. Types of materials with industrial interest. Metallic alloys; heat treatments; recycling and limitations of properties. Ceramics and Glass types: traditional and techniques; processing; exceptional properties of ceramic materials; types of glass; processing; recycling ceramics: processing and properties; ceramics as receivers of waste; glass and recycling. Polymers types; properties; applications versus glass transition and melting temperatures. Composites. Nanomaterials.
