Prerequisite or corequisite units are presented within each program
Learning unit contents
The course is centered around the questions how recycling could contribute in overcoming materials shortage and what is the economic importance and technological challenges in management and recycling of "secondary" resources;
The main topics to be outlined during the course are:
Introduction to solid waste management, urban mining concept, product life cycles and circular economy of metals. Raw materials demand/supply trends. Emerging technologies and demand for critical raw materials. Current situation in the area of metals recycling. Recycling efficiency. Design for recycling and design for disassembly. Recycling activities as a complementary to primary mining in securing metals supply.
Examples of specific fragmentation, components liberation and material separation units developed for the waste processing industry (shredders, automatic sorters, eddy-current and ballistic separators).
Basic flow-sheets developed to (re)processing solid wastes will be given, focusing on the following case studies (non-exhaustive):
* Recycling of end-of-life batteries
* Recycling of end-of-life vehicles
* Recycling of plastics and composites
* Recycling e-scrap (WEEE)
* Municipal soild waste - energy and material valorisation
Learning outcomes of the learning unit
By attending the course students will be able to:
- understand the role of supply of economically important raw materials for the driving emerging technologies
- be aware about resources scarcity and importance of the circular economy of metals
- understand the notion of "urban mining" and secondary resources
- get glance of the principles of solid waste management and the associated legislative basis
- get acquainted how unit operations known from the mineral processing technology are adapted in treatment solid wastes and by products
- identify the principal challenges in recycling of secondary resources (characterization, equipment selection and arrangement)
- understand the basis steps during elaboration of solid waste recycling/treatment technologies
Prerequisite knowledge and skills
It is advisable that the students possess basic knowledge in metals supply chain and solid-solid separation techniques
