How can we ensure the continuous supply of the increasingly scarce raw materials that are needed to make the products we use every day? In this course, we will look at the potential benefits of circular procurement and how recycling technologies and more efficient ways of collecting and recycling critical raw materials (CRMs) can make your business and production more resource resilient. A good number of the materials found in everyday products are now referred to as “critical”. This means that there is a risk of failure in their supply and that they are also critical in terms of economic importance. Many metals, for instance, are already critical or could become critical in the near future due to their limited availability and the growing demand for products worldwide. Think of the newest electronic products that contain critical metals such as gallium, which is used in integrated circuits; beryllium, used in electronic and telecommunications equipment and permanent magnets and germanium found in infra-red optics. Innovative product design and reusing, recycling and remanufacturing products can help to deal with a raw materials shortage. But this can only provide an integrated solution if we keep CRMs in the loop through smarter CRM management. The starting point is to identify CRMs in products. It is not always clear what materials are in which products. It is, therefore, necessary to keep all metals in the loop for as long as possible. Scarcity in the supply chain can not only damage businesses but also negatively impact economic development and the environment. For this reason, the course will also discuss environmental issues and electric and electronic waste regulations. This course will be of value to a wide range of professionals working in or interested in this field. These include professionals involved in producing products containing CRMs (such as electronics) as well as local or national government officials tasked with organizing waste management and recycling for these products. Students interested in the field of waste management will also find this course helpful for their studies in electronics, industrial design, and industrial ecology.

Reduction of energy consumption of buildings is an important step in the move towards a sustainable economy. How can buildings be made net zero energy, in different climates? This course introduces you to zero energy design. It will teach you a stepped approach to design a zero energy climate concept for existing buildings: homes, schools, offices, shops etc. It will demonstrate how an integrated approach, which takes into account both passive measures (such as thermal insulation and sun shading) and active measures (such as heat pumps and photovoltaic panels), can deliver the best results. It will do so by providing you with an overview of possible measures, and through reviewing several case studies of zero energy buildings in the Netherlands, with lessons for other climates as well. Thus, you will learn which measures are most suitable for individual buildings under local climate conditions. This course is for anyone interested in making buildings more energy efficient, who already possess asic technical knowledge.
