It has become almost impossible to imagine what our lives would be like without the many benefits of packaging – just think about the different packaging and single-use items you use on a daily basis. Yet as our global population grows in size and affluence, both our collective demand for packaging materials and the waste we generate as a result will increase dramatically.

Currently, large amounts of packaging waste escape formal collection and recycling systems and eventually end up polluting the environment. Moreover, their material value is forever lost to the economy. The Ellen MacArthur Foundation estimates that uncollected plastic packaging waste alone is worth somewhere between 80 to 120 billion dollars a year.

So how can we improve packaging systems in order to capture this wasted potential? Clearly, the way we currently design, recover, and reuse packaging urgently needs a rethink!

In this course, you will learn about the design of sustainable packaging systems. To do so we will explore the design and business strategies of the circular economy.

Contrary to our current industrial model, which extracts, uses and ultimately disposes of resources, a circular economy is regenerative by design. This means that products and services are reimagined from a systems perspective in order to minimize waste, maximize positive economic, environmental and social impacts, and keep resources locked in a cycle of restoration.

This course is for you if you are interested in learning about sustainable packaging design. You’ll also benefit if you are a professional in the packaging industry and want to learn how to find circular opportunities in your work. Students – particularly in design – will be able to broaden their knowledge of circular design and business strategies.

Life in the city relies on the smooth operation of urban logistics. Everything from retail to services, construction to waste collection rely on an efficient and reliable freight transport system. However, with the increasing pressures of urbanization, this has to be balanced with the environmental and social impacts caused by transport activity. This is the challenge of City Logistics, a field of study that has significant practical implications for the world and the cities we live in. It is not merely a question of what is involved, but what can be done about urban freight transport to improve it for the sake of economic efficiency, quality of life, and sustainability.

From a systematic scientific foundation of the field, this course will take you on a journey to learn how city logistics is understood and practiced in cities around the world. Our instructors, members of a renowned global expert network, will teach you the basics of this highly complex social system. Using their experience in real-world projects, they will illustrate how the knowledge learnt in this course is applied across industry and the public sector.

This course caters primarily to university students or professionals working in urban transport infrastructure planning or logistics management. Whether you are simply curious about the topic or you intend to develop a career in these fields, this course will give you the tools you need to understand the complexities of urban freight transport systems.

The course emphasizes the theoretical foundation, the rigorous evaluation, and a multi-disciplinary approach to this complex area. Course participants will benefit from numerous case studies of best practice in selected cities around the world, in a variety of business settings. Our emphasis on the global perspective is particularly relevant, since an understanding of local culture and political climate is an important factor in the success of any city logistics intervention. The course will provide an avenue for students to learn from their peers about the challenges faced in their respective cities, and how to apply the principles learned to the challenges faced in their own cities.

This lesson is an introductory topic in thermodynamics, on the conversion of energy. The aim of this video is to support students in visualizing the conversion of energy and its importance in real world applications. For this reason, everyday examples are used to help students see the conversion of energy around them. Energy conversion is explored through a simple example of generating electricity for lighting up a shadow puppetry play in a village. The chain process of energy conversion is illustrated until the end product of electricity. This example of electricity generation is further illustrated in an actual industrial setting by taking the viewers to a Power Plant, where viewers will see and hear the explanation of a mechanical engineer on the equipment used to produce electricity that we use in homes and businesses. This important concept of energy conversion is crucial for students to understand as a basis for learning other concepts in Thermodynamics.

This course will focus on basic technologies for the treatment of urban sewage. Unit processes involved in the treatment chain will be described as well as the physical, chemical and biological processes involved. There will be an emphasis on water quality and the functionality of each unit process within the treatment chain. After the course one should be able to recognize the process units, describe their function and make simple design calculations on urban sewage treatment plants.

You will learn the physics behind nuclear science, how to gain energy from nuclear fission, how nuclear reactors operate safely, and the life cycle of nuclear fuel: from mining to disposal. In the last part of the course, we will focus on what matters most in the public debate: the economic and social impact of nuclear energy but also the future of energy systems.

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 basic technical knowledge.
