Biomass is the only renewable feedstock which contains the carbon atoms needed to make the molecules to create chemicals, materials and fuels. However, the majority of our current scientific and industrial knowledge on conversion is based on processing fossil feedstocks. In this course we explore the relevant fundamental knowledge on (bio)catalytic conversion in order to produce (new) biobased building blocks, chemicals and products.

The design of an effective (catalytic) process for the conversions of biobased feedstocks to desired products is the core of this course. Unique for bioconversion is the presence of the elements O,N, P, S and the large quantities of water.

We therefore will explore:

  • microbial, biochemical and chemical (i.e., catalytic) conversion routes.
  • how to use catalysts, either heterogeneous, homogeneous or biocatalysts function in order to optimize the process of conversion. We discuss how these catalysts can be tuned and their specific advantages and disadvantages for biobased conversions.
  • the influence of the reactor choice as an inevitable asset in the process. We discuss how to describe the productivity of catalytic processes depending on the choice of the reactor and how the choice of the reactor can add to the stability of the conversion process.

The knowledge you gain allows you to design processes specifically targeted on biomass based conversions as well offering an opportunity to interact with chemist, engineers and scientists who mainly focus on the traditional fossil based conversions.

In a biorefinery a complex biobased feedstock is separated and processed in such a way that sustainability and application opportunities are maximized. In this course we will focus on tools and techniques to efficiently disentangle, separate and convert different biomass based feedstocks into simpler (functional) components.

First we will discuss available techniques and processes for biomass activation/disentanglement and separation.

Next we explore how to design a biorefinery taking into account feedstock and sustainable energy use. Therefore we will dive into:

  • mass and energy balances;
  • design of biorefinery process units to obtain multiple products from one type of biomass;
  • how to recover energy and resources in the biorefinery system;
  • evaluation of the designed system with respect to sustainability and economic criteria;
  • evaluation of criteria for successful implementation (operational and investment costs).

Explore how to create a sustainable future by moving away from dependence on fossil resources to biomass resources for the production of food, chemicals and energy-carriers.

We’ll focus on five topics in this course:

1. Introduction to Biobased Sciences

Learn about the products that can be derived from biomass and the processes used to do so, compared to current fossil based products and processes.

2. Biorefinery

Biorefinery deals with the challenge of extracting valuable biomass components and converting them to final products. To achieve this you first need knowledge of the different types of biomass, the molecules present and their chemical characteristics. Biorefinery is all about efficient processing. Aspects of processing include the harvesting, pre-treatments, conversion and separation technologies.

3. Consumer Behaviour

Understand the challenges of moving towards a biobased economy and gaining consumer acceptance. How do consumers evaluate products? And how is their perception influenced by communication strategies?  Understanding the basics of consumer science will help you to implement a consumer view when developing a product. 

4. Biomass production

A biobased economy runs on biomass. It is therefore important to understand which factors play a major role in crop growth, yield formation and quality. In this module you’ll learn to identify design criteria for the production of biobased crops on both a crop and farm level.

5. Achieving Sustainability

Delve into the true meaning of sustainability and how sustainability issues are linked to human activities. Biobased products are not always as sustainable as it seems on first glance. You’ll learn that an understanding of the degree of sustainability requires a thorough analysis of a variety of factors and constituents.

Physics 101 is the first course in the Introduction to Physics sequence. In general, the quest of physics is to develop descriptions of the natural world that correspond  closely to actual observations.  Given this definition, the story behind everything in the universe is  one of physics.  In practice,  the field of physics is more often limited to the discovery and refinement of the basic laws that underlie the behavior of matter and energy.  While biology is founded upon physics, in practice, the study of biology generally assumes that the present understanding of physical laws is accurate.  Chemistry is more closely dependent on physics and   assumes that physical laws provide accurate predictions.  Engineering, for the most part, is applied physics. In this course, we will study physics from the ground up, learning the basic principles of physical laws, their application to the behavior of objects, and the use of the scientific method in driving advances in this knowledge.  This first course o…

The physics of the Universe appears to be dominated by the effects of four fundamental forces: gravity, electromagnetism, and weak and strong nuclear forces.  These control how matter, energy, space, and time interact to produce our physical world.  All other forces, such as the force you exert in standing up, are ultimately derived from these fundamental forces. We have direct daily experience with two of these forces: gravity and electromagnetism.  Consider, for example, the everyday sight of a person sitting on a chair.  The force holding the person on the chair is gravitational, while that gravitational force is balanced by material forces that “push up” to keep the individual in place, and these forces are the direct result of electromagnetic forces on the nanoscale.  On a larger stage, gravity holds the celestial bodies in their orbits, while we see the Universe by the electromagnetic radiation (light, for example) with which it is filled.  The electromagnetic force also makes possible the a…

This course is designed to introduce you to the study of Calculus.  You will learn concrete applications of how calculus is used and, more importantly, why it works.  Calculus is not a new discipline; it has been around since the days of Archimedes.  However, Isaac Newton and Gottfried Leibniz, two 17th-century European mathematicians concurrently working on the same intellectual discovery hundreds of miles apart, were responsible for developing the field as we know it today.  This brings us to our first question, what is today's Calculus?  In its simplest terms, calculus is the study of functions, rates of change, and continuity.  While you may have cultivated a basic understanding of functions in previous math courses, in this course you will come to a more advanced understanding of their complexity, learning to take a closer look at their behaviors and nuances. In this course, we will address three major topics: limits, derivatives, and integrals, as well as study their respective foundations and a…
