Due to the exhaustion and increased pressure regarding the environmental and political aspects of fossil fuels, the industrial focus has switched towards renewable energy resources. Lignocellulosic biowaste can come from several sources, such as industrial waste, agricultural waste, forestry waste, and bioenergy crops and processed into bioethanol via a biochemical pathway. Although much research has been done on the ethanol production from lignocellulosic biomass, the economic viability of a bioethanol plant in the Northern Netherlands is yet unknown, and therefore, examined. In this thesis, the feasibility study of a bioethanol plant treating sugar beet pulp, cow manure, and grass straw is conducted using the simulation software SuperPro Designer. Results show that it is not economically viable to treat the tested lignocellulosic biomass for the production of bioethanol, since all three original cases result in a negative net present value (NPV). An alternative would be to exclude the pretreatment step from the process. Although this results in a lower production of bioethanol per year, the plant treating sugar beet pulp (SBP) and grass straw (GS) becomes economically viable since the costs have significantly decreased.

Increasingly, entrepreneurial growth is discussed in relation to business sustainability and the wider questions of ‘growth’ – economic, green, or sustainable. This chapter will discuss the challenges and opportunities of teaching circular economy and Cradle to Cradle (C2C) models of sustainable production. The course applying circular economy theory to corporate case studies at the liberal arts college in The Netherlands will be discussed. Students were given the assignment to advise an existing company how to make a transition from a linear to circular economy model. https://doi.org/10.1108/978-1-78714-501-620171028 LinkedIn: https://www.linkedin.com/in/helenkopnina/
