This book exposes the illegal management of waste oils and bunker fuel and how they harm our health and the environment, while highlighting efforts made in the Netherlands to combat these crimes. Wherever you are right now, there’s a good chance that an object in your vicinity is connected to the stories told in this book. The phone in your pocket, the chair you’re sitting on, or the shirt you’re wearing – they likely travelled to you on a large container ship, which burned bunker fuel. Alternatively, petroleum-based substances were likely used in their production, which involved the generation of waste oils. We rarely talk about waste oils or bunker fuel, yet they are essential to our modern existence. They are also dangerously intertwined: waste oils are systematically blended into bunker fuel at the cost of our health and that of our planet. These activities violate international and EU law. In the Netherlands, they are criminal offences. Also in the Netherlands, unique efforts have been made to fight these crimes. This book draws on never-before used data on both crimes and enforcement to shed light on this murky world. Whether you are professionally or privately engaged in contrasting corporate crime or environ mental harm, this book can enhance your perspective and toolset. 1 Introduction; 2 Methods & Methodology; 3 The Waste-Product Nexus - Exploring the Physical, Economic and Regulatory Features of Two Overlapping Industries; 4 Deconstructing Two Criminal Events Using Crime Script Analysis; 5 A Crime-Facilitative System at the Intersection of Two Symbiotic Industries; 6 Andante: Exploring an Example of Capable Guardianship; 7 Conclusions; Annex I – Additional Materials; Annex II – Field Work; Annex III – Details on Waste Oils and Bunker Fuel; Bibliography
