Abstract: Abstract Plastic production continues to increase each year, yet only 9% are successfully recycled. This has impacted natural habitats and ecosystems, due to an uncontrolled amount of waste. The food industry is a major contributor to plastic waste. To counter this problem, the demand for environmentally sustainable alternatives, i.e. bio-based plastics, in the pursuit of a circular economy is increasing. As such, this problem is interconnected and at the resource nexus of particularly, food, material, waste, and ecosystem. This systematic review provides an overview of different innovations regarding materials and additives for bio-based plastics for packaging in the food industry. The paper argues that a majority of materials for bio-based plastics originate from the food industry’s value chain and utilizing these resources is essential to reduce waste and to create more value, essentially addressing the problem with a focus on the resource nexus. Moreover, the importance of developing biodegradable and recyclable plastics to reduce the environmental impact of plastic waste is also highlighted, especially in the context of single-use food packaging. These findings and conclusions cumulated into a framework to differentiate the various materials and classify them regarding their biodegradability properties, origin (plant- or animal-based industry by-products and raw materials) and end-of-life scenarios. This contributes to the academic literature and practice by categorizing different kinds of materials, which might be labelled environmentally sustainable, particularly biodegradable, but which might not always be the case and critically discussing implications of this.
