Plastic technologies appear at least directly once more, via 3D printing at #8, a 7 position drop from the list for 2019 (the synonymous term additive manufacturing yields more than 1,400 articles at PlasticsToday).
You can also find plastics “hidden” among the remaining technologies where plastics are used or are applicable; for example, that now includes Blockchain, which landed at #15 (see Blockchain technology applied to plastics traceability and sustainability, published October 2019), and 2D materials, which appears at #18. Wikipedia defines two-dimensional materials, which are sometimes referred to as single-layer materials, as "crystalline materials consisting of a single layer of atoms. These materials have found use in applications such as photovoltaics, semiconductors, electrodes and water purification.”
You can find 640 articles on 2D materials at PlasticsToday.
Lastly, I was curious why some technologies that appear smoking hot from this editor’s chair were omitted, for example Robotics/Collaborative Robotics. It seems that growing market and any others fell off the list only because it had either “went mainstream” (which was the case here), changed form (as with wearable technology) or simply fell in relative terms versus hotter tech (for example, AR/VR).
