Our economies and supply chains are mostly linear: extract, produce, use, dispose. What if we could master our transformations of matter in a circular fashion? How far could we drive our own supply chain efficiencies and sustainability? This discussion features two vignettes about technologies under development at PNNL that enable circular economies: hydrothermal liquefaction of sewage sludge and jet fuel from alcohol that comes from industrial waste gases. We begin by asking, “What challenges are we really trying to solve?” Then we’ll get to some fun, including pilot plants, industry partnerships, and even a commercial jet flight using fuel developed right here in the Pacific Northwest.
Pacific Northwest National Laboratory’s Community Science and Technology Seminar Series was launched to help the general public better understand and explore how science transforms our world.
