18 statements about Plastic, every show
Long-range aviation, shipping, and chemicals will remain hydrocarbon-based for decades
“Fast aircraft, big aircraft, long, long range aircraft, hydrocarbons. Probably long range shipping would stay that way. Like LNG, it's just so cheap. It's gonna stay that way for a long time. Paints are gonna stay hydrocarbon based. Chemicals, pesticides, herb…”
Kann: Most Plastics Emissions Come From Energy-Intensive Precursor Production
“To my understanding, the majority of the reason that plastic is, has a lot of embedded emissions is largely in the, is largely the energy consumption of the production of the precursors.”
Kann: Plastics are a smaller climate challenge because petroleum remains locked inside
“And I don't worry personally about the fact that plastics use petroleum inherently because that petroleum is locked up inside the plastic. It's not being emitted as CO two into the atmosphere generally. So I think that plastic is a climate Challenge, but I thi…”
Çubuk: Optimization of decades-old materials impedes commercialization of new discoveries
“If you think about plastics, we're still mostly using things that we discovered 70 years ago, 80 years ago, and we've gotten so good at, you know, manufacturing them, optimizing them, so now
For someone to come up and say, oh, I discovered a completely differe…”
Ballard: Replacing concrete with steel or plastic increases global carbon emissions
“If you replace concrete with anything, that number goes up. If you try to replace it with plastic, if you try to replace it with steel, think about where you use concrete.”
Slat: Only about 0.1% of annual plastic production reaches the oceans
“Looking at the latest data, so roughly four hundred million tons of plastic is being produced every year. And of that, it's only in the order of a few 100,000 tons that makes it to the ocean. So it's like zero upon one percent.”
Szaky: Switching from plastic to glass or aluminum is not inherently better
“No, I don't think so, because I think every material type has pros and cons. We're in a moment right now where we are I think rightly so, really projecting a lot of negative onto plastic because of microplastics, ocean plastic, all these things that are correc…”
Steyer: Americans Recycle Only 6% of Plastics as Consumption Explodes
“Even though we recycle only six percent of our plastics, the use of plastics is exploding.”
Atwood: Steel achieves an 80% to 90% global recycling rate
“Compared to plastics, where you're recycling maybe 10% of it, steel is like 80 or 90% recycled.”
Liedtke: Every piece of plastic ever created still exists on Earth
“What I like to term is, plastic is a forever material, which means there's not a piece of plastic that's ever been created that's not still with us today in some shape or form.”
Global Demand for Plastics Has Doubled Since the Year 2000
“Demand for plastics alone has already doubled since the beginning of this century, and shows no signs of slowing down.”
Dell: Fertilizer and Plastics Cause 80% of Chemical Sector Emissions
“Depending on exactly how you count it, fertilizer and plastic usually comes out to be like between 75 and 80% of all the GHGs from the whole sector.”
Dell: 60% of Chemical Fossil Inputs Become Products, Not Atmospheric Emissions
“We're only burning about 40% of it for energy. The other 60% of it, we're actually converting into the products themselves. So plastics are carbon-based chemicals. Where do we get all those carbon atoms? We get them from the fossil fuel inputs. And so this is …”
Dell: The Global Plastics Lifecycle Emits 1.7 Gigatons of CO2 Annually
“If you look at just the production phase of plastics around the world, we are talking about, you know, something in the neighborhood of Nine hundred million tons of CO₂ that's getting emitted, but if you look at the whole life cycle, estimates are more like 1.…”
Dell: Only 8% of All Historically Produced Plastic Has Been Recycled
“So we think that, like, over the whole history of the world, we've made about six and a half billion tons of plastic. About five billion of those tons are still around. And they are either in landfills or just, like, dispersed in the environment. They are plas…”
Dell: Plastic Prevents Organic Waste Decomposition in Landfills, Causing Methane Emissions
“What we actually do is we mix the plastic in with organic waste and put that in the landfill, and because there's all this plastic mixed in with the organic waste doesn't have any access to oxygen, and so it decomposes anaerobically and emits all of its carbon…”
