⚡ Carbon & Energy

Podcast: Hot Buttons
Episode: “Unpacking Fashion’s Complicated Impact on the Planet”
Hosts: Christina Binkley, Rachel Kibbe & Shilla Kim-Parker
Category: ☁️ Carbon Reduction | Impact of Fashion
Apple | Spotify | Google | 🕰️ 58 min | 🗓️ 06/16/2022

[11:41] CB: “What is fashion's actual impact on the environment? […] Can we measure it? […] We hear a lot of sweeping stats in this industry. Some of my favorites are: fashion accounts for 10% of global emissions, it creates 20% of global wastewater. The one we've all used a million times for reasons we probably can't even explain is that fashion is the second biggest polluter after the oil industry. We know the environmental impact of fashion is vast. […] We can see the growing waste problem of ultra fast fashion and photos and documentaries. But I wonder if it's been properly quantified? In fact, it turns out, nope, it has not.

Episode: “Making Sense of Solar Engineering”
Host: Shayle Kann
Guest: Dan Visioni | Climate Researcher
Category: ☁️ Carbon Reduction | Solar Engineering
Apple | Spotify | Google | 🕰️ 45 min | 🗓️ 06/16/2022

Selected Quote:

[7:54] DV: “[Solar geoengineering] is the idea that we can intervene on the solar radiation that is incoming on the planet. […] The solar radiation comes in, it warms the planet, the planet then tries to be in equilibrium with the rest of the universe. And so it radiates back part of the energy that it absorbs from the sun. But the high amount of CO2 means that too much of the radiation that is supposed to escape stays in the system and so the planet warms more. So the idea is that the only way we can fix that is by reducing the amount of CO2 that is in the atmosphere. […] [To scale] carbon dioxide removal […] is going to take time. So the idea is, is there something we can do at a much faster scale? So can we intervene in the solar radiation that is incoming […] so that the planet warms up a bit less to begin with? And so we don't experience the effects of global warming too much.

Podcast: The Carbon Copy
Episode: “The Battery Recycling Boom”
Host: Stephen Lacey
Guest: Julian Spector | Senior Reporter | Canary Media
Category: ⚡ Energy | Battery Recycling
Apple | Spotify | Google | 🕰️ 21 min | 🗓️ 06/15/2022

Selected Quote:

[1:36] SL: “Lithium prices have risen five fold since April of last year. Nickel is also a particular concern because Russia supplies 10% of the world's nickel and that's another key component in lithium ion batteries. […] So battery prices are going up, when they should be going down. Definitely not a helpful trend for a technology so crucial for balancing renewables on the grid or electrifying vehicles. But this supply mess could actually be boosting a positive trend in the space: battery recycling. Battery recycling was once seen as an environmental solution, but suddenly it's turned into an economic and national security imperative.”

Podcast: Climate 21
Episode: “Reducing the Carbon Footprint of Lithium Ion Batteries”
Host: Tom Raftery
Guest: John Cooley | Chief of Products | Nanoramic Laboratories
Category: ☁️ Carbon Reduction | Lithium Ion Batteries
Apple | Spotify | Google | 🕰️ 39 min | 🗓️ 06/14/2022

Selected Quote:

[11:29] “The overall societal pressure and goal is to reduce CO2 emissions at large, but you're using quite a lot of energy in the battery manufacturing process itself. And that releases CO2 emissions on its own. And so, one of the advantages of Neocarbonix is that we eliminate this conventional binder from the electrodes. We eliminate therefore, the requirement for this particular special solvent that's used to dissolve that binder. And we can use things that are much easier to evaporate like water, or alcohol based solvents, or other solvents. And when we do that, we reduce the energy consumption in […] the entire battery manufacturing process […] by 25%. […] That's about a half a million metric tons of carbon dioxide emissions per year that we've removed from the battery manufacturing process.”

We started in April of 2021 […] and are pushing forward in making sure that we can have more electric motorcycles on the road.”

💧 Food & Water

Podcast: Climavores
Episode: “Why Eating for Climate is so Complicated”
Hosts: Tamar Haspel & Mike Grunwald
Category: 🍏 Sustainable Food | Eating for Climate
Apple | Spotify | Google | 🕰️ 28 min | 🗓️ 06/21/2022

Selected Quote:

[7:45] MG: “We already generate a third of all our greenhouse gas emissions from our food system, which I think a lot of people don't realize. A quarter of our emissions come from agriculture. […] Right now, if you want to think of the Earth, the built environment that we all hang out on is like 1% of it and the rest of it is agriculture and nature. And the basic problem is that now we're having too much agriculture and not enough nature. Deforestation is a 10th of our emissions and that is almost entirely driven by agriculture moving into forests. And as the population grows, and we need more food to feed the world, that's going to become an even bigger problem. So farmers are going to have to grow the calorie equivalent of 800 Olive Garden breadsticks for every human being alive every year. That's a lot of carbs.”

Selected Quote:

[29:06] “I'm a big fan of riding the coattails of the energy industry. […] What happens in our two sectors is inextricable. And a lot of the things that are going to happen in the energy sector, clean energy initiatives, renewable energy and so forth. We're going to be tapping into that, too. […] These aren't silos. […] There's a big Venn diagram in my mind, and the three partners in it are water, energy and food. And generally, what benefits one can benefit the other.”

Podcast: (don't) Waste Water!
Episode: “How to Save over 1 Million Tons of CO2 every Year with Thermal Hydrolysis”
Host: Antoine Walter
Guest: Eirik Fadnes | CEO | Cambi Group
Category: 🤖 Technology | Thermal Hydrolysis
Apple | Spotify | Google | 🕰️ 37 min | 🗓️ 06/22/2022

Selected Quote:

[12:28] “Essentially [thermal hydrolysis] is a giant pressure cooker. So sewage sludge from the wastewater treatment plant is first dewatered, […] it is pre-heated using recycled steam. And from the preheater the warm sludge is processed through a pressure vessel, where it’s mixed with steam until you get a temperature of 160 degrees […]. And at the end of the cycle you have a certain pressure drop down to atmospheric pressure which disintegrates the cells and reducing the sludge viscosity and making the feedstock very suitable for anaerobic digestion. So you get the increased biogas production up to 40% and you get half the volume of the biosolids compared to conventional methods.
