As I understand it, Del Monte made a few mistakes. The first was related to COVID. Sales of canned goods spiked during COVID. They misinterpreted this as a permanent change and invested accordingly. Second, they did not find a way to comp

Or, less conspiratorially, it's because the volume of batteries that need recycling has been steadily growing.

That's a good point, so laws requiring bonds or insurance would also be needed. This could be an incentive towards at least limiting the worst case outcomes; if those are too large insurance may not be available.

The CO2 has to be scrubbed out. This is not necessarily all negative, since if the CO2 is injected underground for sequestration it makes biogas carbon negative.

Global fossil fuel infrastructure (which is much more than refineries) is estimated to be 1.34 billion tons of steel (and 10 million tons of copper). That's a bit less than 1 year of output of the world steel industry.

People have looked at microturbines to burn landfill gas. It's not something one could just put into a natural gas pipeline as it's about 1/2 CO2. Even in microturbines it requires cleanup because of cosmetics . In a land

The entire US jet fuel consumption could be more than adequately covered by fuel produced from the carbon in US waste streams.

There is lag created by sunk capital costs. Coal is still producing considerable electric power in the US, but the last time a new coal-fired power plant came online was more than a decade ago, and there are none under construction (althou

And also by isomerization and alkylation. Some of the processes involved in that involve rather heroic chemistry, using things like superacids to ionize hydrocarbons.

One place where gas is flared off is landfills. Methane is produced by anaerobic decay and must be burned to reduce its climate impact. One unfortunate consequence of this is bird injury, particularly raptors. They like to perch on the fl

There are large storage facilities for natural gas (underground, often in depleted gas fields or solution mined from salt formations) that buffer changes in consumption. These enable pipelines to operate efficiently even when demand is goi

The density of carbon in seawater is also higher much than it is in air. The relative concentration of bicarbonate in seawater is a few times lower than in air (as % by mass), but because water is nearly 1000x the density of air the true a

It's a common mistake to think that the syntax of Lisps are a problem. People solving the supposed problem then discover it wasn't something that needed to be solved.
