Maybe save a few pennies on overhead, I guess?

Anyhow, I'm done talking about education, but I will leave you with one final thought.

An Oklahoma grad, a Penn State grad, and a Michigan grad were walking down the road one day when they came across a comatose woman lying in the street, completely naked. They called for help, and did their best to cover the woman up. The OU and PSU guys took off their hats and covered her breasts, and the UM guy took off his hat and covered her crotch. When the EMTs arrived, they began to tend to her. AN EMT handed the OU and the PSU guys their hat back, but when he took off the UM hat he put it back, lifted it carefully and peered underneath. He did this twice. Angry, the OU guy asked the EMT what he thought he was doing. The EMT replied, "It's weird. I'm used to seeing an A$$hole under one of these things."

Not sure whether to take this as a compliment or an insult.....

http://productiongap.org/

Governments are planning to produce about 50% more fossil fuels in 2030 than would be consistent with limiting warming to 2°C and 120% more than would be consistent with limiting warming to 1.5°C.

Oil and gas are also on track to exceed carbon budgets, as countries continue to invest in fossil fuel infrastructure that “locks in” oil and gas use. The effects of this lock-in widen the production gap over time, until countries are producing 43% (36 million barrels per day) more oil and 47% (1,800 billion cubic meters) more gas by 2040 than would be consistent with a 2°C pathway.

I'll be interested to see how that report has changed next year when it accounts for the consequences of the pandemic.

In other news, I'll be following this technology. If it gets commercialized, it would go a long way towards making hydrogen economic while also helping fix our waste problems.

Are you thinking that the pandemic will have a larger effect than just a temporary drop in coal/oil/gas emissions?

It's impossible to predict to what extent, but I think it will have some negative affect beyond what has been projected in previous years.

I think it'll certainly reduce air travel for an extended period of time for business and personal travel, alike. I don't know what impact it will have on vehicle travel, particularly for domestic summer vacations, though I think it has accelerated the acceptance of remote working which reduces commuting (and resulting traffic) long-term, even accounting for the reduced usage of mass transit, especially in cities with strong transit systems (DC, NYC, Boston, Chicago, Bay Area, etc.). It should accelerate the decline of coal generation since that's the marginal generation source (though this won't happen as quickly in states outside of the ISO/RTOs, especially in the Southeast).

If more manufacturing becomes domesticated (or even if trade becomes more common with Canada & Mexico as opposed to China and the rest of Asia) then that reduces shipping, as well, which I'd argue more than offsets the increased industrial emissions.

Time will tell, though....

Good points.
And, yes, it will.

How ever I want to, not how I'm told to.

Your thinking is the problem.

Just because one way of doing things was railroaded through you and your cohort, and you all suffered through it together, doesn't mean it's the one right way for all.

Yes, you will be told multiple ways of doing something, be expected to show at least a rudimentary knowledge of each of those ways, SO THAT YOU CAN MOVE FORWARD WITH THE ONE THAT WORKS BEST FOR YOU.

I never took notes in school. Ever.

Never paid attention either. Just had to show up.

I graduated high school in 3 years. I couldn't stand for another year of "stupid".

A big problem with municipal solid waste is how much water is in it, on average. A second problem is chlorine and heavy metals.

It would be interesting to see an energy balance on hitting it with plasma torches and getting out hydrogen and CO. Folks who incinerate MSW usually have to add natural gas to it to get the fire hot enough to drive off the water.

Anyone know the current stats on recycling? When I was in college, the professor I had for an environmental course said that only about 20 percent of what went in the bin was actually recycled.

Are wine bottles recyclable?

I've heard yes, I've heard no.

What I saw years and years ago was that the nonsource separated "recycled" trash is about 5% recycled based on volume. It comes out on a conveyor moving pretty fast and some folks standing by the belt grab what they can, focused on Al cans. A few try and grab some plastic that is clear to them, they miss most of it. A milk jug with the cap on goes by because the jug part and the cap are different plastic types. The rest gets buried.

I don't imagine it has changed much, it really is a "feel good" kind of thing.

What has changed, and then stopped, if the lines would take out ALL plastic types and send bales to Asia. China recently said "No more". Those empty container ships would carry our crap back to Asia and they were overwhelmed, as they would need to separate the plastic into different types for recycling.

The properties of PE (most plastic) and PP and PET (Coke bottles) etc. are very different and to be properly recycled they need to be separated. Otherwise you get much, and the different types tend to separate or cause physical defects in the new melt processed materials.

Basically, these bales of non-source separated plastic has negative value.

I was once tasked with making a certain kind of polymer "compostable". I've written about that disaster before, it was interesting work at least.

Composting was supposed to "save us", but it was clearly a scam and wasn't going to happen for MSW.

According to the EPA, 9.1% of plastic material generated in the U.S. Municipal Solid Waste (MSW) stream was recycled in 2015. Another 15.5% was combusted for energy, while 75.4% was sent to landfills.
Plastic recycling results in significant energy savings compared with the production of new plastics using virgin material.
PlasticsEurope reports that 7.7 million tons of plastics were recycled globally in 2014 That includes more than 3.5 million tons of post-industrial and post-consumer plastic scrap that were recycled in the United States, according to ISRI estimates.
According to the EPA, about 30% of recyclable plastic bottles and jars were actually recycled in 2015.
