The idea of a conversation about the most environmentally friendly way of igniting coal is quite amusing.

Charcoal is pyrolized biomass, not fossil fuel, which means it's approximately carbon-neutral. The problems with it are more associated with deforestation.

Isn't there some sort of energy input in process? I wonder where that usually comes from in industrial production.

Conventional consumer-grade charcoal briquettes used for backyard BBQ typically have some amount of coal in them.

No regular brand of charcoal contains coal. Please link just one brand that does and I’ll withdraw my complaint but I’ve worked in the industry and very much doubt this.

"Charcoal" literally means "coal made by charring [implicitly: wood]". I assume you (and probably rootusrootus) mean "No regular brand of charcoal contains [fossil] coal." (eg, lignite, bitumite, or anthracite).

(I don't know what they're on about either; presumably for sufficiently historical values of "conventional" barbecue coal was supplied from the same mines as train / steam engine / home heating coal, but that isn't much of a thing anymore.)

Anthracite coal, 15-40%

That’s from a major brand.

I was surprised to learn this. But I’ve always been suspicious of charcoal briquettes — lump charcoal is much nicer. (And one should IMO always use a chimney starter or similar device in order to get them properly lit as quickly as possible and with as little other junk added and hopefully as little emissions as possible.)

Do you have a source for that?

Sure. Anthracite coal, 15-40%.

Anyone using briquettes should switch to lump charcoal.

You're being downvoted, but another comment in this thread proves you're right:

I'm as surprised as anyone. I had no idea.

Still would be better to keep the carbon solid than released into the atmosphere, no?

In that case you would not need to produce charcoal in the first place

Only way that realistically happens is if you bury it deep underground. Charcoal above the surface is part of the carbon cycle.

Charcoal is resistant to the natural decomposition that normally turns wood back into CO2. Therefore if you char wood then bury that charcoal, you don't need to go deep underground to sequester the carbon. Burying charcoal in the topsoil can sequester that carbon for thousands of years or more.

When burning things not 100% fully you produce carbon black, which has a greater greenhouse effect than if you would release carbon as CO2. Further harvesting wood leads to younger forests, which store less carbon than old growth forests. A better use-case than burning is using it for durable goods like in construction, which binds the carbon for much longer.

p.s. I'm not telling anyone to stop doing bbq, just to stop lying to themselves about the negative effects it has

Carbon black, or black carbon? Black carbon only stays in the atmosphere for a few weeks, and while I can't find data on carbon black it presumably falls to earth pretty quickly too, which makes me think you're comparing instantaneous rather than lifetime greenhouse effect.

Deforestation and release of its bound carbon which will take decades for trees to recapture, manufacturing and transport, impure combustion (which may also include non-carbon pollutants), yadda yadda...

How does that become approximately carbon neutral? And that's before we look at the safety datasheets shared in the thread that indicate 15-40% anthracite/black coal as ingredient in (some?) charcoal briquettes.

Charcoal and coal are quite different.

At the same time, the most common form of 'charcoal' that an average person will use in their BBQ is made from both charcoal and coal, as well as other things.

standard charcoal briquettes contain coal?

i’m amazed to hear that.

(I use lump charcoal myself which seems to give to food a better smoke flavor)

They do often contain coal. Briquettes are weird. For smoking, you really want to be using wood (or charcoal and wood); charcoal has most of the volatiles burned off already, in principle leaving behind only carbon, so it isn't great for smoking things.

No regular brand of charcoal contains coal.

Please link just one brand that does and I’ll withdraw my complaint but I’ve worked in the industry and very much doubt this.

> "Kingsford Charcoal is made from charred soft and hardwoods such as pine, spruce, hickory, oak and others depending on which regional manufacturing plant it comes from. That char is then mixed with ground coal and other ingredients to make a charcoal briquette. As of January 2016, Kingsford Charcoal contains the following ingredients:[7][8]"

https://en.wikipedia.org/wiki/Kingsford_%28charcoal%29#Manuf...

If this isn't true, they need to fire their entire PR team.

This MDS says it contains anthracite: https://www.thecloroxcompany.com/wp-content/uploads/kingsfor...

Wow. Son of a gun you're right. Here's more info on why coal dust turns out to make an ideal binder for charcoal briquettes:

https://mineralmilling.com/coal-dust-a-superior-choice-as-a-...

I had no idea. Key quote:

"Research and patent literature show that when charcoal briquettes are produced using an organic binder such as anthracite, the binder is present in quantities of between approximately 2 and 8% by weight."

And "coal, anthracite" is clearly listed as the third most common ingredient in the safety sheet for Kingsford Charcoal Briquettes, after charcoal and ashes.

i should clarify i’m not smoking the meats, i’m just grilling. But I can definitely taste the difference between charcoal and briquettes.

I guess for real smoking i’ll have to find wood.

> I can definitely taste the difference between charcoal and briquettes

Yes I agree. I either use lump charcoal, or hardwood that I let burn down to embers. Briquettes impart an unpleasant flavor.

You’ve repeated this a few times, but I clicked on several charcoal options on Home Depot’s website, and they claimed to be made entirely of “100% natural hardwood”. Maybe some cheaper ones have added coal?

Take Kingsford, for example, probably the single most popular brand of briquettes at Home Depot. It does not say 100% natural hardwood, it says 100% natural ingredients, including wood. Coal is natural. And 15-40% of Kingsford briquettes [0].
