Germany of course. Although we do have the sweepers run once/week on all the cycle paths as well.

We avoid smashed bottles on the cycle paths by giving the local drunks nice benches next to the river ... that way they can just through their bottles in the river instead.

I'd suggest some self sealing tubes like Michlins or alternatively adding Stans Notubes or Zefal latex foam to a standard tube. You could further up that for effectiveness by going to tires with flat protection built in IN ADDITION to the tube protection mentioned.

If glass gets past that - chances are you'll need a new tire and not just a new tube. Otherwise - you should be good for the season. One cautionary note - anti-flat liquids aren't recommended for winter use. They'll be too sluggish to spread effectively and just upset the balance of the wheel.

Get some armadillo tyres, and don't worry about it

This is excellent advice!

Oh great an environmental whack job that thinks broken glass everywhere including in the ocean is better than plastic bottles that can be picked back up.

What do you think much of your computer is made of, your car, your phone, parts in your bicycle?

actually, I'm surprised that you don't know this ...

most plastic in the ocean doesn't get picked-up, it get's ground up and has formed essentially a moving island

https://en.wikipedia.org/wiki/Great_P..._Garbage_Patch

due to this, in many way glass is much better.

I am well aware of the garbage patch. And no, glass is not much better.

So you also have no plastic in your computer, car, phone, bicycle, etc.?

Actually, the garbage patch is almost ALL plastic, so glass is much, much better because it "breaks down" and/or is shattered and therefore doesn't contribute to the garbage patch. To be honest, you sound somewhat environmentally ignorant for a Hawaiian, which is contrary to most Hawaiians that I know.

Personally, I avoid consumable plastics as much as possible. Almost all drinks that I purchase are in glass (beer/water/wines/some juices ... which is very common in Germany), and all of my non-glass stuff is Tetra Pak ...

https://en.wikipedia.org/wiki/Tetra_Pak

which means that I can store my milk/some juices at room temperature for months until I open it. Given that it's usually purchased in 1L increments, I only need to refrigerate the opened package for a day or so until it's consumed, so I also require a smaller fridge, which reduces my energy consumption and environmental footprint.

Glass does not break down. Ultra violet light breaks plastic down. So much for who has displayed ignorance in this thread.

The world is bigger than the garbage patch.

You know that you're talking with a chemist right? Of course it breaks down, which is exactly the problem, because it enters the food chain and accumulates in fish that swim in the upper water column.

Glass doesn't do that, although it does mechanically break down which is my point (rather than the biomolecular decomposition), and even if it did accumulate in fish that swim in a particular water column, the glass wouldn't contain the chemicals that resides in the "plastics" that are present.

But we're far from the original topic.

Why the hostility, rudeness and name calling? Just because I happen to believe there is a big difference between single-use plastics and those used in more durable goods? If you disagree with me, okay, but why the disparaging comments?

They had a trash fill at Fort Bragg, CA, that is now a tourist attraction https://www.fortbragg.com/explore/glass-beach/
Just buy aluminum. I've seen people stop in a busy intersection and get out to pickup a can...

Hi Slim! Welcome to the Real World™. It's not different than your 200k-mile steel-framed bike!

I would think that we are all capable of exchanging ideas, without insulting one another. We must learn to demonstrate mutual respect. Nobody is better than another here ...

BTW

Fish don't eat glass or rocks. However, they can't avoid certain plastics that have degraded and entered into their food chain (our food chain). The future detrimental consequences will prove to be enormous, I'm sure.

Also, glass will degrade in time. A very very very long time. Buried plastics won't degrade without the assistance of UV radiation.

Correction:

Over 200k-mile-steel-framed-bike...That's 200k+

Thank you very much!

That's my point.

Just deal with the glass breakage, or make the deposit so high that drunks don't smash them (here it's up to 7 dollars for a case of glass beer bottles) which is half the cost of a new case. I never see smashed glass bottle ... I do see smashed glass from a car window that's been stolen, but that's a different social issue.

We've (Humans) had plenty of issue with accumulation of toxins in fish


And it's more of a social acceptability issue as shown here (how/why glass i recycled in Germany ... vid is in English) also good for the beer lovers out there

no evidence (no pics!) =

Whatcha want? A picture of my odometer!

of a 30-year old frame.

When I was a kid growing up in California, we used to pick up pieces of multicolored glass that had washed up on the beach. It no longer had its sharp edges and was really quite beautiful. Not that I recommend disposing of your beverage bottles of any type in the ocean...

Oh, who stated the rude comments. That is right you did.

Two interesting videos.

Regarding the second one, the Germans are forging ahead in so many ways, whether it be something as simple and grounded in common sense as reusing bottles or investing in their mass transit infrastructure, they exude the kind of self-confidence that the United States was once known for. Germany is now the undisputed leader in the new energy economy. Twenty-seven percent of their electricity now comes from renewable sources, and they are determined to keep moving forward, some saying they can reach one hundred percent by 2030. That kind of "can do" spirit reminds me of the U.S. back in the 60's, but now, sadly, we are bogged down in a ridiculous dispute about whether global climate change is a hoax, and any attempt to move forward is fought tooth and nail by a backward group of science deniers who seem to have no vision at all of the future.

That was a supposition, not a rude comment.

Now, if possible, I'd like to get back to discussing the issues. I trust you'll be able to do that in a civilized manner.

Failures to view the big picture.

Glass manufacturing:
Two types of air emissions are generated: those from the combustion of fuel for operating the glass-melting furnaces, and fine particulates from the vaporization and recrystallization of materials in the melt. The main emissions are sulfur oxides (SOx), nitrogen oxides (NOx), and particulates, which can contain heavy metals such as arsenic and lead. Particulates from lead crystal manufacture can have a lead content of 20–60% and an arsenic content of 0.5–2%. Certain specialty glasses can produce releases of hydrogen chloride (HCl), hydrogen fluoride (HF), arsenic, boron, and lead from raw materials. Container, pressing, and blowing operations produce a periodic mist when the hot gob comes into contact with the release agent used on the molds. Some releases of particulates will take place in tapping. Lead glass manufacture may result in lead emissions of about 2–5 kg/t. In all cases, the concentration of heavy metals and other pollutants in the raw flue gas mainly depends on the type of fuel used, the composition of the feed material, and the portion of recycled glass. High input of sulfates or potassium nitrate may increase emissions of sulfur dioxide and nitrogen oxides, respectively. Where nitrate is used, more than two thirds of the introduced nitrogen may be emitted as nitrogen oxides. The use of heavy metals as coloring or decoloring agents will increase emissions of these metals.
