Could be a heckuva lot worse! I don't know if it connects to the San Rafael Canal, but my gramps used to catch steelhead in the San Anselmo Creek when he was a kid in late 30's just a short walk from his house.

We did this in the 70s when we were 8-10 years old. Didn't know it was WAY wrong until freshman year when we lugged a holdover out of the creek with a treble hook and paraded in to the Woodacre store. The owner was nice enough to inform us of federal fish and game rules. Oops.

glass beer bottles are recycled into glass products

Definitely not.

I recycle my glass, but no recycled glass will ever be glass again. COE, or coefficient of expansion, is what defines types of glass. I use 33coe, borosilicate. Meaning it expands .000033mm for every 1 degree Celsius increase, same way metal expands before it’s liquid hot (don’t quote me on the amount of 0’s) It’s a blend of mostly silica and boric oxide among other things. High melting point and low COE. Most glass out there is “soft glass”, or soda lime, made of silica, sodium carbonate, and calcium oxide, with a COE of 90-100+. Lower melting point, longer working window. Glass with a lower COE expands and contracts less with changes in temperature, which is why people like Pyrex dishes, particularly the old ones, as they were borosilicate with a COE of 33 where as these days the name has been sold and Pyrex dishes are no longer boro, they have a COE closer to 90 and they can’t take sudden changes in temp like from oven to cold counter or whatever without cracking. Same reason any lab equipment is made of borosilicate or quartz. Long story short, you can’t blend unknown COE’s and make usable glass so any glass you recycle will end up as sand and or components for asphalt/concrete kinda stuff.

Actually, glass beer bottles are recycled into glass products. I've seen it down at Orizaba. I did a seismic risk evaluation of the plant, and of the neighboring Cuauhtemoc Moctezuma brewery (home of Dos Eques.

Nice photos all.... and yes. Looks cold in Maine. :teeth

Here is a work photo.
Working on a vocational school and we meet in the empty building.
Card board boxes for a table.

Chairs are way far apart. Giant 30’ diameter circle.
But at some point we have to look at plans.

It is going to be a sweet facility. Fun project.
