"Partnering to make recycling strong through economic and environmentally sound solutions."
The Northeast Resource Recovery Association (NRRA) is the oldest and largest cooperative-model recycling nonprofit in the United States. NRRA partners with over 450 municipalities, businesses, and individuals throughout New England to make recycling strong through economic and environmentally sound solutions. In particular, NRRA supports many small, rural communities in New Hampshire, Vermont, and Massachusetts. NRRA is one of only a handful of nonprofits in the country that enables communities to manage their own recycling programs by connecting them with end markets for recyclables. Founded in 1981, NRRA has a deep expertise in the recycling markets, and in partnership with our members, we share that information through education and technical assistance.
Yes, but it would not be as strong if you use PGA, which is shown in this video, where pieces are still chunks of glass, opposed to grinding it into powder. For reference: www.concretedecor.net/departments/concrete-placing/waste-glass-in-concrete-has-advantages-and-disadvantages/ "The strength of concrete containing glass powder as a cement replacement material is approximately equal to that of concrete containing only portland cement. However, its durability properties outperform that of conventional concrete. The strength of concrete containing glass aggregates is 10%-20% less than that of concrete containing mineral aggregates. This reduction in mechanical properties is due to the lower strength of aggregates as well as less bonding between the glass aggregates and the paste compared to the mineral aggregates."
This is how they got that overpass opened in two weeks, the one in Philly. Piled up PGA, paved over it. Conventional sand and gravel quarrying is hugely destructive of river bottoms.
I remember some years back it was mixed with some asphalt applications. It should be the STANDARD. We should be using more glass vessels and get rid of the DAMN plastic. Oh yeah, glass costs more. What is the cost of filling the oceans with the DAMN plastic?
no it can't cement or concrete needs moisture to bond materials together and this material does not absorb water it actually repels it so it would be good for a base but will not work in the actual mix

It's a no brainer once crushed and screened it good stable aggregate for concrete and asphalt many studies have shown this but I would be nice to recycle it back to glass products instead but then you have to separate by color to do so extra step but is done elsewhere
Not Issue of finding need, more like Building processing machines, I've looked, Only Excuses, 'Not worth' ... conspiracy.^ 5:13 What!? WHY HIDE "PGA"? Silly to keep secret; As your words seem to say, Others rather throw their Glass away. ^ Here in Florida, Glass [was] ON Recycling list, ... until it wasn't. *Lack of Roads, while population Grows.* NOT Smart.

There’s a product called glavel being produced in Vermont that is thermally expanded recycled glass that can be used in place of gravel in concrete and gas insulation as well. But it’s more expensive to produce than this crushed glass product.
pro internet tip, type any idea you have with the word scholar at the end to get real information on the subject. crushed glass aggregate scholar, I've read many of the glass concrete articles its good stuff
Sad thing our government would rather have us use dangerous plastic containers with think its called BPA'S cancer causing crap that heard most European counties have banned. Guess some scum bag Senators are still getting nice kick backs from p!astic companies. Thought they were going to start a good fund me millionaire site for poor POS rich Senators that had kick backs & stock tips lowered during pandemic.
Many places do, but only "clean glass" can be turned into new bottles and jars (or fiberglass!) They cannot have any contaminants like ceramics, pyrex, mirrors, etc. - things that folks think of as "glass" but have a different chemical makeup (and would thus make a subpar new product...and no one wants their glass bottle to break!)
you do realize that years in the future some poor archeologist or geo is going to come across this stuff and wonder what the heck it is because all the other concrete or bituman will be gone and just the strata of crushed glass which never decomposes. would be so funny to watch,them pondering and arguing over what it is and why and how. haha.
Reuse of glass cullet saves very little energy. Unlike aluminum where there is huge electrical energy needed to strip oxygen off alumina, glass only needs melting and temperature hold to allow bubbles to rise.
Every developed country either reuses glass - this is the best Form of recycling or it is collected separatedly and then recycled to new glass bottles since it is reusable basically in an infinite way. This 1960s variant of collecting the trash together with the glass and separate it later to downcycle it is the american "we are stuck in the last century" way where no one thinks about environment or saving energy or even efficient processes in the first place. But what can you expect from a country using weird legacy units instead of commonly used units like meters and kilos, discovering insolation on houses as a next big thing and having overhead power lines depite having 120 years of time to bury these lines and then complaining about power outages after every hurricane...
It would work. The problem is that unlike local DOT, who can get it from their own local recycler, a railroad company would have to source it just like gravel. And they already have contracts for the gravel.
In the UK 1975 l had 8 trucks collecting and moving cullet, the price was 48 pounds sterling per ton for mixed, 60 for clear, as soon as recycling came in big time the price was 10 per cent, paper and cardboard was the same. Recycling put many out of work, l sold my trucks and put all out of work.
Fun fact - it takes more energy to recycle glass into new glass bottles than to make new ones from sand. We are currently,stupidly producing so much concrete worldwide that we are literally running out of usable 'sharp' sand for construction so this PGA is not just a nice idea,I'd argue that it is an essential low-impact building material whose use should be adopted worldwide.
Sometimes here in Pennsylvania when the sun hits the road made of macadam just right you can see what resembles glitter and I've always assumed that crushed glass was added to the mix. Is that true, and what are the benefits of using it that way?
The "glitter" is a substance called MICA that is in some gravel in the mix design. It is not harmful to the hot mix, just sometimes annoying under certain conditions.
I had an asphalt salesman in my National Guard unit in NY and he had experience using PGA. They stopped using it due to non-stop lawsuits. They would get injured people showing to court with fake pictures of half bottles tarred into a street somewhere. The company won every suit but even free PGA didn't cover the cost. Legislative protection is required for the product to ever become used widely.
This seems just made up. This stuff in no way resembles any glass container. "Legislative protection is required for the product to ever become used widely."- this also seems like an oddly specific opinion for a random youtube comment.
