I think you're saying that it's more valuable as concrete, right? That it can be made into something more expensive doesn't imply that it is also environmentally sound. In fact, those are almost always mutually exclusive goals. My question is about what will be used for roads, and whether acquiring that product will be more environmentally sound. I'm not immediately opposed to the technology. I'm just at least as skeptical as all scientists should be.

no, i am saying that the only real market for old concrete today is to replace some of the crushed stone used in making new concrete, for example for making roads, but that old concrete is in so little demand for this purpose that most of it ends up in the landfill it's possible i'm misunderstanding, but you seem to be asking whether making crushed stone is more or less environmentally damaging than recycling old concrete. the answer is that neither of them results in significant environmental damage in itself, but trucking them to construction sites does also can you elucidate which goals you meant to say were usually mutually exclusive? it isn't clear from context also, i asked two questions in my previous comment that you haven't answered: are they offering you money for your old concrete? how much are they paying?

  I meant that we typically need to choose between two goals. Profit and environmentalism. They are offering money. As for how much, I imagine it depends on the area. All things gravel and stone are expensive at the moment. People are getting caught stealing sand, that's the world we're in today.

    i see, thanks! it sounds like you haven't attempted to take them up on the offer it's not true that gravel, crushed stone, and sand are expensive, by most definitions of 'expensive'. they cost pennies per kilogram. yes, that's enough for people to make a profit from stealing
