Cement - A Dirty Business - KQED QUEST |
Here’s an industry you don’t often think
about: cement. And yet, if you live in
California, you use about 4,000 pounds
of it every year. Much of that cement
comes from one of two kilns here in the
Bay Area. Cement kilns don’t
traditionally get a lot of attention,
but times are changing.
Find out more on the KQED-FM Radio piece on KQED QUEST and comment on the QUEST Science Blog.
