Concrete is one of those materials that is associated with green building (countertops, home construction, etc.), but it does take a large amount of energy to produce. However, its durability makes it attractive. The CB2 Element Coffee table is made of concrete, in an eco-friendly workshop...
The Element Coffee table is made from an aggregate of marble, granite, stone and natural fibers. Covered with a clear non-toxic wax finish, and handmade in an eco-friendly workshop powered without consumption of fossil fuels, it will truly last a lifetime.

The major impacts that people tend to associate with concrete are the use of cement, which is produced in an energy-intensive process, and the extraction of raw materials such as virgin aggregates.
However, the most energy-intensive component of concrete is portland cement which typically accounts for only about 10-15% of the total composition of concrete — the rest being water and aggregate.
So what do you think? Is this table a good purchase for a green home?

I would guess the environmental manufacturing process is more than offset by the cost of shipping a giant hunk of cement to your local CB2 or your home.
The table looks cool, but I don't think it's really sustainable. My understanding is that cement manufacturing is responsible for a relatively high percentage of greenhouse gas emissions. And I'd second what ChristopherB said...
hey
is concrete bio degradable?...apart from that I know for sure that cement industries are a ma
oops...the comment wasnt done yet!
cement industries are major resource gobblers...and effluent flushers into local rivers... :(...(as we see in any modern industry)
I love this table and drew up plans for any other crazy DIYers like us who want to try making it. This saves on that shipping issue too.
We used wood and concrete resurfacer:
