These drink chillers/coasters might not be particularly striking, but I'm putting them up because they're an example of a company seeking to do something we all should: Turn scraps into something useful.
Granite slabs are a popular material for countertops, but as with all natural materials that are machined into a finished product, they produce waste. A company called Sea Stones turns those small, otherwise worthless cut-offs into these recessed coasters, which come shod in recycled rubber to protect your tabletops.
The company also produces granite napkin rings that are apparently manufactured using a hole saw type of device rather than a boring bit, as they're able to save the plug from the center of the hole. Those plugs, in turn, then become the drink chillers sold along with the coasters. "They have plenty of thermal mass to hold the cold long enough for leisurely sipping," the company explains.
All in all, it's a good attempt by a company to reduce waste by marrying available resources with customer need. The question of whether they have bridged that gap adequately and tastefully, of course, will be up to consumers like you all to decide.
