In case you didn’t know, apparently there is a shortage of sand in the world. Since sand is used in a variety of industries, ranging from construction where it is used in mortar, plaster, concrete, asphalt, as well as being used in the pharmaceutical industry, safe to say that it is a very important resource.
This is why over in New Zealand, a report from AdWeek (via Geek) has revealed that a company called DB Breweries has launched an effort to help with the sand shortage. How, you ask? By asking customers to drink more beer, and to put their empty beer bottles through specially-built machines, where those bottles will be crushed into a sand substitute.
