Resumen de Brewing benefits?: Alcohol, hangovers and better bricks
There's more to brewing than beer. A by-product of the process could be about to give an upgrade to a workhorse building material--red clay bricks. By blending in the grains left over from making beer, the bricks can be more environmentally friendly and better insulators. Bricks are often impregnated with polystyrene as a way to enhance their heat-trapping abilities. This is appealing, because the bricks remain strong, and they can be built into energy-efficient buildings, says Eduardo Ferraz of the Polytechnic Institute of Tomar in Portugal.
