Styrofoam makes a comeback in House cafeterias β CNN Political Ticker - CNN.com Blogs Washington (CNN) β An old standard is being reintroduced in cafeterias throughout the Capitol: Styrofoam cups. A little over a month after taking control of the House, Republicans have changed a pivotal element of Minority Leader Nancy Pelosi's "Green the Capitol" initiative. Since 2007, non-recyclable, Styrofoam cups were replaced with environmentally friendly biodegradable cups. The reappearance of Styrofoam cups is one move towards phasing out Pelosi's program, which brought climate-friendly vending machines and compact fluorescent light bulbs to the Capitol. The plan successfully reduced energy consumption by 23 percent and water consumption by 32 percent throughout Capitol buildings, according to an April 2010 report.
