It's a pity that this recycling iniative seems to have been overturned because of politics!

Polystyrene makes comeback in US Congress building after Republicans reverse green initiatives brought in by Democrats

A bit like the Republican party, they are white, seemingly indestructible and bad for the environment. But after an absence of four years, foam plastic coffee cups have made a comeback in the basement coffee shop of the United States Congress building after Republicans began reversing a series of in-house green initiatives undertaken by Democrats.

The about-turn was announced by a press aide to John Boehner, the speaker of the House of Representatives, who tweeted on Monday morning: "The new majority – plasticware is back".

When the Democrats held the house, the former speaker Nancy Pelosi put the cafeterias at the centre of a plan to hugely reduce the carbon footprint of Congress.

The ancient power plant in Washington DC a few blocks from the Capitol building, which provides heating and cooling for Congress and the supreme court, was converted from coal to natural gas. Compact fluorescent lighting and energy-efficient vending machines were introduced.

In the cafeterias, polystyrene packaging was replaced with trays and utensils made of biodegradable corn starch. Four separate stations were installed for recycling and sorting. A healthier menu was also introduced in 2008, offering cage-free eggs and antibiotic-free beef.

Items deemed compostable waste, such as coffee cups, were sent to a pulper in a lower basement, which squeezed out all the liquid before dispatching the material by truck to a commercial composting site in the suburbs of Washington DC.

A system that converts the energy of sunlight directly into hydrogen has been discovered at Oak Ridge National Laboratory. Scientists there have managed to design what they call a “biohybrid photoconversion system,” which consists in the interaction of plant proteins responsible with photosynthesis and a synthetic polymer they created.

The Light Harvesting Complex II proteins (LHC-II) in a spinach plant have been determined of being able to self-assemble with polymers in a synthetic membrane structure which can produce hydrogen from water in the presence of sunlight. The researchers used a technique called “small angle neutron scattering” at ORNL’s High Flux Isotope Reactor.
