Robin Nagle: What I discovered in New York City trash

New York City residents produce 11,000 tons of garbage every day. Every day! This astonishing statistic is just one of the reasons Robin Nagle started a research project with the city’s Department of Sanitation. She walked the routes, operated mechanical brooms, even drove a garbage truck herself–all so she could answer a simple-sounding but complicated question: who cleans up after us?

Robin Nagle is an anthropologist with a very particular focus… garbage

Trash Dance – The Movie

Trash Dance Still – Night Performance. Photo: Andrew Garrison

All over the world, “unseen men and women [...] do the work that most of us do not want to do”: collecting our waste. Seldom, do they get a chance to be in the limelight.

In 2008, former scavengers from India joined leading fashion models on the catwalk in New York.

In 2009, 24 garbage collectors and 16 of their trucks staged a trash ballet in Austin, Texas. More than 2,000 people came to watch. Director Andrew Garrison turned Allison Orr’s choreography into a prize winning documentary that premiered in 2012 and is now available on DVD. Watch the trailer and an amateur video of the original 2009 performance.

During the Great Depression in the 1930s, the US Government launched a series of economic programmes collectively known as the New Deal. The largest  of these programmes, run by WPA, the Works Progress Administration (renamed in 1939 as the Work Projects Administration), employed millions of unemployed people to carry out public works projects. Most famous was the WPA Federal Art Project (FAP) that employed musicians, artists, writers, actors and directors in large arts, drama, media, and literacy projects.

The FAP created over 200,000 separate works including 2,000 posters. Shown  here are several posters promoting sanitation and hygiene from the WPA poster collection of the Library of Congress.

USA: sanitation workers figure in presidential election campaign

“We’re kind of like the invisible people. He doesn’t realize, you know, the service we provide,” says sanitation worker Richard Hayes, who has picked up the trash at Mitt Romney’s Californian house.

Hayes and fellow sanitation worker Joan Raymond appear in an online ad campaign by the American Federation of State, County and Municipal Employees (AFSCME). The campaign suggests that Republican presidential candidate Romney is benefiting from government services while threatening to cut them back. Representing 1.6 million public service workers, AFSCME is supporting President Barack Obama in the 2012 US election.

Caltech’s prize-winning solar-powered toilet – video

A video demonstrates the working of the prototype of the solar-powered toilet that won the first prize of US$ 100,000 in the Reinventing the Toilet Challenge issued by the Bill and Melinda Gates Foundation. The Solar-Powered Self-contained Human Waste Water Treatment System was developed by Prof. Michael Hoffmann‘s research group at the California Institute of Technology (Caltech).

In 2011 the Caltech team was awarded a US$ 400,000 grant to create a toilet that can safely dispose of human waste and reuse water for just five US dollar cents per user per day.

Solar energy powers an electrochemical reactor, which converts human waste into fertiliser and hydrogen, which is stored in hydrogen fuel cells as energy. The treated water can be reused to flush the toilet or for irrigation.

The toilet, which could cost US$ 1,000 or more per unit according to the Seattle Times, is still a prototype and would need to be adapted before it can be launched commercially.
