The trains seem to never stop. One after another, they haul more than 12 tonnes of rubbish daily to the small Chilean community of Til Til, 35 miles (56 km) northwest of Santiago, the equivalent of at least two-thirds of the capital's municipal waste. This town of 17,000 is the last stop for much of the trash produced by a city of 7 million. And now there will be more. The Minister's Committee, a gathering of high-ranking Chilean political officials who decide the fate of controversial projects, last year approved the construction of a sprawling new industrial waste processing facility here. With this newly approved facility, operated by Ciclo, a local waste management company, Til Til will become the last stop for more than half the industrial waste produced from northern Chilean mining region of Atacama to Bio Bio province in the south, according to a report from Chile's Congress. The community has protested, blocking the train tracks that funnel trash north and Route 5, known locally as the Panamerican Highway and a major trucking thoroughfare that transits the city.
