Wasted Again: What Can We Do With All of That Garbage? | The New ...
As summer heats up, our thoughts proceeds to slops--specifically New York Burgh's scraps. As I've mentioned before, it would be laboriously to originate a more environmentally harmful, or more dear system of waste superintendence, than the one we use. To labour--in New York Town we meet the muck that residents location on the subdue and then throw it on the defeat of whopping warehouses that nurse to be positioned in low-revenues neighborhoods. We then bailer it up and care it on to trailer trucks and passenger liner it far to a different place--mostly to landfills (dumps), or waste-to-vitality plants (incinerators). In the old generation, when we had more deserted realty in the conurbation, we dumped the filth in our own landfills. When I was a kid we had the Fount Road and Pennsylvania Drive landfills in Brooklyn--which some of us called the Brooklyn Alps as the drop grew higher and higher. Of indubitably, Staten Atoll had its impossible Freshkills Landfill. The saga is told that there are two good-natured made objects perceivable from outer margin: The Top Fence of China and the Freshkills Landfill. Ah, the profit old duration.
Still, not every diocese has the capacity to barrow their a crock to a landfill in Pennsylvania, so what do other cities do with their waste? In 2005, some of the students in Columbia's Masters in Environmental Body of laws and Strategy Program explored substitute waste stewardship practices around the circle and identified a handful of alternatives to secure-filler.
My buddy Dr. Nicholas Themelis of Columbia's Engineering Seminary has also been exploring technological options to debark-stuffing for well over a decade. He has been amazingly interested in the technological developments in waste-to-force, notably how to reset emissions from litter incineration. As my students and Dr. Themelis have observed, there are many engrossing examples of knowing waste supervision exterior of the Shared States.
A terrific benchmark is waste operation in Barcelona, Spain. In 2001, Barcelona's Metropolitan Environmental Intervention initiated house on two new integrated waste treatment services to direct the megalopolis's waste. The services, called Ecopark 1 and Ecopark 2, now treat more than 40% of the waste they give entr into biogas and fertilizer, and bring back an other 5% for recycling. Ecopark 2 alone processes almost 20% of Barcelona's waste, in part by using anaerobic digestion, a system which processes biodegradable waste without oxygen. The biogas and methane produced by anaerobic digestion are employed to originate verve, a allocation of which the dexterity uses for its own operations.
