The recovery and distribution of debris from the World Trade Center site following the September 11, 2001, attacks is the subject of a new book, "Scattered Steel: The Afterlife of the WTC." The authors, Samuel and Max Holleran, document how nearly two million tons of material were processed, with many fragments eventually finding their way into memorials across the United States and internationally.
In the immediate aftermath of the attacks, trucks began transporting wreckage from the still-smoldering site to Fresh Kills, then the world's largest landfill, on Staten Island. The volume of debris quickly overwhelmed the landfill, prompting a new plan. Larger steel pieces were first sent to scrapyards in New Jersey, where FBI agents and archaeologists meticulously searched for human remains. Non-metallic fragments continued to be sent to Fresh Kills.
Within months, approximately 95 percent of the steel was sold into the international scrap market. Over 200,000 tons went to wholesalers in India, China, and Turkey, often without full disclosure of the material's origin. By the first anniversary of the attacks, much of this steel was reportedly being repurposed into construction materials and even cookware in Asia.
The remaining steel, including contorted beams, was stored at JFK Airport's Hangar 17 for nearly a decade. As interest in creating permanent memorials grew, pieces were gifted to churches, firehouses, and police departments as recognition for their response efforts. The Church of Saint Francis of Assisi in Manhattan received a piece of crumpled steel in honor of Father Mychal Judge, an FDNY chaplain and victim of the attacks.
Some materials were directly incorporated into memorials soon after the clean-up. Construction worker Frank Silecchia discovered a 17-foot crossbeam, which was blessed and became a symbol of hope. Recovery workers also cut primitive shapes like hearts, crosses, and Stars of David from steel fragments to be passed to families or kept as talismans. In one instance, ironworker William Quinlan described cutting crosses to give to families, providing a measure of comfort.
While the majority of wreckage remained in the U.S., some pieces were sent overseas. A memorial in Ontario, Canada, dedicated to search dogs, includes an I-beam from the WTC. London opened a memorial garden in Grosvenor Square featuring salvaged steel, and later, a larger twisted steel structure was installed in the Queen Elizabeth Olympic Park. Other international installations include a monument outside NATO headquarters in Brussels, one near Jerusalem that lists all victims' names, and the "Memoria e Luce" sculpture in Padua, Italy.
Across all 50 states, smaller civic projects emerged, often assembled on a do-it-yourself basis. Towns would order steel pieces, transport them at their own expense, and mount them on simple plinths, sometimes in unexpected locations like office park peripheries or roadsides. The steel beams are often kept in their original form, serving as a direct reminder of the event.
An exception to this preservation is the seven and a half tons of WTC steel melted down and used in the hull of the USS New York, whose motto is "Strength forged through sacrifice. Never forget." Additionally, aluminum fragments from the WTC were repurposed as protective shields for cables on NASA's Mars Exploration Rovers, Opportunity and Spirit, launched in 2003.
However, the handling of the WTC debris has also been a source of controversy. Despite a painstaking search that identified about 60 percent of human remains, over 1,000 victims' families have not had this closure. They contend that "microremains" may still exist within the rubble at Fresh Kills and have advocated for the material to be moved to a cemetery. A lawsuit filed by the group WTC Families for Proper Burial was dismissed by the Supreme Court. For these families, the distributed memorials take on a heightened sacred significance, serving as proxies for the lost remains and aiding in collective mourning and closure.
