Blast shakes metals markets. (Scrap Industry News).

The terrorist attacks that sent two airplanes into the World Trade Center have claimed the lives of more than 6,000 people. Among the victims were traders, brokers, exporters and others involved in the trading of secondary commodities.

Among the tenants of the twin WTC towers were Carr Futures, a commodities brokerage firm and member of the Institute of Scrap Recycling Industries Inc. (ISRI) and an associate member of the London Metal Exchange. The company's office was located on the 92nd floor of One World Trade Center.

Two weeks after the September 11 attack, about 70 employees of Carr Futures were unaccounted for and presumed dead. Roughly half of the staff of more than 140 employees was not in the office on the morning of the 11th.

Frenkel & Co. Inc. was another World Trade Center tenant and ISRI member. The business insurance company did not lose any employees in the disaster, according to a note published on the company's Web site. It relocated operations to office space in New York and New Jersey.

The operations of the New York Mercantile Exchange (NYMEX), another ISRI member, were disrupted for several days by the widespread damage caused by the attack. NYMEX trading was suspended for several days after the attack. The company's home at the World Financial Center in lower Manhattan is near the World Trade Center complex.

Robin Wiener, president of ISRI, lost a brother in the Sept. 11 tragedy at the Trade Center. A memorial service has been held in New York for her brother Jeff Wiener.

Companies with heavy equipment, including scrap recycling companies and demolition contractors, began arriving on the scene by Tuesday afternoon.
