Toyota Logistics Services has completed a $US20 million expansion of its Port Newark, New Jersey, vehicle distribution centre.

The 83-acre property can process more than 220,000 imported vehicles a year, before delivery to 371 dealers in 13 states from Maine to Virginia.

The expanded facility now employs 240, up from 150 just four years ago.

The Port Authority of New York and New Jersey, which leases the 83-acre site to Toyota, has praised the company for its voluntary environmental initiatives at the port.

Electrically-powered RAV4-EV shuttle vehicles are used for transportation around the facility. All storm water is filtered before it drains into the bay. A strict no-idling policy restricts delivery trucks from idling more than 3 minutes at a time. The facility has achieved a 90 percent recycling rate for rubbish and materials. Just about the only thing going into landfills from the operation is biodegradable food waste.

Cars and SUVs unloaded from car-carrying ships are inspected at the TLS facility before being shipped by truck or rail to dealers throughout the north east. Options and accessories tailored to the US market are also installed - everything from floor mats and owner's manuals to spoilers, trailer hitches, running boards, custom exhausts, alarms, satellite radios and DVD entertainment systems. The work is done on two platform conveyors and dozens of service bays in the largest of the buildings on site. A paint and body shop can repair any damage that occurs during shipment.

An additional 280,000 US-built vehicles a year are handled through railheads at other TLS facilities in Port Newark, Annapolis Junction, Maryland, and Brookfield, Massachusetts.

Toyota sells about two million vehicles a year in the US More than 60% are produced in 11 North American vehicle and parts plants, with two more under construction. The remainder are imported through ports in Portland, Oregon, Long Beach, California, Jacksonville, Florida, and Port Newark.
