The biannual Arlington Environmental Collection and Recycling Event, or E-CARE, returned to Thomas Jefferson Middle School this weekend, drawing an estimated 1,239 to the event, according to Arlington County Department of Environmental Services spokeswoman Shannon Whalen McDaniel.

E-CARE allows county residents to dispose of hazardous materials like paint, solvents, garden chemicals and items containing mercury, and to recycle electronics, bikes, small metal items, shoes, eyeglasses and certain medical equipment.

The county collected an estimated 11.5 tons of electronics, more than filling one tractor trailer — a bit more than half of what was collected at the same event in April.

The county also collected about 41.5 tons of household hazardous materials, more than what was collected in April.
