| 摘要： | In 1999, the North Carolina Department of Transportation (NCDOT) decreased landfill waste by nearly 4,000 tons (3,628 metric tons) through recycling and waste-reduction activities. These efforts yielded nearly $50,000 through the sale of recycled materials and saved the department more than $500,000 in disposal costs. The mission of NCDOT's Resource Conservation Program is to improve markets for recycled products. When bridge demolition is required, this work is usually awarded to the contractor responsible for building the replacement bridge. As part of the contract, NCDOT retains items such as traffic equipment or aluminum guardrails for use in future construction projects. Recycling is not traditionally associated with right-of-way acquisition. However, instead of demolishing homes through traditional methods, the department permits Habitat for Humanity to partially disassemble them and store the materials in Habitat's reuse center. Highway signs are recycled using an environmentally sound high-pressure water system. In addition to recycling office waste, NCDOT itself is also proactive in reducing waste generated in the field. The ferry division recycles recovered bilge oil, used engine oil, brass, copper, steel, and other metals from operations at the shipyard. The rail division recycles lead acid batteries, oil filters, and used oil during maintenance work. The department's motor fleet reuses antifreeze, recycles lead acid batteries and motor oil, and retreads vehicle tires. In 1998, 70,000 pounds (31.75 metric tons) of recyclable waste was collected from rest areas. |
