The Recycling Economic Information (REI) Report found that, in a single year, recycling and reuse activities in the United States accounted for 757,000 jobs, $36.6 billion in wages and $6.7 billion in tax revenues. This equates to 1.57 jobs, $76,000 in wages and $14,101 in tax revenues for every 1,000 tons of material recycled.
