Hubbell Galvanizing - It's us or Rust

Recycling & LEED Certification

At Hubbell Galvanizing, we are constantly searching for ways to minimize our environmental impact, reduce resource use, and increase environmental sustainability. We do this by managing the materials we buy and reuse those materials in our manufacturing process. And that helps earn you points toward LEED Certification.

Recycled Supply:

Seventy percent of the zinc we buy is recycled. All of the acid we buy is a byproduct of the zinc refining process, and 98 percent of the steel we buy is recycled scrap.

Internal Recycling:

• Zinc: All of our zinc by-products (dross, skimming, etc.) are recycled either on premises or by a zinc supplier.
• Acid: All of the acid is recharged by removing iron and zinc salts that are created during the pickling process. The cleaned acid is supplemented with a small amount of virgin acid and returned to the picking tanks. Iron and zinc salts from the acid recycling are sold for reuse in other manufacturing processes.
• Water: Rainwater is captured in a cistern system and is used in the pickling process. No process water enters the public wastewater system.

How it Helps You with LEED Certification

Because our hot-dip galvanized has so much recycled product – and so much of it is recycled – Hubbell Galvanizing can help you meet the U.S. Building Council’s Leadership in Energy and Environmental Design standards in these two ways:

Credit 4.1 (1 point) “Use materials with recycled content such that the sum of the post consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% of the total value of the materials in the project.”

Credit 4.2 (1 point) “Use materials with recycled content such that the sum of the post consumer recycled content plus one-half of the pre-consumer content constitutes at least an additional 10% beyond Credit 4.1 (total of at least 20%) of the total value of the materials in the project.”
