Industrial Applications: Battery Manufacturing and Recycling Facilities

Overview

The battery manufacturing process requires the use of concentrated metal nitrate solutions that result in dilute waste solutions and metal precipitates. Both nickel and cadmium are used in large quantities, and sometimes cobalt is used as an additive. The cobalt used in the creation of the most energy dense lithium-ion batteries is poisonous and extremely carcinogenic.  The lithium-iron phosphate used in lower energy density batteries is better in terms of its carcinogenic effect, but might be worse in terms of the impact on the biosphere.

Exposure to lead is also a primary health concern in battery manufacturing. Any operation in which battery plates, lead scrap, or oxide is handled may be a significant source of lead exposure. Airborne dispersion of lead dust (which settles on equipment, floors and other surfaces) via cross-drafts, pedestrian and vehicular traffic, and dry sweeping, may be an additional source of lead exposure.

Environmental concerns as a result of batter manufacturing include resource depletion, global warming, and ecological toxicity.

Battery manufacturing plants under federal jurisdiction are required to comply with Federal OSHA occupational safety and health standards for general industry (29 CFR 1910).

The Cleanup Process

The EPA designed the following remediation measures for Battery Manufacturing and Recycling Facilities:
  1. Dredging, draining, and treating contaminated sediments
  2. Excavating and treating contaminated soil
  3. Tearing down facility buildings and processing towers
  4. Decontaminating and recycling materials stored at the facility
  5. Excavating contaminated soil from residential yards near the site
  6. Replanting and establishing a thriving ecosystem
Remediation of metal contaminated sediments has important policy implications. Dredging projects produce contaminated sediments which must be disposed and disposal of dredged materials is often problematic. Often such materials are disposed of in sealed underground vaults, but leaching of toxic materials from such vaults has often occurred, often with drastic consequences, i.e. contamination of the groundwater supply.
