Nearly two dozen plastics recycling processes received a federal greenlight for food and drink applications in the first half of 2024.
Letters of no objection issued by the U.S. Food and Drug Administration allow their recipients to begin marketing their recycled resin for use in food and drink packaging, subject to any limitations spelled out by the FDA.
In issuing the letters, the FDA was convinced the recycling processes would result in contaminant concentrations of 0.5 parts per billion or less in the food, below its “threshold of regulatory concern.”
During the first part of the year, the FDA awarded 27 letters to 21 companies in North America, Asia and Europe, all of them covering mechanical recycling processes except for Alpek, which also received a letter for a chemical recycling process.
Plastics Recycling Update publishes a roundup of LNOs twice each year. The last roundup, which was published in April 2024, covered letters issued during the second half of 2023. The federal database of all FDA LNOs is available here.
The following are summaries of LNOs issued during the first half of 2024, starting with the most recent letters:
