The food inside has an expiration date too. As long as your container exceeds that, all should be well for most cases, no? That leaves two necessary improvements: 1. Decreasing the loudness and crunchiness of the sound, and 2. Controlling the biodegradability of the material. > Also, overall it probably takes more energy to produce these materials than recycling existing plastics. Are you taking into account the future cost of de-plasticking oceans, rivers, streams, and other contaminated sites? That should be included too. Deferred costs are still costs.
