Reader Question: Biodegradable Bottles

Question from Rip in San Francisco: I’ve heard there is bottled water for sale that comes in biodegradable bottles.  Is this true or a marketing ploy?  Is it something I should consider if I absolutely have to purchase bottled water for kid’s sporting events and emergencies for the trunk of the car?

Response: While biodegradable bottles are certainly better than non biodegradable bottles, they are bottles nonetheless. Under the right conditions (high heat, moisture, and micro organisms) the bottles will break down into water, carbon dioxide and organic material. So, if you "absolutely have to purchase bottled water", biodegradable bottles are a better choice. But the best choice is always to use a reusable bottle and fill it with good 'ol tap water!

Thanks for your question!
