Choose Safer Plastic Containers: Understanding the Numbers
By Dr. Alan Greene
 
For many families, the kitchen is the center of domestic life and the favorite room in the house. We come home, we head for the kitchen to have a quick snack, a glass of water or cup of tea. You’ll be spending more time than ever in the kitchen with your baby, who will also come to associate this room with good smells and tasty meals.

The kitchen is also a room where your efforts to go green can have an immediate and powerful impact not just on the health of your child but also the planet. Every bite of food you and your baby take is an investment in your bodies’ future.

Plastic Guide

To avoid plastics that can be harmful to your baby and the environment, get to know the easy-to-identify plastic recycling codes you’ll usually find on the underside of the bottle or packaging. Look for these numbers and symbols before you buy; they will help you find products that are kinder to the environment and safe for your baby.
  • The safer plastic choices are coded 1, 2, and 4. Try to avoid 3, 6, and most 7s. Although technology exists to recycle most plastics, some centers offer only recycling of select plastics (such as numbers 1 and 2).
  • Code 1: PET or PETE (polyethylene terephthalate). Found in soda, water, and cooking oil bottles. Can be recycled once, then it’s made into new secondary products, such as textiles, parking lot bumpers, or plastic lumber—all unrecyclable products.
  • Code 2: HDPE (high-density polyethylene). Found in toys and bottles containing milk, juice, detergent, water, shampoo, and motor oil. Recy­clable once into products similar to those for code 1 plastics.
  • Code 3: PVC (polyvinyl chloride). Found in pipe and tubing, shrink wrap, and a few food and detergent containers. May be discarded at the re­cycling plant. AVOID
  • Code 4: LDPE (low-density polyethylene). Found in soft, flexible plastics such as those used in bags for dry cleaning, produce, and garbage.
  • Code 5: PP (polypropylene). Found in hard but flexible plastics, such as those used for ice cream and yogurt containers, drinking straws, syrup bottles, and diapers.
  • Code 6: PS (polystyrene). Found in rigid plastics, such as those found in coffee cups, meat trays, plastic cutlery, and take-out food containers. AVOID
  • Code 7: Other (including polycarbonate, nylon, and acrylic). This is a grab bag symbol. It includes polycarbonate, an important source of BPA, and found in baby bottles. But it also includes some of the newer, compostable green plastics, such as those made from corn, potatoes, rice, or tapioca. AVOID number 7, unless it is labeled as one of these new bio-based plastics.  ....read more
