What the consumer can do to reduce waste: Buy recyclable and recycle. Buy concentrates. Buy reusable products and containers. Buy in large sizes for frequently used products and only what you need for items you may not use again. Avoid overpackaging: Buy in bulk; reuse bags. Avoid anything labeled ``disposable.'' Use washable napkins and towels rather than paper. Use inexpensive, unbreakable, washable dishes and utensils for parties and picnics. Write to product manufacturers and tell them when you like or dislike their package or product. Companies need to hear that consumers care about waste and recyclability.
