The ideal refillable packaging....

I've been trying to figure out what's the ideal refillable packaging. Let's face it, a lot of our day to day purchases are consumables. And we don't need the best container every time we buy laundry detergent or juice. Today I was buying some cleaning supplies, and I was happy to find out that "Method" sold some of their products in refill packaging. It's a good value but you still have plastic. I started thinking, would it be better to sell the refills in half gallon milk packaging and pour it into the original package? Or would it make more sense to sell refills as concentrate that you mix yourself. Think about it, most cleaning products are mostly water.

So can we move to a refill economy, we do it for pre-paid phones, can we do it for other things. Some ideas for your green life:

- Buy juices as frozen concentrates
- Buy your soap in bulk containers, soft soaps often come in packaging with dispensers but you can buy refills without the dispenser.
- Pastas can be bought in bulk, but most come in paper packaging that it's hard to beat.

What else will help create a refill economy?
