Stonyfield Farm (owned by Danone) uses #5 plastic for their yogurt tubs. At first glance, that appears wasteful because it's more difficult to recycle #5. My roommate contacted Stonyfield Farm to ask why they don't use recyclable plastic, and they explained that they calculated the net impact of using different kinds of plastic, including the energy cost of manufacturing, the relative volume of plastic required, and the energy used in recycling. They found that #5 had the least overall impact (because they could use thinner walls and less volume), even if none of their containers are recycled. Recycling is the last priority in "reduce, reuse and recycle". That's also why they use only foil lids for their small yogurt containers.

Stonyfield Farm also offered to recycle any containers that consumers send back to them, but now that #5 recycling is becoming more widespread, it's probably more resource-effective to look for a local recycler.

I once bought something from Hanes online, and am now deluged with catalogs from them every month - WAY too much wasted paper. I don't know anything about other SR issues as it pertains to them.
