I would be thrilled to receive a product in a recycled jar! I would also be happy to get something in a cereal box. Everyone should do their part to reduce waste, businesses included.
However there are probably many who don't agree. Perhaps you could put a blurb on your site that plays up the recycled jar part. Like make it one of your key selling points that you reuse and sterilize - spin it as though there is no question that this is a positive thing. The way you market a product can make all the difference so if you put that right in your description more people would probably think its a good thing.
