Steven,(posted 8406 days ago)it is most admirable that you are aware of your impact on the environment and the effects your photography may have. I might be fooling myself, but I use Xtol and have set up a recycling scheme for all waste. I have a farm in the Oregon coastal mountains, on a river, and must capture all developer products and rinsings and recycle everything. I print digitally to avoid the excessive waste products associated with conventional enlarging, and make an effort to be conscientious and respectful of our planet. perhaps digital will be the ultimate green photographic process.
