Some time ago we released KEWO, our tool for keeping track of the wastes produced in a company (companies in Poland are required to do this). KEWO is a SaaS application working in the cloud and now we are offering it as a freemium. The free version lets you do almost everything you want. There is a paid version that adds some features. If you are a company in Poland and are interested please take a look at (Polish only): www.kewo.com.pl.
