I have just started using coffee grounds from the Jura Giga x7 bean to cup coffee machine in our office on my garden as compost. Having done some homework there does indeed seem to be a groundswell of opinion that it makes very good compost. as you might imagine all of the bean to cup coffee machines that we provide create a very large amount of used coffee grounds. If it proves to make good compost then not only might I benefit by having a lovely garden but the environment will benefit from less waste being put into landfill. I will let you know how I get on with it.
