... If the technology can be developed, it would solve two environmental problems in one: coffee ground waste, and damage caused by farming herbicides to wildlife and the surrounding natural world.

I vaguely remember from when I was a child my grandmother putting coffee grounds in her potted plants. I'm glad to see that science has finally caught up.

I Compost a lot of material for the garden. I use spent coffee grounds for compost itself, as well as a way to regulate PH.

I have blueberries. Pine straw also works. You can also use a vinegar/water solution in a pinch.
