In some cases it is used as biofuel but not solely. Have been to one of the biggest recycling units in Germany where all organic material was used for making biofuel/biogas and they had also rests from restaurants and coffee shops, which included coffee. Was interesting to see.

Using it for roads is still a waste due to the high cost impact of it and scarce resource.

The future is bright do, as a lot of materials are reinvented for different purposes.
