Problems solved by technology

At present, coffee grounds are mainly used as fertilizers and fuels in foreign countries, with low practical value. In China, they are mostly discarded as waste, which is wasteful and pollutes the environment.
In recent years, people have been exploring its recycling methods, but there are still a lot of discarded phenomena, how to effectively use them and generate high added value is a very meaningful work
