Can coffee grounds be used to make cellulose nanofibers?
The resulting microscopic cellulose fibers were uniform in structure. And they could easily be mixed into polyvinyl alcohol—a polymer used to produce biodegradable plastics—to make a composite plastic. The results suggest that spent coffee grounds are a viable substitute to wood for making cellulose nanofibers.

Do coffee grounds decompose?
Coffee grounds in landfills do decompose eventually, but without the oxygen they need, they cannot decompose aerobically like they do in a compost pile. So instead, these coffee grounds are subject to anaerobic decomposition and give off large amounts of methane.

Is coffee grounds organic?
And that's not the end. The degraded coffee grounds are delivered back to the fields as an organic fertilizer. They contain a significant number of elements which are beneficial for the plants to grow. Have you ever heard about the circular sustainable economy approach?

Is coffee a biogas?
As mentioned before, a major fraction of coffee grounds is organic and, if left for a longer time, it degrades and produces CO2 and it smells bad. However, if the same coffee grounds were put into warm temperature and no oxygen presence (anaerobic conditions) bacteria will enjoy eating the coffee grounds and producing biogas. Yes, we are talking methane here - biomethane! In a biogas plant, this process takes place in an anaerobic digester and is accelerated by creating the best possible conditions for micro-organisms and bacteria to multiply, which leads to a highly efficient breakdown of materials.
Step 1: Materials
Materials for one flower pot: - 1 cup of flour - 1 cup of coffee grounds - 1/2 cup of water - Biodegradable flower pot - Plastic container Optional for a logo: - Balsa wood - Carving knife
Step 2: Mix the Coffee & Flour
Add one cup of flour and one cup of coffee grounds to a container. Stir well until you become a light-brownish even mixture.
Step 3: Add Water
Add water in small amounts to the mixture. Stir well each time. The end result should have a muddy texture.
Step 4: Coat the Flower Pot
Coat the biodegradable pot with the mixture.
Step 5: Design Your Own Logo (Optional)
Draw your logo on a piece of paper and cut it out. Transfer it on the balsa wood (or choose an other material) by pencil or just carve around your paper drawing. Sand of the rough edges that might be left over. Place the balsa logo on your flower pot and press gently.
Step 6: Bake!
Your environmentally friendly flower pot is now ready for the oven! Bake the pot for 40 minutes at 120 degrees Celcius (or 248 degrees Fahrenheit). The end result should be sturdy and is pretty water resistant. Incase you want a full water resistance, you can apply a biodegradable varnish layer on the inside.

Does coffee grounds help with water retention?
Amending your soil with coffee grounds will also improve water retention, as it is a type of organic matter that will improve the overall health of the soil, including its ability to retain water. This will especially help plants that like to grow in moist soil, as after rain or watering, the soil will remain moist for longer. A soil that retains water well will also need to be watered less frequently, which can reduce water bills and conserve energy.
