Biodiesel may be produced from coffee grounds, either directly by extracting the oils using solvents, [27] by mixing the grounds with methane and a catalyst, [28] or by using the grounds to feed bio-producing algae. [29] In concrete making, 10-15% of the sand used may be replaced with used coffee grounds. [30]
