Scientist found coffee grounds to be helpful in removing heavy
metal in water

A group of Italian scientists found a way to pro- (a) (b)
cess coffee grounds into a product that can be used to
remove water impurities. In a paper published by ACS
Sustainable Chemistry and Engineering, the team ex-
plained the method of using coffee grounds as water filter 50 μm
by mixing espresso coffee grounds with silicon and sugar.
The mixture is dried into a solid block before submerging
into water to let sugar particles dissolve and leaving holes
in the block. The result is a bioelastomeric foam which can
be used as a filter.
According to scientific tests, the filter is able 2 cm 15kV X35 500μm
to remove 99% of lead and mercury in the water when
submerged in the water for 30 hours, and able to remove
67% of lead when used in a filtration system with running
