spent coffee grounds

agricultural residue

 biomass composition

Spent coffee grounds contain large amounts of organic compounds (fatty acids, lignin, cellulose, hemicellulose) and other polysaccharides.

 current disposal methods

Some spent coffee grounds are used as compot, most are dumped into general waste and disposed of through incineration and landfills.

 environmental impact

Spent coffee grounds contain oils and other compounds that makes soils more acidic. In landfills, this creates an acidic leachate (liquid) which can damage the surrounding soil. The decomposition of coffee waste in landfills generates greenhouse gases (GHGs), especially methane.
