In this Friday, April 19, 2019, photo Katrina Spade, the founder and CEO of Recompose, displays a sample of the compost material left from the decomposition of a cow, using a combination of wood chips, alfalfa and straw, as she poses in a cemetery in Seattle. Spade hopes to use the process, which accelerates natural decomposition when placed in a temperature and moisture-controlled vessel that is rotated, to compost human bodies. (AP Photo/Elaine Thompson)
