Cremation or composting? I’d consider the latter.

I’ll spare you some of the squishiest details, but you needn’t worry about your prosthetics, or artificial hips, knees, or other non-biodegradable augmentations. They’ll be filtered out of your soil after three months of, um, well, marinating. The vessel in which this all takes place resembles a rough-hewed barrel-casket, except instead of being draped in satins and velvet, it’s packed with wood chips and straw. The thing also has wheels so it can be rolled around for the oxygenation and agitation needed to compost, sort of like your backyard composter.
