agro-sequestration

A simplified version of the biolandfill technology used for agro-sequestration. To keep the biomass dry, it’s necessary to use two layers of high-density polyethylene with a combined thickness up to 4 millimeters. The plastic acts as a water diffusion barrier, allowing less than 1.75 micrometers equivalent water thickness to diffuse through annually. This rate of water diffusion can be accommodated for thousands of years by the dry salt-biomass mixture, which can absorb the water without increasing its own relative humidity (water activity) above 60%. Water activity below 60% suppresses all life and all biodegradation. (Image by Eli Yablonovitch and Harry Deckman)

Salting and burying biomass crops in dry landfills could economically capture greenhouse gases for thousands of years
