These entities' namesake gas, also known as biogas, is mostly comprised of methane produced from anaerobic digestion, and they are lined with impermeable geomembranes to prevent groundwater-contaminating leachate runoff.
Project XL is currently sponsoring several pilots of these entities aiming for increased energy capture and quicker stabilization as opposed to conventional examples. The aformentioned bioreactor form of these sites may be aerobic or anaerobic depending on whether air is injected. These entities' namesake gas, also known as biogas, is mostly comprised of methane produced from anaerobic digestion, and they are lined with impermeable geomembranes to prevent groundwater-contaminating leachate runoff. The first modern (*) "sanitary" one of these, which pioneered the conventional "dry tomb" form, was constructed on the outskirts of Fresno, California in 1930, and a famous former one of these, currently planned to be transformed into a park, was notably reopened to receive debris from 9/11 and is found on Staten Island. Fresh Kills was an example of, FTP, these repositories of municipal solid waste, colloquially known as "dumps".
