An environmentally controlled greenhouse is located near a landfill site and uses the landfill gas to both heat the greenhouse and furnish a clean carbon dioxide enriched product gas to enhance plant growth. The clean CO.sub.2 system product gas is used to regenerate adsorber beds which remove undesirable constituents from the landfill gas. A portion of the landfill gas may also power an extraction steam turbine which heats the greenhouse with extraction steam. The system is controlled to enhance plant growth by adjusting the temperature and CO.sub.2 lev...
[What is claimed is:] [1.]collecting landfill gas (LFG) from the landfill site and transporting the landfill gas to a distribution point near the landfill site,separating the landfill gas into at least a first LFG portion and a second LFG portion,combusting said first LFG portion of the landfill gas and heating the greenhouse with the products of combustion,providing a CO.sub.2 system having adsorber beds,adsorbing the non-methane hydrocarbons (NMO) and reduced sulphur compounds (TRS) from said second portion of the LFG in the adsorber beds,combusting th...
