A Technical and Ec Ono Mic Evaluat Ion of the Baltimorelandgar D®demonstration

The demonstration of the Landgard® Plant con­ cept in Baltimore, Maryland, was one of the first attempts in this country at large scale resource re­ covery from mixed municipal solid waste. The Baltimore project has permitted the characteriza­ tion of the Landgard® process from an equipment and operational standpoint. Considerable knowledge has been gained, even though the plant was never fully operational in its design configuration. This paper addresses three major topics to present the major project results: a discussion of the technical and administrative difficulties encountered during the demonstration, a summary of heat and material balance for the process, and a presentation of the economic evaluation of the plant.
