The feasibility of co-composting Ramsey County (Minnesota) solid waste with sewage sludge from the metropolitan water treatment plant in St. Paul is analyzed. The potential of co-composting the wastes to produce a marketable product is discussed in the context of six major criteria. These are accessibility of market demand, capital at risk, total system economics, technical reliability, system flexibility, and barriers to implementation. This initial summary discusses accessibility of market demand and capital at risk in detail. The study concluded that all of Ramsey County's solid waste could be reduced in mass and volume through co-composting with sewage sludge. Because waste generation may be decreased over the long term through recycling and other methods, a conservative planning scenario was developed for combining 273,750 tons/year of Ramsey County solid waste with 273,750 tons/year of sewage sludge to produce 219,000 tons/year of co-compost.
