- 33- Separation program costs involving manual picking will vary, depending on the system and amount of labor time. In order to break even, the program must generate enough revenue from the mate- rials to recover costs of wages, including fringe benefits and transport costs. Probably the most extensive program today is in California, where excellent corrugated markets, availabllty of a minimum-wage labor force and favorable weather provide the ingre- dients for a successful program. The economics of mechanical separation programs are better known because of the research completed by existing industries and the National Center for Resource Recovery (NCP~R). The New Orleans demonstration project indicated that capital and operating costs for mechanical separation of recyclable materials were: Glass Aluminum Ferrous $200 per ton $200 per ton $5 to $20 per ton Current market prices in the Region for these materials are: Glass Aluminum Ferrous $40 per ton $460 to $600 per ton $0 to $10 per ton 3. WASTE PROCESSING Full-scale shredder technology is not currently economically feasible at small disposal sites. For a 300-ton-per-day (TPD) facility, current costs are on the order of $7.00 per ton ($7.89 per metric ton). A detailed analysis would be required to deter- mine if the benefits, in terms of saved landfill space and reduced cover, would be sufficient to justify the capital and operating costs incurred to implement shredder systems. Full-scale baling technology is not currently economically fea- sible at small disposal sites. For a 300 TPD facility, current costs are On the order of $5.00 per ton ($5.60 per metric ton). 4. RESOURCE RECOVERY The following discussion of resource recovery program costs is based on the economic analysis in the MPCA Resource Recovery Plan (1979). The plan divided, the recovery systems into the following ranges of size: less than 100 tons per day (TPD), between 100 TPD and 500 TPD, and over 500 TPD. The resource recovery systems anal- yzed included modular combustion units, waterwall incineration, refuse-derived fuel (RDF), dedicated boilers (a type of RDF sys- tem), and rotating compost drum (Dano Process). The consultant preparing the plan for MPCA, Bart Engineering, used historical data whenever possible and published estimates where actual data were not available.
