Costs With the exception of metals, all the materials markets are fairly low -value unless a capital intensive, value -added processing line, such as producing wood furnish for particle board, is added to the separation facility.There are costs associated with handling all types of materials, source - separated or commingled. 2. Centralized Processing for mixed C &D Center There are a number of semi - automated C &D processing facilities around the nation. In our December 1998 report to the Landfill Owners Group, we reviewed three of them. All have a specific relation with the public entities in whose jurisdiction they operate, ranging from being co- located at a public landfill to free County land to flow control ensuring that C &D waste enters the facility. All offer differential fees for source - separated materials. That economic incentive can be sufficient to encourage separation if the fees for mixed materials are high enough and the alternative destinations for materials are far enough away to cause haul costs to exceed the lower tipping fees such facilities might offer. The results are shown in a table below and have been updated for the current year. Semi - automated recycling facilities for management of mixed construction and demolition waste can divert from 25% to 95% of incoming materials from landfilling, depending on what is permitted to enter the facility, prevailing tipping fees, available markets, and other specific local conditions. The three facilities from which we gathered information handled a minimum of 50,000 tons per year each. We accept about 30,000 tons per year of in- county C &D only. To be cost - effective, these capital- intensive facilities typically handle more than our waste stream alone would provide. The remander of this page is intentionally left blank. Q,
