A board member with experience operating crush-and-reuse facilities described technical options and cost drivers for concrete and asphalt recycling, and urged the county to compare establishing a local crushing yard to shipping material by rail.
The member (Mike, S3) described equipment configurations (portable and semi-portable crushers), throughput ranges and how labor and union rates affect economics. "We we we employ 40 people all year long," he said to illustrate workforce impacts for larger operations; he also noted that smaller, well-run portable/crush setups can remain viable for many years and that reuse as aggregate or sub-base is common in some regions.
The board discussed whether to recruit vendors to relocate or to use rail to connect with existing processors; members asked staff to obtain cost, labor and throughput data from neighboring operations to inform a later procurement or grant application.
