C&D Processors are regulated solid waste handling facilities
There are 16 permitted facilities in Massachusetts Each processor is required to operate their facilities
according to a documented and recorded waste ban plan These plans describe in detail the staffing levels,
sorting/recycling equipment and floor plan layout necessary to operate the facility
Each processors is required to submit accurate records on all incoming and outgoing material
General Overview
Incoming debris is weighed at the scale house Loads are then inspected for hazardous material
(suspected asbestos containing material) and waste ban items
Approved loads are then unloaded on the plant’s tipping floor
Large easily identifiable materials are separated on the tipping floor and stored in designated areas
The remaining material is pushed up to a feeder pile An excavator with a grapple sits on top of the pile and
feeds the recycling equipment line
How the plant operates
The recycling line separates the material by size 6”- material is conveyed over a magnet to remove
ferrous material and then sent up a conveyor belt and fed into a destoner which uses forced air to remove the heavy material (ABC) while the lighter material is blown out the back of the conveyor belt
The 6”+ material is run over a star screen to remove fines/dirt and then conveyed up a manual sorting line where laborers segregate the material by type
The material is dropped below to storage bunkers
How the plant operates (cont.)

Arriving material gets weighed on the incoming scale
The load is inspected and tipped on the floor
The the material is pushed up to a feeder pile and an excavator trickles the material onto the recycling line
Material is hand sorted and dropped to storage bunkers below
Materials generated at a C&D processing plant
Aggregate Aluminum Cardboard Plastics
Light Iron Gypsum Wood ChipsAsphalt Shingles
Sorted products are shipped to end markets by 100 yard trailers or railcars
