Several actions can be taken by governments at all levels to support the recycling of construction & demolition industry waste products. One of the most common tactics is landfill disposal bans on recyclable materials in the waste stream. Two examples are the ban on drywall disposal in British Columbia, and the requirement in King County, Washington that all C&D loads with more than 20 percent recyclable material be rejected at the transfer station and sent to a Material Recovery Facility.

The Monterey Regional Waste Management District (MRWMD) has started up its new Materials Recovery Facility (MRF). Supplied by Bulk Handling Systems (BHS), the technologically-advanced recovery system processes up to 80-tons-per-hour (tph) on two lines. The multi-material line processes 30-tph of commercial and residential Single Stream or 40-tph of commercial Mixed Materials, while the Construction and Demolition line handles 40-tph. The $24mm project occupies 100,000 square-feet of the District's campus, which also includes the country's first SMARTFERM anaerobic digestion (AD) system.

The following are seven steps in a typical system for shredding and briquetting old pallets and other types of demolition stream waste wood.
- Storing Raw Material: Old pallets and waste wood from demolition streams needs to be stored out of the elements to keep it dry. Coloured pallets should be sorted out.
- Shredding: Raw material is fed into a shredder for size reduction.
- Sorting: Shredded raw material is conveyed past one of several magnet separators for sorting of nails. An adjustable gap between the transport belt and the vacuum inlet for the hammer mill ensures that nails that have not been sorted out by the magnet separator will fall down and not be sucked into the hammer mill.
- Hammermill: The raw material passes through a hammermill before going into a large storage silo.
- Storing processed material: A large storage silo is used to contain shredded and milled raw material. In a 400-cubic metre silo, at the bottom of the silo there is room for two briquetting presses.
- Briquetting: From manufacturer, C.F. Nielsen, two model BP5500 briquetters, positioned in the silo, will produce a total of approx. 2.5 tons of briquettes per hour. The presses can run unmanned around the clock in a silo that is 400 cubic metres in size.
- Briquette storage: Briquettes are placed in a pile coming directly from the briquetting presses via the cooling lines. Briquettes allow for maximum bulk density, for storage, handling and transport.
