Reduction and Disposal of Wastes

We reduce and where possible eliminate waste through source reduction and recycling. All waste will be handled and disposed of through safe and responsible methods.

  • Our scrubbers used hydrated lime and limestone. The waste product of the scrubbing process is used in the reclamation of our mining lands, used to treat water that is released from these lands, and used by local area farmers for land treatment. This equals a tractor load of material for each device about every five weeks. None of this material has to be taken to the landfill.
  • Our extrusion process now uses glycerin, a waste product from the production of biodiesel fuel manufacturing in New Kent County, Virginia. This strategy eliminates the need for about 170,000 pounds of soda ash per year that had to be transported from outside a 500-mile radius of the plant. Glycerin use has reduced the material that must be mined, stockpiled, hauled, and processed by about 5%, saving fuel in the firing process.
  • Lawrenceville Brick uses plastic strapping for our packaging. This strapping contains recycled material, and any waste in our strapping process is recycled.
  • Broken brick from our production process is minimal, since our A-grade recovery is over 98% efficient. The broken brick we do have is used for stabilization of runoff areas around the plant and at our mine sites. Any excess is generally used by local loggers to stabilize logging roads. None goes to the landfill.
  • All green trimmings generated during the extrusion and sizing part of the forming are chopped and returned to the process. This amounts to about 10% of the volume extruded.
  • All waste water and wash down water is collected in a sump with no drain. The solids settle out and are fed back into the raw materials and the water is pumped off and used for additive water to the clay for proper extrusion. No process or waste water is released from the plant.
  • All unfired brick waste created in the manufacturing process is recycled back in the raw material mix, saving over 10% of mined materials.
  • Liquid waste created in the coating process is recycled back into the brick body. This recycling of liquid waste reduces our outside water use in the plant by 25%. With this recycling, we are able to assure that no liquid or solid waste leaves the plant.
  • These in-plant reclamation processes mean that virtually no material from the production process must be disposed of, and no liquid waste is emitted from the plant.
  • Through strict quality control measures, we average below 1% defective material in all packages and have a reputation for this level of quality. ASTM specifications allow manufacturers to include up to 5% non-conforming or chipped product per bundle, which has to be dealt with and disposed by the customer.
  • Lawrenceville Brick, Inc., operates in full compliance with all standards of the U.S. Mine Safety and Health Administration, the Virginia Department of Mines and Minerals, the U.S. Environmental Protection Agency, the Virginia Department of Environmental Quality, and the U.S. Occupational Safety and Health Administration.
