It is also a strong contributor to sustainable design, as the use of slag cement in concrete saves virgin raw materials, consumes less energy and makes use of an industrial by-product material
that might otherwise be disposed of in landfills.
It makes use of an industrial by-product material
that might otherwise end up in landfills, and avoids the use of virgin raw materials.
After an analysis by the North Carolina Department of Agriculture & Consumer Services (NCDA&CS) Agronomic Division, the data indicated that the by-product material
discharged from the GaiaRecycle system contained a significant amount of valuable nutrients that can be utilized in order to prevent all of the university's leftover food from being discarded into landfills.
It also provides significant sustainabillty benefits, as the use of slag cement saves virgin raw materials, consumes less energy, and makes use of an industrial by-product material
that might otherwise be disposed of In landfills.
The nutrient content of GaiaRecycle's by-product material
discharged from the system after processing food waste was recently analyzed by the North Carolina Department of Agriculture & Consumer Services (NCDA&CS) Agronomic Division.
The NRC letter stated "We have received [the INIS] application, including an Environmental Report and an Integrated Safety Analysis Summary, dated December 30, 2009, to possess and use source and by-product material
at the proposed International Isotopes Fluorine Products, Inc.
announced today that its wholly owned subsidiary, Waste Control Specialists LLC ("WCS"), received notification that the Executive Director of the Texas Commission on Environmental Quality ("TCEQ") has: (i) filed his Response to Public Comment on the application by WCS for a radioactive material license authorizing by-product material
disposal, (ii) prepared a final draft license for the disposal of by-product material
at WCS' site in Andrews County, Texas and (iii) made a decision that the final draft license meets all statutory and regulatory requirements and recommended the issuance of the license to the TCEQ Commissioners.
The amendment of USEG's State of Utah by-product material
license, which is currently on standby status, is in progress for full operational status.
Materials Characterization and Test Methods: Improve the methods used to quantify the physical and chemical characteristics of industrial by-product materials
, and improve our understanding of how they interact chemically with portland cement.
In addition to potash, the company plans to extract and sell by-product materials
including magnesium sulphate products - often used by farmers across the world to correct soil deficiencies - and gypsum, the primary product used to manufacture plasterboard.
CSIRO project leader Dr Grant Douglas says the use of abundant, low-cost by-product materials
generated from mineral processing offers a potentially cost-effective, environmentally friendly way to remove nutrients from wastewater.
It may also include evaluation of process redesign alternatives to use by-product materials
and estimated costs or savings impacts.
