Green Diamond Sand Products controls the only substantial reserve of laterite nickel smelter by-product material
in North America.
We are committed to sustainability in terms of more efficient production, by-product material
recycling and reduced emissions, states Luis Lpez-Remn, head of the Leather business unit (LEA) at LANXESS.
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.
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 makes use of an industrial by-product material
that might otherwise end up in landfills, and avoids the use of virgin raw materials.
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.
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.
The general process in ambient-process performance elastomer recycling is as follows: By-product materials
from the rubber production process are inspected, sorted to maintain product integrity, and then subjected to a preliminary shredding process to obtain a uniform feed stream.
The programme also resulted in 400 tonnes of steam, that had previously been wasted, being recovered and sold on, and other by-product materials
being used for feedstock.
