A Global Initiative for the Advancement of Waste and Byproduct Research

All human and industrial activities result in generation of waste and byproducts. In the U.S. alone, the amount of waste and byproducts generated on an annual basis is measured in hundreds of millions of tons. At GWRI, our mission is to advance the development of sustainable technologies and policies for more effective management of these materials.

Continual technological innovations and the emergence of new industries require ongoing development of strategies and effective adaptation of existing methods to improve waste management. New waste and byproduct streams, such as those containing nanoparticles, biological matter, and genetic material, pose unique challenges in comparison to more conventional forms of waste.

The research, development, and analysis conducted by GWRI provide critical links between the growing needs of public and industry, the environmental concerns of a global community, and the need to establish resources for future generations.

3D Optical Interferometer Image. Photo: Mr. Derek Manheim. A stitched image of a textured geomembrane is presented. The image was obtained using an optical interferometer (Bruker NP-Flex) acquired by GWRI from a NSF grant. The optical interferometer allows for advanced surface texture quantification of most engineering materials.
