A client needed a cost-effective solution for the re-use or disposal of large stockpiles of coal waste. These stockpiles posed an environmental, space, and economic liability. The challenge was developing an agglomeration process to convert the coal waste into a value-added product solving the potential liabilities and creating an additional revenue stream for the client.
The client engaged HRL to provide comprehensive technical expertise and develop a briquetting product right through from concept to pilot-scale demonstration, and finally, a commercial plant producing and selling briquettes. HRL assisted the client through all steps of product development through to commercial operations, including:
HRL successfully provided the technical support required to convert the initial concept into a commercial plant producing and selling briquettes.
