Waste Recovery & Utilisation

EScience Associates have been involved in the development of fly-ash and gypsum recycling processes to enable the reuse of the wastes generated by coal burning in boilers during steam raising and burnt lime use in flu-gas desulphurisation. These wastes hold potential for reuse on-site as well as utilisation as additives in various unrelated production processes because of their chemical properties. Projects of this nature included the identification of waste use alternatives and possible treatment processes to yield chemically desirable wastes that could be reused in origin processes or could be moved to unrelated industries as bulk additives to those products.
