Wastes: other people’s raw materials
Mr Elijah Tauber of the CSIRO Division of Building Research is no newcomer to waste recycling research. He began in 1964 — well before it became fashionable. He can take credit for quite a number of building materials derived from wastes that are now used by the construction industry. His latest idea is a new extra-safe road-surfacing material made from, among other things, steel-plant slag and fly ash.
