History. Mining waste is one type of special waste When EPA proposed regulations for managing hazardous waste under Subtitle C of Resource Conservation and Recovery Act (RCRA) on December 18, 1978 (43 FR 58946), the agency deferred hazardous waste requirements for six categories of waste—which EPA termed "special wastes"—until further study and assessment could be completed .
WASTE HEAT RECOVERY POWER PLANTS IN CEMENT INDUSTRY S K Gupta / S K Kaul Holtec Consulting Private Ltd., Gurgaon, India ABSTRACT In a cement plant, nearly 35% heat is lost, primarily from the preheater and cooler waste gases.
The recovery and utilization of waste heat not only conserves fuel, usually fossil fuel, but also reduces the amount of waste heat and greenhouse gases dumped to the environment. Several different mediumtemperature waste heat power generation for cement production have been
