In our society, most industrial processes produce waste that can be detrimental to public health or the environment if not properly managed. Hazardous wastes are generated, for example, in the production of cosmetics, pharmaceuticals, detergents, household paint and cleaning products, light bulbs, telephones, televisions and even automotive safety devices such as air bags.
Large volumes of hazardous waste are now generated annually and will continue to be generated at an increasing rate of 75% every year in the future, even under optimistic but realistic expectations.
In light of the risks these wastes pose, many responsible enterprises currently send their industrial waste to commercial incineration facilities for safe and proper treatment. Hazardous waste incinerators, determined by a wide range of environmental protection bodies around the world to be the Best Demonstrated Available Technology (BDAT) for the destruction of organic wastes, are a safe, effective, controlled and monitored means of destroying organic hazardous and industrial wastes.

In fact, if all stationary emission sources were held to standards similar to hazardous waste incinerators, there would not be an air pollution problem today. In China, Metso has delivered a hazardous waste incinerating plant for the SCIPSSWS project at Shanghai Chemical Industrial Park. Many chemical plants are located in or surrounding the park, producing a lot of hazardous waste each and every hour.
A safe incinerating process
The incineration system Metso provided is designed to decontaminate and neutralize solids, liquids, gases and sludges, thus reducing pollution and emissions. Particular attention is being paid to safety systems, which carefully monitor a process handled by two identical process lines, each with a Metso-built, direct-fired kiln that measures 3.81 meters in internal diameter and 15.24 meters in length.
Capable of processing 120 metric tons of material per day (MTPD), the system generates 14 tons of steam per hour for other use.
Emissions from hazardous waste incinerators are the most tightly controlled and are the lowest of the major manufacturing industries. According to the international standard for emission from hazardous waste incinerators, the incinerator is required, at a minimum, to limit emissions to not more than 65 mg of Ash, 80 mg of CO, 200mg of SO2, 5 mg of HF, 60 mg of HCI and 0.1 teq ng per cubic meter.

The results of the test of the incinerators for the SCIP-SSWS project conducted by an environmental monitoring center show that, with Metso's advanced technology and sophisticated equipment, the standards can be easily met.
Metso has more than 50 years' experience in providing indoor process technology, engineering, equipment and services for hazardous waste incineration projects worldwide. Since 1965, Metso has provided approximately 50 rotary kiln incineration process lines and systems to customers all over the world. Metso will continue working with Chinese communities to take environmental protection further.
