Is the slag produced environmentally benign?
Shimadzu Techno Research, Inc, Japan conducted tests on the slag produced at the Mihama-Mikata plasma gasification facility in Japan, and concluded that the slag is inert and does not contaminate soil or drinking water. The test used to detect soil contamination, the JLT-46 test, found that the slag sample was below the method detection limit for Arsenic, Cadmium, Chromium VI, Lead, Mercury, and Selenium.
