Full Description
The book discusses the major environmental polluting waste materials from industries and particularly stresses upon decontaminating spent pot liner. The book incorporates the author's direct experiences in handling this toxic waste and discusses his world patents and semi-commercial plant operation in decontaminating spent pot liner and recovering its carbon value.
