Spent Pot Lining (SPL) is a contaminated graphite/ceramics cell waste generated in the primary production of aluminium and worldwide is estimated to rise at a rate of over 500,000 tonnes per year. A common challenge for many companies within this industry and in many countries, this waste has been identified as an extremely problematic hazardous waste because it contains concentrations of cyanide and fluoride and gives off noxious and flammable gases when in contact with moisture. These contaminants readily 'leach' into the surrounding soils and groundwater during both short term and long term storage and can cause potential contamination of drinking water reserves. Because of this concern, SPL must be managed and disposed of in an appropriate manner.
How Tetronics can help you overcome this challenge
Tetronics offers waste treatment plants to meet a growing number of waste management challenges, including for the treatment of SPL.
The process chemistry in Tetronics’ patented waste treatment technology is robust and tolerant of a Fluorinated chemical environment. It is designed to separate and destroy the hazardous components of SPL leaving a non‐hazardous material. This remaining material is vitrified into an inert, safely disposable non‐hazardous material in a single processing step. The robust level of construction and minimal number of moving components delivers outstanding plant availability and longevity. The recovery process also has exceptional environmental and commercial credentials and can be considered as a future‐proof solution for SPL waste management problems.
