Abstract
COALITION TECHNOLOGIES, LTD., (CTL) RESEARCH HAD IMPROVED A SIMPLE GAS PHASE TREATMENT (SULFONATION) OF WASTE RUBBER AND PLASTICS. RESULTS FROM LABORATORY SCALE EXPERIMENTS DONE AT MICHIGAN STATE UNIVERSITY HAVE SHOWN THAT CONCRETE MADE FROM SULFONATED RUBBER AND PLASTIC PROVIDED BY CTL HAS IMPROVED IMPACT RESISTANCE AS MEASURED BY ASTM STANDARD TESTS. IN MANY CASES, WASTE PLASTICS AND RUBBER ARE CONTAINED IN MIXTURES SUCH AS AUTO SHREDDER RESIDUE. THESE MIXTURES OF PLASTIC AND RUBBER ARE COST PROHIBITIVE TO RECYCLE WITH CURRENT TECHNOLOGY. THE SULFONATION PROCESS PROVIDES CHEMICAL COMPATIBILITY SO THAT WASTE PLASTIC AND RUBBER CAN BE DIVERTED TO HIGH PERFORMANCE CONCRETE, THE VALUE OF THE WASTE PLASTIC AND RUBBER CAN BE INCREASED AND THE RESULTING PRODUCT CAN BE SOLD TO THE CONCRETE INDUSTRY. SULFONATION PROVIDES KEY ADVANTAGES OVER OTHER RECYCLING TECHNOLOGIES BECAUSE MIXTURES OF PLASTIC AND RUBBER CAN BE USED.
