Concrete, a primary building construction material, is the world’s most consumed man-made material. About 500 million tons of concrete were consumed in the United States in 2005. Production of cement (the binder in concrete) is an energy-intensive process and it contributes about 5 percent to global carbon dioxide (CO2) emissions. Production of each ton of cement results in the emission of 1 ton ...

Every year, an estimated 19.5 million illnesses occur in the United States due to consumption of unsafe drinking water and result in productivity losses of the order of $20 billion. The burden of waterborne illnesses is expected to increase due to the emergence of more virulent microorganisms and an increase in the number of sensitive subpopulations, which include older people, young children, pre ...

Metal working fluids (MWFs) are designed to cool and lubricate manufacturing operations. This $1 billion industry has not changed much in decades and today has a number of problems, including an inability to meet new machining challenges (e.g., titanium machining in aerospace applications), Employee Health and Safety (EH&S) concerns, toxic waste disposal, and cost. Today’s MWFs represent a signi ...

Gas chromatography (GC) systems deliver incomparable performance for the analysis of volatile organic compounds (VOCs). High-speed GC techniques can deliver these advantages with near real-time results. Significant cost reduction can be gained by providing real-time decisions in the field. Chromatofast, Inc., has developed a proprietary, high-speed laboratory GC inlet system that possesses feature ...

SLUDGE WASTE CONTAINING CR(VI) FROM CHROMIUM PLATING OPERATIONS IS CLASSIFIED AS HAZARDOUS AND ITS DISPOSAL IS A MAJOR CONCERN. IT CAN BE RECOVERED FOR FUTURE METAL USE IN REMELTING OPERATIONS, CAN BE STORED, OR CAN BE DISPOSED AFTER MODIFICATION TO A LEGALLY ACCEPTABLE FORM. IN PHASE I, THE CONVERSION OF SLUDGE WASTE FROM CHROMIUM PLATING OPERATIONS INTO FERROCHROMIUM ALLOYS IS PROPOSED. BY MEANS ...

Chromium plating sludge waste from hard and decorative chromium platingoperations is classified as a hazardous waste and its disposal is a majorenvironmental concern. Climax Research Services (CRS) will develop techniquesto recycle the chromium metal values in the sludge back into the domesticmetallurgical industry as purified aluminothermic chromium metal. This proposaladdresses initially the h ...

Not Available Military information systems are becoming increasingly dispersed, appearing in weapon systems, satellites, and in the pockets and palms of combatants, they are perceiving the physical world closer than ever before, creating new opportunities for controlling the battlefield environment. In order to exploit these opportunities, information systems will need the ability to sense, compu ...

Sludge waste from many plating operations is classified as a hazardous waste. Its disposal is a major environmental concern. In this proposal, the nickel values in sludge that result from electroless nickel plating and from chromium plating will be extracted and recovered as pure nickel metal. The sludge first will be converted into a purified nickel carbonate using an innovative combination of py ...

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 ...

DUE TO THE ADVERSE EFFECTS ON AIR QUALITY, THE ENVIRONMENTALPROTECTION AGENCY IS VERY CONCERNED ABOUT CONTROLLING PARTICULATE EMISSIONS FROM DIESEL TRUCKS AND BUSES. IN 1991 AND 1994 NEW, AND VERY STRINGENT, FEDERAL EMISSIONS STANDARDS ARE SCHEDULED TO TAKE EFFECT. AMONG THE ALTERNATIVES AVAILABLE TO PERMIT COMPLIANCE WITH THESE STANDARDS IS THE DIESEL EMISSION OXIDIZER (DEO) APPROACH. THE DEO IS ...
