One concern for recycle and reuse of scrap tires is the leaching of tire constituents (organic and inorganic) with time, and their subsequent potential harmful impacts in environment. The main objective of this study was to examine the leaching of dissolved organic carbon (DOC), dissolved nitrogen (DN), and selected inorganic constituents from scrap tires. Different sizes of tire chips and crum...

An account is presented of successfully implemented Extended Producer Responsibility (EPR) with recycling to high value products, help overcome barriers and generate confidence in moving towards Circular Economy (CE) business models. A template for organisations proposing recycle a thermoplastic provided by describing appropriate tests considerations implementing the recovery re-use impact poly...

An electrochemical cell comprising a novel dual-component graphite and Earth-crust abundant metal anode, a hydrogen producing cathode and an aqueous sodium chloride electrolyte was constructed and used for carbon dioxide mineralisation. Under an atmosphere of 5 % carbon dioxide in nitrogen, the cell exhibited both capacitive and oxidative electrochemistry at the anode. The graphite acted as a s...

In 1985, the scrap tire industry was created when Minnesota became the first state to develop specific legislation and regulations for scrap tires. Up to that time, many scrap tires, like most solid and household wastes, went into the l1)unicipal dump. Those tires not placed in the dump went into stock piles, some of which still exist today. Prior to 1985, few, ifany scrap tires were processed....

Hexavalent chromium is highly toxic to most living organisms and a known human carcinogen by the inhalation route of exposure. Therefore, treatment of Cr(VI) contaminated wastewater is essential before their discharge to the natural water bodies. Cr(VI) reduction to Cr(III) can be beneficial because a more mobile and more toxic chromium species is converted to a less mobile and less toxic form....

As of 1999, the only artificial systems employed by the U.S. military for the detection of buried landmines were metal detectors.1 Although these detectors can sense as little as 0.5 grams of metal, and thus maintain a high detection probability, they cannot distinguish between a firing pin or a piece of scrap metal. Furthermore, modern landmines can be constructed without metallic parts and wo...
