Nike athletic shoes are assembled using adhesives (Section 12.14). Up to around 1990, the adhesives used contained petroleum-based solvents which pose health hazards to humans and contribute to petrochemical smog. In order to improve this situation, the company worked with chemical suppliers to successfully develop water-based adhesive technology, which is now used for the majority of the as- sembly operations. As a result, solvent use in all manufacturing operations in Nike's subcontracted facilities in Asia was reduced by 67% since...
