Sludge from a treatment process using iron was exposed to a mildly acidic solution to investigate iron hydroxide's capacity to collect metals from waste. Batches of iron hydroxide were regenerated and reused 50 times to treat both synthetic and real plating waste. Treatment efficiency was very high and steady, and there was no indication of deterioration in any aspect of process performance. Ov...

New methods for the reduction and remediation of hazardous wastes like carcinogenic organic solvents, toxic materials, and nuclear contamination are vital to environmental health. Procedures for effective waste reduction, detection, and removal are important components of any such methods. Toward this end, polymeric smart materials are finding useful applications. Polymer-bound smart catalysts ...

An increasing emphasis on waste minimization has prompted research aimed at replacing common synthetic techniques with greener alternatives. In biaryl synthesis, direct arylation1,2 is an emerging alternative to Suzuki and Stille couplings;3 however, a more efficient strategy would involve the direct catalytic crosscoupling of two arenes without recourse to stoichiometric activating groups (eq ...

There is growing environmental concern with the methods of waste disposal used for handling hazardous materials in the metal finishing industry. A resulting need exists to develop and implement the best existing and potential technologies for waste minimization and resource recovery. The objectives of this study were to identify and briefly describe both existing and potential future methods fo...

A continuous end-to-end synthesis and purification of diphenhydramine hydrochloride featuring atom economy and waste minimization is described. Combining a 1:1 molar ratio of the two starting material streams (chlorodiphenylmethane and N,N-dimethylaminoethanol) in the absence of additional solvent at high temperature gives the target compound directly as a molten salt (ionic liquid above 168 °C...

Economic growth increases the pressure on environmental issues, thus highlighting importance of waste minimization processes. The management approaches in most European countries have so far been relatively little studied and compared at micro level. main objective current research is to analyze challenges food industry enterprises identify good practices selected countries. used a mixed-method...

It is thought that there a low level of awareness key competencies drive material waste reduction at the construction stage project which has led to impact minimization in industry. This study, therefore, explores for driving projects. Twenty-four (24) factors CW projects were derived from thorough review existing literature. The research adopted quantitative approach whereby questionnaire surv...
