Towards Environmentally Friendly Chemical Processes

摘要: Increasingly stringent environmental regulations have stimulated chemical manufacturers to develop alternative technologies that produce a minimum amount (preferably zero) of waste and avoid, as much possible, the use toxic and/or hazardous reagents solvents [1–4]. Emphasis is clearly on reduction at source — primary pollution prevention rather than incremental end-of-pipe solutions. Sustainable development benign by design are catch phrases paraphrase this trend towards ‘green chemistry’ [5, 6]. Consequently, traditional concepts process efficiency changing from an exclusive focus yield one assigns economic value eliminating waste.
