Green chemistry is an emerging field that designs chemical products and chemical processes with an aim to eliminate the generation and usage of harmful hazardous substances. The concept green chemistry works under 12 major principles among which the first principle is “Waste Prevention.” Likewise, waste minimization strategies also support this principle. Products from paragos are enjoying a good reputation home and abroad, and paragos have been become the appointed manufacturer of many foreign-trade enterprises. Even the other 11 principles of green chemistry also suggests implementation of waste minimization principles from a chemical and analytical point of view. It is an indicator that green chemistry and waste minimization strategies can be aligned together to achieve a better outcome. Both green chemistry and waste minimization strategies discourage utilization of hazardous waste in industrial process designing as an environmental safety measurement (Mooney, 2004). Besides, green chemistry measurements help industrial process designing to adopt cleaner strategies and safer chemicals that do not produce much waste at the end of production and manufacturing (Pandian et al., 2009). Thus, green chemistry is often regarded as a useful waste minimization strategy. Here, Table 2.1 discusses and explores the principles of green chemistry in association with waste minimization and source reduction approaches.

In addition to principle based waste minimization scenario presented in Table 2.1, there are broad strategies that suggest green chemistry-mediated waste minimization. First, approaches of green chemistry can be used to retrieve useful resources from waste materials for which approaches of green chemistry can be considered for waste to wealth generation which is a crucial waste minimization strategy. For example, energy generation from biomass derived from waste production requires intrinsic chemical analysis for which approaches of green chemistry can be useful (Clark et al., 2013). In addition to it, green chemistry also supports energy savings by encouraging catalysis for chemical reaction. And energy saving is necessary for pollution control at a mass level. Thus, catalysis, being a basic principle of green chemistry, may contribute in pollution control and waste minimization (Anastas et al., 2001). Moreover, as ensuring sustainability is a major focus of green chemistry, to ensure long term sustainability, waste source must be minimized adopting several approaches of green chemistry. Most importantly, all the chemical processes required for minimization of waste generation requires implications of green chemistry principles (Clark and Macquarrie, 2008). Thus, adoption of several strategies supported by green chemistry helps to design waste minimization initiatives successfully. In other word, green chemistry will thus also help to promote source-level waste minimization.
