The roots of the occasional public skepticism of chemicals and chemistry can have its origins traced to the midth century. Green chemistry, then, is an ongoing attempt to address the problems that chemicals and chemical processes can sometimes cause. They were created by Paul Anastas and John Warner, and are essentially a checklist of ways to reduce both the environmental impact and the potential negative health effects of chemicals and chemical synthesis. This tenet simply states that chemical processes should be optimised to produce the minimum amount of waste possible.

Zero waste

The last few decades of the 20th century witnessed growing concerns over the impact of industry on the global environment. These concerns included acid rain, increasing levels of greenhouse gases, fertilizers in streams and rivers, polluted city atmospheres, and a hole in the ozone layer. Some of these are directly attributable to power generation and transport, which have caused major problems and lie outside the direct influence of the chemical industry. However, in spite of an enormous investment over the last 50 years to ensure that the production of chemicals does not have a malign effect on the environment, many of the public, the very consumers of the products, still associate the chemical industry with the worst sorts of pollution. There is no doubt that there are still mistakes and these are generally well publicised in the media but overall there have been significant changes in the operation of the chemical industry that are designed to reduce the impact on the environment.

From the very beginning, identifying and evaluating all potentially high value-added chemicals that could be removed from available renewable feedstocks requires robust, efficient, selective, reproducible, and benign analytical approaches. With this in mind, green and sustainable separation of natural products from agro-industrial waste is clearly attractive considering both socio-environmental and economic aspects. The principal analytical techniques such as solvent, microwave, ultrasound, and supercritical treatments , by-products e. Currently, it can be observed that global sustainability challenges are all closely interconnected, such as pollution, climate change, biodiversity loss, poverty, energy, and food security. As stated by Liu et al. To exemplify this systemic view, Fig.

The Twelve Principles of Green Chemistry: What it is, & Why it Matters

The development and evolution of the chemical industry is directly responsible for many of the technological advancements that have emerged since the late 19th century. However, it was not until the s that the environment became a priority for the chemical industry. But the industry is now rapidly improving, and this changing mindset has provided the backdrop for the emergence of green chemistry.

Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories , mills, and mining operations. Types of industrial waste include dirt and gravel, masonry and concrete, scrap metal, oil, solvents, chemicals, scrap lumber, even vegetable matter from restaurants. Industrial waste may be solid, semi-solid or liquid in form.
