Collins has devised ways to degrade toxic chemicals already in the environment. He formed a spin-off from Carnegie Mellon University, GreenOx Catalysts, to develop and market his products, which have safely broken down anthrax as well as hazardous waste from paper pulp mills. Green chemistry, however, does not exist merely in government or university enclaves. In 2006, the Dow Chemical Company, with annual sales over $50 billion, declared sustainable chemistry as part of its corporate strategy. DuPont, meanwhile, created a Bio-Based Materials division that has focused on using corn instead of petroleum to produce polymers for a variety of applications, from carpets to medical equipment, while also reducing greenhouse gas emissions. Since synthetic chemicals are the basic building blocks of most modern products, from shoes to iPhones to food preservatives, green chemistry can play a significant role in sustainability. Cradle-to-cradle design, earth systems engineering, and virtually every other framework and tool can benefit from more environmentally friendly materials at the molecular level. As John Warner, a key figure in educating companies about green chemistry providing innovation and new materials across sectors, states,

What is Sustainability? The Definition of Sustainability

Nonetheless, there has been some discussion of whether ecological economics should remain an eclectic category or become a defined specialty with concomitant methodologies. Ecological economics tends to use different models than mainstream economics and has a normative inclination toward sustainability and justice over individual preference or maximizing return on investments. Moreover, while mainstream economics continues not to require an environmental education for a degree, some doctoral programs now grant a separate degree in ecological economics, while others offer it as a field for specialization. The location of ecological economics courses within university economics departments, however, suggests that contrary to the founding aspirations of the field, ecological economics has become the purview of economists more than ecologists in the United States.

The science of what we eat, a lack of evidence in medicine, and why useless knowledge isn’t so useless. That’s all this week on Innovation Hub.


Framing Sustainability Innovation and Entrepreneurship

Green chemistry also refers to a journal devoted to the topic (), and one of its associate editors, Terry Collins, has identified steps to expand green chemistry. First, incorporate environmental considerations and sustainability ethics into the training of all chemists and their decisions in the laboratory. Second, be honest about the terms or and the evidence for the harm chemicals cause. For instance, a cleaner, more efficient way to produce a certain product may be progress, but if the product itself remains highly toxic and persistent in the environment, it is not exactly green. Consequently, “since many chemical sustainability goals such as those associated with solar energy conversion call for ambitious, highly creative research approaches, short-term and myopic thinking must be avoided. Government, universities, and industry must learn to value and support research programs that do not rapidly produce publications, but instead present reasonable promise of promoting sustainability.”

To science we owe dramatic changes in our smug self-image

Green engineering, as articulated by Paul Anastas and Julie Zimmerman, is a framework that can be applied at scales ranging from molecules to cities to improve the sustainability of products and processes. Green engineering works from a systems viewpoint and is organized around twelve principles that should be optimized as a system. For instance, one should not design a product for maximum separation and purification of its components (principle 3) if that choice would actually degrade the product’s overall sustainability.
