Green Chemistry

Principle One- Prevent Waste

Green Chemistry

Green Chemistry is "the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances". It is made up of a set of twelve principles that can be used to design or re-design materials and chemical transformations to be safer for human health and the environment. Green chemistry also works save companies money by using less energy and chemicals, thus reducing the cost to preduce the product

Prevent waste

The first principle of Green Chemistry is Prevent waste. This involves the creation of chemicals or products without waste, excess products or anything to clean up. This is based on the idea that it is better to prevent the waste rather than clean it up or treat afterwards. This principle can be considered the basis of Green chemistry, and using this principle, chemists intend to design more efficient processes that minimize the production of waste chemicals.

Chicken Chips

In order to manufacture computer chips and other data chips, many chemicals, large amounts of water and energy are required. The industrial estimate, in 2003, of chemicals and fossil fuels required to make a computer chip was 630 times the weight of the chip, in materials, just to make one chip, so a 630:1 ratio! Using Green Chemistry scientists were able to create different and renewable methods to create computer chips.

Richard Wool, director of the Affordable Composites from Renewable Sources (ACRES) program at the University of Delaware, found a way to use chicken feathers to make computer chips, seeing as the poultry industry leaves behinds 3 billion pounds of waste feathers in the US each year. The protein in the feathers was used to make a fibre and resulted in feather based, printed circuit board that is twice the speed of traditional circuit boards.


Methods that have been updated with Green Chemistry generally improve performance and benefit us. These include improvements in human health, environment and economy and business.

Richard Wool's Chicken Chips have many benefits to both the environment and businesses including:

  • Lower potential for global warming, ozone depletion, and smog formation due to less production of carbon dioxide
  • Less chemical disruption of ecosystems from less use of fossil fuels
  • Less use of landfills, especially hazardous waste landfills from less waste being produced
  • Higher yields for chemical reactions, using smaller amounts of feedstock to produce the same amount of product
  • Reduced waste, eliminating costs associated with hazardous waste disposal
  • Better performance as it is twice as fast as traditional chips
  • Reduced manufacturing plant size or carbon footprint through reduced waste and pollution
  • Improved competitiveness of manufacturers as there product is environmentally friendly and may be ore appealing to customers
