Personally speaking, I have not worked on a product requiring only a single regulatory pathway since about 1999. With this in mind, I do not have any reservations bringing to you the subject of “chemistry.”
Water-based chemistry is making a slow comeback (in the USA, the US Toxic Substances Control Act of 1976 and The Pollution Prevention Act of 1990 and the California Green Chemistry Initiative in 2008; in the Europe, regulation 1907/2006 Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) program) as a subset of “Green Chemistry.” The 12 Principles of Green Chemistry help lead companies in the direction of cleaner processes and higher profits. Taking it a step further and pulling from the influence of Biomimicry directs us to utilizing water as our main solvent.
“Green chemistry, also known as sustainable chemistry, is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Green chemistry applies across the life cycle of a chemical product, including its design, manufacture, and use. Green chemistry technologies provide a number of benefits, including:
- reduced waste, eliminating costly end-of-the-pipe treatments
- safer products
- reduced use of energy and resources
- improved competitiveness of chemical manufacturers and their customers.”
- Designing processes to maximize the amount of raw material that ends up in the product;
- Using safe, environment-benign substances, including solvents, whenever possible;
- Designing energy efficient processes; and
- Implementing the best form of waste disposal: not to create it in the first place.
- Prevent waste;
- Design safer chemicals and products;
- Design less hazardous chemical synthesis;
- Use renewable feedstocks;
- Use catalysts, not stoichiometric reagents;
- Avoid chemical derivatives;
- Maximize atom economy;
- Use safe solvents and reactions;
- Increase energy efficiency;
- Design chemicals and products to degrade after use;
- Analyze in real time to prevent pollution;
- Minimize for the potential for accidents.
Why should we go back to using water as a solvent? Water-based chemistry, generally speaking, has simple operations, high synthetic efficiency (energy & reaction times), safety benefits (in the lab, waste streams, end products), the reactions are low in cost and there is a high potential to generate new synthetic methodologies that can that can be patented to protect your product.
1) Who makes the toughest ceramic in the world? It self assembles, can be synthesized at low temperatures (~50°F or less), and uses easily obtainable constituents. You may have guessed this one right off the bat – the red abalone (Haliotis rufescens) shell made mostly of CaCO3. (Biomimicry 3.8 Institute, 2012)2) This one is a bit harder: what creature makes a skin that is extremely lubricious, more abrasion resistant than steel and is made primarily from a form of sugar? The North African sandfish skink (Scincus scincus). (Biomimicry 3.8 Institute, 2011)
3) If Pfizer made the move to updated and greener technologies, they could make an additional $200 million dollars per year JUST in reduced waste fees. (Berkeley W. Cue, 205)4) Merck spent $34 million dollars to remove methylene chloride from their Primaxin manufacturing line for an annual cost saving of $14 Million (2.4 year return on investment). (Berkeley W. Cue, 205)
- Gets you out of storing and handling hazardous waste (reduces overhead by utilizing less square footage and potentially reduced insurance costs, increased employees safety);
- Reduces or eliminates hazardous waste removal (reducing cost of disposal);
- Has easy, fast, and low cost reactions (all add to the bottom line);
- Allows you to tout the “greenness” of your company (marketing!*); and
- Is potentially safer for the doctor and the patient (after all, isn’t this REALLY the bottom line in our industry?)
