Scientists from IBM and Stanford University have unveiled discoveries that could lead to the development of new types of biodegradable, biocompatible plastics. The result of a multi-year research effort, the breakthrough also could lead to a new recycling process that has the potential to significantly increase the ability to recycle and reuse common PET and plant-based plastics in the future. Todays announcement may have sustainability implications across a wide range of industries including biodegradable plastics, plastics recycling, healthcare and microelectronics. IBM and Stanford scientists are pioneering the application of organocatalysis to green polymer chemistry, which represents a fundamental shift in the field. This discovery and new approach using organic catalysts could lead to well-defined, biodegradable molecules made from renewable resources in an environmentally responsible way.

In organic chemistry, some types of reaction have inherently better atom economies. Addition, condensation and rearrangement reactions will generally have higher atom economies than either elimination or substitution. For example the addition of chlorine to ethene, to form 1,2-dichloroethane (an important reaction in the manufacture of poly(chloroethene) (PVC)) has an atom economy of 100%:

organic synthesis and sustainable chemistry

Some reactions that have 100% atom economy have poor yields and so it is necessary to consider both measures of efficiency, yield and atom economy. Atom economy is determined in the planning stage, by calculation, while yield can only be found experimentally.

As an alternative measure to yield, the concept of atom economy is used, considered to be one of the key ideas behind the concepts of green chemistry. This expresses the proportion of reactant atoms that end up in a useful product, measuring the number of atoms of the starting materials that end up as products that are wanted and the number that end up as waste. Atom economy is defined as
