Subtitle: An Introduction to the New Science of Biodegradable Plastics
Well beyond an introduction - "Alice--Mutton: Mutton--Alice."
- practically a trip to meet the parents. The first few chapters, rehearsing the benefits and costs of petroleum-based plastics, are a little dry, but they leaf out into a discussion with light chemistry (there are diagrams of molecules) of popular plastics and important processes (oxidation, hydrolysis). Once we have reviewed the virtues plastics have and those they lack, we are introduced to various biopolymers in their chemical schema. Later we get a history of early plastics, many of which were bioplastics. (These chapters have charming pictures, including one of a 1941 Ford made with soybean-plastic body panels.)
Then speculation on the economic prospects of bioplastic production, and research programs to speed their profitability.
Finally, recipes! Kitchen chemistry is apparently enough to allow experimental production (the safety warnings are, pretty much, Don't scald yourself with the boiling water; and Don't eat it.) One of the main possible ingredients is glycerol, or glycerin, which is a byproduct of diesel made from fryer oil. There must be a virtuous circle here.
The first recipes are for photo 'glass', buttons, doodads; but we rapidly get to a more practical biodegradable root wrap, for transplanting; and instructions for building a simple test of tensile strength. All sorts of practical idealism; the world may change, and here's how to start.
