The Once and Future Carbohydrate Economy

Monday, April 10th, 2006

David Morris describes The Once and Future Carbohydrate Economy — which has struggled of late against the hydrocarbon economy:

Less than 200 years ago, industrializing societies were carbohydrate economies. In 1820, Americans used two tons of vegetables for every one ton of minerals. Plants were the primary raw material in the production of dyes, chemicals, paints, inks, solvents, construction materials, even energy.

For the next 125 years, hydrocarbon and carbohydrate battled for industrial supremacy. Coal gases fueled the world’s first urban lighting systems. Coal tars ushered in the synthetic dyes industries. Cotton and wood pulp provided the world’s first plastics and synthetic textiles. In 1860, corn-derived ethanol was a best-selling industrial chemical, and as late as 1870, wood provided 70 percent of the nation’s energy.

The first plastic was a bioplastic. In the mid-19th century, a British billiard ball company determined that at the rate African elephants were being killed, the supply of ivory could soon be exhausted. The firm offered a handsome prize for a product with properties similar to ivory, yet derived from a more abundant raw material. Two New Jersey printers, John and Isaiah Hyatt, won the prize for a cotton-derived product dubbed collodion.

The history of fuel ethanol:

After World War I, car companies introduced high-compression engines. Existing fuels caused knocking, a result of uneven combustion. The industry feverishly sought an anti-knock additive. Ultimately, it narrowed the choice to two: ethanol or lead. Ethanol would require 10 percent of the gas tank. To achieve the same effect, lead needed less than 1 percent. The car companies, unsurprisingly, chose lead, and stuck to it even after outcries from the public health community about the effects of leaded gasoline.
