The highly versatile, nutritious and rather tasty legume known as the humble soybean — utilized by Chinese culture as far back as 3500 B.C. — is one of the world’s most valuable commodities. Yielding 15 times more protein per acre than animals raised on the same amount of land, it’s no wonder why the green bean (which, incidentally, is also available in myriad colors, from burgundy and yellow to marbleized brown) is highly coveted. With record high plantings of 78.1 million acres in 2010 (just in the United States alone), it stands to reason that we must be doing far more with it than merely just chowing down.
Indeed, we are. In addition to creating various planet-friendly meat substitutes, oil, animal feed, alternative fuel and industrial products such as soy-derived cardboard, cosmetics, biodegradable sunscreen, clothing, candles, soap and automobile parts, we also convert the pear-shaped oilseeds into a diverse array of home improvement supplies. The days of oriented strand board and petroleum-based insulation are now numbered in light of a snappy new crop of planet-friendly, easily renewable soy alternatives that squeeze the most out of the bean, such as:
- Flexible BioH polyurethane carpet backings
- Soy meal/low-value waste wood byproducts/recycled newspaper particle board, plywood and linoleum floor tiles
- Columbia Forest plywood paneling products with soy-based adhesives
- Electrical and household rigid/spray foam insulation such as SoyTherm, SoyOyl and BioBased Insulation
- Caulking compounds
- Adhesives, soy lecithin lubricants and coatings (such as wood and roof sealants)
- Varnish, paint and gel stripper
