Paper from Wheat, not Wood

There's an interesting development lurking in your magazine rack (provided you subscribe to Canadian Geographic): paper made from wheat straw—the stem & stalk waste product of grain farming. Indistinguishable from regular wood-pulp paper, printed products made of a percentage of wheat straw are notable not for their tactile qualities, but for their sustainability implications. As agricultural waste, wheat straw is perennially renewable so long as people farm. As a product, monetizeable wheat straw provides a diversified income stream for farmers. As a source of paper fibre, it takes pressure off the forests that traditionally supply pulp, and the species that inhabit them. Rick Boychuk, Senior Editor at Canadian Geographic notes that the "June issue uses sixty percent trees but looks and feels just like any other issue of Canadian Geographic."

Ottawa printer Dollco summarizes the potential impact of wheat straw in paper pulp:

The majority of Canada's paper is currently made from Boreal forests and Temperate rainforests. Straw from Canada's wheat harvest could produce 8 millions of tonnes of pulp—equivalent to the paper volume used by the North American newspaper industry every year. That could result in a saving of 100 million trees each year—without impacting food production or increasing energy inputs, while providing a new source of income for grain growers.

That's a powerful concept—completely re-inventing the North American pulp & paper industry to run on agricultural waste instead of cutting down forests.

IF we can do this with Wheat; imagine what we can do with Hemp?
