Straw mag?

From CBC.ca:

A Canadian magazine will be making history Thursday — Canadian Geographic is publishing its annual environment issue on paper made from wheat, a first for a North American magazine.

The issue is being printed on sheets made with wheat straw — what’s left of wheat after the grain harvest.

The magazine says adding agricultural waste to pulp from trees could offer farmers a new source of revenue and cut the demand for pulp from the continent’s boreal forests.
