Manufacturers of writing paper need to add mineral "filler" to paper pulp if the paper made from the pulp is to look white. ███████ ████ ███████ █████ ████████ ████ ████████ ██ ████ ███████ █████ ████ █████ █████ ████ ████████ █████ ████████ ████ ██████ ████ ██ ████████ ██ ████ ████ █████ ████ █████ ████████ ██████████ ███████ ███ ████ █████████ ███ ██ ███████ ██ █████ █████████████ ██ ███ ███████████ ██ ███████████████ ████████████ ████ ██ ███ ███████ ███████ ████████ ██ ███████ █████ ████ ████ ████████ █████ █████ ██ ███████ █████ █████ ██ ███████ ██████ █████ █████████████ ████ ████ ██ ███ ████ ██████ ████ ████ ███ ████
Summary
If recycled writing paper replaces non-recycled, there will be more filler used than is currently. Why? Because recycled writing paper requires more filler than non-recycled in order to appear white,
Notable Assumptions
The author’s conclusion only holds if we actually need writing paper to appear white. If not, then there’s no support that we would use more filler, because we wouldn’t care about how the paper looks.
