I would like to share with you some Clarifications/Thoughts/Interrogations
regarding the new, reusable (and recyclable) Starbucks® cup for hot beverages
(source).
1- "When I talked with Jim Hanna,
director of environmental impact for Starbucks, regarding the cups made out of
100% virgin polypropylene, he told me that one main reason the company turned
to plastic was to cut down on paper waste. Starbucks uses about 4 billion
disposable cups annually and the interior wax coating makes them difficult to
recycle." MISLEADING: Starbucks disposable cups are made from
paper coated with PE (polyethylene). Polycoated cups are recyclable and
repulpable. Furthermore, most paper mills are able to process paper mixed with
other materials such as polycoated paper. Pulper equipped with scavenger could
remove plastic debris. Finally, polyethylene coating represents less than 6.6%
of total basis weight.
2- "The exciting thing about PP is
that it's one of the most versatile resins out there," Hanna said.
"From cradle-to-cradle, PP offers one of the best environmental stories;
it's just a winner all around." MISLEADING: Starbucks reusable cups are made from polypropylene
#5 Plastics. In fact, most polypropylene #5 plastics, unless
they're reused, end up in the landfill since so few
municipalities accept them.
3- What is the carbon footprint of reusable
cup VS disposable cup?
4-
PP based reusable
cups cost $1. However, a major price hike has hit the North American
polypropylene market, sending prices up an average of 15 cents per pound since
Jan. 1. Can we expect a cup price increase in the upcoming months?
5- How about increasing Starbucks
cups recycled fiber content? Cascades, developed recently a new grade of
cupstock paper with 25% recycled fiber content.
6- How about water-based coating for a
fully repulpable and recyclable cups? (The idea is to replace Polyethylene by
water-based coating)
7-
How long do the
cups last? Reusable cups need a lot of carefulness/attention/love: not
lose them, not crush them, and not forget to bring them…
