Today, my boyfriend and I had lunch at JCT Restaurant. They have two different types of tables there. The stainless steel tables didn't have any table cloth or other covering on them. The other tables were made to look like whitewashed boards, but I think they were made from plastic. Anyway, each of these tables had a brown paper table runner that was changed for each guest. The paper looked to be made out of recycled materials since it had little specs in it. We started wondering what was more "environmentally friendly" - these disposable paper table runners, or reusable table cloths.
At one level, you have to consider the manufacturing process. Even though table cloths are reusable, we don't know where they source their materials, what kind of chemicals they use, etc. Plus, they probably aren't washed in-house, so they are probably transported by truck through a service where they are washed in hot water with unknown detergent. The paper on the other hand is probably bio-degradable, but only if disposed of properly. If it is just put into a plastic trash bag to head to the landfill, that advantage would be lost.
Trying to figure out tradeoffs like these quickly becomes a futile exercise when you realize all of the unknowns in the whole process. At a surface level, reusable table cloths seem to be the best, but that only takes into consideration the usage stage. The whole lifecycle of the product is of importance, but there is almost no way to track this information down, especially to a consumer needing to make a decision in the moment. Ultimately, we figured it would best to use neither of the table covering options since the surface looked easy to clean anyway.
As an endnote, they also put the brown paper down on the plates which seems gratuitous. I crumpled it up and took it with me for composting. On the way out, they had Lemonheads instead of mints. Naturally, I grabbed one for each of us. It was only until we got outside that my boyfriend reminded me that I shouldn't be eating it because of the plastic wrapper. But it was too late to bring it back. In the end, I guess I got rewarded for my bad behavior with a sweet candy treat.
