You are watching: How much does a napkin weigh


Dear Pablo: through the energy and water offered in washing and drying, isn't the actually more environmentally friendly come use paper napkins rather of cotton?Cloth napkins not only use water in washing and also a lot of of energy in drying but the do of lock is also not insignificant. Cotton is a very irrigated chop that likewise requires a many biocides and defoliant chemicals. In many cases napkins are actually make from linen, i m sorry is made from the yarn of the flax plant, and also is significantly an ext environmentally friendly. Extr considerations encompass the reality that document napkins are provided once, while fabric napkins can be used multiple times. The course, in the case of restaurants, girlfriend don't desire a napkin used twice!Setting increase the Napkin analysis

I begin by weighing some napkins. My file napkins weigh only 4 grams each, if my noodle napkins weigh 28 grams, and linen napkins weigh 35 grams. Of food the precise weight will certainly vary however the loved one weights will be roughly the same. I am again turning to James Norman, a life cycle analysis expert and the director of research at planet Metrics for several of the data that ns need.

making Napkins

As stated already, producing cotton is no a an extremely environmentally familiar process. In fact, each 28 gram noodle napkin reasons over one kilogram that greenhouse gas emissions and also uses 150 liters that water! by comparison, the paper napkin reasons a mere 10 grams that greenhouse gas emissions and uses 0.3 liters that water use while the linen napkin causes 112 grams that greenhouse gas emissions and also uses 22 liters the water.

Washing Napkins

Based top top an average washing machine, each napkin will reason 5 grams of greenhouse gas emissions through the electrical power used by the motor, and 1/4 liter the water. In addition to this impacts, the laundry soap used may have actually downstream results on aquatic life. You have the right to reduce the influence of washing by washing in cold water and also using biodegradeable and also phosphate free laundry soap.

dry Napkins

Drying napkins causes about 10 grams the greenhouse gas emissions per napkin. Of course, to mitigate this come zero you might line dry. One of the advantages of the paper napkin is, that course, the you don't incur the emissions or water use from washing and drying.

So how do the Napkins compare?

If you add up the emissions from growing the life materials, production the napkins, and washing and also drying, the paper napkin is the clear winner with 10 grams the greenhouse gas emissions vs. 127 grams because that the linen and also 1020 grams because that the cotton. Of course this isn't a same comparison because it assumes only one use. Instead, we should divide the life material and also manufacturing emissions by the number of uses end the life time of the napkins.

Napkins in the restaurant

In a food company scenario we have the right to assume that the napkins room too worn the end or soiled come be offered after about 50 uses. V this assumption, the emissions because that the noodle napkin are 35 grams every use and also for the linen napkin room 18 grams every use. The water usage is 3.3 and 0.7 liters, respectively. Include to this the reality that restaurant napkins are frequently washed utilizing a far-reaching amount the bleach to store them glowing white. Of course the emissions and also water usage for the record napkin continue to be at 10 grams and also 0.3 liters.

Napkins in the house

At home you more than likely aren't walking to be washing your napkins after each use. In my residence we have found that washing the napkins every week is sufficient. With this assumption, how do the reusable napkins stack up to record napkins? over the food of a year you might wash her napkins 50 times and also during the very same time you could go v 350 (50 x 7) record napkins. This scenario is much an ext favorable towards the recycle napkins, through 5 grams of greenhouse gas emissions because that the noodle versus 10 grams for the single-use record napkins. The linen napkin was also lower at 2.5 grams. In regards to water use, the noodle is still higher (0.5 liters) 보다 the file napkins (0.3 liters), and the linen is the lowest, at 0.1 liters.

therefore what Napkins space best?

Surprisingly in the restaurant script the file napkin is the winner, while in ~ home, the towel napkin is king. Right here are some tips for reducing your impact:
