Why Paper Coffee Cups Aren’t Economical or Environmentally-Friendly

Single-use items such as paper coffee cups may be convenient, but they’re not cost-effective or environmentally-friendly. If you’re trying to do your part to be a good steward of the planet, you’ll want to ditch the disposable items in your life. That means that you’ll need to buy an excellent refillable coffee cup or tumbler that you can use in place of paper coffee cups.

More importantly, once you have said reusable coffee cup, you’ll need to clean, maintain, and use it regularly. It’s not enough to own it. You must take it with you on outings and to the workplace or school, too. You don’t need to take a paper coffee cup from a business going forward because you have a mug that you plan to use for all of your hot beverages.

Reusable coffee cup goes with you everywhere.

When you run out of your paper coffee cup supply, you’ll need to spend money to reorder them. Fortunately, with a refillable coffee cup, you pay for the cup once, wash it, and use it again. You don’t need a special space dedicated to storing your spare coffee cups, either, because you have one that goes with you everywhere.

You also aren’t contributing to an ongoing problem by adding unnecessary waste to the landfill. If you were to use a single-use coffee cup every day for your coffee, you’d throw away, at minimum, 365 cups a year. With a refillable coffee cup, you save 365 cups from entering the landfill.

If you’re committed to reducing waste and still enjoying a hot cup of coffee, you’ll think twice about using paper cups. Although they are readily available nearly everywhere you go, they do create a great deal of waste, and you cannot microwave it if the coffee gets cold. A tumbler that retains heat well will keep the coffee hot for longer without the need to reheat it.

How to Choose a Good Reusable Coffee Cup for Home, Work, and School

You’re busy. We get it. Most people are and need a fast and convenient way to brew coffee and transport it from one place to another.

Rather than stop by the local coffee shop every time you need a boost of caffeine, you opt to brew your beverages at home. Doing so saves you money, allows you to personalize your drink to your liking, and keeps you from making an unnecessary stop during your commute.

Investing in a good reusable coffee cup for home, work, and school is highly advisable.

Investing in a good reusable coffee cup for home, work, and school is highly advisable. It allows you to carry a hot beverage with you while on-the-go safely. You can also refill it in the breakroom or corner coffeehouse throughout the day without creating additional waste and taking a toll on the planet.

Here are some qualities of an excellent refillable coffee cup or tumbler:

  • Made of materials that are food-grade safe and BPA-free.

    Heat causes chemicals to leech into liquids that you’ll later consume. Finding a coffee cup or tumbler that is safe to drink out of isn’t very challenging. Most are food-grade, safe, and BPA-free. They’re also safe to put in the microwave as long as they are not made of stainless steel or metal and don’t have the lid on them. You can clean the refillable coffee cup by placing it in the dishwasher, too

  • Maintains the temperature of the beverage for hours.

    Hot beverages stay warm for hours. Cold beverages are cold for even longer when frozen, or when you add ice to the liquid. If you enjoy iced coffee, you may want to find a cup that you can use for hot and cold beverages.

  • Comes in a size that meets your needs.

    You may only need a small amount of coffee to get you going in the morning. Or you might enjoy one big cup each day. Whichever size you prefer, locate a coffee mug or tumbler that accounts for the amount of liquid you plan to consume. A small cup may do the trick. A large cup may be more reasonable for you because you can always fill it with less liquid when you don’t want to drink a lot of java.

  • Looks and feels like something you want to carry everywhere.

    Aesthetically-pleasing to look at, most coffee cups come in colors, patterns, and designs that meet your needs and demonstrate your personality. They serve as a form of expression for you. You can choose a floral motif or go with a solid color. You may want a stainless-steel cup that you can add a vinyl sticker to as a way of personalizing it. It’s entirely up to you.

  • Has a lid that you can put on it to keep the coffee from cooling too quickly.

    Portability is a big selling point for refillable coffee cups. You can place a lid over the vessel as a way to prevent the coffee from cooling too quickly. Having a lid on the cup prevent spills. It also keeps insects from flying into the cup if spending time outdoors drinking coffee.

As you can see, many things make a good refillable coffee cup great. Each offers you a certain level of safety and convenience that a paper coffee cup doesn’t deliver. By choosing to make coffee at home and carry it to work in a reusable coffee cup, you’re able to cut back on a lot of the waste that you would generate by consuming hot beverages regularly.

A microwave is a fast way to reheat food and beverages. It does, however, require a degree of knowledge to operate safely. Some items do not belong in microwaves, such as paper coffee cups and aluminum foil.
