8 Things To Know About Sustainable Cups

When it comes to drinking coffee and other hot beverages, you’ve probably got a favorite mug on your desk. Maybe it’s one of those tall Styrofoam cups from your old favorite coffee shop or maybe it’s a fancy ceramic mug that someone gave you as a gift. Either way, what you might not know is that this seemingly innocuous object can be harmful to the environment!

Things you need to know about Sustainable Cups

What Is A Sustainable Cup?

A sustainable cup is a reusable cup made from renewable resources. The most common types of sustainable cups are made from bamboo, corn, and sugarcane. These materials can either be biodegradable or recyclable depending on how they were manufactured.

A disposable cup may look like it’s made out of paper, but it often contains plastic which cannot be recycled in most cities. On the other hand, a reusable bamboo cup can easily be composted at home!

They’re Compostable

If you’re already a home composting enthusiast, you’re familiar with the process of breaking down food scraps into nutrient-rich fertilizer for your garden. Compostable cups are made from plant-based materials. They break down in a home composting bin and return nutrients to the soil, making them an environmentally friendly option when it comes to disposables.

They’re Made From Plants

When you think of sustainable cups, you probably think of corn-based plastics or biodegradable composites. But did you know that the most sustainable material for your cups is made out of plants?

Plants are renewable, which means we can continue to grow them without running out any time soon. In addition to being renewable, plants are biodegradable and compostable. That makes them eco-friendly in every way!

They’re Certified Home Compostable

You can feel good about using these cups because they’re certified home compostable. This means that the cup will break down into organic matter in a home composter, but not in a commercial facility. If you have access to a backyard composter or worm bin, feel free to throw your cups away there!

You Can Put Cold Drinks In Them

While the cup you choose won’t make a huge difference in the world, it is important to understand that there are options out there. For example, you can put cold drinks in your sustainable cup. If you’re thinking about getting one for this purpose, it may be helpful to know how to do so. You might also want to know how hot drinks work with our cups or what happens when we mix hot and cold together!

We’ll show you how easy it is:

  • Fill up with water at room temperature (or if you don’t have access to tap water, use some bottled water).
  • Put on the lid while holding both sides of the handle firmly in place with your fingers until they click into place (this will prevent leaks).

If this feels like too much work or if your lid doesn’t fit quite right, try another mug—some mugs have lids that are not compatible with others (i.e., they aren’t universal), so make sure yours fits before buying!

They’re Better For The Ocean

These cups are made from recycled paperboard and come with a bamboo lid. The lid is also compostable, so it breaks down quickly when thrown in the trash. Plus, you can use these cups to add some greenery to your day without worrying about them ending up in the ocean or polluting the land after they’re used up.

They’re 100% biodegradable and recyclable, so you can return them to Mother Earth safely once they become useless (or if you just don’t want them anymore). They’re all-around better for our environment!

You Can Heat Them In The Microwave

You can heat these cups in the microwave, oven, on the stovetop, or by using a kettle. You can also heat them with a hot water bottle. And if you have one of those steam cleaners that are all the rage these days (or even if you don’t), you can use that to warm up your cup too!

They’re Great For Hot Or Cold Beverages

You can use these cups for hot or cold beverages, whether you are drinking coffee, tea, water, or smoothies. They’re also great for soups and stews. Because they’re made from plant-based materials, they are compostable and you can wash them in the dishwasher. These cups are microwave safe (though some people prefer not to). 

You don’t have to worry about BPA leaching into your drink when microwaving them because they’re made from plant-based materials! The best part is that once you finish drinking out of this cup at home, there’s no need to throw it away! You can easily rinse out your cup clean with warm water and re-use it again later on down the road!

Frequently Asked Questions

Are your sustainable reusable cups dishwasher safe?

You can wash your reusable cups in the dishwasher! But you shouldn’t put them in the same place as your glassware, as they may not survive an accidental impact with a ceramic plate. And while we’re on the topic of impacts: don’t use a high heat setting or any dry cycle that might cause dishes to bang around.

You should also never put them through a sanitized cycle—that’s what they’re made for. Similarly, don’t run them through a non-dairy cycle (like “China”) or a china cycle. If you have any doubts about whether something is safe for your sustainable cups, just ask us and we’ll be happy to help!

How do I wash my cup?

Wash your cup by hand with hot soapy water. Rinse well and dry with a towel or let it air-dry on its own if you don’t have time to wait for it to dry completely.

If you’re washing your cup in the dishwasher, always set it to the “gentle” cycle and try not to overload it with dishes–this will help reduce wear on both your other dishes as well as your Hydro Flask bottle!

Are sustainable cups microwave safe?

It is absolutely safe to heat sustainable cups in the microwave. Many people prefer microwaving their hot drinks over using a stove or kettle because it’s easy and convenient. However, there are some things you should keep in mind when heating your cup on high for longer than 20 seconds.

First of all, remember that the lid will get very hot as well. If you’re using a paper cup with a waxed lining on top, make sure to let it cool down before removing the lid! Also, be careful not to overfill your cup—if there’s too much liquid in there when you go to heat it, then it may overflow and leave your kitchen looking like a crime scene after an episode of Murder She Wrote (don’t ask us how we know).


At the end of the day, we all want to be more sustainable and use less plastic. So if you’re looking for a green alternative to disposable cups, feel free to choose from any of the options above. The key is to just get started!
