On the terrace or at home, in winter or summer, coffee is one of the drinks of choice in many people's daily lives. This is a habit that is possible to have sustainably: make a coffee or your favorite drink and know everything about this drink.

Do you know all the benefits and what types of coffee there are? In addition to these answers, we will show you 4 ways to recycle coffee grounds in a simple and, of course, sustainable way.

Benefits of coffee

There are several studies and news about the benefits of coffee for our lives, but what are they? The benefits of coffee for health and well-being are:

  • Reduction of the feeling of fatigue;
  • Increased levels of attention;
  • Improved memory and reasoning;
  • May protect against certain diseases (colon cancer, type 2 diabetes, liver cirrhosis, hepatocellular carcinoma and depression)

All these advantages are related to the caffeine and antioxidant compounds present in coffee. However, the APN argues that “more scientific research is needed in this area to understand the mechanisms underlying these protective effects of coffee.”

Nutritional composition

Although it depends on several factors, such as the variability of the plant or the preparation method, the APN states that, on average, the value is 74.5mg of caffeine per cup of espresso.

The recommended average daily consumption is 2 to 3 coffees per day for healthy adults (around 400mg), and the APN highlights that each person's susceptibility to caffeine must be respected. For women who intend to become pregnant, are pregnant or breastfeeding, the value drops to 200mg per day.

Different types of coffee

According to Gunter, cited by BBC Future , the way coffee is prepared, whether through beans or instant powder, does not seem to change the association with better health. In other words, through his study in 10 European countries, Gunter states that it is not about the type of coffee but rather the consumption of coffee itself.

With several types and different flavors, coffee production has increased from year to year, as you can see in the following graph from the Food and Agriculture Organization of the United Nations (FAO).

If you use this type of coffee, you can (and should) recycle the coffee capsules correctly: if they are made of plastic and metal, they should go to the undifferentiated recycling bin in accordance with Sociedade Ponto Verde. However, if the Brand has collection points, it is recommended that you deliver the capsules to these locations.

You can also reuse the capsules as decorative elements or you can simply reduce this waste with alternative options:

  • Reusable capsules
  • Compostable coffee capsules

Recycle coffee grounds

Coffee grounds can also have a new life after enjoying this hot drink first thing in the morning or after a meal. Let's find out 4 ways to recycle coffee grounds?

Coffee grounds as fertilizer

Coffee grounds in the garden increase minerals in the soil as coffee beans contain important minerals for plant growth such as nitrogen, potassium, phosphorus, among others.

However, it should be used in small quantities because, although nitrogen and acidity are good for plants, caffeine does not have the same effect. This way, adding coffee grounds to plants is possible, but in balanced amounts.

Coffee grounds: composting

If you don't need to use recycled coffee grounds as fertilizer immediately, you can put them in the composter for later use.

Coffee grounds also eliminate odors!

By using a cup with coffee grounds in the fridge you can reduce the more intense odors of some foods as well as odors in shoes, simply by placing a little coffee grounds inside them.

Skin exfoliant

Coffee grounds can be an exfoliant for the skin as it stimulates skin cells.

Now that you know how to recycle coffee grounds, what will be the first option you put into practice?
