From Waste to Wonder: Exploring the Potential of Coffee Byproducts

The Potential of Coffee Byproducts: Finding Value in Waste

Coffee is more than just a beverage. It’s a global industry, a cultural staple, and a source of inspiration for millions of people around the world.

The coffee industry generates a staggering amount of waste, from the discarded cherry husks to the leftover grounds. However, these byproducts are not just waste. They are valuable resources with the potential to create new products and add extra value to the coffee supply chain. In this article, we will explore some promising coffee byproducts and their potential.

What is Cascara?

Cascara is a byproduct of coffee production that comes from the dried skin and pulp of the coffee cherry. Coffee cherries are the fruit that contains the coffee beans. Traditionally, cascara has been seen as waste material, and it was usually discarded or used as fertilizer.

However, in the last few years, cascara has gained attention as an ingredient with a lot of potential. Cascara is high in antioxidants and has many possible uses.

Legalization of Cascara

Despite its ancient use in some cultures, cascara has been deemed a novel food in Europe, which means it needs to undergo a lengthy authorization process before it can be marketed as such. The European Union sounds its food stamp only after the food safety of a product has been assessed in detail.

While this process is important in ensuring food safety, it can also be complicated and bureaucratic, meaning that it can take years for a food item to be authorized.

Cascara Tea

One of the most common uses of cascara is to brew tea. The tea made from cascara is also called “Qishr.” It has a sweet and fruity flavor with a touch of hibiscus.

The caffeine content in cascara tea is lower than in regular coffee, so it’s a great alternative for people who want to reduce their caffeine intake. Brewed cascara can be enjoyed alone or mixed with other ingredients, like lemon or mint, to add flavor.

Other Promising Coffee Byproducts

Coffee is not just a beverage; it’s also a source of valuable byproducts. These byproducts can be used for a range of purposes, from composting to food and drink.

Here are some other coffee byproducts with potential:

Importance of Coffee Byproducts

The coffee industry has long been recognized for its sustainability and the value of its byproducts. Coffee byproducts are packed with beneficial nutrients and antioxidants that can be harnessed to create products ranging from organic fertilizers to beauty treatments.

Silverskin or Chaff

Silverskin, also known as chaff, is the papery skin that covers the coffee bean as it roasts. It’s usually considered waste and often removed and discarded, but it has a surprisingly high protein content and can be used in a variety of baked goods, from bread to cookies.

Coffee Leaves

Coffee leaves have been used traditionally in some cultures to brew tea for centuries. The leaves of the coffee plant are also high in antioxidants and have a delicate, almost herbaceous flavor.

However, the use of coffee leaves in food and drink is still limited and legally restricted in some countries.


In conclusion, coffee is not just a beverage; it’s a source of waste with untapped potential. By exploring the byproducts of the coffee industry, we can find new uses for previously discarded materials and add value to the entire coffee supply chain.

Cascara, silverskin, and coffee leaves are just some of the byproducts that could be key players in the future of food and drink. It’s time we started thinking of coffee as more than a cup of java and instead, explored its full range of possibilities- from the cherry to the leaf.

Coffee Expert’s Insights: Harnessing the Potential of Coffee Byproducts for Sustainable Living

Coffee is not just a beverage, and its value extends far beyond the cup. The coffee plant produces a wealth of byproducts that have long been considered waste.

However, more and more experts are starting to realize the potential of these byproducts and exploring new ways to use them. In this article, we’ll delve into the insights of Dr. Steffen Schwarz, a German coffee expert, to learn more about how to harness the potential of coffee byproducts for sustainable living.

Interview with Dr. Steffen Schwarz

Dr. Steffen Schwarz is a German coffee expert, researcher, and the founder of Coffee Consulate, an organization dedicated to the promotion of specialty coffee. When asked about the potential of coffee byproducts, Dr. Schwarz replied, “What we need to do is explore the untapped potential of these byproducts, and turn them into something valuable to sustain life. It’s about using everything, right down to the last cherry.”

Coffee Plant Byproducts’ Potential

Dr. Schwarz recommends exploring ways to use coffee byproducts like purees and syrups in recipes, as well as creating coffee spirits and using coffee grounds to create plant-based proteins. According to Dr. Schwarz, coffee byproducts have enormous potential in the food and beverage industry.

For example, coffee cherry pulp could be used to make purees or syrups for drinks or desserts. It could also be used as a source of fermentable sugars to create probiotics.

Meanwhile, coffee spirits like coffee liqueurs and cold brew coffee could be used as ingredients in cocktails and cooking, or enjoyed on their own. Plant-based protein is also another exciting avenue.

Coffee beans are high in protein, and the leftover coffee grounds after brewing could be used to create a protein-rich food additive. “We can use these byproducts to produce a range of food products that are delicious, high in nutrients, sustainable, and healthy. For example, using coffee grounds to make plant protein powders could be another way to feed the world,” says Dr. Schwarz.

Sustainability in the Coffee Industry

Sustainability is an essential aspect of the coffee industry. This includes ensuring that coffee production is environmentally and socially responsible and sustainable for generations to come.

One area where sustainability is gaining more attention is in the harvesting process. Most coffee farmers currently use a method called “strip picking”, where whole branches are harvested at once, stripping the trees of both ripe and unripe cherries.

This method is less efficient in terms of yield, and it also has an ecological impact. However, there is a new way of harvesting coffee: selective picking, which involves only picking the ripe coffee cherries off the branch.

This method is more labor-intensive, but it yields a higher-quality product that is more valuable on the market. Selective picking also has significant environmental benefits.

By leaving the unripe cherries on the tree, the tree is better able to maintain its overall health and is less vulnerable to pests and diseases. This translates to higher yields and a more sustainable harvest.

According to Dr. Schwarz, “We need to work with farmers to educate them about the benefits of selective picking and invest in equipment like selective harvesters to help streamline the process. By doing so, we can ensure that the coffee supply chain is sustainable for generations.”


Coffee is so much more than a cup of java. The coffee plant is a source of valuable resources that can be used for a range of purposes, from food and drink additives to plant-based protein and more.

By exploring the untapped potential of coffee byproducts, we can create a more sustainable future and develop innovative products that are clean, healthy, and nutritious. As Dr. Schwarz has shown, the possibilities for coffee byproducts are endless, and we are just beginning to scratch the surface of their potential.

In conclusion, coffee byproducts have the potential to be harnessed for sustainable living and a more efficient coffee supply chain. Through innovative uses such as creating purees, syrups, and plant-based protein to selective picking this can also make a positive impact on the environment.

Experts like Dr. Steffen Schwarz advise us to explore the untapped potential of coffee byproducts and make them available for food and drink consumption, making it an essential element for clean and nutritional food. The future of coffee is not only bright but sustainable.
