For many decades, the main advantage of expensive coffee machines was their numerous functions. However, consumers are now looking for what these devices lack. Growing concern over microplastics and sustainable development is stimulating the emergence of plastic-free coffee machines and capsules.
Companies that produce coffee and home appliances have released new models and redesigned capsules in recent months. For example, new capsules from Keurig and Lavazza replace traditional plastic cups with compostable coffee tablets. A new machine from Caraway uses regular ground coffee, but unlike standard drip coffee makers, its stainless steel and glass body contains no plastic in the brewing system.
Further research is needed to determine the actual harm caused by microplastics. Nevertheless, according to a survey conducted by the environmental group 5 Gyres in 2025, nine out of ten Americans are concerned about the impact of tiny plastic particles on the planet and the human body, and studies have already shown that capsules release microplastics.
The growing demand for expensive plastic-free equipment and capsules aligns with a broader trend where consumers, after the pandemic, began upgrading their home coffee appliances, noted Peter Giuliano, Senior Research Advisor at the Specialty Coffee Association. He explained that the appeal of this trend is driven by three factors: health concerns due to microplastics, environmental care, and the feeling that metal and glass are perceived as more 'luxurious' than plastic.
New Capsules
In June, Lavazza introduced the Tablì model in the US—a $129 machine that operates exclusively on disposable espresso tablets made from compressed ground coffee. This is a change from their previous capsules, which were made of plastic and aluminum. Lavazza stated in a press release that the tablets are created using a special technology that 'precisely doses, grinds, and compacts coffee into a solid, ready-to-use puck.'
The Italian company announced that Tablì is the 'biggest investment' in the US, as it aims to double revenue to $1 billion by 2029 to challenge the monopoly of Keurig Dr. Pepper in the coffee market. According to Daniele Foti, Vice President of Marketing for Lavazza North America, Tablì targets customers who want an eco-friendly alternative to traditional capsules. She emphasized that 'consumers want to enjoy coffee without the waste that usually accompanies single-serve portions.'
Keurig, which popularized plastic with its K-Cups back in the 1990s, launched a new line of compostable capsules in October with a specially designed Alta machine (the new capsules are not compatible with older models). These capsules, named AltaRounds, have been developed since 2020 in response to changing consumer preferences regarding sustainability and health. Philip Drapau, Senior Vice President of Keurig's Future Coffee Systems division, stated that the new capsules represent a 'significant reduction in plastic compared to our K-Cup capsules.' He added that 'we clearly heard from customers that they want more eco-friendly products, specifically less plastic and plastic waste.' Drapau also noted that 'our data shows that beverage variety, quality, and reduced plastic waste are high priorities for almost all groups.'
Keurig had previously faced criticism for its capsules and agreed in 2022 to pay $10 million to settle a class-action lawsuit alleging the company misled consumers by advertising its plastic K-Cups as recyclable, although Keurig denied any wrongdoing. However, despite the capsules and machine containing less plastic, they are significantly more expensive than a traditional Keurig machine. The Alta set, including glassware and capsules, costs $499.
Melissa Valiant, Director of Communications for 5 Gyres, noted that both Lavazza and Keurig products still use plastic that 'ultimately ends up in landfills, incinerators, or our environment after use, contributing to the growing crisis of plastic pollution on the planet.'
New Machine
Caraway focused its efforts on developing a $495 coffee machine released last month that is entirely made of stainless steel and glass, ensuring that no plastic comes into contact with the ground coffee. Unlike Lavazza and Keurig machines, these devices contain some amount of plastic. According to Caraway CEO Jordan Nathan, creating a plastic-free brewing system was a complex task because the expensive glass and steel components required custom manufacturing.
Nathan told CNN that they had to create the best plastic-free coffee with a fully metal body, yet in a compact size for a countertop with a single rotary dial. Concerns about kitchen plastic and its effect on the endocrine system have been growing in recent years. Nathan referenced a viral article linking black kitchen plastic to alarming levels of toxic antipyretics.
Discussion of this topic has been fueled by social media, influencers, and various scientific studies, prompting parents and other health-conscious individuals to avoid plastic wherever possible—whether in cosmetics, food, or bedding. Other Caraway products, such as cutting boards, have seen significant sales increases over the past three years. Nathan added that coffee is a natural next step because 'you should never heat plastic.'
Demand for the Caraway 10-cup coffee maker was so high that it sold out before January, forcing the company to ramp up production. Meanwhile, Keurig and Lavazza reported similar interest, as both companies' products quickly sold out after the initial release. Nathan concluded that this high interest in capsules and machines signals that the industry will move towards more environmentally friendly alternatives, adding: 'If you are not doing this, you are falling behind where the ball is going.'
