This "fighting magic with magic" environmental approach—how exactly is it achieved? [more…]

Bringing your own cup to buy coffee is inherently an eco-friendly gesture, but one consumer ran into an unexpected situation at McDonald's: the staff first poured the drink into a disposable cup, then transferred it into the customer's cup. The store explained that customer containers cannot enter the preparation area due to hygiene regulations. The incident sparked widespread discussion—some understood McDonald's food safety considerations, while others felt that using an extra plastic cup defeats the original eco-friendly purpose.

Bringing your own cup to buy drinks at coffee shops has become an eco-friendly habit for some consumers, and chain brands such as Starbucks and Manner have long offered BYO cup discounts to encourage reducing single-use cup usage. However, in reality, it seems that not many people truly stick to bringing their own cups, and the tables in coffee shops are still dominated by takeaway cups. Why are consumers not buying into BYO cup discounts? Some value saving money but give up because the discounts cannot be stacked; some pursue efficiency and feel that bringing their own cup actually wastes time; others encounter troubles such as capacity mismatch, forgetting to bring the cup, or the cup having an odor. Although bringing your own cup causes many inconveniences, for long-term coffee drinkers, the money saved can buy a few more cups, and some even pass off disposable cups as their own, leaving baristas not knowing whether to laugh or cry. Front Street Coffee reminds us that the environmental friendliness and cost savings of bringing your own cup still need to find a balance with convenience. [more…]

Starbucks has been exploring ways to reduce single-use cup usage in recent years, from deposit cups in the South Korean market to cup borrowing programs in Europe and the US, but none have achieved the expected results. Now Starbucks has launched Plan C—introducing dedicated cup-washing machines in stores, where customers can wash their cups themselves after finishing their coffee and take them away, though a deposit is still required. The program will first be tested at Arizona State University and select stores in Hawaii. Meanwhile, Starbucks mainland China has fully switched to paper straws and sippy lids, reducing approximately 200 tons of plastic annually. Whether the environmental path can meet its 2025 targets remains to be seen. [more…]

Around 2.25 billion cups of coffee are consumed worldwide every day, and with that comes a massive amount of spent coffee grounds. Traditional recycling methods—such as deodorizing, exfoliating, or making furniture—often require drying, which actually releases carbon dioxide. Japanese scientist Tetsuji Ishigaki has taken a different approach: using Aspergillus to ferment spent coffee grounds into a paste, then adding cocoa butter to solidify it, creating a ready-to-eat spent-coffee-ground chocolate. This product, called COLEHA, not only contains three times the amino acids of green coffee beans, but its polyphenols and antioxidants also reach 1.6 times those of regular coffee, and it is rich in insoluble fiber that promotes gut health. COLEHA is currently available in limited quantities, with sugar content offered in three versions—0%, 10%, and 40%—each with its own distinctive taste. This article introduces this eco-friendly and innovative spent-coffee-ground utilization technology, along with the flavor and health secrets behind it. [more…]

In recent years, plant-based milks have quickly gained popularity with labels like eco-friendly and healthy, especially oat milk, which has almost become a standard offering in coffee shops. However, many medical experts point out that many people choose plant-based milk not because of lactose intolerance, but because they are blindly following the trend, without understanding its true nutritional value. For this reason, on February 22, the U.S. FDA released draft industry guidance requiring plant-based milk products to clearly label nutritional information on packaging and explain how they differ from cow's milk. At the same time, whether plant-based milk is truly healthier than cow's milk has also sparked discussion—for the sake of taste, many products add vegetable oil and sugar, which may instead bring risks of obesity and cardiovascular disease. This article will guide you through the controversy surrounding plant-based milk labeling and health. [more…]

Coffee grounds, when properly processed, have a variety of uses such as deodorizing and fertilizing, so many customers ask coffee shops for them. Some shops are happy to provide them free of charge. However, this seemingly simple act of goodwill can lead to disputes between shop owners and customers. Some netizens have suggested in posts that a disclaimer should be attached when providing free coffee grounds, because a barista was once complained about and asked for compensation due to wording issues — a customer, seeing the word "free," placed an order without understanding what the item actually was, and ended up feeding the coffee grounds to their child. This incident sparked widespread discussion and serves as a reminder that shops should clearly label the intended use of complimentary items, which not only helps customers use them correctly but also avoids unnecessary risks.

Southern regions have recently been hit by continuous heavy rain, with severe waterlogging on roads in cities like Changsha and Wuhan, making travel difficult for residents and causing significant disruption to street-side shops. In such weather, a cup of coffee is a small comfort that keeps office workers energized and going, yet many customers who chose to pick up their orders at Luckin Coffee stores found that the paper takeaway bags were extremely flimsy in the rain, with the coffee spilling into the rain before they could even take a sip.

This article examines the reasons behind this phenomenon and the voices from all sides. [more…]
