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…]

Paper straws once swept through the food service industry in the name of environmental protection, yet they have been widely criticized for their poor mouthfeel and tendency to degrade in the mouth, and are now gradually exiting the market. Their replacement, PLA straws, are made from plant starch, are fully biodegradable, and withstand temperatures ranging from cold to hot drinks, but they have a short shelf life and relatively high cost. Meanwhile, research teams have developed edible bacterial cellulose-based straws that completely decompose within 60 days when buried in soil. From paper straws to PLA to coconut jelly straws, behind the iteration of eco-friendly straws lies a trade-off among cost, experience, and degradation performance. This article reviews the current state of paper straw production being discontinued, the market prospects for PLA straws, and the research progress on new edible straws, and includes Front Street Coffee's specialty bean news.

In the coffee industry chain, silver skin is often overlooked as a roasting by-product. However, Japan's Ito En and Tully's Coffee have teamed up to transform this thin protective layer into water-resistant straws.

Although these products are currently limited to some stores in Japan, silver skin-blended paper has already taken an eco-friendly step in reducing pulp usage. This article will guide you through the transformation of coffee silver skin from waste to practical accessories, and revisit coffee grounds recycling cases such as Starbucks' ground coffee straws, exploring the possibility of fully utilizing the entire coffee fruit.

In 2021, Coca-Cola carried out a new round of visual packaging upgrades for its product line, with Coca-Cola, Diet Coke, and Coke Zero all receiving more minimalist new looks. This redesign continues the "One Brand" strategy introduced in 2015.
