“…The USA is one of many countries that produced very limited amounts of coffee, with production of 2270 tonnes in Hawaii and California in 2021 [ 20 , 21 ]. Post-consumption coffee waste includes SCG as well as increased slowly decaying microplastics [ 22 ] and nanoplastics [ 23 ] in the environment, with unknown long-term health risks. As an example, Planet Ark in 2016 in Sydney estimated that Australians use 1 billion coffee cups each year, producing 60,000 tonnes of plastic waste [ 24 ].…”

Coffee is a popular and widely consumed beverage worldwide, with epidemiological studies showing reduced risk of cardiovascular disease, cancers and non-alcoholic fatty liver disease. However, few studies have investigated the health effects of the post-brewing coffee product, spent coffee grounds (SCG), from either hot- or cold-brew coffee. SCG from hot-brew coffee improved metabolic parameters in rats with diet-induced metabolic syndrome and improved gut microbiome in these rats and in humans; further, SCG reduced energy consumption in humans. SCG contains similar bioactive compounds as the beverage including caffeine, chlorogenic acids, trigonelline, polyphenols and melanoidins, with established health benefits and safety for human consumption. Further, SCG utilisation could reduce the estimated 6–8 million tonnes of waste each year worldwide from production of coffee as a beverage. In this article, we explore SCG as a major by-product of coffee production and consumption, together with the potential economic impacts of health and non-health applications of SCG. The known bioactive compounds present in hot- and cold-brew coffee and SCG show potential effects in cardiovascular disease, cancer, liver disease and metabolic disorders. Based on these potential health benefits of SCG, it is expected that foods including SCG may moderate chronic human disease while reducing the environmental impact of waste otherwise dumped in landfill.

This article presents the first-ever findings on the release of MPs (microplastics) from tea bags containing tea leaves into tea infusions in Türkiye. The study aimed to investigate the possible distribution and abundance of MPs in cup of tea bags and teapot tea bags of fifteen packaged tea brands in Türkiye using ATF/FTIR analysis. The results showed that MPs were found in all the analyzed tea brands. Surprisingly, the highest particle number was observed in the dry tea samples (removed from tea bags) belonging to all brands. Brands A and O had the highest abundance of MPs. All MP particles identified were fiber in shape, and four colors were identified, with a predominance of navy blue. Polyethylene terephthalate (PET) was the most abundant polymer type. The size of MPs varied from 33.65 μm to 1680.20 μm. The daily MP exposure by tea intake was analyzed for male and female groups, and the dietary exposure for males was greater than that for females. According to the MP contamination factor values, a wide variety of MP contamination levels were determined, with a predominance of significant and very high levels of contamination. The mean polymer risk index was determined to be 10.80, indicating a low level of risk. Additionally, this study also provides information on the potential health effects of these harmful MPs. Considering that consuming tea is a significant way for individuals to come into contact with MPs, tea prepared with tea leaves packaged in tea bags could potentially have adverse effects on the health of consumers.
