In 2011, ICE Chicago relied on 1 recycling bin for 200 workers; a hybrid system of 4 centers and desk boxes raised recycling to 38% and participation to 85%The U.S. Immigration and Customs Enforcement Chicago Field Office enhanced its recycling program. They established four recycling centers a...
University of Kentucky researchers pressure-cooked bourbon stillage into hydrochar; its supercapacitors stored up to 25 times more energy, while another design retained 96% capacity after 10,000 cyclesChemists at the University of Kentucky have pioneered a remarkable technique to recycle bourbon stillage, converting this distillation wast...
In 2012, Chicago’s Railroad Retirement Board found new life for 3,200 pounds of electronics through reuse and recycling; the effort lifted waste diversion nearly 10%The U.S. Railroad Retirement Board successfully recycled over 3,200 pounds of electronic waste. This achievement was driven by federal prog...
In 1993, Taiwan collected 70% of its trash while recycling virtually none. 33 years later, paid bags, musical trucks and sorting helped drive recycling to 55% nationwideTaiwan’s experience therefore challenges the idea that recycling depends mainly on individual environmental enthusiasm. People certainly ne...
The receipt in your hand looks harmless, but its heat-sensitive coating can contain chemicals that transfer to skin, raising fresh questions about repeated everyday exposureMany receipts are printed on heat-sensitive thermal paper, which contains chemicals like BPA and BPS.
