Earlier this month, I attended the 13th APacCHRIE (Asia-Pacific Council on Hotel, Restaurant and Institutional Education) Conference in Auckland, New Zealand . I was impressed with the country's effort of minimizing waste. As shown in my discussion on MultiBrief.com , I listed three examples I witnessed during the trip, including: The bio loo (toilet) that collects, stores, and compost human waste. The "Make a Green Choice" program at the Rydges Hotel Auckland . The two-button water-flush system in the city of Auckland. Interested in the pictures I took about the bio loo during this trip? Check out the photo album on my Facebook page .
