They’re psyched about trash in Horsham. Especially as it relates to the 10th birthday of the Jarrett Nature Center April 21, and a guest appearance by Tom Szaky a guy who turns garbage, literally, into gold. The Hatboro-Horsham Educational Foundation is hosting a visit by the 30-year-old eco-entrepreneur, CEO and co-founder of the Trenton, N.J.-based TerraCycle Inc., producer of the world's first product made from and packaged in waste. Szaky will address visitors at 10 a.m. about upcycling, recycling, solutions to dealing with waste besides landfills and burning, the creative and design process at TerraCycle, and its plans for future products. A question-and-answer session will follow. Free family-friendly activities are planned from 9 a.m. to noon at the Jarrett Nature Center, Hatboro-Horsham School District's "outdoor classroom" on 13 acres. There are woodlands, a meadow, a pond and wetlands. The nature center is located between Hatboro-Horsham High School and Simmons Elementary School (diagonally across from the football stadium) just off Hatters Way in Horsham.
