International Compost Awareness Week 2017

International Compost Awareness Week (ICAW) is the largest and most comprehensive education initiative of the compost industry. The goal of the program is to raise awareness around the benefits of using compost to improve or maintain high quality soil, to grow healthy plants, reduce the use of fertilizers and pesticides, improve water quality and protect the environment.

RecycleSmart is partnering with the UC Master Gardeners of Contra Costa County to plan activities throughout the week!

ICAW is a world-wide education initiative that started in Canada in 1995. The US Composting Council oversees National activities.


At each event, RecycleSmart residents will have the opportunity to enter a FREE raffle - up to six chances to win!

Prize 1: Soilsaver Compost Bin, compost thermometer, compost aerator, ceramic kitchen food scraps container.

Prize 2: Wriggly Wranch Worm Bin, 1-pound composting worms, (The Worm Farm), ceramic kitchen food scraps container.
