ICAW 2021
May 2 – 8, 2021

Thank you for your interest in International Compost Awareness Week (ICAW) 2021

International Compost Awareness Week (ICAW) is the largest and most comprehensive education initiative of the compost industry. It is celebrated nationwide and in other countries each year during the first full week of May. Started in Canada in 1995, ICAW has continued to grow as more people, businesses, municipalities, schools and organizations are recognizing the importance of composting and the long-term benefits from organics recycling. The goal of the program is to raise the awareness of the public regarding the benefits of using compost. The program includes a poster contest in the fall and activities and events held during the week in May.

Throughout the week of ICAW, community and business events are held to encourage and celebrate composting. All types of composting – from backyard to large-scale are promoted. Events include tours of compost facilities, school gardening programs, compost workshops, lectures by a well-known gardening expert, compost give-away days, state and city proclamations, visiting with legislators, and lots of lots of sharing information on social media.

Each year, a theme is chosen. The theme for 2021 in the United States is Grow, Eat…COMPOST…Repeat.  The theme is used for the Poster Contest, which encourages artists throughout the world to create a design sharing the importance of composting and compost use. There is also a video contest for children in 4th – 8th grade (ages 10 and up).

The ICAW 2021 theme is based on the circular movement of the organics recycling process flowing from farm to table to farm again. This circular process turns recycled organic materials into compost which creates healthy soils leading to more nutrient dense fruits and vegetables, with those scraps going back to being composted and the process starts again. Compost adds carbon back into the soil, promotes erosion control and closes the loop by avoiding the loss of valuable organic resources. From on-farm composting, large-scale commercial composting facilities to community composting and composting in backyards, this amazing resource provides an ecologically responsible option for managing our organic materials. This year’s ICAW 2021 theme, Grow, Eat…COMPOST…Repeat, empowers us to recognize and promote the importance of composting and the use of compost in growing healthier food, supporting healthier soils and, ultimately, creating a more just and sustainable world.
