In 2021, recycle every jugOur recycling program makes it easier for Canadian farmers to be responsible stewards of their land for present and future generations. By taking empty containers (jugs, and empty ag-bags) to nearby collection sites, farmers proudly contribute to a sustainable community and environment. When recycling jugs, every one counts.Ask ag-retailers for a collection bag, fill it with rinsed, empty jugs and return to a collection site.Scan toFind a collection [email protected] more! near you at cleanfarms.ca @cleanfarmsGiven the current COVID-19 situation, please call ahead to collection sites for instructions on delivering empties.36 SPUDSMART.COM SPRING 2021'
