The Spark team braved the heat and helped sort waste from move-in weekend! Look at all of these soft plastics we’ve been able to not only divert from going into a landfill, but also divert from contaminating and damaging tradition recycling streams! Huge shout out to Schnucks | Grocery Retailer for accepting and recycling our move-in soft plastics recycling every year!

Dedicated volunteers in our SPARK program sort move in waste behind the scenes. What an effort! So many recyclables!”
