Join ECOSLO and IWMA at at for Question the Cup, an educational workshop exploring what compostable plastics are made from, how they're supposed to break down, and why they aren't accepted in San Luis Obispo County's green bins.
Nia Starr, the Sustainability Coordinator at ECOSLO, will be breaking down the differences between conventional plastics, bioplastics, and compostable plastics. Ashley Kuder from the SLO County Integrated Waste Management Authority will explain how our local organics processing system works, what actually belongs in your green bin, and why compostable plastics can't be processed locally.
