What is SB 54?

SB 54 or the Plastic Pollution Prevention and Packing Producer Responsibility Act was signed into law in 2022 in an attempt to shift the environmental responsibility of packaging onto producers rather than consumers.

Here's a little rundown of what this law is going to require:

The law requires that by 2032 we:

📉Cut single-use plastics by 25%

♻️Recycle 65% of single-use plastics

🌎Ensure 100% of single-use packaging and plastic food ware is RECYCLABLE or COMPOSTABLE

This year's fall compost giveaway is scheduled for Saturday, September 5th from 9 AM to 2 PM 🌱 Bring your pick-up trucks, trailers and buckets to get free, organic certified compost from Kompogas SLO!

All of the compost from this facility used to be YOUR food scraps and yard waste! By using your green bin for organic waste instead of tossing it in the trash, you provide facilities like Kompogas with the valuable materials needed to create healthy compost.

Please note that this giveaway is just for residents, and not for commercial business. Help us be respectful! If you bring a pick-up or trailer, make sure to bring a tarp to cover your load so we don't leave compost all over the roadways. For more details, check out Kompogas SLO on Facebook. Happy gardening!
