There are many alternatives to using Styrofoam block packaging and peanuts, which take hundreds of years to degrade and easily become litter. If your product comes packaged in the stuff, write to the company to ask them to switch to packaging that is easily compostable (e.g., compostable peanuts, molded paper, mushroom packaging) or easily recyclable (e.g., cardboard, air pillows).
BI Zero Waste teams up with Bay Hay and Feed to hold weekend collection events twice a year, generally in January and July (moved to September this year). Check the events calendar for the dates of the next collection. You are responsible for preparing your Styro before bringing (clean, dry, no tape or stickers). See this page for what is acceptable and what isn’t.
Kitsap Solid Waste holds a Saturday collection twice a year, generally in July (canceled this year) and December.
