THRIFT SPOTLIGHT!

Let's highlight reuse and upcycle projects!

Here's 's Nicole who picked up a broken espresso machine that just needed a little love. She cleaned it up, sourced a replacement part, and now has upcycled a high-end, fully functioning espresso machine valued at $1,200!

This is a great example of what a little upcycling can do!

♻️Ever wonder where your recycling actually goes?

Here's the breakdown:

➡️You throw recycling into the blue bin.

➡️Recyclables are collected curbside by your waste hauler.

➡️The recycling goes to our MRF (Materials Recovery Facility).

➡️At the MRF the recycling gets sorted by type, then compacted and packaged into bales.

➡️Bales of recyclables are sold and transported to recycling processing facilities.

➡️Recycling is processed and made into items such as plastic bottles, milk jugs, paper, fiberglass, and even steel products!

Compostable plastic belongs in the green bin? Think again.

🚫Compostable foodware and bags can be deceiving:

Most compostable cups, utensils, and bags don't break down in the facilities that process our organic waste. Or these items are mistaken for regular plastic and removed for contamination.

✅Help keep our compost clean:

Dispose of compostable foodware and bags in the trash, not the green bin. Or ditch the compostable plastic all together and opt for reusable tupperware, bags, and utensils!

California Bans "Sell By" Food Labels ♻️🌿

Help reduce food waste by understanding what food labels actually mean:

Food labels can often be confusing, so here's a simple guide:

🗓️"Best if Used By" ➡️ Food is at its best quality before this date! Plan around it and find ways to use ingredients or food prior to this date.

🧀"Use By" ➡️ Recommended date for peak quality. Eat or freeze food before this date.

🚫"Sell By" ➡️ Intended for retailers to sell product by. California is phasing this label out to reduce unnecessary food waste.

By standardizing food labels, California is making an effort to reduce edible, unexpired food out of landfills.

Food waste happens, but a few small habits can help keep good food from going to waste.

Before tossing extra produce or leftovers, try using them in a new way:

🥕 Save veggie scraps for homemade stock
🍓 Turn extra fruit into jam, smoothies, or baked goods
🥒 Pickle leftover vegetables
🍋 Use citrus peels for a simple DIY cleaner
🍽️ Turn leftovers into an easy lunch or dinner

And when food can’t be eaten, place food scraps in the green bin.

This includes fruit and vegetable scraps, bread, cooked food, meat, bones, shells, and food-soiled paper.
