How to recycle or replace your polystyrene blocks and boxes

There are many Styrofoam/polystyrene blocks and boxes in the world which are harmful to our body. So, we should think some ways to effect polystyrene recycling. And, the following ways are useful. 
1. Remove all tape and labels. Boxes must be empty, with no contamination (no ice packs, packing peanuts, paper, etc.). Styrofoam that has tape/labels or contamination is not accepted by the recycling vendor.
2. Collect Styrofoam/polystyrene blocks and boxes in clear plastic bags. Note: large lidded boxes do not need to be bagged.
3. Close full bags securely and label them with your department’s name and box number.
4. Place bags and stack large lidded boxes next to the recycling containers at your building’s loading dock; do not block doors or walkways. This is a self-serve recycling program; custodians are not responsible for transporting the Styrofoam.

We can also finding alternatives.
1. Use biodegradable packing materials. The vast majority of Styrofoam is produced because of packing purposes, padding and securing things for shipping. While it can be difficult to avoid receiving Styrofoam when you make a purchase, you can always cut down on your own use of Styrofoam when sending packages by avoiding the use of loose-fill packing "peanuts" and using other kinds of biodegradable packing materials.
Use newspaper, or other recyclable plastic materials to pad your packages. If it's not super-breakable, there's probably no need for Styrofoam.
Using corn and soy-based packing materials is becoming more and more common. If you work for a business that regularly sells things that require packing protection, consider making the alternative to biodegradable alternatives to Styrofoam.

2. Purchase post-consumer recycled materials. When you're making consumer purchases, try your best to only purchase things packaged in and made from post-consumer recycled materials. It can be difficult to know if something you buy will contain styrofoam included in the packing materials, but if you're buying with an eye for companies that make recycling and reusing a priority, you can be fairly certain that the packaging won't include any.
