Summary: Styrofoam, a kind of non-degradable "white pollution" with a low density of only about 20kg per cubic meter, will pollute the environment when deserted in landfill, or in another case, will gain its rebirth after Styrofoam recycling and serve our life as a new source. In the following introductions, a quick guide of four steps will give you a better understanding of styrofoam recycling.
Just as its name implies, Styrofoam Collection is to collect foam #6 waste from all different resources back to the recycling center where it can be compacted. You can leave your waste Styrofoam in the designated sites of the recycling center, and fit their guidelines as it is a mass collection. Usually, the recycling center only accepts white and clean Styrofoam for recycling, so you should filter out any non-white ones, take off any tape or stickers. After that, all you have to do is wait for their monthly or quarterly service on call.
After finished collection, the recycling center will move on to the next step to compacting when a certain amount of waste Styrofoam is accumulated. Of course, this process is based on the fact that they have such reduction machines like foam densifier, or in other words, whoever has the machine can handle it. The wide significance of Styrofoam Compacting is to achieve volume reduction to pave the way for storage, transportation, granulation and reusing. Disposed by a foam reduction machine, cold compacted or hot melted, the loose and bulky Styrofoam can be tight and solid. Moreover, the compacted Styrofoam will be easier to granulate than the loose one, and the granulation efficiency will be fairly higher.
The recyclers themselves or foam end users often purchase back the compacted Styrofoam blocks and ingots, regenerate and turn into pellets with granulation process, a most widely used technique for manufacturing materials for tablet in pharmaceutical industry. The methods, which include the granule formation, are microencapsulation, multi particulate system for modified release mechanism etc. Styrofoam granulation technique involves addition of liquid binders in aqueous foam base. During Styrofoam granulation binders in aqueous form are added.
Rebirth Of Styrofoam
Through a perfect granulation process, the Styrofoam pellets are shipped to manufacturers where the Styrofoam can be made into a number of items we use every day in and around our homes. For example, the picture frames, interior moulding, pony packs, pens, rulers, foam insulation and foam packaging, etc. What an amazing shift that these daily necessities are made of Styrofoam.
