We use a lot of plastic packaging every day. What do you do with a shampoo bottle once you've finished using it? We throw it away. But we'd rather recycle it to make new plastic. However, the quality requirements for plastic are high. Shampoo bottles must be attractive and leak-proof, food packaging must be free from toxic substances, and medical materials must be safe. Discarded plastic has also become dirty. It is very difficult to recycle it into new plastic, which means that manufacturers continue to use new, cheap plastic. This is where the SPEX recycling process comes in. We place the contaminated plastic in something akin to a pressure cooker. The good plastic dissolves and the waste is filtered out. The plastic is then dried into a powder. This powder can be used to make high-quality plastic packaging. What used to be thrown away and burned can now be reused.
