How is Plastic Recycled?
You took the first step by placing your plastic products into the recycling bin. Have you ever wondered what happens to all your recycling efforts? Will the coke bottle you recycled yesterday get turned into a t-shirt?
The recycling process is actually pretty long winded and complicated! It involves a lot of sorting, cleaning, and melting before it can be reused. Let's get started, shall we?
Most recycling centers use what is known as a single stream recycling system. That is, all recyclable goods including plastic, metal, glass, paper are collected all at once. These different types of recyclable goods must first get sorted.
Unlike recycling glass, metal, and paper which is pretty straight forward, plastics must be further sorted by plastic types (that is PP, PE, ABS, PET, etc…). This is because some plastic types cannot be melted with each other due to differing melting points and properties. If two plastic types are melted together, the resulting mixture is usually weak in structure and will solidify in layers (like oil and water). Therefore, mixed plastic types cannot be efficiently used for product manufacturing.
In fact, most recycling centers only take two types of plastic products, commonly type 1 PET plastic and type 2 HDPE plastic. The plastic numbers are usually found imprinted at the bottom of plastic products. This is the number inside the recycle symbol (three circulating arrows). Before sending any plastic to the recycling center, make sure you do a little research. If you send a recycling facility something they do not handle, it may end up in landfills.
Now that we have the plastic sorted by type, depending on the recycling facility, it may end up being further sorted by colors. Clear, natural, and white colored plastic is always the most desirable because it can be dyed to produce other colored plastics. For example, if you have a load of green plastics, it cannot be changed to blue. If you have a mixed colored lot, it usually gets dyed to produce black plastic products.
As the sorting process is very labor intensive, after the plastic is sorted by type, it is usually packaged and shipped to Asian countries for processing.
The plastic must now be washed to remove any residual sodas or juice. Let's follow how the common coke bottle is cleaned. While the coke bottle itself is made from PET (or PETE), the bottle cap and label is made from a different plastic type, PP or PE. Luckily, both PP and PE has densities less than 1 and will float in water. PET, when placed in water, will sink. When the bottle shreds are placed in a tank of water and mixed around, the plastic floating at the top is PP or PE and is manually removed. The bottom layer is PET and will move onto the next step.
While water takes care of partially cleaning the plastic, it must now be cleaned using a corrosive solution to remove any glues or chemicals. We now have a sorted and cleaned batch of plastic shreds which are placed in large dryers to remove moisture. At this time, the flakes are either sold or transported to another location for production into plastic pellets or nurdles (as pictured above).
Plastic pellets are the raw materials required for product manufacturing. One thing to note is that recycled plastics are never as versatile or "good" once it is reused. Recycled plastics are therefore usually "downcycled" into other products. That is, old milk bottles never get to make new ones, instead they are made into a different product all together such as toys.
Often times, recycled plastic is sold to manufacturers that mix recycled materials with virgin material to produce products. This way, they can ensure the finished product to be high in quality while saving (money) the environment.
About the Author
I'm a plastic trader and processor and have more than 5 years experience working in the plastic recycling business in China.
Recently, I started a new blog, Recycled Plastic dot com, that covers my knowledge and experience in this field.
Recycled Plastic do com covers the latest news, stories, trends, products and resources relating to plastic and plastic recycling. It brings awareness to how plastic waste is endangering and poisoning our environment and steps we can take to reduce, reuse, and recycle. It aims to provide readers with an open forum for discussing these issues.
I hope you will enjoy what I have to write!
Why do you need to use black plastic mulch to grow watermelons?
I was reading this site, http://www.urbanext.uiuc.edu/veggies/watermelon1.html , and it says to put black plastic mulch. Why does it need to be black? Can it be a different colour and be as effective?
I have a clear plastic, would that work?
You don't want to use the clear plastic for sure as this will allow the sunlight through to the surrounding soil and lead to weeds that will compete hard with the watermelons and you want be able to get to them. The reason for the black plastic is a couple of reasons one is to prevent weeds from coming up around your watermelons as the only plant that will get the direct sunlight will be the watermelon through the small hole in which you transplanted the plant. Another reason is that watermelons love heat and black will absorb the rays from the sun and heat the soil under the plastic where the roots of the watermelon is to a higher temp than the soil not covered and the last and one of most important reasons is that watermelons require a lot of moisture when produding their fruit and the ground covered will retain moisture far longer than the soil that isn't. You should however have some way of watering underneath the plastic for best results like the use of trickle irrigation tape or a soaker hose that is placed under the plastice before securing it down with soil. There are other colors of agriculture plastic mulches that may work like green, red and white but they are generally more expensive and are these different colors for other reasons as with white is for growing cooler season crops but still benefit from weed control and moisture retention of the soil but being white it want heat the soil as much as with black. I hope this helps you understand a little more as to why the recommend black plastic and for sure don't use the clear as it will cause some serious issues.
