There is a lot of talk around the word plastic, but what exactly does it mean? Plastic is a generic term for a number of different synthetic or semi-natural materials which make use of polymers as an active ingredient. Their plasticity allows them to be extruded, moulded or pressed into various flat structures of different shapes. Some popular examples of materials made out of plastic include:
While the vast majority of plastics are produced within the environment (at least in the production stage), there is also a large amount of plastic waste which can not be used or recycled. This is one of the most significant problems facing our modern society. As plastic is non-biodegradable, it piles up and forms a major problem in the landfills all over the country. This is why plastics recycling is becoming increasingly important – making use of plastics recyclability and the methods and equipment used to process them can reduce the amount of plastic waste that ends up in our landfills and the number of tons of trash that are dumped into the environment every year binh nhua 30 lit.
One very useful type of plastic is polystyrene. This is a product of the crude oil industry and is usually blended with propylene glycol to make it less sticky. However, the most common use of polystyrene is as packaging for food, particularly for soft drinks, although it is also found in food wrappers and some snack packaging. This is because polystyrene is low-density and has a relatively short ‘coming-out’ time when sprayed onto a surface – it hardens immediately. It is also resistant to acids, fats and other chemicals.
Another commonly recycled plastic number is PVC. This is a product of the plastic manufacturing process but it is also found in things such as T-shirts and disposable cameras. PVC can be made into shapes using a PVC extrusion machine, although pre-molded products are more common. PVC is resistant to petroleum-based solvents but is not as robust as polystyrene. It does not soften easily and is prone to bursting if subjected to high levels of force.
There are many different types of plastics available to us in recycling bins. Take the blue can (also known as milk jugs) which are popular because they are quite decorative. You might also want to consider the black can because it will not explode and is highly unlikely to contain a hazardous chemical. The best way to recycle them is to put them in your local garbage company bin. You should take care to take empty bottles and cans to this particular kind of recycling facility, so that you do not end up filling up your own trashcan. Plastic is not the only material that can be recycled; in fact it is more likely that you would be able to recycle the following materials if you knew where to look: glass, tin, plastic, paper and aluminum can all be recycled using the same processes.
Another way of recycling your household’s plastic is to create CD (can-conditioned) bottles. These are similar to the plastic that can be recycled but have been specially treated to keep them safe from UV light and bacteria. They are extremely popular with campers and people who live in mobile homes because they are easy to carry. These are recycled using polyolefin and then placed in steel drums and then put into a landfill. They are great for seniors who need to store a lot of beverages or people who live in small spaces.
