Available today in many shapes and forms, plastics have become part of our daily life, however, their popularity and almost endless applications presents a series of challenges for the recycling industry.
We now use about 20 times more plastic than we have done it 50 years ago and some post-consumer products contain less than 20 different types of plastics This widespread use of all kinds of plastic, it is difficult to gather enough amounts important for certain types of make viable recycling At the same time, each variety has a special molecular composition and, consequently, a different recycling process must be used identification and separation technologies are crucial for the recycling of efficient and effective plastic.
Recycling reduces energy consumption, pollution of air and water, but also the amount of plastic that are found in plastics landfills are polymers composed mainly of oil, so the recycling industry plays an important role in preserving this vital natural resource.
The recycling of plastics require a chemical series and mechanical procedures.
This sort critical part of the process may be performed manually or mechanically.
Shredding and compaction If necessary, the sorted plastics are shredded into small pieces and bailed to facilitate handling and transport.
Washing debris passes through various mechanical processes to remove dirt and dust is then washed and ground to small flakes flotation tanks are also used to separate plastics contaminants.
melting plastic is either melted or formed into granules or pellets.
Reactivation The pellets are shipped to manufacturing plants where they are processed into new products.
The biggest problem with plastic recycling is that it is a lot of work and it is because it is difficult to automate the digital codes sorting process are used to indicate different types of plastic new mechanical sorting processes spectrometry are being developed and implemented to increase plastic recycling capacity and efficiency.
The containers are usually made from a single type of plastic, which makes them relatively easy to sort, however, mobile phones for example, generally have different components made from different types of plastic new programs of research and development are set up to improve dissassembling technologies and increase the rate of recovery and recycling of plastic products.
Unlike metals, recycling usually affects the physical properties of plastics to some extent, which makes it difficult to recover large amounts of some types of plastic used in the same applications that were originally produced for thank you for intensive research and the technological progress made by recycling companies, recycled plastic can be used in almost as many applications and products than those using virgin materials.
These are just a few products that can be manufactured from recycled plastic.
A ton of recycled plastic saves 5.774 kWh of energy 16 barrels 3 2604 liters of oil, 98 million Btu's of energy, and 22 cubic meters of discharge.
There is a 80 to 90 reduce energy consumption by producing recycled plastic from the plastic production from oil and gas from virgin materials.
Recycling a single plastic bottle can retain sufficient energy to ignite a 60-watt bulb for six hours.
Recycling 5 PET plastic bottles produced enough fiber to a t-shirt.
The recycling 100 million cell phones saves enough energy to power more than 194,000 US homes for a year.
World trade is recyclable plastics is estimated at 5 billion a year and is estimated to represent a total of 12 million tonnes.
EUROPE March 21 recycled plastic waste in 2008 about representing 5 3 million tons.
A recent study shows that if all plastic landfill waste is recycled or recovered for energy, and 7 of the European quota CARBON REDUCING GAS will be fulfilled.
