Benefit of Plastic Recycling and Its Application

If we take the look of plastic use in our lives then plastics came into our lives in the 1950's; however the question is the “safe use of plastics”. Plastics is a part of our everyday living from cups to auto parts. But it soon became damage on our environment.

Plastic is not biodegradable so how to dispose of it was a problem.

To cope up with this question plastic recycling” is considered as one of the advantageous solution. A program for recycling plastic has been started and it has a code which marks disposable as well as recyclable plastic containers.

We all are familiar with the three arrows that make up a triangle. These codes are generally originated on various plastics and within the triangle, there is generally a number. These numbers tell the grade of recycling your plastic container falls into.

Plastic Recycling is a multifaceted process because different types of plastics cannot be mixed before recycling. Plastics of different polymer structures as well as resin composition are identified by using standard codes on the basis of their melting and crushing capacity. 

Plastic materials are identified under a particular code can be mixed and recycled with other plastics of the same code. Plastic materials consist of a few dyes, fillers and additives, which are not easily recyclable.

Advantages of recycling plastic to environment:

Leads to oil conservation: Having oil as important element, plastic recycling saves four barrels of oil. However; the oil prices are soaring day by day, the prices of basic needs of people like food, gas, products and other commodities is also increasing. So, recycling of plastic is preferred as it consumes less oil compared to manufacturing of original plastic materials.

Decrease Discharge of Greenhouse Gas: As the number of steps involved in recycling of plastic is fewer, it consumes less energy and creates less pollution. So, green house gases are less emitted.

Help to conserve energy: Recycling of plastic needs very less energy so in this way it saves twelve thousand BTUs (British Thermal Unit) when one pound of PET bottles are recycled.

Landfills can be recovered: These days, one of the important problems being faced is, there are no places to dump plastic waste as all of them are filled. So, to reduce dumping of plastic waste into landfills then recycling plastic is an effective solution.

If we think about different applications of recycled plastic then polyethylene bin liners, carrier bags, PVC sewer pipes, flooring, window frames, building insulation board, video and compact disc cassette cases, fencing, garden furniture, water butts, garden sheds, composters, seed trays, anoraks, fleeces, fibre filling for sleeping bags and duvets, variety of office accessories and more products are made from recycled plastic.

However, this recycle waste plastic procedure involves more tedious labor for sorting plastic wastes as per the color & type; and more over, as the worth of material is very less, it is not profitable. Though, it is ideal method as 25% of dumping ground can be recovered, if plastic materials are recycled.

With plastics recycling process, we can reduce oil (non-renewable source) consumption, as manufacturing of original plastic involves huge amount of petroleum. As per the study of recycling of plastic, revealed 1.8 tonnes of oil is saved for every one tonne of polythene recycled. Water usage in manufacturing original plastic is 90% more compare the water used in the process of recycle plastic.

So with the above listed point you can see how recycling of plastic is an excellent strategy to guard our environment from pollution as well as to save non-renewable sources.

Basics Information About Plastic

Nowadays, plastic becomes an essential part of our daily life. However, plastic world market is growing very fast as compare to any other market of the world. 
 
The word plastic is derived from the Greek word "plastikos" meaning capable of being shaped or molded, from plastos meaning molded.It refers to their malleability, or plasticity during manufacture, that allows them to be cast, pressed, or extruded into a variety of shapes—such as films, fibers, plates, tubes, bottles, boxes, and much more.

What is plastic?

Plastic is a common name for Polymers: materials made of long strings of carbon and other elements. Each unit in a string is called a monomer, and is a chemical usually derived from oil.

The monomer is made into polymer by chain-linking reactions. This is like making a daisy chain. Instead of flowers, carbon atoms are joined together. The appearance of the daisy chain will be different if you use different coloured flowers, and so will polymers.

There are many different types of plastic, depending on the starting monomer selected, the length of polymer chains, and the type of modifying compounds added. Each plastic has been developed for a special purpose.
There are two main groups of plastics:

1. THERMOPLASTICS soften with heat and harden with cooling.

    * Some typical thermoplastics are: Acrylic (Perspex)
    * Acrylo-nitrile (Nylon)
    * Polyethylene (Polythene)
    * Polypropylene
    * Poly Vinyl Acetate (PVA)
    * Poly Vinyl Chloride (PVC)
    * Polystyrene and ABS
    * PTFE (Teflon)

2. THERMOSETS are cured or hardened by heat.

Some typical thermosets are:

    * Bakelite
    * Epoxy
    * Melamine
    * Polyester
    * Polyurethane

Properties

Plastics are used because they are:

    * Attractive
    * Hard and slippery
    * Soft and rubbery
    * Tough and slippery
    * Flexible
    * Good insulators of heat or electricity
    * Light weight
    * Hygienic
    * Non-rusting
    * Easy to shape and colour
    * Cheap

The tremendous growth of the plastics industry is expected to continue..The factors that have contributed to this growth include the energy efficiency of plastic world market. All studies show that it takes less energy to make a product from plastics than just about any other material.

Steps Of Plastic Recycling Process

Nowadays, plastic becomes an essential part of our daily life. However, plastic world market is growing very fast as compare to any other market of the world so industrialist have to take care that  their new inventions will not affect the planet environment as well as health of human beings. Plastic recycling is the process of collecting certain materials that would otherwise be considered waste — like old metal, paper, wood, or plastic for example — and turning them into new “recycled” products.

The whole plastic recycling process is described by seven steps as described below:

Steps of Plastic Recycling Process

Some plastics for recycling :-

1 - PET or PETE (Polyethylene Terephalate Ethylene)
Light weight, low-priced, and easy to fabricate, Polyethylene Terephalate Ethylene is the most prevalent plastic material in use today. PET is primarily used in beverage bottles, food receptacles, and peanut butter containers. It can be remade into polar fleece, fiber, carpet, etc. The requirement for this plastic among recyclers is relatively strong, but at present, the recycling rate for this material has remained low at 20%.

2 - HDPE (High Density Polyethylene)
High Density Polyethylene is more durable and more impervious to chemical degeneration, this material poses a relatively low chance of spreading chemicals when used as container for food and drinks. It is largely used as containers for everyday household chemicals (shampoos, degreasers, etc.), juice bottles, milk jugs, etc. This can be reused into floor tile, drainage, new HDPE bottles, pipes, etc.

3 - PVC (Polyvinyl Chloride)
PVC has been tagged as a health hazard - it has been noted to typically drain chemicals when used as containers. PVC is mainly used for piping, window cleaner bottles, siding, etc. It has chlorine and will dispense toxins if burned. PVC should not be used in food preparation or food packaging. It can be reprocessed into mudflaps, panels, mats, etc.

4 - LDPE (Low Density Polyethylene ) LDPE is the material present in plastic bags, clothing, furnitures, etc. Resilient and flexible, it is perfect for packaging, insulation, and sealing. LDPE, through many curbside recycling programs, can be reconstituted into cans, compost bins, and landscaping tiles.

5 - PP (Polypropylene)
Polypropylene is most suited for boiling fluid receptacles and is likewise made into brooms, straws, ketchup bottles, etc. PP can be reprocessed into rakes, brooms, trays, etc.

6 - PS (Polystyrene)
PS is the top component for insulation and is used in foam products like expanded polystyrene (EPS), commonly known as styrofoam. It is found in carry-out food containers, meat trays, CD cases. PS contains benzene, a cancer-causing substance and should not be burned. It is reprocessed into insulation, packaging, plant beds, etc.

7 - OTHER (Polycarbonate)
For Plastic Recycling
7 - OTHER signifies materials not belonging to any of the other 6 resin categories. OTHER may also signify a hybrid resin made up of a mishmash of those materials. It is mainly found in children feeding bottles, flak jackets, business signages, five-gallon water jugs, etc. It can be recycled into plastic planks and other tailor-made objects.

Not all number 7 plastics are polycarbonate, a handful are even plant-based. Polycarbonate has become the axis of dispute in recent years, as it is discovered to leach BPA (bisphenol A), a hormonal disruptor that may disastrously influence gestation and fetal growth.
