Plastic is a big problem of our country and world. But the plastic is only material which is very use full for daily use purpose of every person. Like the use of plastic in transport any material, protect from water, for covering  of any substance,  for store of material, for use as insulating material and other purpose. Therefore we say plastic is very useful and we use it every day. But due to use and throw of plastic is causing a big problem of our planet. It’s thought more than five trillion pieces of plastic are in the world’s oceans and it can take years for it to break down. But isn’t biodegradable, due to this property of plastic create so many problem on our earth. Increasing of green house gas effect. Due to its,  increasing land pollution, air pollution, ground water pollution, due to its,  hurt of animals and etc. Due to its Poisson property,  the all cycles of environment are affected. There for the decreasing of plastic use and recycle of it is very important.
The Prof Rajagopalan Vasudevan is plastic man of india. His innovative thoughts is try to reduce plastic and recycle it. Which is very helpful for our environment. The Prof  Rajagopalan Vasudevan is chemistry professor at ThiagarajarCollege Of Engineering, Madurai.

This man constructs a road by using plastic waste. This road is known as plastic road. The plastic waste items that can be used for road construction are various items like plastic carrybags, plastic cups, plastic packaging for potato chips, biscuits, chocolates, etc.

Plastic roads are made entirely of plastic or of composites of plastic with other materials. Plastic roads are different from standard roads in the respect that standard roads are made from asphalt concrete, which consists of mineral aggregates and asphalt. Currently, there are no records of regular roads made purely of plastic.  Plastic composite roads, however, have existed and demonstrate characteristics superior to regular asphalt concrete roads; specifically, they show better wear resistance.  The implementation of plastics in roads also opens a new option for recycling post consumer plastics. AustraliaIndonesiaIndia, the United Kingdom, the United States, and many other countries have used technology which can incorporate plastic waste into an asphalt mix. The plastic waste items that can be used for road construction are various items like plastic carrybags, plastic cups, plastic packaging for potato chips, biscuits, chocolates, etc.

PROCESS :-

Process involve for constructing plastic roads are given below.
a) collecting waste plastics, including plastic carry bags, cups, soft and hard foams, and laminated plastics.
b) cleaning it by washing.
c) shredding it to a uniform size.
d) melting the waste plastics at 165°C, and blending it with hot aggregates and bitumen and using this mixture to lay the road.

SHREDDED PLASTIC MATERIAL USE IN PLASTIC ROAD

The entire process is very simple. The plastic waste material is first shredded to a particular size using a shredding machine. The aggregate mix is heated at 165°c and transferred to the mixing chamber, and the bitumen is heated to 160°c to result in good binding. It is important to monitor the temperature during heating.

The shredded plastic waste is then added to the aggregate.  It gets coated uniformly over the aggregate within 30 to 60 seconds, giving an oily look. The plastic waste coated aggregate is mixed with hot bitumen and the resulting mix is used for road construction. The road laying temperature is between 110°c to 120°c. The roller used has a capacity of 8 tons.

CONCEPT:-

1.     Prefabricated and modular.
2.     Hollow design.
3.     Sustainable.
    1.) Prefabricated And Modular :-
          The Plastic Road concept consists of a prefabricated, modular and hollow road structure based on (recycled) plastics. Due to prefabricated, the plastic road light in weight easy to construct. Due to modular design of plastic road it is easy to maintenance and established.)

   2.)Hollow Design :-
The hollow design is very helpful for store of  water, thus preventing flooding during extreme precipitation. This hollow space also can be used for transmit wires, cables and pipe between it.
     3.) Sustainable :-
The PlasticRoad is a completely circular product that is based on recycled plastics. It has a significantly smaller carbon footprint than traditional road structures thanks to the longer lifespan and the reduction of transport movements involved in its construction.

WASTE SINGLE USE PLASTICS
OBJECTIVE OF PLASTIC ROAD:-
  1.              The objective is primary to reduce plastic waste – bags, bottles. Not all plasticwaste is recycled, as even the recyclable waste is just too much to reuse 100%. But bituminous roads are continuously being built and can incorporate extremely large quantities of plastic waste. Saving in cost is a bonus.
  2.           The expected lifetime of the plastic road is two to three times as long as that of traditional road paving.
  3.        The expected construction time of a new road will be reduced by approximately 70%.
  4.         The plastic road is four times as light in weight compare as a traditional road structures.
  5.         The plastic road is 100% circular and is made from recycled plastic as much as possible.

ADVANTAGES OF PLASTIC ROAD:-

·        This road construction process is extremely eco-friendly, with no toxic gases being released.

  •         This process has generated an additional job for rag pickers.
  •         Plastic waste helps increase the strength of the road, reducing road fatigue.
  •         These roads have better resistance towards rain water and cold weather. 
  •         Since a large amount of plastic waste is required for a small stretch of road, the amount of waste plastic strewn around will definitely reduce.
·        A lightweight prefabricated construction.
·        Faster construction and less maintenance time.
·        Higher quality and a longer lifespan.
·        Little to no maintenance required. The material is virtually impervious to conditions such as the weather and weeds.
·        The innovation is considerably more sustainable.
·        The goal is to make the Plastic Road out of 100% recycled plastic and to make it fully reusable. It is perfectly in line with the Cradle to Cradle philosophy and the principles of the circular economy.
·        Double use of space. The hollow space in the design can be used to store water or as space for cables and pipes.
·        The possibility of constant safety and water drainage
·        Everything on and around the road can be prefabricated .
·        The concept offers opportunities for further innovation. Examples include solar heated roads, light poles and traffic loop sensors.
·        Contribution to the social problem of plastic waste.

DISADVANTAGES OF PLASTIC ROAD

  • Toxic present in the co-mingled plastic wastes would start leaching.
  • But the presence of chlorine will definitely release HCL gas.

INDIA:-

®   Chennai was among the first cities globally to adapt the technology in a big way when the municipality commisioned 1000km of plastic roads in 2004. Since then all major municipalities in India have experimented with the technology including  Pune  Mumbai Surat Indore  Delhi,  Lucknow etc
®   Chennai: While the plastic roads may be a new concept in many parts of India, Chennai has been experimenting with it since 2011. Chennai has used nearly 1,600 tonnes of plastic waste to construct 1,035.23 kilometres length of roads in recent years, which include N.S.C Bose road, Halls road, Ethiraj Silai Street and Sardar Patel Street.
®  Pune: Using bitumen technology on waste plastic, the Pune Municipal Corporation constructed a 150-metre stretch of Bhagwat lane at Navi Peth near Vaikunth Crematorium in 2016. The other trial patches in Pune include Dattawadi Kaka Halwai Lane, Katraj Dairy, Magarpatta City HCMTR Road, Kavde Mala Road, Koregaon Park Lane No 3 and Yeravada Sadal Baba Darga Road from Chandrama Chowk.
®  Jamshedpur: Jamshedpur Utility and Services Company (JUSCO), which is a subsidiary company of Tata Steel, constructed a 12-15 kms road in the steel city as well as Tata Steel Works using plastic road, including a nearly 1km stretch in Ranchi, 500m stretch each in Dhurwa and Morabadi, 3km of roads in Chas and Jamtara each and 500m stretch in Giridih.
®   Indore: Dating 2014, the Madhya Pradesh Rural Road Development Authority (MPRRDA) has constructed around 35 km of roads in 17 districts with plastic waste.
®   Surat: The idea of using plastic-bitumen mix was executed in January 2017. The problem of potholes significantly reduced as no cracks developed in areas where roads were layered with waste plastic.
®   The technology has penetrated deeply and has found application even in far flung areas such as Meghalaya, where a village converted 430kgs of plastic waste into a kilometer long road in 2018.
