WASTE MANAGEMENT and ROAD NETWORK of a county effects each and individual citizens within. Because waste management is directly related to health of society and Roads matter for connectivity, transportation and availing resources which are not present in particular locality.
What if I say, Both the problems can be curbed by 1 solution. Yes. That’s right, Making roads from PLASTICS. And not from virgin plastics, but from plastic waste which we generate as lamination films, biscuits / chips /chocolates’ wrappers, carry bags, disposed containers etc.. ..
The technology goes back to 20th century, Polymer modified asphalts became popular in late 1970s in Europe. At the initial stages only virgin plastics were used for making these types of polymer-asphalt compounds which resulted to non viability in practical use.
Making roads from Plastic scrap is kind of newer technology, thus there are no any particular methodology to it. Many companies using different methods to achieve desirable results.
The PLASTIC MAN of India Prof. Rajagopalan Vasudevan who invented very low cost method for plastic roads and he implemented use of plastic waste in road in 2002 at his collage campus. According to him method is as follows.
- STEP 1 : Segregating plastic waste from the solid waste.
- STEP 2 : Than shredded into small pieces using industrial plastic shredders.
- STEP 3 : Shredded plastic waste is heated at upto 165 Deg. Cel. temperature and transferred to mixing chambers
- STEP 4 : Bitumen, heated at 160 Deg. Cel. is mixed with plastic melt and mixed thoroughly
- STEP 5 : Lying road with tempreature range between 110 Deg. Cel to 120 Deg. Cel. with used roller of 8 tonnes capacity.
Main advantages plastic roads offer are Long Durability, Water Resistance, Reducing Voice Pollution, Can withstand high temperature as well as high loads and we get to save some resources too… !!!!
According to Prof. Vasudevan
“THE ADVANTAGES OF USING WASTE PLASTICS FOR ROAD CONSTRUCTION ARE MANY. THE PROCESS IS EASY AND DOES NOT NEED ANY NEW MACHINERY. FOR EVERY KILO OF STONE, 50 GM OF BITUMEN IS USED AND 1/10TH OF THIS IS PLASTIC WASTE. THIS REDUCES THE AMOUNT OF BITUMEN TO BE USED. PLASTIC INCREASES THE AGGREGATE IMPACT VALUE AND IMPROVES THE QUALITY OF FLEXIBLE PAVEMENTS. WEAR AND TEAR OF THE ROAD IS DECREASED TO LARGE EXTENT”
Plastics roads are highly versatile too. Many cities are using plastic roads as per their particular requirements.
For example Illinois use them for High Traffic Truck Roads, Washington State use them for voice reduction purpose, In rural Orianto they are used to prevent crackings on the roads after harsh winter. In southern India, State of Tamilnadu use them for long durability of the road.
Thus, being Eco-friendly solution, many counties are starting to pave the way forward with plastic roads,
In UK engineer named Toby McCarthey has first introduced plastic road replacing bitumen with pieces of plastic waste. As a results those roads were 60 % stronger than conventional bitumen-tar roads. Netherlands are also in the list using ocean waste in road infrastructure. Ghana / Bhutan have also adopted the Eco-friendly technology, But India is performing quite impressively.
JAMBULINGAM Street of Nandangakkam area of City, Chennai( State:Tamil Nadu) is one of the earliest plastic road projects in India. Those “PLASTIC TAR” made road have not developed any potholes or rutting or raveling even after 4 years of age. Since than India leaned towards this approach with higher seriousness
In India about 39,000 Kms ( Approx 21000 Miles) of roads have already by used Plastics waste. Out of which roughly half are in the southern area of state Tamil Nadu. Mostly are in the rural areas. Small numbers of roads with plastics are in Chennai and financial capital Mumbai as well. Remaining are in Jamshedpur, Himachal Pradesh, Bangalore etc.. .. ..
In eastern India, The JAMSHEDPUR UTILITY & SERVICES COMPANY (JUSCO) a subsidery company of TATA Steel has unique patented technology of these types of roads. JUSCO has constructed around 15 Km roads in STEEL CITY, Jamshedpur and widened 22 roads using this technology.
Mr. Gaurav Anand, Senior Manager (Quality Assurance) JUSCO, who is also and environmental engineer has said that there are no maintenance cost for first 5 years. He also said that for every Kilo metre and four metre wide road using this technology one tonne of Bitumen is saved. Worth 50,000 Rs. The bitumen use is reduced 7% since JUSCO has taken this initiative. Anand said, longevity of these types of roads are two times better than conventional bitumen roads.
According to Times Of India The National Highwy Authority of India (NHAI) is planning to utilize solid waste from Ghazipur landfill site in construction of Delhi-Meerut expressway. This will be in line with Prime Minister Narendra Modi‘s direction for utilizing waste in productive ways
As current BJP Government of India has allocated 13,948 Crore Rs. on ‘Swachchh Bharat Abhiyan’ (Translate as : “CLEAN INDIA MISSION) and multi-million km of Indian road network, Industrialists and environmentalist are expecting more projects to be announced for Plastic waste Roads.
Do you think this alternative can help us get rid of Plastic Waste????
