The demon named 'Plastic'

Hi,
In today's world we do not give a thought before we use plastic. We cannot think our lives without plastic as we cannot think our lives without oxygen. But it is very necessary to understand that plastic is a very big monster for environment. It not only stays on earth for 25,000 years but also it takes a hell lot of resources to create just a kg of plastic. And while creating also, it generates a lot of hazardous materials for our mother earth. I've given an account on what it takes to create a kg of plastic. So, from next time think before buying a plastic bottle every time you travel or asking a plastic bag for each item you buy at a store.

Total Gross Energy (in kilowatt-hours) to Produce 1 Kg Plastic


Average
Fuels Coal 1.08

Oil 4.43

Gas 4.63

Hydro .15

Nuclear .23

Other .03
Feedstocks Coal .003

Oil 9.22

Gas 3.51
Total Gross Energy (Fuels plus Feedstock)
23.283

Total Raw Materials to Produce 1 Kg Plastic

Raw Materials

Unit Average
Bauxite mg 310
Sodium Chloride mg 4900
Clay mg 1
Ferromanganese mg 1
Iron Ore mg 550
Limestone mg 270
Manganese mg 50
Metallurgic Coal mg 230
Sand mg 20
Water mg 17,500,000
Phosphate Rock mg 30
Total Raw Materials kg 17.51

As you can see that to just a kilo of plastic it takes a whopping 17.5 kg of raw materials (mostly water). Here we must keep in mind that we cannot use sea water so in a way we are indirectly reducing our water resources by using more and more plastic.

Now let's see the direct impact that can be measured. It includes air emissions, water emissions and solid wastes to produce a kilo of plastic.

Total Air Emissions to Produce 1 Kg Plastic

Air Emissions

Unit Average
Dust mg 3,800
Carbon Monoxide mg 18,000
Carbon Dioxide mg 2,330,000
Nitrogen oxides mg 20,200
Sulphur oxides mg 25,000
Hydrogen Chloride mg 110
Hydrocarbons mg 40,000
Organics mg 9,400
Metals mg 10
Total Air Emissions kg 2.45


Total Water Emissions to Produce 1 Kg Plastic

Water Emissions

Unit Average
COD mg 3,300
BOD mg 1,000
Sodium ions mg 1,500
Acid as H+ mg 180
Metals mg 120
Chloride Ions mg 710
Dissolved Organics mg 13,000
Suspended Solids mg 600
Detergent/oil mg 20
HydroCarbons mg 400
Dissolved Solids mg 580
Phosphate as P2O5 mg 10
Sulphate ions mg 40
Other Nitrogen mg 1
Total Water Emissions mg 21,461

This way we are not only using precious water but also we are polluting it.

Total Solid Waste to Produce 1 Kg Plastic

Solid Waste

Unit Average
Mineral Waste mg 30,000
Stags and Ash mg 9,600
Mixed Industrial mg 3,500
Regulated Chemicals mg 130
Inert Chemicals mg 1,900
Total Solid Waste mg 45,130

So friends, we need to reduce our use of plastic drastically. Please do not use any kind of plastic unless it is very necessary. Inculcate the habit of reusing the plastic bottles and bags.
Let's give back our environment something positive.

  1. Thanks buddy,
    I've been searching about this information for a long time. You've compiled a very good information.
