Impact of Plastic bags:

Impact of Plastic bags:
•    take over 400 years to biodegrade and result in a large amount rubbish in our landfills
•    Air pollution is caused during incineration
•    Manufacture add many tons of carbon and other toxic chemicals into the atmosphere annually
•    Approximately 60-100 million barrels of oil are required for manufacture annually
•    Stray bags pollute much of our environment and cause 100000 marine organisms death each year
•    Small particles given off during breakdown accumulate in ecosystems and contaminate the food web
Impacts of paper bags:

 

•    Use four times as much energy as plastic bags to produce
•    Many toxic chemicals are used in the production, contributing significantly to air pollution
•    The impact production on forests is enormous as millions of trees are cut down for production
•    Consumes 9 times as much energy to recycle compared to a plastic one
•    Due to the lack of water, light and oxygen in today’s landfill, paper does not degrade at a faster rate than plastic yet takes up much more space
Impacts of jute bags:
•    Greatest financial production costs
•    Production uses and produces large quantities of chemicals, notably CH4
•    Production uses more than 7 times as much water as plastic production
•    High energy usage related to transportation
•    Negative impacts on human workers with respiratory illnesses, skin disorders and cancer prevalent as the result of exposure to NO, NH4, CO2 and spending long hours in waist deep water during retting.
It may be easy to say that plastic bags are the most environmentally harmful choice but in fact the production costs of paper and jute are significantly higher and gives plastic a slight edge in this stage. However, plastic bags are difficult to dispose of and generally are the most harmful once they have been used. While plastic represents just 0.3% of household waste, paper uses significantly more space of landfills.  The fact that paper degrades quite slowly in a landfill situation counts against it. The result is that reusable jute bags triumph over single use paper and plastic bags. While the embodied energy of jute bags is higher, the fact that many people will use a single jute bag over several years results in it being the most ecofriendly. Also in jute’s favour is the fact that it is readily compostable and recyclable which results in the lowest environmental impact.

Environmental Impact of Plastic Bags

More and more people around the world are becoming aware of the environmental issues surrounding plastic bags. Considering their somewhat placid appearance, the impact of plastic bags on the environment can be devastating.
Here are some facts about the environmental impact of plastic bags:

• Plastic bags cause over 100,000 sea turtle and other marine animal deaths every year when animals mistaken them for food

• The manufacture of plastic bags add tonnes of carbon emissions into the air annually
• In the UK, banning plastic bags would be the equivalent of taking 18,000 cars off the roads each year
• Between 500 billion and 1 trillion plastic bags are used worldwide each year
• Approximately 60 - 100 million barrels of oil are required to make the world’s plastic bags each year
• Most plastic bags take over 400 years to biodegrade. Some figures indicate that plastic bags could take over 1000 years to break down. (I guess nobody will live long enough to find out!). This means not one plastic bag has ever naturally biodegraded.
• China uses around 3 billion plastic bags each day!
• In the UK, each person uses around 220 plastic bags each year
• Around 500,000 plastic bags are collected during Clean Up Australia Day each year. Clean Up Australia Day is a nationwide initiative to get as many members of the public to get out and pick up litter from their local areas. Unfortunately, each year in Australia approximately 50 million plastic bags end up as litter.

Here are some of the harmful effects of plastic bags:

Plastic bags litter the landscape. Once they are used, most plastic bags go into landfill, or rubbish tips. Each year more and more plastic bags are ending up littering the environment. Once they become litter, plastic bags find their way into our waterways, parks, beaches, and streets. And, if they are burned, they infuse the air with toxic fumes.

Plastic bags kill animals. About 100,000 animals such as dolphins, turtles whales, penguins are killed every year due to plastic bags. Many animals ingest plastic bags, mistaking them for food, and therefore die. And worse, the ingested plastic bag remains intact even after the death and decomposition of the animal. Thus, it lies around in the landscape where another victim may ingest it.

Plastic bags are non-biodegradable. And one of the worst environmental effects of plastic bags is that they are non-biodegradable. The decomposition of plastic bags takes about 1000 years.

Petroleum is required to produce plastic bags. As it is, petroleum products are diminishing and getting more expensive by the day, since we have been using this non-renewable resource increasingly. Petroleum is vital for our modern way of life. It is necessary for our energy requirements – for our factories, transport, heating, lighting, and so on. Without viable alternative sources of energy yet on the horizon, if the supply of petroleum were to be turned off, it would lead to practically the whole world grinding to a halt. Surely, this precious resource should not be wasted on producing plastic bags, should it?
