A number of rubbish in our world are increasing more and more quickly. There are 41532 tons of rubbish per day or 15 billion tons per year in Thailand. 64% are food scraps and organic, 30% are recyclable rubbish. But we recycle rubbish only 25% .If we don’t have a good way to eliminate rubbish, it will has a lot of pollution. Although we have a campaign for eliminating rubbish in correct way, the elimination is not properly formed such as burning rubbish outdoor or leaving in the river.
Now you known that overflowing rubbish is a very big problem but the main problem of overflowing rubbish is plastic bags because plastic bags can’t recycle and it use 450 million year to biodegrade. Some kind of rubbish can recycle or biodegradable but plastic bags can’t do it. To eliminating plastic bags we need to burn it but if we do that it will be cause of global warming or we can bury it but if we do that we will lose the area for agriculture because the soil in that area will be wane.
Solution to the problem
1.To reduce the problem caused by plastic bags I think everyone known that we need to reduce the use of plastic bags maybe we use cloth bags or basket instead of plastic bags if we do that just once a week we will reduce the use of plastic bags more than 100 million bags per year. On the other hand if you buy few things in supermarket you should tell the employee that you don’t want plastic bags.
2. If you are monger or merchant you should use biodegradable plastic bags. Although that kind of plastic bags is more expensive than normal plastic bags but you are the one who try to help the world. Biodegradable plastic bags are plastic bags which use only 6-12 months for biodegradable.
3. On the other hand I think most of people don’t know that plastic bags can mixed with asphalt concrete. Bringing plastic bags mixed with asphalt is the way to improve quality of asphalt concrete that asphalt concrete can get more weight. Bringing plastic bags mixed with asphalt can be done by cutting plastic bags into small piece and mix with asphalt concrete at 120°C until combined to thoroughly form. So this is an interesting way to decrease a number of plastic bags rubbish.
