The color of garbage bag is not just a matter of preference, but also has some practical reasons behind it.
1. The primary reason why garbage bags are black is to conceal the contents inside.
No one wants to see the garbage, and a black bag does an excellent job of hiding it. The dark color also helps to prevent the bag from becoming see-through over time, which is a common issue with clear or translucent bags.
2. To absorb heat.
When garbage is left in the sun, it can quickly start to decompose and produce odors. Black bags absorb more heat than other colors, which can speed up the decomposition process and prevent odors from lingering for too long.
3. Cheaper price
Black is a cheaper price than other color bags, so users prefer buying and use it more common . Also, in production, it is easy to produce and does not require any additional dyes or pigments.
However, there are also some disadvantages of using black garbage bags, such as:
1. They miggt be not environmentally friendly.
Black bags are usually made of non-biodegradable plastic, which can take hundreds of years to break down in landfills. They also contribute to greenhouse gas emissions when they are burned.
2. They are not suitable for recycling.
Black bags make it difficult for the sanitation department to sort out recyclable materials from non-recyclable ones. Clear or translucent bags allow the trash to be visible and easily separated.
