Biodegradable substances affect the environment in the following ways:
- Biodegradable substances such as tree leaves, plant parts, and kitchen wastes can be used as humus after composting. This will enhance soil fertility.
- The biodegradable substances mainly contain carbon. These substances after decomposition release that carbon back into the atmosphere.
- They may produce foul smell during the decomposition process.
- Waste decomposing in landfills produces harmful methane, a gas that’s 100-120 times more powerful than carbon dioxide at the time of emission.
