Biodegradable garbage refers to organic garbage that can be gradually decomposed, degraded and transformed into water, carbon dioxide, organic fertilizer, etc. in the natural environment. Such as vegetables, fruits, bread crumbs, napkins and so on belong to biodegradable garbage.
Treatment of biodegradable garbage
1. Stacking
Biodegradable garbage can be piled up on a suitable site and allowed to decompose and degrade naturally, and eventually be converted into useful substances, such as fertilizers. Piling is simple and convenient, and is suitable for rural or urban areas with beautiful environments.
2. Composting
Composting is a treatment method that classifies and mixes organic waste to form organic fertilizer through the action of decomposing bacteria. Specifically, biodegradable waste is mixed with wood chips or straw, etc., and after many weeks or even months of fermentation, the resulting compost can be used as organic fertilizer for plant growth. This method is suitable for citizens living in urban environments, who can set up composting points at home or in public places to make their own compost, and at the same time reduce the environmental pollution caused by domestic waste.
The role of biodegradable waste disposal
1. Reduce the cost of garbage disposal
Biodegradable garbage does not need to be put into the garbage treatment plant for classification and processing, so it can reduce the cost of garbage treatment and lower the burden on the society.
2. Reduce and improve the land environment
After being processed, biodegradable waste becomes fertilizer and soil conditioner, which can also improve the land quality and land environment and make the land more fertile.
3. Reduce pollutant emission
Biodegradable garbage is naturally decomposed through the process of piling and fertilizing, and does not produce the same large amount of dust, pollutants or greenhouse gases as traditional garbage disposal.
