What are the 6 types of solid waste?
The six types of solid waste are organic waste, recyclable waste, hazardous waste, construction and demolition waste, bulky waste, and inert waste. Each type of waste has its own unique characteristics and requires different methods of disposal and management. Understanding the different types of solid waste is crucial for effective waste management and minimizing environmental impacts.
Proper classification of solid waste is essential for developing effective waste management strategies. For instance, organic waste can be composted and used as fertilizer, while recyclable waste can be processed and reused. On the other hand, hazardous waste requires special handling and disposal procedures to prevent environmental contamination.
What is organic waste and how is it managed?
Organic waste refers to waste that is biodegradable and can be broken down naturally by microorganisms. Examples of organic waste include food waste, yard trimmings, and paper products. Organic waste can be managed through composting, which involves breaking down the waste into a nutrient-rich soil amendment.
Composting is an effective way to manage organic waste, as it reduces the amount of waste sent to landfills and creates a valuable product that can be used in agriculture and gardening.
