Final answer:
Different types of waste include solid, liquid, and gaseous waste with biodegradable examples such as food and green waste. Biodegradable waste management methods comprise composting, anaerobic digestion, and landfilling. Other waste types are managed through recycling and incineration methods, all serving to mitigate land pollution and environmental impact. The correct option is a) Solid waste, liquid waste, gaseous waste; composting, anaerobic digestion, landfilling
Step-by-step explanation:
Types of Waste and Biodegradable Waste Management Methods
The different types of waste include solid waste, liquid waste, and gaseous waste. Each of these can contain biodegradable materials, which are those that can naturally decompose through the action of living organisms. Typical biodegradable waste consists of food and kitchen waste, green waste, and most paper. However, in a more general context, waste can also be classified into recyclable materials, inert waste, biodegradable waste, non-biodegradable waste, and e-waste.
For biodegradable waste management, the primary methods include composting, which is a biological process that decomposes organic matter into soil conditioner; anaerobic digestion, which breaks down organic matter in the absence of oxygen to produce biogas; and landfilling, although the latter is reduced in favor of more sustainable methods. Other general waste management techniques are recycling and incineration. Recycling involves the reprocessing of waste into new products, while incineration is the combustion of waste, which can generate energy but also produce emissions.
It is crucial to managing waste effectively to avoid contributing to land pollution and to reduce the environmental impact. By following the 3Rs of Garbage - Reduce, Reuse, and Recycle - we can minimize the amount of waste generated and conserve natural resources for future generations. The correct option is a) Solid waste, liquid waste, gaseous waste; composting, anaerobic digestion, landfilling
