Waste can be classified by a multiple scheme. With the exception of source or origin, list them. (5 marks) (ii) Identify and explain four (4) types of waste by source (origin) ( domestic, commercial, agricultural and industrial

Waste can be classified through various schemes, including: 1. **Physical State**: Solid, liquid, or gas. 2. **Hazardous Nature**: Hazardous or non-hazardous. 3. **Degradability**: Biodegradable or non-biodegradable. 4. **Composition**: Organic or inorganic. 5. **Frequency of Generation**: Continuous or intermittent. ### (ii) Four Types of Waste by Source (Origin) 1. **Domestic Waste**: - **Definition**: This type of waste is generated from households and residential areas. - **Examples**: It typically includes food scraps, packaging materials (plastic, paper), old clothing, and general rubbish. - **Characteristics**: Domestic waste is usually mixed, consisting of both biodegradable and non-biodegradable materials. A significant portion is organic matter, which can be composted. 2. **Commercial Waste**: - **Definition**: Waste produced by businesses and commercial establishments. - **Examples**: This includes waste from offices, shops, restaurants, and hotels, such as packaging materials, food waste, old furniture, and paper waste. - **Characteristics**: It can be more structured than domestic waste due to the nature of businesses’ operations, often involving more packaging waste and consumer goods. 3. **Agricultural Waste**: - **Definition**: Waste generated from agricultural activities. - **Examples**: This waste may include crop residues (like straw and husks), animal manure, and discarded agricultural chemicals. - **Characteristics**: Agricultural waste is often organic and can be reused or transformed into bioenergy or compost, though it can also contribute to pollution if not managed properly. 4. **Industrial Waste**: - **Definition**: Waste produced by manufacturing and industrial processes. - **Examples**: This includes waste materials from factories, such as scrap metal, chemical by-products, and waste oils. - **Characteristics**: Industrial waste can be hazardous or non-hazardous, depending on the materials and processes involved. It often requires careful handling, treatment, and disposal to mitigate environmental impacts. Each type of waste poses unique challenges and opportunities for waste management and recycling initiatives, necessitating tailored approaches to minimize environmental impact.
