Waste management (or waste disposal) includes the activities and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment and disposal of waste, together with monitoring and regulation of the waste management process.
Waste management deals with all types of waste, including industrial, biological and household. In some cases, waste can pose a threat to human health.
Waste is produced by human activity, for example, the extraction and processing of raw materials.]
Waste management is intended to reduce adverse effects of waste on human health, the environment or aesthetics.
Zero Waste is a whole system approach to resource management centered on reducing, reusing, and recycling.
Zero waste management means the holistic concept of waste management which recognizes waste as a resource produced during the interim phase of the process of resource consumption. Zero waste strategies may be applied to companies, to communities, industrial sectors, to schools, and homes since they include many stakeholders, not only those of the environment, but also technological aspects.
Proper management of waste is important for building sustainable and livable cities, but it remains a challenge for many developing countries and cities.
There are 5 types of wastes:
1. Liquid Waste
- Liquid waste is commonly found both in households as well as in industries. This waste includes dirty water, organic liquids, wash water, waste detergents and even rainwater.
2. Solid Rubbish
- Solid rubbish can include a variety of items found in your household along with commercial and industrial locations.
- These can be; Plastic waste which consists of bags, containers, jars, bottles and many other products that can be found in your household. Plastic is not biodegradable, but many types of plastic can be recycled. Plastic should not be mix in with your regular waste, it should be sorted and placed in your recycling bin.
- Paper/card waste which includes packaging materials, newspapers, cardboards and other products. Paper can easily be recycled and reused.
- Tins and metals which can be found in various forms throughout your home. Most metals can be recycled.
- Ceramics and glass which can easily be recycled.
3. Organic Waste
- Organic waste is another common household. All food waste, garden waste, manure and rotten meat are classified as organic waste. Over time, organic waste is turned into manure by microorganisms. However, this does not mean that you can dispose them anywhere.
- Organic waste in landfills causes the production of methane, so it must never be simply discarded with general waste.
4. Recyclable Rubbish
- Recyclable rubbish includes all waste items that can be converted into products that can be used again. Solid items such as paper, metals, furniture and organic waste can all be recycled.
- If you’re unsure whether an item is recyclable or not, look at the packaging or the diagrams on the lid of your yellow recycling bin. Most products will explicitly state whether they are recyclable or not.
5. Hazardous Waste
- Hazardous waste includes all types of rubbish that are flammable, toxic, corrosive and reactive.
-These items can harm you as well as the environment and must be disposed of correctly.
