Waste management involves the collection, transport, treatment and disposal of hazardous waste. It also involves the recovery of materials and energy from these discarded wastes for further use.
The main goal of Waste management is to prevent the environmental impact caused by waste. This is achieved by reducing the quantity of waste and increasing the recycling of waste products. Waste management is a vital step in ensuring that the environment remains safe and healthy for everyone.
To achieve the best results, it is essential to have a well-established waste management system in place. This includes the creation of a clear set of measurable goals and the development of an ongoing monitoring plan to track progress. It is also necessary to keep all employees involved in the process through training, induction and toolbox talks. Lastly, it is important to enforce the correct waste management procedures within each facility.
There are several different waste management methods, with each one having its own pros and cons. Some of the most common include recycling, reusing and composting. These methods allow us to reduce the amount of waste we produce, while at the same time reusing and reducing our dependency on natural resources like trees. Another important waste management method is preventing the creation of waste in the first place. This can be done through avoiding the purchase of disposable items, repairing broken materials instead of buying new ones and using second-hand goods whenever possible.
Reducing the volume of waste materials through the use of mechanical and biological processes can help reduce landfill space and air pollution. These processes may include shredding, sorting and crushing the waste to prepare it for aerobic or anaerobic biodegradation. Alternatively, this waste can be incinerated to produce heat and electricity.
In developed countries, the third R of Waste management – Recycle – is widely practiced. This is the most effective way to avoid waste disposal and save on energy usage. It also prevents the need for new energy sources and reduces greenhouse gas emissions. It is possible to recycle paper, plastics, glass, metals and other materials.
One of the most significant forms of waste management is turning waste into useful energy. This can be done through incineration, gasification and plasma gasification. These processes turn non-recyclable materials into sustainable power sources, while minimizing their ecological impact.
Another great waste management method is feeding discarded food to animals. This can be used at both domestic and farm levels. For example, household waste such as vegetable peels and food scraps are often fed to small animals like hamsters and rabbits. Larger animal waste such as meat bones are commonly used in pig feed.
In the developing world, waste is still considered to be a liability, rather than an asset, even though it is now possible to transform waste into a valuable resource. This is partly due to a perception that if something is not useful it must be trashed. However, this type of thinking is flawed because a definition of “waste” should be defined by its relationship with an owner.
