Waste management includes all activities and actions required to correctly and adequately manage waste from inception to disposal. Sanitary collection engagement consists of the collection, transportation, treatment, and final disposal. It is done in the household, biological, and industrial settings.
Steps Involved in Waste Management
Decades passed, and the discharge of hazardous substances into water bodies has already killed a considerable percentage of aquatic life. And when not done correctly, it can also pollute the soil as well as the groundwater. And these are the reasons why the proper management of sanitary waste in this modern world is crucial.
Here are the steps included in these processes:
Reduction of Wastes.
The first step of the process is the reduction of waste. Any industry can achieve this through source reduction, concentration, and segregation. You must know what entails each function to understand them fully.
- Source Reduction. With source reduction, the use of raw materials and reducing the number of hazardous wastes to the minimum is where the focus is, especially in the industrial setting.
- In this process, wastes are generated are concentrated using various methods like decantation and precipitation techniques. In this step, the volume of garbage is regulated and reduced to a manageable amount.
- This is the step where the wastes are being segregated based on their chemical composition, their hazard potential, and their physical nature.
Waste Recycling Process.
Although they are ll waste materials, you can still recycle some of them. Recycling is the method where wastes can be further used. When you say recycling, it usually refers to two processes – reusing and recycling. Reusing the waste is when it is used again with little to no processing involved. Recycling, on the other hand, is waste materials that need to be treated and re-processed.
Treatment of Wastes.
The next in this four-step process is treatment. Hazardous sanitary wastes are treated using various methods. From physical, biological to chemical aspects, these treatments are made to reduce or even neutralize their toxicity levels.
- Physical Treatment. For material wastes, this is the process where mechanical separation and segregation happens. And for liquid wastes, the process involves phase separation.
- Chemical Treatment. When it comes to hazardous wastes, they are treated using various chemicals to neutralize and remove the toxicity. The treatment will involve changing the chemical properties.
- Biological Treatment. Bacteria and fungi are just some of the microorganisms that break down the organic substances that are present in the waste matter. The process involves conditioning, digestion, and composting.
Waste Disposal Process
As the final step of waste management, it involves the proper disposal. To do this, it follows a specific process – the recogida de residuos sanitarios or the collection of sanitary wastes, providing temporary storage of these wastes, and their transport. These are the pre-requisites depending on the chemical properties and nature of the waste products.
Understanding the step-by-step of proper waste management is crucial. It is done in the household, commercial, and industrial settings. Without these processes, more and more waste materials will be dumped in places where they can significantly damage the environment.
