about waste management from environmental chemistry for 11th
Answers
Answer:
Studying different types of pollution and its effect has definitely made you realize the necessity to save the environment. So how can we save our immediate environment? We can achieve this by controlling environmental pollution and by the implementation of different measures, strategies, activities, and protocols. The adoption of these steps and strategies to control air, water, soil, and industrial waste pollution is nothing but waste management. Let’s study more about green chemistry in this section.
Explanation:
Waste management, also known as waste disposal, is the steps and actions taken to manage waste from the start or release of waste to end or final disposal. It includes the collection of waste, transport of waste, waste treatment and waste disposal along with regulation and monitoring of the waste disposal.
Management of waste also covers the legal and regulatory framework related to the guidelines of waste management and recycling. Waste can be present in the form of solid, liquid and gas. However, the steps to dispose and management of each form is different.
Waste management and the regulatory framework encompass every category of waste such as industrial waste, biological waste, household waste and special types of waste. Special types of waste include biomedical and radioactive waste materials. All the above type of waste have the potential to harm human health but the degree of effect may vary.
Majority of the waste products can be traced back to human activities for example waste disposal after the extraction and processing of raw materials in the industries. You may have seen the non-uniformity in the waste disposal and management practices in developing and developed countries.
Management practices also vary within a country depending upon region (rural or urban region) and sectors (industrial or residential sector). The sole purpose of waste management is to decrease the impact of the adverse effect of waste on the environment, health of living organisms, and aesthetics.
The major part of waste management is municipal solid waste management or MSW management. The bulk of MSW consists of industrial waste, waste from commercial activities and household waste. However, household waste is not the only solid waste. The waste discards originating from agricultural, medical, mining and other industrial activities falls into the solid waste category as well.
The disposal of these wastes improperly can lead to environmental pollution and degradation. Therefore, the management of wastes and proper disposal is very crucial to maintain the health of living organisms and prevent environmental degradation.
Collection and Disposal of Waste
You might have seen small dustbins around your house and even dustbins in particular places in your community. These are the small initiative to keep your house and area near you clean. Hence, the domestic waste collection is done in small bins and then it is transferred to the larger community bins. The management, establishment of community bins are overseen by private and municipal employees.
Larger vehicles move around the places and collect the discards from the community bins and discard it into the disposable site. It is the place where the waste accumulation takes place before further processing. Sorting of garbage on the basis of biodegradable substances and non-biodegradable substances take place at this site.
Non-biodegradable compounds include glass, plastic, and metal scraps which further undergo recycling process
Biodegradable compounds can easily be converted to compost. Thus, they are deposited into landfills.
