Waste Management and Pollution

Yucca Mountain in Nevada was designated by the U.S. government as the site for the deep geological repository for spent nuclear fuel and high-level radioactive waste.

• Insects in stored grain can cause much damage. The farmer may lose up to a third of the stored grain. 
• Large scale storage of grains is done in silos and granaries to protect them from pests like rats and insects.

The three R's of waste management are a widely recognized framework for environmental sustainability: Reduce (use less), Reuse (use again), and Recycle (process into new materials).

The producer is required initially for the availability of organic food. The consumer will consume the organic food prepared by the producer and will also make an equilibrium in the environment by being a part of the nutrient cycle. A decomposer will breakdown the dead organic from the dead bodies of producer and consumer. So, these are required in a functional ecosystem. The presence of polluter is undesirable as it would distort the environment, making it difficult for the biotic and abiotic components to keep their sustenance.

Wastes which consist of materials those are difficult to biodegrade so that destruction takes a very long time are known as inorganic wastes. Inorganic wastes come from non renewable natural resources such as minerals and petroleum, or from industrial processes. Some inorganic wastes as a whole cannot be explained by nature, while others can only be described in a very long time.

Examples of inorganic wastes- chemical solvents, paints, sandpaper, paper products, industrial by-products, metals, and radioactive wastes, sand, salt, Iron, Calcium and other mineral materials like  Arsenic.

Recycling is the process of converting waste materials into new materials and objects. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. Recycling can prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, thereby reducing: energy usage, air pollution (from incineration), and water pollution.

Wastes which consist of materials that are non-biodegradable so their destruction takes a very long time are known as inorganic wastes. Inorganic waste comes from non-renewable natural resources such as minerals and petroleum, or from industrial processes. They are only slightly affected by the action of organisms. They include waste materials such as sand, salt, Iron, Calcium, Mercury, Arsenic, Cadmium, etc.

Construction waste is defined as debris generated from the construction, renovation, and demolition of buildings and infrastructure.

Processing of solid waste is a process that involves energy recovery from the wastes. In this nonrecyclable waste is converted into usable heat, electricity or fuel through various processes such as combustion, gasification, etc. Thus it is a process of treating solid waste which can be further put into use in any form or manner.

Waste management is the process of disposing of waste in a manner that does not harm the environment unnecessarily. It involves collection that is picking up waste material from the source, segregation which involves separating of products which can be recycled from those which are toxic to reduce waste and lastly composting which involves the dumping of waste so that it can be degraded in the environment.

Fly ash is also known as pulverised fuel ash. It is one of the coal combustion products. The pneumatic system is employed for the disposal of fly ash. 

Responsible person contributes in public sanitation by following ways:

Sanitation is hygienic practices of promoting health through prevention of human contact with the hazards of wastes as well as the treatment and proper disposal of sewage or wastewater. It is the provision of drinking clean water and safe disposal of human urine and faeces. Sanitation can be emphasized even simply by personal hygiene practices such as handwashing with soap, proper household practices.

Sanitation primarily refers to the hygienic means of promoting health through prevention of human contact with the hazards of wastes. The disposal of urine and faeces is the core focus of sanitation systems.
