environmental waste or Waste or crap It is any excess and undesirable material, and it can mean Garbage or Trash. And in biologyWaste refers to excess materials or toxins.toxins) that come out of living organisms.

It is difficult to define what waste is. What is leftover to some people is valuable to others. Every day, the American people generate 4.5 pounds (2.05 kilograms) of waste per person, 55 percent of which is household waste.

And Waste management It is intended to control the collection, treatment and disposal of waste. Its aim is to reduce the negative impact of waste on the environment and society.

The development of industry and its progress led to more by-products, whether in the form of gases, solid waste, liquids, or semi-solids that were thrown into the water, air, or on the ground.

As it is known, the transformation of raw materials into complete or semi-complete industrial products, when these by-products do not find a degree of benefit on the economic level, they are thrown on the ground, water or air.

One of the most important wastes that pollute man or his environment is industrial waste, especially if it was not treated before being dumped outside the factories. When the waste is dumped near the factory without movement, the wind carries the gases coming out of it, and perhaps parts of it, to far places, and some of these gases are toxic and can affect health. humanity.

environmental influences[عدل]

Solid industrial waste such as food waste and fruit and vegetable peelings are collected insects Which transmit toxins and diseases to where it extends and move to densely populated places, in addition to the fact that these wastes pollute the air with the gases emitted from them or the smoke resulting from their combustion.

The danger of waste lies when it is associated with water that may reach it and cause pollution underground water In addition, it is considered a breeding ground for organisms for diseases such as mice cockroaches andflies. If the necessary precautions are not taken when burning waste, it leads to land pollution instead of air pollution. The presence of organic materials in the waste leads to their biological decomposition by microbes, such as bacteria. This decomposition results in toxic liquid and gaseous substances, such as oxides of nitrogen, sulfur dioxide and nitrogen, as well as the proliferation of harmful insects, which leads to contamination of the surface soil and affects the quality of the soil. Groundwater, raising the acid content in it, which makes the soil unsuitable for germination. On the other hand, the accumulation of waste, especially solid waste, leads to the occupation of large areas of land. This prevents their exploitation in agriculture or construction, as it distorts the aesthetic and urban landscape of the areas in which they are located and affects the health and psychological health of the public.

The dangers of waste to public health[عدل]

The accumulation of waste, whether domestic, industrial or commercial, without being treated or completely disposed of, constitutes a source of danger threatening the health of the people. Heaps of garbage encourage the multiplication of bacteria, germs, viruses and rodents, which leads to the spread of diseases and the spread of deadly epidemics. Unless waste is completely isolated from the human food cycle and treated to stop bacteria from multiplying.

waste components[عدل]

Most of the waste consists of the following materials:

• Leaves – Newspapers, office papers, packaging materials.
• plastics Beverage cans, packaging materials (bags).
• metals – Boxes, devices, building materials.
• glass Windows, bottles.
• feces
• timber – Furniture, building materials, panels.

Environmental compatibility system with waste[عدل]

In unscientific dealing with waste, environmentally incompatible forms of waste disposal appear, which causes complex problems and does not provide practical solutions to them. Some of the incompatible methods are:

cremation[عدل]

The burning method involves many risks, the most important of which is the pollution of the air with the products of burning various raw materials, which may include plastic materials. Which releases toxic gases and fumes into the atmosphere. It also produces a toxic liquid polluting the environment as a result of waste fire. As well as wasting the economic value of reusable elements and components inside the garbage.

landfill[عدل]

Landfilling is burial, and one of its risks is the generation of toxic liquids from the buried waste that pollute the soil and groundwater. Also, landfilling does not prevent rats and insects from leaking waste through tunnels that leak foul odors and methane gas, and in which insects, carriers of various diseases, multiply.

Throwing in sewers and bodies of water[عدل]

It is the main cause of pollution of the waters of rivers and seas. The Mediterranean Sea receives 14.2 million tons of toxic waste annually, either directly from the wastes of the industries of the countries bordering it – especially the European countries and Egypt – or indirectly from the river water that drains into the Mediterranean – Especially the Nile River-, including water of more than 16 billion cubic meters of agricultural and sewage water that reaches the northern lakes of Egypt and then to the Mediterranean Sea connected to them through the gorges.
