What do factories do to help stop pollution?

factories around the world that want to help stop pollution, have two basic options: work to check existing pollution and try to prevent future pollution. In many countries, factories are obliged to observe certain environmental laws; Others must implement their own own methods to stop pollution. Their aim is usually to minimize damage caused by existing pollutants and try to prevent further pollution by adjusting their industrial practices. The related option is to sell specific by -products such as raw materials to other industries.

Air pollution usually takes the form of smoke or smog, but sometimes pollutants are invisible to the naked eye. Dirt may include particles in the air as well as solid and liquid aerosols; Other common air pollution substances include sulfur oxides, hydrocarbons and carbon monoxide, which are produced by industrial activities such as coal burning. To stopIf contamination, the factory can modify its procedures or use differ equipment. For example, chimney filters can help stop pollution of capture of harmful substances and cleansing vapors before they reach the air. In addition, the factory, for example, could reduce carbon monoxide emissions instead of oil or coal.

water pollution damages animals and plants that live in rivers, streams and oceans. The factories can help stop pollution by processing waste water and other waste before its release into the environment. In addition, water treatment plants clean soiled water and add chemicals to be considered safe for wild animals and often for human use. In the US and abroad, international regulations are banned from ocean water. The US is also one of the many countries subject to federal legislation that mandates specific procedures against pollution.

In addition to adjusting their industrial industry, many factories seek to stop pollution by selling certain pollutants as by -products. Rather than being stored, by -products are recycled or reused as raw materials for another product. The recently documented example demonstrates the conversion of "slag", a by -product for steel production, into a useful raw material for cement production. The most important benefit for the environment was to reduce greenhouse gas emissions.

While this effort to stop pollution could alleviate some problems, they did not exclude them. For example, climate change continues to be a problem for all countries, and it is often not clear whether certain pollution measures were effective. In many industrial countries, the ultimate goal is to prevent pollution to prevent it completely than to drive it.
