Question

What environmental problems are associated with the manufacture of cement?

1) acid rain
2) large amount of by-products
3) mining operations
4) high-energy consumption
5) air pollution
6) crushing operations of particulate matter

Answer 1

Cement manufacture poses environmental problems such as contributing to air pollution, acid rain, and greenhouse gas emissions, damaging ecosystems through mining operations, producing particulate matter, and generating large amounts of by-products.

Step-by-step explanation:

The manufacture of cement is associated with several environmental problems. Firstly, it contributes to air pollution and acid rain due to the release of sulfur dioxide and nitrogen oxides during the heating process. These emissions occur because cement production often involves the burning of fossil fuels like coal.

Secondly, the process is energy-intensive, leading to high levels of carbon dioxide emissions, a greenhouse gas contributing to global warming. Thirdly, mining operations for raw materials used in cement production can lead to habitat destruction and biodiversity loss.

Also, the crushing operations during manufacturing release particulate matter into the air, which can affect air quality and human health. Lastly, cement manufacturing can generate a large amount of by-products, which may pose disposal and management challenges, contributing to land degradation and pollution.
