Crude oil and petrochemicals - JSS2 Basic science Past Questions and Answers - page 2
What are some environmental impacts associated with the refining of crude oil?
Environmental impacts include air and water pollution, habitat destruction, and the release of greenhouse gases. Spills and accidents during transportation and refining processes can also harm ecosystems and human health.
How do petrochemicals contribute to everyday products?
Petrochemicals serve as the building blocks for a wide range of products such as plastics, pharmaceuticals, synthetic fibers, and detergents. These materials are essential in various industries and are found in items we use regularly, including packaging, clothing, electronics, and medical supplies.
What are some alternative sources of raw materials that could reduce reliance on crude oil and petrochemicals?
Alternative sources include biomass, such as plant-based feedstocks and agricultural waste, as well as renewable energy sources like solar and wind energy. Advances in biotechnology and green chemistry are also enabling the development of sustainable alternatives to traditional petrochemical-based products.
