Question

Which of the following is not an eco-friendly building material product ?

• A. Bagasse Board
• B. Pre-cast slabs
• C. CF1 lamps
• D. Petroleum

Hint:

Sustainable building design focuses on using materials derived from agricultural waste (like bagasse) and local, renewable sources to minimize the carbon footprint of construction.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Green building practices prioritize the use of sustainable, renewable, and non-toxic materials that minimize environmental impact throughout their lifecycle.

Step 2: Detailed Explanation:
Let us evaluate each material listed:
1. Bagasse Board: This is made from the fibrous residue left after crushing sugarcane stalks. It is a highly sustainable, renewable, and biodegradable agricultural byproduct used as an eco-friendly alternative to wood for partition boards and ceiling panels.
2. Pre-cast slabs: These are concrete elements cast and cured in a controlled factory environment before being transported to the construction site. This process reduces material waste, water consumption, and onsite pollution, making them more eco-friendly than cast-in-situ concrete.
3. CFL (Compact Fluorescent) lamps: These are energy-efficient lighting products that consume significantly less electricity and last longer than traditional incandescent bulbs, helping to conserve energy.
4. Petroleum: This is a non-renewable fossil fuel.
Its extraction, refining, transport, and combustion cause severe environmental damage, including greenhouse gas emissions, oil spills, and air pollution. It is not an eco-friendly material or product.

Step 3: Final Answer:
Petroleum is not an eco-friendly material or product, corresponding to option (D).
