Question

Discuss the role of eco-efficiency technology.

Answer 1

1. Use of alternative raw materials: e.g., agricultural residues like rice straw and wheat straw are good substitutes for wood.
2. Shifting to renewable sources of energy: Renewable sources of energy, such as biofuels, solar power, wind power, tidal power, hydropower, and geothermal power, do not create pollution and are inexhaustible.
3. Technology that reduces pollution, such as solar water heaters, solar cookers, windmills, etc., is also pollution-free. The use of CNG and unleaded gasoline in vehicles also reduces pollution.
4. Reusing and recycling waste: e.g., waste goods such as paper, glass, plastics, and metals can be recycled into new products.
