Q & A

What is the primary focus of Environmental Engineering?

The primary focus of Environmental Engineering is to solve the world's biggest environmental problems, such as ensuring access to clean water, managing waste, controlling pollution, and developing sustainable energy solutions.

How do Environmental Engineers address the challenges posed by increasing populations?

Environmental Engineers assess the impact of increasing populations on resource availability and work to ensure that everyone has access to essential resources like clean water and energy, while also protecting the environment for future generations.

What role do Environmental Engineers play in renewable energy?

Environmental Engineers evaluate and promote renewable energy sources like solar, wind, and hydroelectric power, ensuring that their development is sustainable and minimizes negative environmental impacts.

What is the significance of the payback period in renewable energy solutions?

The payback period is crucial because it assesses the time it takes for the energy savings from renewable technologies to outweigh their environmental costs during production. A short payback period means the technology is more beneficial in the long run.

Why is the production of cement a concern for Environmental Engineers?

Cement production is responsible for around 7% of annual carbon emissions, making it a significant environmental concern for Environmental Engineers who aim to reduce the carbon footprint associated with construction materials.

How does recycling aluminum contribute to environmental sustainability?

Recycling aluminum saves about 95% of the energy required to produce new aluminum from raw materials, significantly reducing carbon emissions and energy consumption, which is a focus area for Environmental Engineers.

What historical environmental disasters do Environmental Engineers study?

Environmental Engineers study disasters like the BP Oil Spill and Chernobyl to understand the ecological impacts and develop strategies for recovery and safety assessment in affected areas.

How do Environmental Engineers collaborate with other disciplines?

Environmental Engineers work closely with Civil Engineers, Mechanical Engineers, and Scientists to design and implement sustainable solutions, ensuring that sustainability is integrated into the planning and execution of engineering projects.

What is BREEAM, and why is it important?

BREEAM is a certification body that assesses the sustainability of buildings based on their construction, operation, and demolition processes. Environmental Engineers use BREEAM to ensure that projects meet high environmental standards.

What is the overarching goal of Environmental Engineers regarding Earth's resources?

The overarching goal of Environmental Engineers is to create a sustainable future by understanding that infinite growth on a finite planet is impossible, and they work to ensure a healthy and green planet for future generations.
