1. What kind of building materials you would prefer in your town? (evaluation according the chosen materials- more ecofriendly, recycled- better mark)

-In my town I would prefer many kinds of building materials, such as clay, rocks, sand and wood, even twigs and leaves, used to build buildings. Some of materials are easy to process.

2. What kind 2. What kind of processing machines are preferred (for material production and construction) (fuel, level of energy consumption, noise level environmental impact...)of processing machines are preferred (for material production and construction) (fuel, level of energy consumption, noise level environmental impact...)

-We prefer normal processing machines. The machines don't consume much fuel and they aren't harmful to the environment.

3. What is the ecological impact of the produced and applied materials in buildings?

-When we talk about ecological impact of the produced and applied materials in buildings, then there is no reason to worry. A lot of materials are natural and just 15% of them are harmful to the environment.

4. Durability of the applied materials -importance?

-The applied materials are durable. Natural disasters are the main cause of the destruction of the buildings in which the materials are used.

5. Recyclability of the applied building materials?

- Recycling construction materials has two main environmental benefits: it saves energy and it reduces landfill waste.

Energy Savings: Recycling saves large amounts of energy, and in general it decreases the consumption of natural resources to produce new materials. For example, if all the concrete and asphalt waste generated annually in the US were recycled, it would save the energy equivalent of 1 billion gallons of gasoline.
