Engineering in business and the environment Lesson 4: Environmental effects of engineering activities
Objectives for this lesson to be able to identify the environmental effects of engineering activities.
Environmental effects energy use - efficiency raw materials emissions social effects
Energy electrical – efficient machinery and lighting heating – modern heating plant – insulation – heat recovery transport – minimise mileage by efficient route planning use more efficient processes.
Raw materials minimise waste process efficiently recycle waste select materials to minimise waste
Emissions water – treat waste – change process to minimise air – filter particles – change process to minimise solid waste – find a beneficial use for waste.
Social effects traffic noise in residential areas traffic congestion during rush hour process noise at night transport of raw materials and finished products (road, rail, air, sea) pollution of the environment employment – earnings for local people.
Review objectives to be able to identify the environmental effects of engineering activities.
